Gardening in the Midwest

Good acorn squash territory, though vine borer pressure varies by year. Hot, dry summers favor powdery mildew; hot, humid ones can drive disease from the soil. Start indoors for the best timing.

Amaranth thrives in Midwest summers, with sufficient heat for grain maturation in most areas. The main challenge tends to be bird pressure on ripening seed heads — netting or prompt harvest when heads turn brown usually prevents losses.

Cold winters eliminate perennial production, and the vernalization requirements make annual production challenging. Gardeners with the space and patience can succeed by starting very early indoors and choosing varieties bred for annual culture, but yields tend to be modest.

Early spring and fall crops work well. The wide temperature swings of Midwestern springs can close the spring window quickly. Fall crops are often more reliable and produce longer before frost ends them.

The Midwest's cold winters and warm springs are ideal for asparagus. Beds planted in deep, well-prepared soil often become highly productive by year five. Crown rot can occur in heavy clay; raised beds or deep loosening before planting prevents it.

Beets are reliable in the Midwest for both spring and fall crops. Spring planting 4 weeks before the last frost captures cool weather; a late-summer planting sized for fall harvest is often the sweeter crop.

Early spring and fall crops work well. The summer heat window makes succession planting essential — stop sowing at least 8 weeks before your first fall frost to allow enough season.

Spring timing is tight — transplant as early as possible and choose a fast-maturing hybrid like Green Magic to beat the heat. Fall crops from late-summer transplants are often more successful.

Spring transplanting can work if the season is long enough. In zones 5 and 6, fall frost often arrives right at the ideal harvest window. Choose faster-maturing hybrids like Jade Cross in shorter-season areas.

Excellent butternut territory. Hot summers and long frost-free periods allow full maturity on most varieties. Plant early (or start indoors) to ensure the fruit is harvested before the first fall freeze.

Spring transplanting works well in years with a long cool period. Fall crops planted in late July can yield excellent heads. Black rot can be a significant problem in humid summers.

Good melon country in most years. The heat of July and August suits cantaloupe well; choose varieties that finish before the first fall frost.

Both spring and fall crops are possible in the Midwest. Heavy clay common in parts of the region tends to cause forking; raised beds or deeply worked beds with added sand or compost tend to produce straighter roots. Carrot rust fly is occasionally a problem in northern areas.

Spring windows are tight and unpredictable. Fall crops are generally more reliable. Choose fast-maturing hybrids like Amazing for spring, and cold-tolerant types for fall.

Celeriac can be grown successfully in the Midwest with attention to watering — the variable summer rainfall often requires supplemental irrigation to keep the roots from stalling. Starting indoors in late winter and transplanting in mid-spring usually gives the plant a long enough season to reach full size by fall.

The Midwest's variable rainfall can make celery challenging without supplemental irrigation. Consistent watering matters more than in regions with steady summer rains. Spring plantings that mature before July heat tend to be more successful than those pushed into August.

Spring transplanting produces summer crops. Fall crops from mid-summer transplants hold well into October and November. The cold hardiness is a real advantage — plants often outlast the last tomato by several weeks.

Corn is native ground in the Midwest. Hot summers, fertile soils, and long frost-free seasons make it one of the most reliable summer crops. Wind pollination works particularly well in the flat, open Midwest.

Springs warm fast, so sow early and cut often. The fall crop is usually the better one; shade cloth over late-summer sowings keeps the soil cooler and improves germination.

Cucumbers tend to perform well in Midwest summers, though bacterial wilt spread by cucumber beetles is a persistent issue. Row cover at transplanting and hand-picking beetles once flowers open can significantly reduce losses. Consistent watering during dry spells is critical to prevent bitterness.

Good conditions for delicata. The 80-day season fits well within the Midwest's frost-free window. Vine borer pressure varies by year; row cover through June minimizes risk.

Edamame generally does well in the Midwest's warm summers. Bean beetles can be a persistent pest in some areas; checking plants in early morning and hand-picking beetles before populations build tends to prevent serious damage.

The Midwest's hot July and August suit eggplant well, but a late frost or cool June can compress the season. Start seeds early and be patient with transplant timing.

Timing matters significantly in the Midwest — spring sowings may bolt if a late cold snap occurs, and fall sowings need to mature before hard freezes arrive. A midsummer sowing around late July tends to hit the sweet spot in most zones.

Fall is the primary escarole season in the Midwest. Direct sowings in late July or early August mature as the weather cools, and the plants tolerate light frosts well. Spring plantings may succeed in cooler years but are less predictable.

The Midwest's short spring can make timing tricky. Plant as early as the soil is workable — 4 to 6 weeks before last frost. In zones 5 and 6, the harvest window may be only 3 to 4 weeks before summer heat shuts the plant down. Earlier is almost always better.

Both spring and fall sowings are possible in parts of the Midwest, though fall plantings tend to be more forgiving. The rapid transition from cool to warm in late spring can catch a spring-sown crop before the bulbs have fully developed, while a late-summer sowing matures into the stable cool weather of autumn.

Cold, reliable winters make the Midwest well suited to hardneck garlic. German Extra Hardy and Chesnok Red overwinter with minimal losses under straw mulch; plant in late September to mid-October before the first hard freeze.

Beans generally do well across the Midwest, though timing the planting to avoid late spring cold snaps matters. Succession plantings every two weeks through early July tend to provide a steady supply of fresh beans into September.

Ground cherries generally do well in the Midwest's warm summers, and the sprawling plants benefit from the open space many Midwest gardens offer. Caging or staking at transplant time tends to improve yields and make harvesting less of a scavenger hunt.

The cold winters and fertile soils of the Midwest create ideal conditions for horseradish, and it tends to be vigorous and productive. The challenge is containment — the plant spreads readily in loose prairie loam and can become difficult to eradicate once established.

The Midwest's cold winters and variable rainfall suit sunchokes well. They are drought-tolerant enough to handle dry spells and cold-hardy enough to overwinter reliably in all Midwest zones. The primary management concern is preventing them from taking over more garden space than intended.

Kale handles Midwest winters reasonably well, especially in zone 6 and warmer, and fall plantings often produce until a hard freeze. Spring crops tend to do well until July heat arrives. Cabbage worms are the main pest; row cover at planting or early-season hand-picking usually controls them.

Early spring and fall crops both work well. The mid-season heat makes summer production impossible. In zone 5 and colder, fall sowing in August gives plants enough time before first frost.

Summers are usually warm enough to ripen a crop of red peppers if plants go out on time into warm soil. Black plastic at planting and stakes against summer storms both pay off. Pick red peppers promptly as they color; late-season rain can spread anthracnose on ripe fruit.

Sow on schedule; the fall window is short and hard freezes come early in the northern Midwest. Heavy clay soils favor the shorter Korean types over long daikon. Water seedlings daily during late-summer heat.

Grows well in Midwest summers once the soil is warm. Vine borers are common, and burying a few nodes on each vine gives backup roots if the base is attacked. Sturdy trellis anchors matter; summer storms can flatten a loaded vine.

A reliable fall crop across the Midwest. King Richard is a good choice for shorter-season northern gardens; American Flag and Giant Musselburgh work well in zones 5 and 6 where the season allows fuller development.

Lettuce performs well in the Midwest in spring and fall. The shift to warm nights in late May or June typically signals the end of the spring crop; resuming sowings in mid-August usually gives a productive fall harvest.

Lima beans generally perform well in the Midwest's warm summers, though northern areas may find the season too short for pole varieties. Bush types sown in early June after the soil has warmed tend to produce reliably in zones 6 and 7; farther north, choosing the earliest maturing varieties is essential.

Malabar spinach generally does well in Midwest summers once the soil warms, though waiting until early June to transplant is often necessary. The vine tends to grow vigorously through July and August, making it a reliable heat-season green.

Good early spring and fall crop. The wide temperature swings of Midwest springs can cause unpredictable bolting — succession sow frequently to keep fresh plantings coming.

Sow on schedule — the fall season is short and an early hard freeze can arrive soon after the first frost. Choose a variety around 55 days such as Haku or Bilko and keep seedlings well watered through late-summer heat.

Summer heat in the Midwest is ideal for New Zealand spinach, and it tends to be one of the more reliable hot-weather greens. The plants can handle the variable rainfall typical of the region, though consistent moisture during establishment helps.

Okra works well in the Midwest's hot July and August. In zones 5 and 6, use early varieties and sow after the soil has fully warmed. Cooler Augusts reduce production but don't usually eliminate it.

Long-day varieties perform well across the Midwest. Copra is a dependable storage choice for gardeners who want onions through winter. Start seeds 10 weeks before the last frost and expect to transplant around the time of that frost date.

Reliable cold winters in the Midwest mean parsnip flavor tends to be excellent by fall harvest. Plant in spring and expect peak flavor after the first sustained frosts in October. In zones 4 and 5, mulch heavily in November to keep the ground workable.

Peas generally perform well in the Midwest's cool springs. Sowing in late March or early April typically allows for a productive harvest in May and early June before the summer heat ends production. The fall crop is less reliable due to variable frost timing.

Southern parts of the Midwest — southern Missouri, southern Illinois, Kentucky — can grow peanuts if the frost-free season reaches 130 days and the summer is hot. Farther north, the season is too short and the crop becomes unreliable. Sandy river-bottom soils tend to give better results than heavy prairie loam.

Peppers perform reasonably well in the Midwest once summer heat arrives, though the season can be borderline for some longer-maturing varieties. Mulching heavily to maintain even soil moisture and using black plastic to warm the soil at planting time both tend to improve results.

Popcorn is well-suited to Midwest conditions, with ample heat and a long enough season for most varieties. The primary challenge is isolating popcorn from field corn, which is widely grown in the region — timing offsets are often the most practical solution for home gardeners.

Reliable potato production across the Midwest with proper variety selection. Japanese beetle larvae (grubs) can damage tubers in some areas. Rotate beds annually and choose a mix of early and mid-season varieties for an extended harvest window.

Pumpkins tend to perform well in the Midwest's warm summers. The main challenge is timing — planting too early into cold soil causes seed rot, but planting too late risks immature fruit at first frost. Waiting until the soil reaches sixty-five degrees consistently tends to produce better stands.

Radicchio does well in the Midwest's crisp autumns, where steady cooling and reliable frosts produce heads with good color and sweetness. The cut-and-resprout method works particularly well in zones 5 and 6 if mulched heavily before the first hard freeze.

Reliable spring production in the Midwest before heat arrives. Summer is too hot for most spring radish types; resume with fall sowings in late August. Daikon can be sown in early August for an October harvest.

Rhubarb thrives in the cold winters and warm summers of the Midwest. The plants handle both temperature extremes well, and established crowns can produce heavily for many years. Spring harvest typically begins in late April or early May.

Rutabagas perform reliably in the Midwest where fall temperatures drop decisively. Sow in July for October harvest. In zones 3 and 4, mulch the bed heavily in late October to extend the harvest window before the ground freezes solid.

Salsify generally does well in the Midwest, where the season is long enough for the crop to mature. The roots tend to develop good flavor when left in the ground through fall frosts. Heavy clay soils common in parts of the region may require deep amendment or raised beds.

Scallions can be sown very early in the Midwest — often by late March — and succession plantings through June tend to give a steady harvest. Onion thrips are occasionally a problem in hot, dry summers.

Reliable results in the Midwest from spring planting. Choose Conservor or Ambition for long storage, and cure bulbs indoors during the humid August and September weeks when outdoor curing risks mold.

Spinach generally does well in the Midwest in both spring and fall. The spring crop can bolt quickly if May turns warm; the fall crop sown in late August tends to be more forgiving and often produces sweeter leaves after a few light frosts.

The Midwest can grow sweet potatoes in zones 5 and warmer, but the season is tight. Use slips from an early variety, warm the soil before planting, and plan to dig in mid-fall.

Excellent spring and fall crop with good summer production. The heat tolerance is the key advantage here over spinach or lettuce. Leaf miner pressure tends to be moderate to high in wet Midwest summers.

Tatsoi does well as a fall crop in the Midwest, though hard freezes in November or December typically end the outdoor harvest in zones 5 and colder. Succession plantings in late August and early September can extend the window before frost.

Good tomatillo territory. Hot July and August suit fruit set, and the plants are more heat-tolerant than tomatoes at peak temperatures. Self-sowing can be a minor nuisance in subsequent years.

Tomatoes tend to perform well in the Midwest's warm summers, with sufficient heat to ripen most varieties. Consistent mulching and deep watering help manage the variable rainfall that can cause blossom end rot. Hornworms are a common pest; checking plants every few days in midsummer usually catches them before they do serious damage.

Fall is the better window for turnips in the Midwest, where spring can transition rapidly to summer heat. Sow in late July or August for harvest in October. Purple Top White Globe handles cold well and can be left in the ground until hard frost.

The Midwest's hot summers work well for watermelon if the season is long enough. In zones 4 and 5, start indoors and use soil warming to maximize the window.

Southern parts of the Midwest with reliably hot summers — zones seven and eight — tend to grow yardlong beans successfully. Farther north, the season may be too short or too cool for consistent production. A late planting after the soil warms thoroughly in June sometimes works better than an early sowing.

Zucchini generally does well in Midwest summers. Vine borers are common; row cover early in the season tends to prevent most infestations. Powdery mildew usually arrives in August but rarely stops production before frost.

Basil generally performs well in Midwest summers, though late spring cold snaps can set plants back. Succession plantings spaced a few weeks apart tend to give a steadier harvest than one large planting that may hit bad weather at a vulnerable stage.

Bay laurel must be grown as a container plant throughout the Midwest and brought indoors well before the first frost. The dry indoor air of heated Midwest homes in winter tends to suit bay better than humid climates, but consistent light from a south-facing window or supplemental grow lights is essential to prevent leaf drop.

Borage generally does well in Midwest summers, flowering from June until frost. The plant handles heat reasonably well if given adequate water during dry spells, though it may slow flowering during prolonged hot periods above 90 degrees.

Both spring and fall crops are possible in the Midwest. Spring-sown chamomile usually blooms well in May and early June; a late-summer sowing can extend the season into fall in areas where frost arrives late.

Both spring and fall crops are possible in the Midwest, though the fall sowing tends to give a longer harvest window. Spring-sown chervil often bolts by early June as temperatures rise; succession sowings every two weeks in April and May can extend the season.

One of the hardiest herbs for the Midwest. Emerges reliably even in zone 3 gardens. Divide every few years to maintain vigor. The spring flower display is a useful early-season pollinator source.

Cilantro does well in Midwest springs, though the transition to summer heat can be abrupt. Succession sowing every two weeks from early April through early May tends to extend the harvest. Fall sowings in late August or early September often produce well into October.

Well-suited to the Midwest growing season. Start direct sowing as early as the soil can be worked. Succession-plant through June; after that, summer heat pushes plants to seed quickly. Fall sowings in August can produce a second frond-harvest window.

French tarragon tends to do well in the Midwest, where summers are warm but not excessively hot. Division every three years is particularly important in the heavy clay soils common in parts of the region, where drainage can be a limiting factor.

Reliably hardy and productive; cold winters kill the tops but not the bulbs. Seedlings readily escape into lawns and borders, so deadhead after bloom. Divide every three years to keep cuttings thick.

Grows well once nights are warm, and tolerates short dry spells, though leaves get smaller without water. Perilla is a known pasture weed in the southern Midwest; if you live near livestock, do not let it set seed.

Hardy through zones 5–7 in raised beds with sharp drainage. The upper Midwest's cold, dry winters are often gentler on lavender than the wet winters of the Mid-Atlantic. Mulch with gravel after the first frost and avoid mulching with organic material that holds moisture.

Hardy throughout the region. Vigorous in zones 5–7. The freeze-thaw cycles of the upper Midwest rarely cause problems in well-drained soil. Divide overcrowded clumps every three to four years.

Container culture is necessary throughout the Midwest. The plant tends to enter dormancy earlier in cold-fall years; plan to move it indoors by late September. A cool basement or unheated garage that stays above freezing works well for winter storage.

Lemongrass grows vigorously in Midwest summers, but the season is relatively short. Transplanting after the soil is reliably warm — typically late May — and digging up a division in September before the first frost gives the plant time to produce well.

Lovage performs reliably in the Midwest, where cold winters pose no threat and the plant can live for decades. The main challenge is managing its size — a lovage plant in rich bottomland soil can easily exceed six feet and become a garden fixture for better or worse.

Hardy throughout the region. Mint handles cold winters without help and is usually among the first herbs to emerge in spring. The main management task is keeping it contained in open beds.

Hardy to zone 4a with good drainage. The main threat is freeze-thaw heaving in late winter; a thin layer of straw mulch helps hold the crown in place. Divide crowns every three years to keep plants vigorous.

Start indoors 10 weeks before the last frost. Parsley does well through the Midwest's spring and early summer; expect it to decline or bolt in July heat. A fall planting started in August can extend the season into October.

Treat as a container plant or annual in most of the Midwest. Hardy varieties like Arp may survive a zone 6 winter in a very protected spot, but expect loss in zones 5 and colder. Container plants overwinter well in a cold, bright garage or south-facing window.

Hardy and productive in zones 5–7. The main concern is wet soil in spring when the ground thaws. Raised beds pay off here. Expect slower growth early in the season — sage is slow to wake up after a cold winter.

Shiso tends to do well across the Midwest once warm weather arrives, and the plant tolerates both heat and occasional dry spells better than basil. Self-seeding can be prolific — gardeners who leave plants to flower often find themselves with a permanent shiso patch within two seasons.

Overwinters without protection in zones 4–7 in the Midwest. One of the earliest spring greens available. Mulch around the crown in zone 4 for a bit of extra protection. Bolts in the heat of July — cut stalks and expect a fall rebound when temperatures ease.

Warm Midwest summers generally support stevia, though the plant may struggle in regions with cool nights or a short frost-free period. Starting indoors well ahead of last frost and choosing a warm planting site can improve results. Flowering typically begins in late August.

Marjoram tends to do well in Midwest summers. The relatively dry air and warm days allow the plant to develop its full aromatic complexity. Starting seeds indoors in March or April for transplanting in mid- to late May is a common approach.

Hardy to zone 5 with good drainage. The bigger concern than cold is poorly drained flat ground that stays saturated in spring. Raised beds help significantly. Divide plants every two to three years to prevent the center from going woody.

The Midwest's climate generally suits apples well, with adequate chill hours and a long enough season for most varieties. Fire blight can be severe in warm springs, and Japanese beetles may damage foliage in midsummer.

Blackberries tend to do well in the Midwest's warm summers, though winter hardiness can be a limiting factor in the northern tier. Thornless varieties are often less cold-hardy than thorned types; in zone 5 and colder, wrapping canes or laying them down under mulch for winter may be necessary.

Northern highbush varieties work in zones 4 through 6. Soil pH in the Midwest often runs neutral to alkaline and may need significant sulfur application over several seasons. Raised beds filled with acidified growing medium can be a practical alternative in heavy clay or limestone-based soils.

Cherries tend to perform well in the Midwest, where the continental climate provides a reliable winter chill and a warm, relatively dry summer. Late spring frosts can occasionally damage blossoms, so site selection on a slope where cold air drains is helpful. Both sweet and sour varieties can succeed, though sour cherries are more forgiving of variable conditions.

Cold hardiness makes currants a good fit for the upper Midwest, where they can handle zone 3 winters without issue. Black currants are restricted in some Midwest states with significant white pine populations; red currants are usually permitted and perform well.

Elderberry is well-suited to the Midwest, where it grows wild along ditches and field edges. The cold hardiness is excellent, and the shrubs tend to leaf out late enough to avoid late spring frosts. Bird pressure at harvest is often high.

Figs are marginal in most of the Midwest due to cold winters. Zone 7 areas along the Ohio River may succeed with Chicago Hardy and heavy winter protection, but the crop is uncertain. Container culture with winter storage in a garage is a more reliable strategy for zone 6 and colder.

The cold winters and moderate summers of the Upper Midwest create good growing conditions for gooseberries. Sawfly can be a recurring pest; checking plants in late spring and early summer usually catches infestations before they defoliate the bush. Mildew-resistant varieties tend to perform reliably.

Cold-hardy American varieties and some French-American hybrids generally do well in the Midwest. Black rot and Japanese beetles are the main challenges. Sites with good air drainage to avoid late spring frosts tend to produce more reliable crops.

Mulberries generally do well in Midwest conditions, tolerating both the cold winters and hot summers. Established trees tend to fruit reliably without much intervention. The main challenge is often managing the volume of fruit and the cleanup under standard-sized trees.

Pawpaws are native across much of the Midwest and generally thrive in the region's climate. The main limitation is pollination; flies and beetles may be less abundant in open suburban yards than in forest edges, making hand-pollination a common practice.

Peaches can produce well in the Midwest when late frosts don't interfere, but the variability of spring weather makes cropping inconsistent. Borers are common, and checking the trunk base for gummy sap in late summer can catch infestations before they girdle the tree.

Pears tend to do well in the Midwest, with adequate chill hours and moderate disease pressure compared to the Southeast. Fire blight is still a concern in wet springs, and cold winters at the northern edge of the range can damage young trees if they aren't fully hardened off.

Plums generally perform well in Midwest gardens, though cold winters at the northern edge of the region can kill flower buds on Japanese varieties. European types like Stanley are more reliably cold-hardy and tend to crop more consistently in zones 4 and 5.

Good raspberry territory in the northern tier — Minnesota, Wisconsin, Michigan. Cold winters keep disease pressure in check and favor cold-hardy varieties. Fall-bearing varieties like Heritage and Caroline reliably produce in the Midwest's warm late summers. In the warmer southern Midwest, disease pressure increases.

Serviceberry is well-suited to the Midwest, tolerating cold winters and variable spring weather. It tends to bloom early enough that late frosts occasionally damage flowers, reducing the crop, but it recovers and fruits reliably in most years.

Reliable June-bearing varieties like Honeoye and Earliglow perform well in the upper Midwest. Winter protection with straw mulch is important in zones 4 and 5. Late spring frosts can damage open flowers — have row cover on hand to protect plants during flowering.

Bee balm generally thrives in Midwest gardens with adequate moisture. Mildew can be an issue in humid summers, but resistant cultivars usually stay presentable. The plant's spreading habit is more pronounced in rich, moist soil — division every 2–3 years keeps it in bounds.

Butterfly weed is native across much of the Midwest and generally thrives in the region's prairies and disturbed ground. The main challenge is heavy clay in some areas, which can cause crown rot if drainage is poor. Planting in raised beds or working in coarse sand tends to solve the problem.

Performs well in the Midwest's cool springs. Direct sow around your last frost date or a couple of weeks before. It blooms through May and June before shutting down in July heat. Cutting back in midsummer sometimes produces a fall rebloom in zones 5 and 6.

Well-suited to the Midwest's hot summers. Direct sow at last frost, thin to proper spacing, and they'll bloom through August. Afternoon thunderstorms can flatten tall varieties — stake early or stick to compact types like Sonata.

Phlox is well-adapted to the Midwest, thriving in the warm summers and cold winters. Mildew pressure is moderate; resistant varieties and regular thinning usually keep plants presentable through most of the bloom season.

Northern parts of the Midwest tend to have better success with lupines than southern areas, where summer heat can be too intense. Providing consistent moisture and afternoon shade in zones 6 and 7 may extend the plant's productive years.

Straightforward performers in the Midwest's warm summers. Direct sow after last frost for a late-summer bloom, or transplant 6-week-old starts for earlier flowers. Generally low-maintenance once established.

Morning glories perform reliably across the Midwest, with vigorous growth and abundant bloom through the summer. Japanese beetles can occasionally defoliate vines in areas where beetle pressure is high, but the plants usually recover and continue flowering.

Solid summer annual for the Midwest. Direct sow at last frost when the soil is warming, and they'll bloom from midsummer through first frost. The compact Jewel Mix handles heat and thunderstorms reasonably well.

Peonies are exceptionally well-suited to the Midwest, where cold winters and warm summers create ideal conditions. The plants tend to be vigorous and long-lived, and bloom is reliable across most of the region.

The Midwest's climate closely matches purple coneflower's native prairie habitat, and the plant generally thrives with minimal care. Established plants handle drought, cold, and wind without complaint. Japanese beetles may be a problem in July; hand-picking is effective.

Both spring and fall flushes are possible in much of the Midwest. An early indoor start and transplanting in mid-April usually produces strong spring bloom; cutting plants back in midsummer and waiting for cooler September weather can bring a second crop of flowers.

Sunflowers are native to parts of the Midwest and tend to perform exceptionally well — they handle the summer heat, tolerate variable rainfall, and the tall varieties can reach their full genetic height. Wildlife pressure on seed heads can be significant in rural areas; covering heads intended for harvest is nearly essential.

Alyssum generally does well in Midwest gardens, with a long spring bloom period and a reliable fall rebloom if cut back in midsummer. Plants may self-sow aggressively in some areas, returning on their own the following spring along bed edges and pathways.

Sweet peas tend to do well in the Midwest if sown as soon as the ground can be worked in March. The season usually ends in July when temperatures climb, but the spring bloom period can be prolific if the plants are kept well-watered and deadheaded.

Coreopsis thrives in the Midwest's sunny summers and tolerates the variable rainfall patterns well once established. Japanese beetles occasionally chew the flowers in midsummer but rarely do serious damage. The plant's drought tolerance makes it a reliable choice for gardens that see dry spells in July and August.

Reliable producers in the Midwest's warm summers. Direct sow after last frost when soil has warmed, or start indoors 4 weeks before. Heat and sun are rarely limiting factors. Thunderstorms can flatten tall varieties — stake them loosely or choose Oklahoma series, which has stiffer stems.

Buckwheat is widely used in the Midwest as a fast summer cover between cash crops or as a smother crop ahead of fall vegetables. The warm, reliable summers and ample rainfall tend to produce vigorous stands with good weed suppression.

Crimson clover can overwinter in the southern Midwest (zone 6 and warmer), but winterkill becomes more common farther north. In zones 4 and 5, spring sowing as a quick summer cover is the more reliable strategy, though nitrogen fixation is lower than with a full overwinter cycle.

Both spring and fall sowing are possible in much of the Midwest, though winter survival of fall-sown stands is less reliable north of zone 6. Spring-sown field peas generally establish quickly in the cool, moist conditions of early spring and can be terminated before the main planting season.

The Midwest's cold winters suit hairy vetch, and it is commonly grown in rotation with corn and soybeans. Stands typically establish well in September and overwinter reliably. Spring termination at full bloom in May provides nitrogen that becomes available as summer crops begin their heavy-feeding period.

The upper Midwest is ideal oat cover-crop territory. Late-August or early-September sowings establish quickly, produce substantial biomass, and reliably winter-kill by December. Mixing oats with field peas is a common strategy to add nitrogen fixation.

Tillage radish performs well in the Midwest's cold winters — winter-kill is reliable, and the long fall season in zones 5 and 6 gives the crop time to develop substantial roots. Compacted soils common in no-till corn and soybean systems respond noticeably to consecutive years of use.

White clover performs well across most of the Midwest, with reliable winter survival and good persistence in orchard alleys and pathways. Spring sowing four to six weeks before the last frost usually allows establishment before summer heat, though volunteer weeds can be aggressive during the slow early growth phase.

Winter rye is a reliable cover crop across the Midwest, handling the variable winters and establishing well in fall. Sowing in late September after harvest of summer crops is common; termination in May allows planting warm-season vegetables after the allelopathic period.
