Best Vegetables to Grow in Missouri

Peas are the first seeds in the ground in Missouri, going out as early as late February or early March — 4 to 6 weeks before last frost. They thrive in the cool, moist conditions of early spring and deteriorate quickly once summer heat hits, so early planting is essential. Direct sow 'Sugar Snap' or 'Oregon Sugar Pod' 1 inch deep as soon as soil can be worked; they'll be done before Memorial Day heat sets in.

Broccoli performs best in Missouri as a fall crop, started from transplants in late July for harvest in October and November. Fall heads are larger, tighter, and sweeter than spring-grown ones, and the crop handles light frost without damage. Set transplants 18 inches apart and side-dress with nitrogen at transplant; loose, open heads in spring are a sign of heat stress, not a variety problem.

Cabbage handles Missouri's spring frosts well and can be transplanted outdoors 3 to 4 weeks before last frost, but the fall crop excels here — cool nights intensify sweetness and reduce cracking risk. Start fall transplants indoors in mid-July and set out in late August; varieties like 'Stonehead' and 'Deadon' are reliable for Missouri's fall conditions. Consistent soil moisture is critical to prevent splitting.

Cauliflower is the most temperature-sensitive brassica and requires careful timing in Missouri — it needs a narrow window of cool but not freezing temperatures to form tight curds. Fall planting (transplants out in mid-August) is far more reliable than spring, as summer heat makes spring cauliflower head prematurely or not at all. Blanch white varieties by tying outer leaves over the developing curd when it reaches golf-ball size.

Kale is one of Missouri's most forgiving crops, tolerating both late spring frosts and early fall freezes while actually improving in flavor after cold exposure. Direct sow or transplant in March for spring, or direct sow in August for fall; fall-grown kale left in the garden will often survive Missouri winters and resume growth in February. 'Red Russian' and 'Lacinato' are particularly cold-hardy and perform well across the state.

Lettuce bolts quickly in Missouri's summer heat, so timing is everything — direct sow outdoors from mid-March and plan to finish harvesting by late May in most of the state. The fall window is equally productive: sow again in August and September for harvest through October, and use row cover to push harvest into November. Loose-leaf types like 'Black Seeded Simpson' are faster and more heat-tolerant than head types if you're racing the calendar.

Spinach is the earliest-starting and most cold-hardy leafy green for Missouri, germinating in soil as cold as 35°F and surviving hard freezes under row cover. Sow directly from late February and again in September for fall; the fall crop often overwinters under straw mulch and produces again in early spring. Bolt-resistant varieties like 'Bloomsdale Long Standing' or 'Tyee' buy extra time before the heat triggers seed stalks.

Swiss chard uniquely bridges Missouri's cool and warm seasons — it tolerates both spring frosts and summer heat better than almost any other leafy green in the state, making it one of the longest-producing vegetables you can grow here. Start transplants or direct sow in April and harvest outer leaves continuously from June through October. 'Bright Lights' handles Missouri's humid summers without wilting or bolting, and the plants will rebound vigorously after fall temperatures drop.

Carrots need consistent soil moisture and loose, deep, rock-free soil to form straight roots — amending Missouri's clay soils with compost is non-negotiable for good results. Direct sow in March and April for early summer harvest, or sow in late July to early August for a sweeter fall crop; carrots left in the ground after frost convert starches to sugar and can be harvested through November. 'Danvers 126' and 'Chantenay' perform well in heavier soils where longer varieties fork or stunt.

Beets are a dual-purpose crop in Missouri — harvest greens early and roots once they reach 1.5 to 3 inches in diameter, which prevents woodiness in the state's warmer conditions. Direct sow 4 to 6 weeks before last frost in spring, or sow in August for a fall crop; fall beets are consistently sweeter. Soak seeds for 12 hours before planting to improve germination, and thin seedlings to 3 inches apart — crowded beets produce no usable roots.

Radishes are the fastest crop in Missouri and the easiest way to use gaps between slower-maturing vegetables in spring and fall. Direct sow every 2 weeks from March through May and again from August through October for continuous harvests; summer heat renders radishes hollow and pithy, so skip the season entirely. 'Cherry Belle' matures in 22 days and is ideal for Missouri's compressed spring windows before heat sets in.

Onions require the longest cool-season commitment in Missouri, so starting from transplants or sets in mid-March gives them the head start they need to size up before summer heat causes premature bulbing. Plant sets 1 inch deep and 4 inches apart; intermediate-day varieties like 'Candy' or 'Patterson' are best suited to Missouri's day length and climate. Tops will fall over naturally in late June or July — that's your harvest signal, and prompt curing in a dry, ventilated space is critical in humid Missouri summers.

Garlic is planted in October in Missouri — just after the first frosts — and overwinters in the ground for harvest the following June or early July, making it one of the highest-return crops per square foot in the state. Plant individual cloves 2 inches deep and 6 inches apart, mulch heavily with straw after the ground freezes, and remove scapes (the curling flower stalks) in June to redirect energy into the bulb. Hardneck varieties like 'Chesnok Red' and 'Music' overwinter reliably in Zone 6 and produce large, flavorful bulbs.

June-bearing strawberries planted in Missouri in early spring (March to early April) establish through the first season and deliver a concentrated, high-yield harvest the following May and June — pinch all flowers the first year to build plant vigor. The state's cold winters stratify crowns naturally, which is essential for strong spring flowering. 'Earliglow' and 'Allstar' are well-adapted to Missouri conditions, and mulching with straw in late November protects crowns from freeze-thaw heaving without smothering the plants.
