Ohio’s February frosts make it wise to start slow-growing vegetables like cauliflower and artichokes indoors for a later transplant. Knowing the best vegetables to plant in february in ohio can turn a cold month into the start of a productive garden. This guide covers what to sow indoors and what can brave the chilly soil.
February in Ohio means snow, ice, and short days. But inside your home, you can get a head start on spring. Many vegetables need a long growing season, so starting them now ensures they mature before fall frosts return.
Best Vegetables To Plant In February In Ohio
Let’s break down the top choices for February planting. These vegetables either thrive when started indoors or can handle a cold frame or unheated greenhouse. The key is to match each plant’s needs with Ohio’s unpredictable late-winter weather.
Indoor Seed Starting Favorites
Starting seeds indoors gives you control over temperature and light. Here are the vegetables that benefit most from a February start in Ohio.
Cauliflower
Cauliflower is a cool-season crop that hates heat. By starting seeds indoors in February, you can transplant them in early April. This lets them mature before summer heat sets in. Use seed-starting mix and keep the soil at 65-70°F. Transplant after the last frost, usualy around mid-April in southern Ohio.
Artichokes
Artichokes need a long growing season, often 100-150 days. Starting them in February gives them time to produce buds before fall. They are perennials in warmer zones, but in Ohio treat them as annuals. Start seeds in deep pots because they have a taproot. Keep them under grow lights for 14-16 hours a day.
Broccoli
Broccoli is another cool-season vegetable that does well with an early start. Sow seeds indoors 6-8 weeks before your last frost date. For most of Ohio, that means late February. Use a sterile seed-starting mix and keep the soil moist but not soggy. Harden off seedlings before transplanting in March or April.
Cabbage
Cabbage can handle light frosts, so starting it indoors in February lets you transplant it early. Choose early-maturing varieties like ‘Early Jersey Wakefield’ or ‘Golden Acre’. Sow seeds 1/4 inch deep in trays. Keep them in a bright window or under lights. Transplant when seedlings have 4-5 true leaves.
Kale
Kale is incredibly hardy and can be planted outdoors in late March if started indoors in February. It actually tastes sweeter after a frost. Start seeds in small pots or cell trays. Keep the soil temperature around 60-70°F. Kale germinates quickly, often in 5-7 days.
Lettuce
Lettuce is a cool-season crop that can be started indoors in February for early spring harvests. Use loose-leaf varieties like ‘Black Seeded Simpson’ or ‘Red Sails’. Sow seeds shallowly, just covering them with soil. Keep the soil cool, around 60°F. Transplant outdoors under row covers in March.
Spinach
Spinach can be started indoors in February and transplanted outdoors in early spring. It prefers cool weather and can handle light frosts. Sow seeds 1/2 inch deep in deep containers because spinach has a long taproot. Keep the soil moist and provide bright light. Harvest baby leaves in 30-40 days.
Cold-Hardy Direct Sow Options
Some vegetables can be sown directly into the ground in February if you use protection. Ohio’s soil is often frozen or too wet, but with a cold frame or row covers, you can get a head start.
Peas
Peas are the most cold-hardy vegetable you can direct sow in February. They germinate in soil as cold as 40°F. Choose snow peas or shelling peas like ‘Sugar Snap’ or ‘Wando’. Plant them 1 inch deep and 2 inches apart. Use a cold frame if the ground is frozen. Peas will germinate slowly but will be ready by late spring.
Radishes
Radishes grow fast and can be sown in late February if the soil is workable. They tolerate light frosts and mature in 25-30 days. Sow seeds 1/2 inch deep in rows. Thin seedlings to 2 inches apart. Use row covers if a hard freeze is forecasted.
Carrots
Carrots can be sown in February in a cold frame or under row covers. They need loose, well-draining soil free of rocks. Sow seeds 1/4 inch deep and keep the soil moist. Carrots germinate slowly, taking 14-21 days. Choose short varieties like ‘Parisian’ or ‘Nantes’ for quicker maturity.
Turnips
Turnips are another cold-hardy root vegetable. Sow seeds directly in late February if the soil is thawed. Plant 1/2 inch deep in rows. Thin to 4 inches apart. Both the roots and greens are edible. They mature in 40-50 days.
Onions
Onions can be started from seed indoors in February or planted as sets outdoors. Sets are small bulbs that handle cold soil. Plant sets 1 inch deep and 4 inches apart. For seeds, start indoors 8-10 weeks before transplanting. Onions need long days to bulb, so early start is crucial.
Herbs To Start In February
Herbs are great companions for vegetables. Starting them indoors in February gives them time to grow before transplanting.
Parsley
Parsley seeds germinate slowly, so starting in February is ideal. Soak seeds overnight to speed germination. Sow 1/4 inch deep in pots. Keep soil moist and warm. Transplant outdoors after the last frost.
Cilantro
Cilantro prefers cool weather and can be started indoors in February. Sow seeds 1/4 inch deep. It germinates in 7-10 days. Transplant outdoors in early spring. Cilantro bolts quickly in heat, so early planting helps.
Chives
Chives are perennial and can be started indoors in February. Sow seeds 1/4 inch deep. They germinate in 10-14 days. Transplant outdoors in spring. Chives come back year after year.
Step-By-Step Indoor Seed Starting Guide
Follow these steps to successfully start seeds indoors in February for Ohio gardens.
- Gather supplies: You need seed-starting mix, containers with drainage, grow lights or a bright window, and a heat mat for some crops.
- Moisten the mix: Pre-moisten the seed-starting mix before filling containers. It should be damp but not wet.
- Sow seeds: Follow the depth instructions on the seed packet. General rule: plant seeds 2-3 times their diameter deep.
- Label everything: Use plant markers or popsicle sticks with the variety and date. It’s easy to forget what you planted.
- Provide warmth: Most vegetables germinate best at 65-75°F. Use a heat mat for crops like peppers and eggplant.
- Give light: Once seeds sprout, provide 14-16 hours of bright light daily. Place lights 2-3 inches above seedlings.
- Water carefully: Keep the soil moist but not waterlogged. Use a spray bottle or bottom watering to avoid disturbing seeds.
- Thin seedlings: When seedlings have two sets of true leaves, thin to one per cell or pot. This prevents overcrowding.
- Harden off: A week before transplanting, gradually expose seedlings to outdoor conditions. Start with a few hours of shade, then increase time and sunlight.
Ohio Specific Considerations For February Planting
Ohio has diverse climates. Northern Ohio near Lake Erie has colder winters and later springs. Southern Ohio near the Ohio River is slightly warmer. Check your USDA hardiness zone—most of Ohio is zone 5b to 6a. Your last frost date ranges from April 15 in the south to May 10 in the north.
Use a cold frame or row covers to protect early transplants. These structures can raise soil temperature by 5-10°F. They also shield plants from wind and frost. You can buy them or make a simple one from PVC pipes and clear plastic.
Soil preparation is key. In February, the ground is often frozen or too wet to work. If you plan to direct sow, prepare your beds in the fall. Add compost and cover with mulch. In spring, just pull back the mulch and sow seeds.
Consider using raised beds. They warm up faster than ground soil in spring. Raised beds also improve drainage, which is important in Ohio’s clay-heavy soil. Fill them with a mix of topsoil, compost, and perlite.
Common Mistakes To Avoid
Here are mistakes Ohio gardeners make when planting in February.
- Starting too many seeds: It’s tempting to start everything, but you only have so much space. Focus on slow-growing crops like cauliflower and artichokes.
- Overwatering: Seedlings are prone to damping off if soil is too wet. Water only when the top inch of soil feels dry.
- Not enough light: Ohio’s February days are short and cloudy. Without grow lights, seedlings become leggy. Use full-spectrum LED lights.
- Planting outdoors too early: Even cold-hardy crops can be killed by a hard freeze. Always check the 10-day forecast before transplanting.
- Ignoring hardening off: Sudden exposure to sun and wind can shock seedlings. Harden them off gradually over a week.
Tools And Supplies You’ll Need
To start seeds indoors in February, gather these items.
