What to Grow in February: Seeds to Start Now

February marks a significant transition in the gardening year, bridging winter dormancy with the promise of spring growth. This month is the quiet preparation period for the activity that follows. Gardeners must use this time for deliberate planning and initiating crops that require a long head start. This early start ensures plants develop robust root systems and foliage before the warmer growing season begins.

Understanding Your Planting Zone

Successful February planting is dependent on geographical location and local climate conditions. The USDA Hardiness Zone map provides a general framework, classifying regions based on average minimum winter temperatures. This system helps determine which perennial plants can survive in a specific area, but it offers less guidance for starting annual vegetables. For timing annual seed starts, the more relevant metric is the “Last Frost Date” (LFD) for a specific region.

Knowing the average LFD dictates the safe transplanting window for tender seedlings. Gardeners in warmer zones, typically those with an LFD in late February or early March, can begin direct sowing many crops immediately. In contrast, those in colder zones, with an LFD potentially in late April or May, must focus primarily on starting seeds indoors to maximize the short outdoor growing season. All planting actions this month must be calculated backward from the expected last day of freezing temperatures.

Starting Seeds Indoors Now

February is the time to start seeds for warm-weather crops that require a lengthy juvenile stage. These plants, often demanding 8 to 12 weeks of indoor growth, would not yield a timely harvest if sown later. Peppers and eggplants are prime examples, as their seeds often exhibit slower germination rates and the seedlings grow slowly. Starting these now allows them to reach a substantial size, capable of immediate flower production once transplanted outdoors after the frost risk has passed.

Tomatoes, particularly late-maturing, indeterminate varieties, benefit from a February start. Varieties that take 80 or more days to reach maturity need this extended period under controlled conditions to ensure fruit set during summer heat. Seeds should be sown roughly a quarter-inch deep in a sterile seed-starting mix to minimize the risk of damping-off disease. Providing bottom heat, often through warming mats, can hasten the germination process for these heat-loving Solanaceae.

Once seedlings emerge, they require intense light to prevent stretching into weak, pale stems, a condition known as etiolation. A dedicated grow light system placed a few inches above the young plants is necessary, providing 14 to 16 hours of illumination daily. Long-season perennial herbs, such as rosemary, which can take several weeks to germinate, should also be initiated now. Basil, though faster-growing, benefits from an early start to provide leaves throughout the summer.

Direct Sowing in Cold Soil

For gardeners where the soil is not completely frozen, late February permits the direct sowing of cold-tolerant crops outdoors. These seeds are adapted to “vernalization,” where exposure to cold temperatures triggers the necessary physiological changes for germination and growth. Peas, both shelling and snap varieties, can be planted as soon as the soil is workable, ideally when the temperature is above 40 degrees Fahrenheit. The planting depth should be about one inch to protect them from superficial freezes.

Hardy leafy greens like spinach and arugula are excellent choices for February direct sowing. These crops germinate well in cooler soil, sometimes as low as 35 degrees Fahrenheit, and can withstand light frosts once they have emerged. Radishes, which mature rapidly, can also be sown now for the earliest spring harvest, as they prefer cooler conditions for root development and tend to bolt, or flower prematurely, in summer heat. These early plantings can be staggered every two weeks to ensure a continuous supply.

Root vegetables, including carrots and beets, can be sown directly, provided the soil is loose and does not present large, frozen clods. Carrots, in particular, require well-aerated soil for straight root formation. To extend the planting window and protect emerging seedlings from harsh temperature swings, gardeners can utilize physical barriers. Row covers (light sheets of fabric) or cold frames (box-like structures with clear lids) help elevate the soil temperature and shield young plants from wind and heavy frost.

February Garden Maintenance and Preparation

Beyond sowing seeds, February is an opportunity to complete maintenance that streamlines the later growing season. Pruning dormant deciduous fruit trees and shrubs, such as apples, pears, and raspberries, should be finalized before the buds begin to swell. Removing dead or diseased wood encourages vigorous new growth and improves air circulation, which helps prevent fungal issues. Sharpening and cleaning garden tools is a practical task for days when the weather is inclement.

This period is ideal for planning the garden layout and organizing crop rotations to prevent the buildup of soil-borne pests and diseases. Sending soil samples to a local extension office for testing provides valuable data on pH and nutrient levels, allowing for amendments before spring planting. If available locally, bare-root stock of roses, strawberries, and other berry bushes should be planted now while dormant, giving their root systems time to establish.
