February is an excellent time to start planning your vegetable garden, especially in Zone 6 where the growing season begins to kick off as winter starts to recede. Among the most rewarding crops to plant early are kale and spinach, both of which thrive when started indoors or in protected outdoor spaces during this month.
Why Choose Kale and Spinach in February?
Kale and spinach are cold-hardy greens that can tolerate the lower temperatures typical of early spring in Zone 6. Starting their seeds in February gives these nutritious vegetables a head start, allowing for an earlier harvest and a continuous supply of fresh greens during the spring months.
Benefits of Early Planting
- Extended harvest period
- Stronger plants due to longer growing time
- Better flavor as greens mature slowly in cooler weather
- Reduced risk of pests and diseases common later in the season
How to Start Kale and Spinach Seeds
Starting seeds indoors or in a protected outdoor bed is ideal in February. Use seed trays or pots with quality seed-starting soil. Keep the soil moist and place the containers in a location with bright, indirect sunlight or under grow lights.
Indoor Seed Starting
Indoor starting allows for better control over temperature and moisture. Maintain a temperature of around 65-75°F (18-24°C). Once seedlings develop their first true leaves, they can be transplanted outdoors after the danger of hard frost has passed.
Outdoor Direct Sowing
If the weather permits, you can sow seeds directly into prepared garden beds. Use row covers or cold frames to protect young plants from frost. Sow kale and spinach seeds about ½ inch deep and space them according to the variety’s recommendations.
Caring for Your Early Greens
Ensure consistent moisture and avoid letting the soil dry out. Mulching around the plants can help retain soil moisture and regulate temperature. Keep an eye out for pests such as aphids and caterpillars, which can sometimes appear early in the season.
Fertilizing Tips
Use a balanced, organic fertilizer to support healthy growth. Avoid excessive nitrogen, which can make the plants lush but susceptible to cold damage. Incorporate compost into the soil for added nutrients.
Harvesting and Using Your Greens
Both kale and spinach can be harvested as baby greens or left to mature fully. For kale, pick the outer leaves first, allowing the center to continue growing. Spinach can be harvested by cutting the whole plant or individual leaves.
Enjoy your fresh greens in salads, smoothies, stir-fries, or as a cooked side dish. Their high nutritional value makes them an excellent choice for boosting health during the colder months.
