You don’t have to give up fresh greens just because winter is coming. Imagine having a homegrown salad for Thanksgiving or Christmas. It’s possible if you grow veggies in a cold frame.
Cold frames come ready-made or in easy to assemble DIY kits. They require little care and provide fresh vegetables in cooler seasons. The key is to pay attention to the temperature.
A cold frame protects plants from ice and cold winds. Lettuce, cabbage, cauliflower, spinach and radishes can grow through winter and seeds can be started earlier in the spring.
Grow Fresh Veggies In Winter with a Cold Frame:
- Select a sunny, south-facing spot.
- If you haven’t done so, perform a soil test to ensure plants get the nutrients they need.
- Remove weeds, large rocks and any roots.
- Prepare the soil to a depth of 12”-18”.
- Rake in 2” of compost and any amendments indicated by your soil test.
- Rake the bed level.
- Cover with a cold frame with a translucent top.
- Sow seeds according to package directions or plant seedlings.
- Pile loose soil or mulch around the outside base of the frame to block out cold.
- Close only when temperatures are expected to drop below 25 degrees. Keep top propped 6” open when above 40 degrees and when the over 50 degrees, remove the lid.
- Check cold frame once a week, watering as needed to keep soil lightly moist.
