Do you have a sunny window in your home? Why not sow some spinach or a leafy variety of lettuce in a planter?
It is very easy to grow spinach and leaf lettuce all winter long this way. As you’re plants produce, you break off or cut the outside leaves. The plant will continue to produce for a long time. As the plant begins to slow down, sow new seeds in another planter.
By doing this, you can enjoy fresh leafy greens long after the winter snows begin to fall.
