Even if you have nothing but a table with a lamp on it, you can grow lettuce for your salads and sandwiches.
This time of year, I'm all about growing things in the garden, but most of it is daydreaming right now. Instead of planting things in the snow, I plant them for the windowsills. Lettuce and radishes are easy to grow indoors, so I have to get the jump on the season.
Really, though, it's easy to grow those things year 'round indoors, so why pay between one and two dollars for a head of lettuce? Or almost as much for a small bunch of radishes? Why not have your salad and eat it, too??
A pot of eight inches or deeper, a few seeds and some water is all it takes. Both radishes and lettuce like cooler temperatures so a windowsill is ideal. Don't overwater, but don't let them dry out.
Use good soil. Potting soil is okay to start them, but you'll need to supplement with fertilizer or add compost to begin with. Fertilize the plants every month or so.
Harvest lettuce when the leaves are at least 4 inches tall. Cut off a few and let the plant grow again - that's why you need more than one plant.
Radishes are ready when they're as big as you want them.
If you want to save seeds from your lettuce and radishes, you'll need to set them outdoors when the weather settles. They'll be ready to go to seed in a couple of months, so plan accordingly.
