Check their moisture daily. Let your plants dry out somewhat between waterings, but plants in small pots may still need water every day. Slow-acting organic fertilizers are a good choice for these windowsill gardens. Too much strong fertilizer can burn tender seedlings and encourages fast growth that then attracts insects and produces less flavor. Depending on what you choose to grow, your farm can be started from seed or from transplants.
Most greens are a snap to start from seeds, germinating in a few days and growing quickly.
All leaf lettuce varieties do well on windowsills, and while you may not grow enough to supply salads regularly for a family, even a few leaves add a wonderful fresh taste. Try growing some of the more unusual and expensive greens so popular now. Arugula, cress, salad burnet, escarole and mache are only a few of the varieties available as seed that will sprout and spice up a salad. Not only do these add zest to a salad, they also add lots of nutrients. When you re ready to harvest, don t pull an entire plant.
