However, note that plants will dry out less quickly indoors and will also grow more slowly, needing less fertilizer. To make watering easier, it is wise to set the pots in large trays with an inch or two of decorative stones. Not only will this prevent having to move the plants in order to water them, it will also provide humidity, which is a major requirement, especially during winter when the house is warm and dry. A sunny window, preferably south-facing, is a must for indoor vegetable growing. Insufficient light will result in tall, spindly plants and failure to flower and set fruit.
Herbs are a first choice for many indoor gardeners.
Many are less demanding than vegetable plants, and cooks find it pleasant to be able to snip off a few sprigs of fresh parsley or chop some chives from the windowsill herb garden. Chives grow like small onions with leaves about six inches tall. These plants prefer cool conditions with good light, but will grow quite well on a windowsill in the kitchen. One or two pots of chives will provide leaves for seasoning salads and soups. Plant seeds or small bulbs in a six-inch pot.
