How to Grow an Indoor Herb Garden

Overview

Many types of herbs can be grown in an indoor herb garden, and culinary herbs like basil, oregano, thyme and parsley are among the most popular. When grown indoors, herbs will flourish year-round, providing you with fresh herbs for cooking in any season. Just like in outdoor gardens, the secret to growing an indoor herb garden is providing the plants with enough sunlight and a good, well-drained soil.

Step 1

Select a location that has a southern or western facing window and set up the herb garden as close to the window as possible for maximum light exposure. Planting in small pots that will sit directly on the windowsill is an ideal way to get full sunlight.

Step 2

Mix two parts of potting soil to one part sand or perlite and a teaspoon of lime for each 5 inches of the pot's diameter. Fill the pot with this soil mixture over 1 inch of gravel at the bottom to help with drainage.

Step 3

Plant each herb in a separate pot according to the directions on the seed packet. Place only the number of seeds suggested on the packet in the soil, and cover loosely.

Step 4

Move perennial herbs, such as marjoram, sage and oregano, outdoors during the summer months. Leave the herbs in their pots, but plant them in soil down to the rim of the pot.

Step 5

Do not overwater herbs. The soil should be kept barely moist at all times, but never saturated.

Step 6

Group herbs together according to their watering needs to make it easier to water them properly and ensure that they do not get overwatered. Newly growing herbs need more water than established herb plants. Herbs planted in hanging baskets or clay pots require more water than those in plastic planters.

Step 7

Supplement the shortened daylight hours during winter months with small grow lamps. Leave herbs in the lights only long enough to make up for the lesser amount of sunlight coming in naturally during winter months, around six or seven hours a day.

Step 8

Repot herbs once every year. Remove them from the pot and throw out any soil that is not directly attached to the rooting system. Return the herbs to the pot. Add fresh soil around the base.
