Herb Gardening Indoors
Gardening Indoors can be done easily if you have the proper conditions in your home. The key to success is having enough light for the plants to do well. West and South facing windows provide the most light. If the herbs are not getting enough light they will just stop growing and may eventually have insects or diseases attack them.
Another problem with growing indoors is humidity or lack of it. Our heating systems are primarily dry heat and the plants can suffer from lack of moisture in their leaves even though they are watered. This can be corrected by misting or washing your plant's leaves every 2 weeks.
Most Herbs Prefer Temperatures from 65-80 Degrees
Most herbs prefer temperatures from 65-80 degrees and watering when the soil is dry to the touch. Never let your plants sit in a tray of water as their roots will drown. Also, make sure that the pots you use are large enough for the plant to grow for up to 6 months. Pots that are 8" in diameter are best.
Moving Your Plants Outdoors
It is generally best to move your plants outdoors as soon as it is warm and they will really appreciate an afternoon of sunshine on warm days, just remember to bring them back indoors during the cool nights.
Preparing Perennial Herbs for Winter
In very mild winter areas nothing needs to be done except a light pruning, cutting off about a third of the plant to trim up and encourage a nice form for spring.
Cold Winter Areas
In cold winter areas, the annual herbs will die as soon as the first frost hits them. The perennials can last if they are hardy to your zone. Rosemary, Sage, Lavender and others need to be pruned (about a third) and then mulched with anything that will protect them from the cold and wet. Cover their stems and root systems with hay or leaves or pine straw to keep the freezing wind from doing damage.
Taking Cuttings of Your Plants
You can also take cuttings of your plants and root them indoors keeping them moist and in a humid environment until they are rooted and then pot them. Another option is to dig up your herbs and put them in large pots to bring indoors for the winter.
