Fresh herbs can be grown indoors. A bright south, west,or east facing window, will provide enough light in winter. In the summer the south facing window could get too hot. If you haven't the window space; grow lights could give the light you need to grow your own herbs. The problem of dry heat from a heat register can be alleviated by placing a deflector over the register to direct the hot dry air away from the plants. Increase humidity around the plants with frequent misting and/or a tray filled with pebbles and water, can be placed under the plant pots,(the pebbles are to keep the bottom of the pot above the water level).
Plant containers should have good drainage, potted herbs will not flourish if they are waterlogged.
Clay pots are most highly recommended. If pots are set on a saucer or inside another decorative container be sure to drain excess water within an hour of watering, or if the container is large enough to hold several plant pots, fill around the plant pots with peat moss to absorb excess moisture.
Check the soil by prodding with a finger every day and keep the soil just below the surface constantly moist. If you can't provide rain water for your herbs allow tap water to sit for a day before watering or spray misting the herbs. If a plant should become excessively dry, set the pot in a pan of water for ten or fifteen minutes, to allow the soil to become thoroughly saturated.
Soil for herbs needs to be less fertile than regular potting soil, you will need to add peat and sand in equal parts with potting soil. Fill the bottom of pots with a one inch layer of gravel, broken brick or pot chard's so that the drainage holes will remain free flowing.
Herbs need very small amounts of organic fertilizer a mixture of blood meal, horn chips, and bone meal can be added at a rate of 2 tbsp. to 4 cups of soil mix, when preparing the soil. Change the soil once a year. Never use animal manure, non organic plant food, or insecticides on herb plants intended for human consumption.
The choice of herb plants is best determined by your own menus, grow the herbs you need for your favourite recipes. The easiest herbs to grow would be chives, thyme, basil, cress,and chervil. Divisions of herbs such as chives,summer savory, marjoram, basil, lemon balm, oregano,lovage, and parsley grown outdoors can be potted up and gradually acclimatized to indoor life. Some herbs such as sage, rosemary, thyme, and bay can be started from cuttings taken in summer and rooted in a mixture of peat and sand. Herb plants could be purchased in the spring and early summer from our local growers. Starting herbs from seed is probably going to give the greatest selection. Seed catalogues are available from many suppliers.
Search the Internet for seed suppliers. www.Richters.com would be a place to begin.
