Growing herbs indoors assures a constant supply of seasonings for cooking, adds greenery to the indoors and fills the area with spicy aromas. Planning and growing an indoor herb garden is relatively basic and problem-free providing gardeners meet the particular herb’s requirements. Some herbs grow better indoors than others (see Resources). Due to their large root systems and large container requirements, herbs such as fennel and lovage grow best outdoors.
Choose the herbs you'd like to grow in your indoor herb garden. Select herbs that are compatible growing together, with similar water and light requirements. Herbs such as rosemary and sage prefer bright light, whereas mint and lemon verbena prefer filtered sunlight.
Use herbs in the same container that have various textures and growth habits for a more interesting and appealing look. Use an upright herb planted into the container’s center, such as basil or rosemary, with a vine-like herb like oregano that can droop over the container’s side.
Plant a themed herb garden such as a salad garden that contains herbs such as dill and chives. Use herbs that have appealing smells, creating an aromatic herb garden. Herbs such as lavender and rosemary have both culinary and aromatic uses and smell good when watered.
Select the container or containers in which you will be growing the herbs. Whether you will be planting the herbs singularly or bunched together into one garden, choose a container that will accommodate the herbs and has good drainage.
Use a potting mix that drains well and does not retain water. Herbs planted in potting mediums that retain water are more likely to develop root rot.
Place the container in a southern window to assure adequate sunlight. For proper growth, herbs require approximately six hours of sunlight daily. Plants become straggly and have smaller leaves when not receiving enough light.
Place the herb garden in an area that is warm and the indoor temperatures range between 60 and 70 degrees Fahrenheit for proper growth. Herbs grow best situated in indoor locations that are consistently warm.
Water the herb garden when the soil begins to dry out. Apply the water in the morning allowing excess moisture in the container to evaporate throughout the day. Over-watering the containers can cause the herb’s roots to develop root rot and die.
Create humidity in the herb garden by misting plants with water two to three times per week, grouping herb containers together, or placing the herb garden in a dish filled with wet pebbles. Herbs require some humidity for proper growth.
Fertilize the herb garden with a half-strength water-soluble fertilizer every other week throughout the growing season of spring throughout summer. Fertilize once per month during winter.
