Indoor Herb Garden

Care for your Indoor Herbs

For gardeners who like to cook, few plants are as rewarding as herbs. When the outdoor growing season ends, you can still enjoy fresh, homegrown herbs in your favorite recipes.

You can simply dig up your healthiest herbs and bring them inside. By taking note of herbs’ special growing needs, you can harvest basil, thyme, and more straight through until spring.

Herbs can be grown successfully indoors if you give them a little extra care

Here are three steps for successfully bringing herbs inside:

1. Choose the most robust plants to bring indoors.

Before the first frost, dig them out of the garden and pot them up in fresh potting soil. Choose pots that allow for at least 3-5 cm (1-2 inches) of space around the rootball. Water thoroughly. Check each plant for insects, and if there’s an infestation, treat the leaves with a soap spray.

2. Reverse the hardening-off process.

Keep the pots outdoors out of direct sunlight for about a week. This will accustom your plants to being in containers and to the lower light conditions they’ll experience inside. Keep them watered. Prune any lanky growth.

3. Bringing the potted herbs inside.

To stay flavorful, herbs need at least five hours of direct sun a day. Turn windowsill plants regularly so that every side receives light. Don’t let leaves touch the cold window glass. Fluorescent lights, hung 15 cm (6 inches) above the plants and left on for 14 hours per day, give even better results. Most indoor herbs prefer temperatures of about 18-21 degrees Celsius (65 to 70 degrees Fahrenheit) in the daytime and about 15 degrees Celsius (60 degrees Fahrenheit) at night. Herbs also need humidity. Provide it by placing the pots on trays filled with gravel and about 2 cm (0,75 inch) of water. Protect plants from drafts, but give them good air circulation. Don’t crowd pots together. Overwatering will kill most indoor herbs, so between waterings, let the soil surface dry out – and use tepid water. Fertilize once a month with diluted fish and seaweed fertilizer.

Basil (Easy)Keep snipping to prevent flowering. When plants become woody, compost them and start more from seed.
Chives (Easy)Pot up the plant and leave it outside until frost kills the foliage. It will resprout in a few weeks.
Mint (Moderate)Mint prefers cool, humid conditions. To allow for its spreading root system, make sure the pot is wider than it is deep.
Oregano (Easy)This herb likes good drainage, slightly dry soil, and regular pruning.
Parsley (Moderate)Challenging to transplant because it has a deep taproot. Surest success? Start from seed.
Rosemary (Finicky)Rosemary needs moist air and well-drained (but not dried-out) soil. Brown needle tips mean you’re overwatering.
Sage (Easy)Forgiving when you forget to water, sage is kept in bounds by regular pruning.
Thyme (Easy)Thyme can handle some shade. Compost once stems become woody.
