How to Grow Herbs

In this article, we share a comprehensive guide to growing herbs at home.

One of the most rewarding parts of having a garden is the abundance and easy availability of fresh herbs. Afterall, fresh herbs add a transformational punch to any meal, far superior than their dried counterparts. Not to mention most herbs are easy to grow and take up little space in your garden. Many herbs also make great companion plants that can help repel pests and improve the health of your plants.

Propagating Herbs by Cuttings

While you can purchase herbs in any nursery and even supermarkets, they are also easy to propagate by cutting. Most herbs make good candidates for this method, especially all that are in the mint family (Lamiaceae).

1. Take a fresh cutting about 6” long of healthy growth free of any disease.

2. Place this in a small jar or cup full of clean filtered water.

3. Wait 2-4 weeks until roots develop.

4. Once rooted, place cutting in loose soil well amended with worm castings. Keep soil moist, adding a fine mulch can help reduce evaporation.

5. Alternatively, you can skip steps 2 and 3 and root directly into soil. This often works better for woody herbs like rosemary.

Sweet Basil Quick Guide Information

Common Name: Sweet Basil

Scientific Name: Ocimum basilicum

Family: Lamiaceae

Life Span: Annual or Short Lived Perennial

Basil prefers warmer weather but can be planted outside in the spring 2-4 weeks after the threat of last frost. Amend soil with worm castings to help stimulate vigorous growth.

Basil flowers should be cut back as they develop to help promote vegetative growth. Regular harvesting is also beneficial for the plant, so don’t be shy! If you have too much Basil, making a pesto is a great option for preserving. Try to harvest from the inside to promote airflow and reduce compact growth. After flowering plants will reduce in vigor and no longer produce in the same way. At this point you will need to renew your plants. If you are experiencing rot or seeing signs of disease on the foliage you can cut back your plant and wait for new growth.
