An article about how to grow basil in the spring garden. Written by professional aromatherapist, author, herbalist, and gardener Sharon Falsetto.

Basil (Ocimum basilicum L.) is probably one of the most familiar culinary herbs in your kitchen cupboard, as it’s very easy to grow in a pot on a kitchen windowsill, or in your spring herb garden. Although it’s relatively easy to grow, it is actually one of the most complicated plants to understand aromatically.

In this article, we’ll take a quick look at how to grow basil in the spring garden. To learn more about its aromatic nuances and uses, check out the full article in the Botanical Aromatherapy™ Membership School.

Grow Basil in the Spring Garden

Cultivars and Varieties

Basil (Ocimum basilicum) is a small, annual herb which is commonly found in herb gardens worldwide. Its adaptability to grow almost anywhere has spawned a number of cultivars and varieties. A cultivar is a new plant bred from the original plant by human interaction. An example of this is Ocimum basilicum ‘Genovese Gigante,’ a popular basil cultivar grown in herb gardens. A variety is a random plant within “the geographical range of a species or subspecies [may be] recognized as varieties.”1 An example is Thai basil (Ocimum basilicum var. thyrsiflorum). Varieties occur naturally in nature whereas cultivars require human intervention. 

  • Overall Appearance: Basil is short (up to 2 feet in height) with a square stem.2,3
  • Leaves: Glossy green, large ovate leaves.2,3
  • Flowers: Two-lipped pink-white flowers situated in whorls, typical of Lamiaceae plant family characteristics.2,3
  • Essential Oil: A steam distillation of the leaves (and flowering tops) produces an essential oil.

Basil in the Spring Garden

Basil is most successful when grown from seed indoors. I have unsuccessfully tried to grow it direct sown outdoors and it is a slow (or non) starter if not given the “right” conditions to grow in. However, I have had good success in growing it in the greenhouse.

How to Grow Basil in the Spring Garden: Sow basil seed in seed pots indoors 6 – 8 weeks before your last frost date for your area. Basil requires several hours of sunlight per day to germinate and grow and it needs soil with a pH of 6 – 7.5. Do not overwater.4 Before transplanting the seedlings outdoors, make sure that the outside temperature is warm enough. A temperature of 80-90 degrees F is optimum for basil, as it’s a tropical native. Plants also need to be gradually hardened off before transplanting into the outside herb garden.

Garden Benefits: Basil works well as a companion plant, particularly when planted with tomato (Solanum lycopersicum). It can repel flies and mosquitoes5 (a therapeutic benefit of the essential oil as well) and like many plants attracts pollinators like bees and butterflies.
