Dried vs. Fresh
Having fresh herbs ready to pick for cooking is the main reason gardeners plant sweet basil.
However, freshness isn’t always best when it comes to flavoring food. Whether fresh or dried, your sweet basil can always be dried for future use.

- Add to dishes at the beginning of cooking.
Fresh Sweet Basil

- Flavor: subtle with a more herbaceous taste
- Add to dishes at the end of cooking.

Lastly, if you have a sweet basil cutting, you can root one and then plant it.

Planting Basil Outdoors
Where does sweet basil grow best outdoors? It requires full sun, so an area with exposure to at least 6 hours of sun is best.
- Avoid planting outdoors until the soil is warm (70 degrees F.) Sweet basil requires warm soil and warm weather to survive. If the night time temps in your area are below 50 degrees (F,) delay planting until you have warm days and warm nights.
- If you plan to use your basil in cooking, the soil it’s planted in must be clean and free from chemical treatments or pollutants.
Sweet basil thrives best in full sun. It can grow in partial shade but won’t be as robust. These plants require 6-8 hours of full sun.
Having fertile soil is a must for sweet basil. If you plant your basil in an outdoor garden, be sure to work in 2-4” of compost into the ground.
- Don’t plant in soil that’s clay or compacted soil.
- Be sure the soil is well-draining.
