Dried vs. Fresh
Having fresh herbs ready to pick for cooking is the main reason gardeners plant sweet basil.
However, fresh isn’t always best when it comes to flavoring food. Whether fresh or dried, your sweet basil can always be dried for future use.
Dried Sweet Basil
- In the drying process, oils are trapped in the herb during dehydration.
- Flavor: more intense and concentrated
- Add to dishes at the beginning of cooking.
Fresh Sweet Basil
- Fresh herbs are hydrated with water which tend to weaken the flavor.
- 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.

Growing basil from seed is rather easy.

- Place a few seeds (up to 3) in each indentation.
- Gently cover seeds with potting soil.
- Carefully water the entire tray (without flooding.)
- Place the tray in a sunny area or under plant lights. You should see your seeds come to life in about 1 ½ weeks.

Whether you have purchased starter plants or have your rooted cutting, it’s important that if you plant outdoors, you wait one week after your last frost.
If you or a friend have a sweet basil plant, you can learn how to grow basil from cuttings.
- Locate a twig that is 3-4” long. It’s important that this twig hasn’t flowered.

- Once your root growth is at least 2”, you can transplant the cutting into a container or outdoors in a garden. Remember, don’t plant outdoors until one week after the last frost.
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.
- Avoid planting in an area where standing water or flood is a problem.
