This plant enjoys areas of full sun (6-8 hours). 

Keep your basil consistently moist in well-draining soil to ensure a good crop. Do not let it get heat stressed, or it will wilt and damage the leaves. 

Medium humidity at 50% or above will give this plant longevity and keep the soil more moist.

Add humidity around this plant to protect the leaves from wilting and getting heat stress. Temps below 40°F will destroy this plant.

Can be grown as an annual elsewhere! 

Apply your fertilizer every six weeks around the drip edge of the plant or sprinkle some rich compost around the area. Container garden: If growing in a container, fertilize monthly with an organic balanced fertilizer. 

Prune the plant slightly above two sets of leaves with sterile sharp scissors. (Do not pinch or tear the stems or this could lead to disease and a bigger wound.) Count up from the bottom and go up at least three sets before pruning. 

Cut tender, young stems with at least four nodes (where the leaves grow). Cut the stem 1/4 " below the bottom node. 
Remove the lower leaves, place the cuttings in water jars, and fill up to 1-2 inches of the stem. 
Change the water every 4-5 days. 
Once the roots are three to four inches long, the cuttings are now ready to be planted. 
Fill the containers with potting soil to about 2/3 full. Take the cuttings out of the jar and plant them into the well-draining potting mix. Cover the roots with more soil until it fills up the pot. Carefully pat them down to make them secure, and water them. 
Over the next 1-2 weeks, keep the pots consistently moist and place them in a bright area out of direct sunlight.
