1. Plant with seeds or a starter plant. You can also buy a starter plant at a nursery or a grocery store.
2. Well-drained soil is good soil for basil. If you grow yours in containers like I do, the container itself needs to have good drainage holes.
3. Keep the temperature fairly warm with lots of sunlight (at least six hours a day). Basil likes warmer temperatures (over 50°F/10°C) so I grow mine in the summer outside. If you’re growing it outside, a layer or mulch will help regulate temperature and prevent weeds from growing. If there’s any hint of frost coming, protect the plants with a covering like sheets or blankets tied loosely around and held in place with rocks, stakes, or bricks.
4. Fertilize the soil about once a month if you’re growing it indoors.Organic or slow-release fertilizers (like compost tea) are best for basil. Just don’t fertilize it below 60°F/16°C.
5. Prune that bitch! Pruning leads to more basil. Start pruning the top leaves at around six inches tall and continue to prune as it gets bushier. Also, pinch off any flowers that you see so they don’t go to seed. That will lead to bland and sparse plants.
