However, basil is prone to fungus, so keeping airflow between plants is important.
How far apart should basil be planted. Place the seedlings 12 to 24 inches apart, based on seed packet or nursery directions. Most varieties of peppers will need between 12 and 18 inches of space between plants, from stem to stem. Set an odd number of seedlings in the back row.
Space your basil plants 12 to 16 inches apart to allow plenty of sunlight and airflow. Each plant should be about 12 inches apart to allow for adequate air circulation. Basil seeds typically just fall off mature plants to seed themselves for next season, using neither.
