Basil grown from seed will always be strongest and it is really easy. Once established, clip it right above the first set of four leaves and continue to do so every time you clip it and it will reward you with large and bountiful healthy leaves all season long. Once it goes to seed, it gets bitter and there is no going back so keep an eye on it!
If you can’t keep up with your basil, make some basil pesto! It stores incredibly well in the freezer and also makes a great gift for friends and neighbors.
