A pot of basil on the windowsill can teach more than it looks like. At first, you wait because the plant seems too small to cut. Then it gets tall and starts to flower. Then the leaves turn stronger, tougher, or bitter, and the best flavor has already passed.

Herbs do not need a large garden to be useful. A few pots near a sunny window, on a porch, or outside the kitchen door can season meals, reduce grocery waste, and teach the timing that larger gardens require later. The key is learning when to harvest herbs before the plant gets ahead of you.
