I have 2 basil plants that are in 8 inch diam. pots. They were outside but were doing poorly so around the middle of the summer I moved them inside. They are now thriving! I generally harvest a few leaves at a time while cooking and I cut back any branches that get too tall. The lower stems are starting to turn woody but the plants are still growing well.
How long can I continue to do this? Will a be able to harvest a consistent small amount of basil forever or should I take all the leaves and make pesto at some point (like I would have done if they were planted outside)?
