Article: To help the lime tree grow as large and healthy as possible, you'll need to prune it regularly. Aim for a pruning schedule of once per year or once every 2 years. Inspect your tree in the spring to determine if it has dead, diseased, crossed, or tangled branches. If so, plan to prune the tree that year and if not, you can wait until the following year. If you live in a warm climate, you should prune the lime tree after harvesting the fruit for the season. The flowers that will produce limes for the next season will be visible, allowing you to easily decide which areas to prune. If you live in a cold climate, you should wait until the risk of frost has passed to prune the lime tree. Do an online search to find the average frost dates for your location, and wait until after this date to prune the tree so new growth isn't damaged by frost. If your lime tree has frost damage, wait until it has new growth to prune it. If you're pruning the tree right after a harvest, make sure no limes remain on the tree. Carefully pick off any remaining fruit so you can clearly see and access the branches for pruning.
