Hi, I'm Jene with Jene's tropicals in St. Petersburg, Florida. Today, I'm going to demonstrate how to trim grapefruit trees and orange trees. The materials you will need will be sharp pruners, alcohol to clean your pruners, so you have healthy cuts, and a can or jar of pruning sealer. The first thing you need to do is examine the tree and prune any old and decaying wood and one of the main reasons is insects and bacteria feed on the dead wood. The next step would be to examine the shape of the tree and if you have any criss crossing branches or any growth pointing downward, you want to take those off. Basically you want your tree to grow as a shape of an umbrella so you have very good air circulation. This will help the tree fruit better and it'll cut down on disease like fungal diseases and insects. The third step would be after you've taken the decayed wood and any criss crossing branches out, examine what you have left to work with and then just simply go through and tip some of the branches. So after proper pruning maybe once or twice a year, you should have an abundance of flowers and fruit during the winter through springtime. Thank you. I'm Jene, and have a wonderful day.
