If the eggs were to hatch, you would have a huge amount of moth larvae crawling around through your tree and into your fruits. I don t know about you, but the very thought of this makes me wretch. I once had a friend who was dealing with a very bad moth infestation. He couldn t find a single fruit on his tree that didn t have a worm inside of it. The pathogen which causes these cankers usually enters the tree through older wounds. If you prune all of the sprouts that occur in late summer, cankers will have a harder time making themselves known within your tree. When you prune, always allow the wounds to heal naturally rather than use the wound dressings that you can buy at gardening stores. You should usually wait until it has been established for about a year. The fertilizer that you do add should be sufficiently watered down. If you are trying to grow a tree speedily, there are many more things that you need to consider. However, with proper planning you can create the perfect environment for the tree to spring right up and provide you with plenty of shade within months. However, the shape is slightly different. The same central vertical stem is used, but the connected branches are not horizontal; they grow in the same pattern as a standard tree, only they are two dimensional rather than three dimensional. They are also used to save space, and are used instead of espalier trees for certain types of trees that do better with sloped branches. Generally in an orchard, the trees are planted in a row, then pruned to be in a two dimensional shape. This is known as either a fan or an espalier shape. There is one main branch in the center that is completely vertical, then multiple branches that go off to the side. If the side branches are horizontal it is known as an espalier. Rather than just cut off all the branches that aren t going in the right way, you try to redirect them. The mechanisms you use can be thought of as orthodontic braces for your fruit tree. They pull or push the branches, like teeth, in whatever direction you want them to go. Eventually they naturally grow that way due to your training.
