As soon as you start to see a branch that is deteriorating or becoming unhealthy, chop it off right away. At the very least, trim down the unhealthy part but leave all the segments that still look like they could continue growing. Once your tree has started to enter the picking stage, never leave any of the fruit on the ground that is bound to fall. Trees grown in containers are ok to plant at almost any time of the year. If the tree just has bare roots, then the ideal planting time is anytime in winter and early spring. If you buy a tree that has been grown in a container, make sure that the roots are not constricted by the container. This will usually cause the roots to go in circles underground after you plant it. Another part of making sure that your fruit tree stays healthy is planting it in fertile soil. If you plant anything in soil that doesn't have the proper amount of nutrients in it, it will not grow and flourish as I am sure you would like it to. You also have to be sure that you plant the right tree in the right kind of soil, because some types of fruit trees do better in drier soil while some kinds or trees do better in damp soil. These allow for long rows of trees, while still producing large amounts of fruit. If you operate an orchard, you probably use this shape to fit as many trees as possible into the area you have. Fan trees use the same theory as espalier trees. 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. You have to make sure that is has enough nutrients, it has enough moisture, there is proper water drainage so your tree doesn't drown, and it is the right texture. If your soil doesn't have these traits then your tree won't grow very well or produce good fruit. You can always alter your soil to be more suitable for your tree. Once you have a plastic animal along with reflective items and noisy items, almost all birds will be too terrified to even go close. While airborne creatures might take a little more than their share of fruit, you should still consider leaving one tree exclusively for them. While they might seem like a pest sometimes, birds can be the one thing that livens up your garden.
