Training Your Apple Tree

Training your apple tree

Just what do experts mean when they say 'you need train your fruit tree?" Home orchardists need to train for tree structure to encourage fruit production to have a productive, high yielding home orchard. The branches need to be positioned to allow good sunlight throughout the canopy to promote fruit production from the interior to the outside of your tree canopy. This will also let air circulation in the canopy, reducing leaf and fruit diseases, so you benefit in two ways. Proper training also allows the fruiting branches to support the fruit load without additional support.

Using dwarf apple trees as an example, you will likely use what is called the central leader system to train your trees. The central leader system allows your fruit tree to look like most other trees in your landscape, yet produce apples without the tree looking like those you see in a commercial orchard. Training starts the first year you plant the dwarf trees. This will ensure your dwarf tree actually remains dwarf in your home orchard.

You will be able to start to select your scaffold branches placing the first set of scaffold branches no more than 24 inches from the ground. By starting that low, you will be able to place additional scaffolds and still have a mature tree that is no taller than 6 to 8 feet tall, making it very easy to manage. That may be too low to mow easily, so consider a large ring of mulch that extends to the edge of the canopy. This mulch ring can be increased in size as needed. If a dwarf tree is allowed to grow without being well trained, that fruit tree will be much larger that you planned for and fruit production will likely be delayed.

There are several other advantages of a well trained dwarf fruit tree. Annual Spring pruning will be visually much clearer as to what branches will need your attention. There will be branches that need to be adjusted using traditional branch spreaders or alternative methods such as using twine and a stake to pull the branch into the desired horizontal plane you need as you develop your scaffolds. Water sprouts are easily identified as they will be growing straight up from the horizontal scaffold branches. Foliage and fruit treatment will be much easier as the scaffolds will allow easy access to the entire canopy. Harvest is much easier and a lot more fun too.

As your dwarf fruit tree matures, home orchardists will realize there are additional benefits. The weekly inspection and monitoring of fruit pests will be easier and done very quickly. Even though young fruit tree may not be producing apples, there are insects and foliar diseases that need to be taken care of. Foliage feeding insects reduce the canopy, reducing the amount of food that could go into growing and developing. Leaf diseases have a similar impact. If allowed to continue over the season or seasons, it could easily delay fruit production and limit the number of high quality fruits you are able to harvest. You want a tree that develops quickly, yet one that you have trained to encourage flower and fruit set. Enjoy the challenge and amaze your friends with fruit that came right out of your yard.
