Do you have fruit production in your backyard? This can be a very rewarding and very frustrating part of horticulture production! Fruit trees are not for the faint of heart by any means. Most folks think that they can just stick a tree in the ground and grow fruit but this is far from the case, especially here in Eastern NC.
In a nutshell, soil testing, site prep, variety/rootstock selection, and planting are all important to getting a great start for your production endeavor. The next steps are training and pruning.
Sounds like the same thing right? Nope. Training takes place the first five years after the tree is planted. We train trees when they are young so that they will maintain their shape and structure when they grow older to bear good fruit. Training involves making very selective cuts on the tree to encourage branching in specific areas, encourage crotch angles that will bear heavy loads, and encourage light distribution to the areas where the fruit is growing. There are two types of training, central leader and open systems. A central leader system is trained much like a Christmas tree shape. This is for tree fruit that bears fruit on the branch ends or terminals such as apples and pears. An open center system has no central leader, it is cut out very early to open the center of the tree. This is for fruit trees that bear fruit all along the branches such as peaches and nectarines.
Training also involves encouraging branching or scaffolding in certain areas of the tree. In a central leader system, we want to have whorls of four scaffolds every two feet moving up the main trunk. This can be done by cutting the central leader 6”-8” above where branching should occur. This produces multiple stems, several will grow directly up and several will grow laterally. Training selects one of the straight up branches to continue the central leader. Next, four of the lateral branches are selected for the scaffold branches to bear fruit.
An open system is much different in that the scaffold branches are selected the first year. The central leader is cut out completely and the center is maintained open throughout the life of the tree through pruning. If there aren’t good scaffold branches present on the tree in the first year, we can use the same process as the central leader system to make the branches we want to grow. The central leader will then be cut out the following year.
So where do we begin with our branching? This depends on you! In an orchard situation it is typically 18”-24”. However, in a residential setting, you may want to have it high enough to drive your mower under it!
So, what is pruning? This is the time of year that calls begin to come in regarding fruit tree pruning. These vary from how to prune to when to prune. First, let’s just say that if you’re growing fruit, you need to prune every year to encourage fruit production. I know some of you reading this are saying, “I’ve never pruned and I always have good fruit.” That can be the case but for very few folks, I promise, your time is coming!
