![]() Think of branch thickness as the width of a road. Remember that branch caliper plays a key role in the vigor equation.Ideal branch angle for fruit bud production should be between 60 and 90 degrees (90° is horizontal). Experiment with branch angle to manage your fruit trees’ vigor. By pulling upright branches more toward horizontal, you can decrease vigor. Branch angle is the easiest way to manipulate branch vigor.You can control branch vigor by manipulating these three factors. This is why it is important to maintain older branches in the bottom of the tree. ![]() When comparing two branches in a tree, if the branches are the same elevation and growing at the same angle, the thicker branch will be more vigorous. Conversely, if you need a branch to grow more vigorously, pull it into a more upright position for a year. We use a UV degradable tree training band for this, available at CMFC. If you take a vigorous branch and pull it down to a horizontal position, you can nearly stop all of the growth in that branch. The more upright the branch, the more vigorously the branch will grow. The top of the tree will always be the strongest growing part of the tree The lower the branch in the tree, the less vigor the branch has. These three things interact to balance and counterbalance growth within the tree. Three major factors control branch vigor and flower bud formation: branch placement, branch angle, and caliper. All other sets of branches should have about 12″-16″ between them.īranch vigor refers to how strongly a branch is growing. Limb spacing (Branch Placement) on mini-dwarf trees.All other sets of branches only need 2 feet between them. Lowest set of branches should have 24″ min and 36″ to the second set of branches.Bottom set of branches should be about 26″-36″ above the ground.Limb spacing (Branch Placement) on dwarf and semi-dwarf trees (the importance of Branch Placement is discussed below).Pruning does decrease your tree’s fruiting potential by removing wood from the tree, but is necessary for fruiting success. Make sure when you prune, you are cutting into the two-year old wood. In the second winter you can cut the branch back to the desired length. Does that mean letting the young branch you think you should shorten get too long? In some cases, yes. It is important to let the one-year wood grow into two year old wood. Pruned or headed one-year-old wood will develop almost no flower buds in its second year.Unpruned one-year-old wood will develop many flower buds in its second year.If your goal is to produce fruit, don’t prune into one-year wood after the planting.If you prune into one-year wood, the net effect will be to make more one-year wood.If you prune into one-year wood you will delay fruiting of that branch.Utilize training into your pruning program for the best success. Pruning not only shapes the tree, but also determines the quality and quantity of fruit.įirst and second year wood on apple branch In apples, the most productive wood is 2-5 years old. Fruit trees were bred over many decades to bear on young wood. Stretch Tie is a commercial orchard product designed for this purpose, available at the nursery. For all tree tying, we recommend using an expandable material that won’t cut into the tree as it grows. Tie the leader to the stake every 18″-2′. Tie the trunk of the tree to the stake just below the first branches. You may have the fortune of being the recipient of 10-15 lbs of fruit in the second year, but if your tree isn’t staked, it will probably be destroyed by the weight of the fruit even before the wind has a chance. The varieties we sell often begin bearing fruit in the trees’ second year. We live in a windy place the stake not only should be used to hold the tree up but more importantly it can be used to hold the fruit up. Use posts that will be at least 5′-6′ tall at finished grade. To open the tree to light and air circulation.If you’re just planting fruit trees for the first time, you might want to look at the Learn to Grow Fruit Trees page.
