Nectarine trees are susceptible to a number of problems, including pests, diseases, and poor fruit production. By pruning your nectarine tree you can encourage new growth and improve the quality and quantity of your nectarine crop.

Pruning Basics
Pruning is important for the health of your nectarine tree and for the quality of the fruit it produces. Correct pruning techniques improve air circulation and make it easier to spot problems early. It also encourages new growth and fruit production.
Why prune?
The primary reasons to prune a nectarine tree are to:
-keep the canopy open so that sunlight and air can reach the fruit
-prevent branches from breaking under the weight of the fruit
-direct growth for a more compact, bushy tree
-promote fruiting by encouraging flower bud production
Pruning also helps to prevent disease by removing dead or diseased wood and promoting good air circulation.
When to prune
Nectarine trees need little pruning, with the exception of young trees. Once your tree is established, annual pruning will keep it healthy and produce the most fruit. The best time to prune your nectarine tree is in late winter before new growth begins.
There are a few things to keep in mind when you prune your nectarine tree:
– remove any dead, diseased, or damaged wood
– remove any suckers growing from the base of the trunk
– thin out crowded branches to promote good air circulation
– cut back unwanted growth
What tools to use
The actual pruning of a nectarine tree is not difficult, but it is important to use the proper tools to do the job right.
First, you will need a sharp pair of pruning shears. You can find a good pair of shears at any gardening center or nursery. Be sure to get a pair that is comfortable for you to hold and that cuts cleanly. Avoid rough, jagged cuts as these can damage the tree.
Next, you will need a saw for any branches that are too thick for the shears. Again, get a saw that is comfortable for you to use and that makes clean cuts. A damaged branch will not heal properly and can lead to disease or pests in the tree.
Finally, you will need a ladder if you cannot reach the top of the tree without one. A stable ladder is essential for safety while pruning. Do not try to stand on an unstable chair or stool as this could result in serious injury.
With the proper tools in hand, you are ready to begin pruning your nectarine tree.
Pruning a Nectarine Tree
Pruning a nectarine tree is an important task that should be done in the late winter or early spring. Nectarine trees need to be pruned in order to promote new growth and to remove any dead or damaged branches. Pruning also helps to encourage fruit production.
Remove dead, diseased, or damaged wood
Each cut you make should have three purposes:
-Remove dead, diseased, or damaged wood
-Thin the canopy to increase air and light penetration
-Shape the tree
When pruning, always make your cuts just above a bud that is pointing in the direction you want new growth to occur. If you can’t find a bud, make your cut at a 45-degree angle just above a healthy branch.
Remove crossing, rubbing, or weak branches
To ensure good air circulation and light penetration, remove crossing, rubbing, or weak branches. These branches can be removed any time of year.
Remove suckers and water sprouts
Suckers are fast growing stems that sprout from the roots or lower trunk of a nectarine tree. They are often mistaken for new fruit bearing branches, but they do not produce flowers or fruit. Suckers should be removed when they are young to prevent them from sapping the tree’s energy.
Water sprouts are also fast growing, but they sprout from the main branches of the tree. They are generally thinner and more upright than fruit bearing branches. Like suckers, water sprouts do not produce flowers or fruit, so they should be removed.
Thin the canopy to increase air and light penetration
To thin the canopy of a nectarine tree, selectively remove limbs throughout the tree. Begin by removing any dead, diseased, or dying limbs. Next, remove any crossed or rubbing limbs. Finally, remove any weak or slender limbs that are growing vertically. These vertical limbs are often referred to as “water sprouts.” Once you have thinned the canopy of your nectarine tree, you should see an increase in air and light penetration throughout the tree.
After Pruning
Check the nectarine tree for any damaged, dead or diseased wood and branches and prune these away. Also prune any branches that are growing inwards towards the center of the tree or that are crossing over other branches.
Apply a wound dressing
Once you have finished pruning your nectarine tree, it is important to apply a wound dressing to all cuts that are larger than ¼ inch in diameter. A wound dressing helps to prevent disease and insect pests from entering the tree through the pruning cuts. For best results, use a commercial wound dressing or a mixture of 1 part paint to 9 parts water.
Mulch the base of the tree
Organic mulches help retain moisture, keep roots cool and suppress weeds. Pull back the mulch from the trunk of the tree to avoid collar rot. A 3-inch layer of wood chips, bark or straw is sufficient.
