Tips on Pruning a Chinese Chestnut Tree

Chinese Chestnut trees, like any shade tree, need pruning to remain healthy. The same basic rules for pruning apply to chinese chestnut trees, but there are some things unique to chestnuts that you need to take into consideration. Chestnut trees actually require very little pruning once established, and don't even need annual pruning prior to that. Some trees will never need to be pruned. Chestnuts are very low maintenance in general, but when pruning, remember these tips.

Tips on Pruning Chestnut Trees

  • Prune only in the fall and avoid pruning at all from April through July
  • Prune limbs when they reach about 1-inch in diameter
  • When establishing chestnuts, prune to establish a clear trunk up to about 8-feet during the first 5-to-10 years
  • Don't prune more than 1/4 to 1/3 of the top in any one year or you'll stunt or kill the tree
  • Prune for health first, then safety, then looks
  • Don't prune limbs flush with trunk and cut outside the branch collar
  • Prune any limbs that cross or rub each other or the trunk
  • Never prune a limb more than 10 centimeters in diameter without a good reason (call in a professional)
  • Think twice before pruning a limb or branch between 5-centimeters and 10-centimeters in diameter
  • Most limbs and branches up to 5-centimeters may be easily pruned without harming the tree
