Information on pruning overgrown plants.

Your goals are to have adequate air flow throughout the plant, remove diseased or dead branches, and have good light penetrating the entire plant.

Remove any branch that is rubbing against another. This can cause an open wound on the branch, which is an opportunity for disease to invade the plant.

Remove branches that are growing toward the center of the plant. Also, remove any branches that cross each other. Remember we want to provide both air circulation and light penetration.

Remove any dead or diseased branches. A dead branch will be brittle, its buds will be brown. While a live branch will be flexible, buds will be green and there will be a green layer under the bark.

Generally, remove 1/3 of the plants’ height or 1/3 of its branches.

Remove any suckers and or waterspouts. These 2 types of branches look similar, growing straight up. However, a sucker originates from the roots or below the graft. While the waterspout will be vigorous and originate from the trunk or large branches.

Wow! I knew that there were efforts ongoing, but this is the first solid timeline I’ve heard - we are just 10 years from staring to reforest the Appalachian mountains with blight-resistant ~American chestnuts, beginning to undo one of the greatest environmental disasters of the last century. If I understand correctly, these hybrids have been selectively bred for generations with the remaining wild American chestnut trees (they will sprout and even flower, but they die young from the blight) until the only observable Chinese chestnut trait left is the blight resistance. The growth habit, leaves, and seed size look exactly like the Native American tree and the hope is that they’ll adopt the same ecological niche as the old American chestnuts (which the Chinese chestnut trees will not).
