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.

March is a busy month for me.

I run around administering birth control several times a week.

Not to people, I don’t have that sort of training.

Suppressing fruit or seed pods from a tree can have a number of benefits. Sweet gum trees create spikey balls that weigh down branches and sometimes cause failures, tripping hazards and at the very least create an annoying mess on people lawns. Acorns from Oak trees can be an annoyance for folks who don’t want to hear them dropping on their roof all year long. This is not to mention undesired fruit production.

The trick is timing. This fiasco usually starts in early March with cherries. You see, I have to catch the tree in a very specific stage. I’m waiting for the tree to ovulate. Yep, trees ovulate in case you didn’t know. Depending on specie, their buds will start to flower at different times in spring. It has no bearing on what the leaves are doing, I’m watching the flower buds. If they make it to full flower, they will have been pollinated by our local bee population. Then that flower turns into a fruit or seed. It’s been fertilized. Sound familiar? Nature uses the same tricks in different forms and I think it’s beautiful.

This treatment does not harm the bee population. It’s an injection that doesn’t harm nearby trees, does not have lasting effects and can be skipped in order to allow the tree to produce fruit the following season.

This is another way arborists can improve people’s relationship with trees as an alternative to removal. Once they are gone they are gone and we advocate for retention whenever possible.

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).

Apparently trees have lawyers.

I thought about this Ginko tree for a month and finally decided to splurge since my other Ginko tree is still teeny tiny.

I love him ❤️❤️
