May 10, 2020Q.We pruned a silver birch tree heavily in February. Will it survive?
Hello Having read your advice, we now realise that the tree was pruned at the wrong time. It had been getting very big and the foliage was too dense in the summer. Our idea was to make the tree smaller and less dense. The tree is still alive but with very little foliage.We are wondering is it likely that (1) the tree will survive and (2 will it develop healthy levels of foliage again, perhaps during next and subsequent years?

Certified ExpertA.Yes, it will likely recover, but it may take quite awhile. The growth may be set back two years or so. Unfortunately, this is the importance of pruning at the correct time depending on the species.

May 30, 2020Q.Can borers fatally affect a paperbark tree and make it dangerous?
The tree is located close to the home and appears to have been attacked by borers and or white ants because there are many holes in the trunk. We are concerned that it may have been weakened and fall on the house. It appears the roots have caused a cave in near the sewer. A friend said it may be wasps but we have seen none.

Certified ExpertA.On a general basis, when you began to see trunk damage the issue has been going on for awhile. It is often easier to replace the tree than treat it for borers. I can't speak to the safety of your tree and would recommend you have a qualified Arborist look at the tree.

Certified ExpertA.The River Birch will be your best bet. Most are not tolerant of warmer zones, and this one will go all the way up to zone 9!

Certified ExpertA.Your course of action will depend on what is eating your leaves. Unfortunately, your photo did not come through, so I am unable to see the damage.
My guess will be insect damage. In that case, you will need an insecticide.

Certified ExpertA.I notice that the braces are still on a decently mature tree. Typically, these are removed once the tree is established. If this is a fresh planting (less than a couple of months) then I would be inclined to say that it succumbed to an infection. This is common with fresh plantings that are overwatered just a bit at the time of planting.
Otherwise, even under proper condition, blights can take over and kill trees, seemingly, almost instantly.
The most common causes for this will be Anthracnose and Tree Borers. Both will exhibit these symptoms.

Certified ExpertA.Unfortunately, your photos did not come through. I will be unable to assess the damage.
There are several things that can cause this, and the tree will need to be well inspected for signs of what could have caused the death of the tree.
Here is an article that will give you some of the reason that this can happen:

Certified ExpertA.The best time for pruning your tree would be late summer or early autumn. As for supporting the tree, your best help will come from a certified arborist in your area, or you may want to contact your local university extension service for some help with this:
