Acer

I have an Acer of about five years old in a large pot. It seems to have a sticky substance on some of the leaves and some of the leaves are rippled. Other than that it’s quite healthy. What could these problems be please?

Sticky leaves are typically caused by either scale or aphids. Look closely at the underside of the leaves for small bumps.

What to Do for Tree That Is Losing Leaves

I have a maple tree that we planted about 15 years ago in our yard. Early this spring I found evidence of moles and grubs. I ‘treated’ the area with cayan pepper.   Now the tree has unhealthy looking leaves on it— loses leaves in the wind— will it heal itself or should I do something?

Maple Tree

I have a red maple tree about a year old. It had buds in Feb. , but they froze. The tree has no leaves on it, but it has new growth at the bottom coming off of the tree roots. Should I cut the large dead tree off or wait and see if it will grow leaves?

This was a hard winter on plants. It is possible that the upper part of the tree did not survive. The shoots from the ground are suckers and it is an attempt by the still living roots to save itself. The suckers will grow but it's may become more shrub like. This article will help you determine if the upper half of the tree is dead: http://www.gardeningknowhow.com/plant-problems/enviromental/how-to-tell-if-a-plant-is-dead-and-how-to-recover-an-almost-dead-plant.htm

Neem Oil

My silver maple has anthracnose and I had an arborist drop by to confirm. She had mentioned she could spray with neem oil. While I was out of the house, they sprayed the tree, but I see no signs [visual/odor] that the tree had been sprayed. Should neem oil leave some signs on the leaves, as I smell or see nothing?

It does not have too much in the way of smell, and because it works systemically from within the tree, not very much is needed to control any pests. It is normally sprayed on in a watered down solution to cover the plant and then the water evaporates, while the neem oil is absorbed into the tree. It is very possible that you would see nothing on the tree if it had had a few hours to dry. While it is primarily used as an insecticide, it is also an excellent fungicide, so it is effective against anthacnose, which is a fungus. Neem oil is an all round, near perfect spray for plants as it combats a wide variety of problems.

Red Maple Tree

Last fall we transplanted a young red maple tree. In the spring, leaves bloomed on less than 1/3 of the tree. Some branches look like they are dead. Any way to rejuvenate the tree?

This happened to ours. All I did was prune down the branch until I hit "good" wood, then walked away. It's fleshing out beautifully. Prune it now, in spring.

Sap Dripping From Maple Leaves

If I tapped the maple trees in the spring, would this reduce or stop the sap from dripping from the leaves? This year it has been the worst I have seen it in twenty years.

ANSWERS

I would simply leave it alone, unless you want to make some syrup from it. Typically, trees such as maples will "bleed sap" in the spring from openings or wounds in the aerial parts of the tree. Once the foliage elongates, the sap usually stops flowing.

Tree Limb Repair

I have an 8-year-old maple that is growing beautifully. Unfortunately, I noticed a limb has split but has not broken off. I used rope to support the damaged limb but need a more permanent fix. Would it be acceptable to use large wood screws and screw the limb back together? The limb is about 2-3 inches in diameter and has split down the middle.

Yes, you can try this. If possible, do not drill through the very center of the branch, but rather on the sides of the heartwood.
