1. Acer

Asked by Anonymous - May 13, 2011

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?


2. What to Do for Tree That Is Losing Leaves

Asked by Anonymous - May 15, 2011

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?

3. Maple Tree

Asked by Anonymous - May 18, 2011

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?


4. Neem Oil

Asked by Anonymous - May 25, 2011

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.

5. 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?


6. Sap Dripping From Maple Leaves

Asked by Anonymous - May 26, 2011

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.

  • 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.

7. Tree Limb Repair

Asked by Anonymous - June 2, 2011

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.
