Certified ExpertA.This can be caused by either a fungus or a pest. But there are several of each that it could be. I would recommend treating it with a general pesticide and fungicide. Consider using neem oil as it is both a pesticide and a fungicide, so you would only need to apply one spray. Plus it is safe for people and pets.

May 22, 2012Q.japanese red maple tree
Over the past 4-5 years, the trees leaves are progressively getting thinner, and the tree is losing its canopy. I would say that there are a growing number of very small branches that are dying. I try to remove these as they develop, but the tree is about 20 plus feet high, so I can't always reach them. The tree is about 30 years old. Is it just too old? Would it help to trim some of the established but thinner branches? The leaves look healthy and I find no signs of disease on the trunk.

Certified ExpertA.It could be too old, but these trees tend to be longer lived than this. 30 would be on the low end of its life expectancy.
It could possibly be a fungus or, less likely, a pest. Treating the tree with both a fungicide and a pesticide will treat both possible issues.
Ideally, I would recommend having a tree specialist look at the tree. Many tree problems are very hard to diagnose without being able to visually inspect the tree.

May 25, 2012Q.My Japanese red maple is getting very thin
My tree is 30 to 40 years old, over 20 feet tall. I can see no sign of disease. It used to be when you would look up, the tree canopy would block out the sky. Now you see more sky than leaves. Is there anything I can do to restore my tree to its old form?

Certified ExpertA.It is possible that it is declining due to old age, especially if it is a smaller variety of Japanese maple. Plants, like animals, have a lifespan and will die eventually no matter how well we care for them.
That being said, there are things it could be other than old age. It could be a fungus, a pest or lack of nutrients causing it to thin out. Treat the tree with a pesticide and an herbicide, like neem oil and fertilize with a nitrogen rich fertilizer. These will take care of a significant amount of what environmentally could be wrong with the tree.

Certified ExpertA.It's difficult to put an exact number on this since it really depends on its current growing conditions and other environmental factors, but on average they can live upwards of 50 years or more.

June 5, 2012Q.Japanese Maple Help
Recently, my maple's leaves all dried up. They remain on the tree and are still red. I've been checking on it daily and noticed just today that it seems to have some type of borer. I saw one hole and upon peeling the bark back, there was sawdust under. Can I do anything to save this tree?

Certified ExpertA.Because it is borers, I would recommend neem oil to treat the plant. Neem oil is a systemic pesticide, which means the tree actually absorbs it and it flows through the tree getting even pests on the inside of the tree. If this tree is important to you, I would also recommend having an arborist look at it.

June 14, 2012Q.Japanese maple that appears to be dead :-(
We moved to the middle of France, at 550m altitude, 5 years ago with a much loved Japanese maple in a smallish pot that had thrived in the UK and here for the first 4 summers. We had freak weather conditions of -18°C in February that lasted a couple of weeks. In March we had freak hot weather and the tree started to form buds but one night the temperature dropped to -5. The buds susequently died and the tree now appears dead. I have tentatively snipped some small branches off to see if it is still alive and I am not sure. I am afraid to cut too far for fear of damaging an already traumatised plant. Please advise. I am so gutted that I will not see the majestic red leaves this year, it is such a wonderful feature at the front of our house. Advice on how to proceed would be much appreciated. Many thanks, Andrea
