I have 2 cottonless cottonwoods in my back yard. They are both about 7 years old. I noticed this spring that the trees have really grown tall but on the main limbs in the middle of the trees there are no limbs coming from them. I also find little pieces of new branches all over my lawn like they have come off right at the base where they connect to the tree. There are also at those points little scabs of some kind right where the branch has broken off. What is wrong and can I save these trees? I grew this kind of tree because they are fast growing trees and I wanted to enjoy some shade while I was still around to enjoy it. I am so afraid that there is something seriously wrong and those years will be lost. Can you help me with the info I have given you? I would appreciate it so much if you have an idea of what is wrong and what I can do to fix it.

Cottonwoods and willows are subject to a large variety of serious insect
and disease problems. Though I can't tell for certain from your
description, it is very likely that these trees have (or will get) a
fungal stem canker, a disease that kills part of the vascular system and
causes everything from that point up to die. Cankers can affect small
twigs or larger branches. The only thing you can do is keep the tree
vigorous (meaning water a lot), and prune out any clearly dead material
below the point of death and dispose of it. This is unlikely to help for
long though. Pesticides will not help.
For these reasons I do not recommend the planting of cottownwoods,
poplars, aspens, and willows, except for temporary effect or on sites
where they are native. If a person wants a strong, fast growing tree I
recommend London planetree (sometimes called sycamore).

- We have thousands of little green worms/caterpillars hanging from webs in our trees, eating the leaves til they are bare. What can we do to get rid of them?
- I have a 25-foot tall scrub oak that appears to be dying. If it is anthracnose that is killing it, can it be saved? There are some commercial, injectable products that claim success. Is it possible?

- I live in South Jordan. 4 1/2 years ago I started watering my yard with gray water (irrigation) due to the cost of water. Since that time I have lost 6 red twig dogwoods, 7 blue arctic willows,3 spireas, a pine tree and a Japanese maple. Everything else does not look good (other trees, bushes and perennials). In the spring it all starts out green but by June everything has brown edges on yellowing leaves and the trees have several dead branches. Could the gray water be the culprit? Everything was at least 6 years old, lush, and healthy until I changed my water. I am afraid I will lose everything else this summer if I don't find a cure for this. I could you use some answers. Thank you.
- I am purchasing a 30 year old home with three large (15+ feet) blue spruce trees growing in the front yard. I would prefer not to cut them down, is it possible to transplant a large blue spruce in Utah? If so, who would do it and who would want them?
- I saw a small, dark green, spruce tree planted next to the corner of a home in a nearby neighborhood. Are their dwarf varieties of this tree? It is not an dwarf Alberta Spuce- I have already verified this. If so, what are they called. I would like to find one for my yard.
- I have a very large, beautiful Cottonwood tree on my property, that is near the property line with my neighbor. She wants to put in a new fence, because the tree has been pushing up the posts for her old fence. The fencing company has said that they can put in a new fence, but they will have to "shave off" a bit of the tree trunk and possibly some of the root near the surface of the ground. I am worried that something like that could lead to the tree getting sick or dying. I want to keep peace among neighbors, but it would be a disaster and very expensive to lose the tree because of something likethis. Can you please tell me if a Cottonwood tree is hardy enough to withstand such a "shaving" procedure?
- I have a curly willow that was topped about four years ago. Now it needs to be trimmed. Can I cut the branches back to where they were cut last?
