I have been told by a tree care company that my ash trees are infected with bores. They can be treated, and the trees should survive. Though my internet research I found ample information on emerald ash bore, however, that the research was largely on trees in Michigan. Would I have emerald ash bores, or do another type of bore exist in Utah? The tree care company suggested treatment in the spring, and another in the summer. Does that sound appropriate?

First I would ask if the tree care company and individuals you had look at your trees were certified arborists through the International Society of Arboriculture (ISA). Here is a listing (not complete) of certified arborist for hire in Utah click on http://www.utahurbanforest.org/certified.html and for ISA information go to http://www.isa-arbor.com/certification/certification.aspx .
Emerald Ash Borer is currently a problem in Michigan, but we have other types of borers in Utah that do affect ash. Here is a link to USU fact sheet on Lilac/Ash borer which is a clear winged moth that has not been updated recently, so the chemicals allowed may not be available http://extension.usu.edu/files/publications/factsheet/ash-lilac-borers93.pdf
A more current factsheet and with pictures regarding tree and shrubs borers is from Colorado State Extension - go to http://www.ext.colostate.edu/pubs/insect/05530.pdf and you'll notice there are a lot or borers but treatments are not always effective - must have proper identification of pest to choose the best management.
If your ash is in good shape and not had a lot of dieback and is has good roots with lots of room for the roots - ashes are big trees and need adequate roots for absorbing water and nutrients and support of a large canopy (not impacted by sidewalks, decks or house foundation) the tree may possibly be worth treating - but make sure they have diagnosed the pest appropriately.

- I have a small backyard that has a house on the west and north side, a cinder block wall on the east side and a large tree shading a portion on the south side. Due to the high sides of our yard, we tried some part shade/part sun plants last year. But they got blasted in the heat. Our yard doesn't get 10 hours of sunlight but it gets very hot. Can I sucessfully grow a vegetable garden in part of it up against the houses and plant something along the cinder block wall - preferably grapes or raspberries, or other covering plants (can be non-fruit). Can you recommend a plant we can grow along the wall, both in the shaded and sunny parts? Any recomendations for better use of the space?
- Do you have any suggestions as to where to buy or how to make a truly sturdy tomato cage? The "standard" metal ones I have bought at garden centers have always tipped over when the plant has gotten big.

- We have several ornamental trees such as flowering pear and cherry, they have holes in the trunk and are weeping in some places.We are trying to save them, we have sprayed them with imidan for a couple years and it has'nt taken care of the problem. It would be horrible if they were destoyed. Do you have any suggestions that would help. We also have several fruit bearing trees that we don't want infested. I understand there is better spray out there but you have to be licensed, I'm not sure how much time these trees have, but we'll do whatever we can.
- We have 2 honeylocust trees in our yard. I would guess "Imperial honeylocust". They seem to be about 15 years old or so. They are spaced about 20 feet apart. This spring one has leafed out and the other is still not budding or leafing out. Over the winter, the one that is not budding turned bright red on the trunk, which we have never seen before. The tree is getting a very few buds and leaves on some main branches (like suckers) but no buds or leaves on the outer limbs. Is there anything we can do to save this tree?
- There is a pecan tree where I work that is dropping leaves like crazy. Can I add the leaves to my vegetable garden and let it compost over the winter? Is there any toxicity in pecan leaves?
- Can I legally drill a small water well (or two) under 30 feet deep in my back yard without a permit?
- How do I eradicate an OLD ivy? This has a trunk like a small tree and vast growth on a wall. I'd like to put in a carport and have been hacking at this ivy but am concerned it will grow back. Can I paint the cut trunk to stop re-growth? Would a copper nail kill it? Thanks!
