Q

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?

Answer(s)

A

The tree that is not leafing out is difficult on email to diagnose the problems.  Can't save the tree without a good diagnosis.  If you have photos you can send me, that may help me diagnose the problem.  Trees often take several years after and injury or onset of a disease to fully manifest problems such as what you are describing.  Problems like root damage due to construction in the root zone is a common problem for trees, or even compaction around the roots, such as playground sets, or picnic table placed under the tree compacts the soil so much, oxygen to the roots is unavailable and slowly tree dies off.

Send photos or else hire a International Society of Arboriculture Certified Arborist, click on http://www.utahurbanforest.org/ and there is a list of certified arborists in Utah, you can contact.
