77532Q.Arizona ash trees
The roots on this mature Arizona ash tree are getting close to the house and I'm afraid the may disrupt the slab. I don't want to loose the tree so I was wondering if I could kill the outer most roots that are danger ing the house and the tree would not be affected.

June 13, 2018A.Daniel; Lateral roots more than 12 - 15 feet from the tree trunk will not likely lift or crack a substantial concrete house foundation. But they can undermine, lift and crack a less substantial structure like a garage floor. Of course un-reinforced slabs, garden walls and headers are more vulnerable.
You can probably get away with cutting a limited number of the lateral roots without severely harming the tree. Root prune with clean cuts, don't poison them with herbicide or the chemical could translocate into the parent tree and cause harm.
Install an 18" to preferably 24" deep root barrier to retard re-growth of the roots in that direction. I believe that plastic/composite root barrier material is available at home improvement and garden supply stores like Home Depot and Lowes.
Some things to keep in mind: cutting a large percentage of the root system can affect the physiological health and sometimes the structural integrity of the tree. Roots are there for uptake of water and nutrients.
The closer you cut to the trunk, them more potential for harm and for destabilizing the tree, making it vulnerable to wind-throw toppling.

Johnston, IAQ.Growths under ash trees
Some ash trees in the Iowa area have growths on the ground under the ash trees, apparent from the roots near the surface. They initially appear to be mushroom like, but then turn into a dark brown ugly semi-liquid. What are they and what should be done with them?

Certified ExpertA.Without a photo I couldn't be completely sure, but it sounds like tar cap mushrooms. Once the area dries up significantly, they will go away on their own.

October 8, 2018A.I don't know where you are located or what species of ash you are referring to, but I've never heard of ash seeds being poisonous to dogs, and I can't find ash on the ASPCA list.

March 3, 2019Q.Aphids on Raywood Ash trees
Is there anything that could be put at the base of Raywood ash trees to detour aphids on our mature trees? We have 5 beautiful mature Raywoods in our parkway,that in the last couple of years have been covered in aphids. The trees seem to do alright, but then the aphids go after other plants. My thinking is if I can control them in the trees the infestation in the rest of my yard wont be as bad.

March 4, 2019A.There are many ways to help this. I use neem oil for aphid control. Just make sure that if you are spraying on any leaves to do so when it is cloudy, or not in full sun.

December 5, 2019Q.Claret Ash losing its new growth
I have three claret ashes all in a row, planted the same time about 10 years ago. One shot up and is over double the size of the others, it goes into seasons slightly later than the others. The issue is that the new growth on this tree is falling off when the others are bushy and healthy. There is a bit of growth at the top of the tree but the rest is barren as the leaves fall off after a week of growing. Any ideas? kind regards, Gabrielle

Certified ExpertA.Even with proper planting, watering, soil content, fertilizer, a new planting may not survive and reasons for this to happen may not be known. Most reputable garden centers guarantee their trees, shrubs and some perennials for 1 year.
Do the branches snap off or are pliable? Do a scratch test on the bark. The link below explains this method.
And give the tree a bit more time to wake up. If no signs of life; check with the seller for a replacement.https://www.gardeningknowhow.com/ornamental/trees/tgen/watering-newly-planted-tree.htm
