My trees are dying!
I am so frustrated. We've pulled out two trees already this year. It looks like two more are dead or dying.
I am a careful gardner. I researched my tree choices carefully. I also am careful about how I plant/care for my trees. My soil is VERY alkaline. But we use chelated iron and watch the trees carefully.
These are the trees that we've lost:
1) Amur Maple -- It's on Larry Sagers list of good small trees for Utah. However, a year after we planted it, I read in Michael Kuhn's "Trees of Utah" that it is one of the worst for chlorosis. It sends out new branches each year, but by the next year all of the branches are dead.
2) Japanese Maple (bloodgood) -- Protected, east-side exposure, part shade. The tree did't even make it one year.
3) October Glory Maple -- I knew that it had some problems with chlorosis, but these trees are thriving at homes around us. We've been diligent with the iron treatments. Yet, this spring it's only sending out leaves on the bottom half of the tree.
4) Redbud -- Has struggled from the beginning. Is completely dead. Our neighbor across the street has four that are beautiful.
We have a Tina Crabapple that is thriving and beautiful. We also have a Canyon Maple (graft) that seems to be doing well -- but the fall color is always brown not red. We have a Black Hills Spruce that seems to be barely surviving. We just planted another JM Bloodgood and an Osakazuki JM. My fingers are crossed that they will do well.
Any suggestions? Any suggestions for small trees that might do better in such Alkaline soil? At this point, I'll take any help I can get.
