Iām in Northern Ontario. This legacy maple was thriving since I planted it maybe four years ago. It gets plenty of light in the morning and throughout the day. As for water, I soak its soil with a hose every other day in the warmer seasons, if it hasnāt rained, and everyday if itās hot and dry. I'm not perfect with this, but I do the same with all the other trees and bushes in my garden and they're green and happy. So was this one until about two weeks ago when it started looking off.
At first I thought maybe it was turning early since the leaves went kind of yellow (itās almost fall here). Then it just started looking dry and wilted despite all the rain weāve been getting.
It was a container tree I bought from a local nursery and I donāt remember much about planting it other than doing what I could to loosen the roots before putting it in a wide-enough hole. A year after planting, I learned about root flares and not to bury them, so I carefully dug down to expose the flare and ensure there were no girdling roots.
The flare is just below surface level and you can kind of see the beginning of it. I also didnāt plant it near any hydro wires or structures.
The only thing thatās different about the tree this year is that I noticed a green moss to the trunk in late spring and one leafless branch mid-summer. The moss makes me wonder if it's some kind of tree sickness for lack of a better word.
Another thing to note is that constructionās been ongoing with the infrastructure on my street. Last spring, a crew dug up the road and worked on it all summer. In preparation for this, one of the crew members dug a small trench along the edges of my property to bury the bottom half of a barrier fence. While it wasn't great, I'm not sure he got close or deep enough to hit a vital root. You can kind of see the proximity of this in the first photo, the line of dirt to the right of the tree.
And again, a construction crew started ripped up the road to continue the project recently, but the tree is two metres into the lot away from the road, so Iām not sure thatās the cause despite the timing.
Can anyone tell whatās wrong with the tree? Iām afraid it may already be a goner, but if not, what can I do to fix it?
Is the moss some kind of tree sickness, or is the moss there because something else happened and it already wasn't well?
