This beautiful tree in our backyard has exposed roots. Water collects around it during rainfall. Is there a way to fill these areas around the tree without harming the tree? Dirt? Mulch?
Is this still survivable or would I have to cut it down? Leaves looks fine but the bark looks in pretty bad shape
Title: Mature rain tree in South Africa rapidly losing its canopy — root damage, disease, soil compaction or possible poisoning?
Hi everyone,
I’m looking for advice from professional arborists or anyone experienced in diagnosing declining mature trees.
I have a large, mature rain tree located in Durban, South Africa (subtropical climate).
Background:
In April 2025, the tree appeared healthy, with a beautiful, dense green canopy.
Over the following months, I noticed a gradual deterioration. By June and July 2026, the canopy had become noticeably thinner.
Now, in October 2026, the tree has lost a substantial amount of its foliage. The remaining leaves appear yellowish, and leaves continue to fall.
Some important observations:
The deterioration has been progressive over several months rather than happening suddenly.
There has been construction activity near the tree.
Construction materials and other items have been placed on the ground around the tree, potentially compacting the soil and affecting the root system.
The tree has experienced significant canopy thinning and yellowing leaves.
I’m also concerned about the possibility of chemical damage or deliberate poisoning, although I have no evidence that this has occurred.
My questions:
Based on the photographs, what do you think is the most likely cause of the deterioration?
Could soil compaction from construction materials damage the roots enough to cause this level of canopy loss?
Does this look more like root stress, disease, nutrient deficiency or chemical damage?
Are there any visible signs that would suggest herbicide damage or poisoning?
Is the tree likely to recover, or could it be dying?
What immediate steps should I take to improve its chances of survival?
Would soil testing or an inspection by a qualified arborist help identify the cause?
I’ve attached photographs showing the tree’s condition over time:
Photo 1: Today 11 oct 2026 — current condition
Photo 2: June 2025 — Full canopy looks healthy
Photo 3 & 4 - some time in Sep 2024
This is a beautiful mature tree, and I would really like to save it before the damage becomes irreversible.
Any professional opinions or suggestions would be greatly appreciated.
Thank you!
Hi, I’m in north San Antonio with about 10 Texas live oaks in my backyard. Our trees are dropping more leaves than usual this early in autumn and we’re concerned about disease plaguing them. Is anyone familiar with Live Oak ailments and able to provide advice? I will try to provide a photo of the leaves if I can figure out how to work Reddit
Anyone have any luck/experience stratifying and growing beech from seed?
Hello, I am new to the subbreddit and not actually sure where to ask this question as it is not technically about tree law, but I work in a dealership and we have a tree growing in the middle of the parking lot and is surrounded by pavement and the company is planning on re-paving the entire lot by next year, so I wanted to know how difficult it would be to move a tree and re-plant it somewhere safe and is it possible to do it on my own or would I require professional help any advise would be helpful
Saw this today on my smallish magnolia. Is this scale? If so, how do I treat?
