A Memphis tree declining after construction

What might be happening?

MU Extension describes delayed decline after construction where roots were severed or crushed. Tennessee Forestry also lists soil compaction, root damage and mechanical injury among the stresses contributing to oak decline.[5][12]

What to tell the arborist

Tell us when the project happened, where excavation or new paving went, whether soil depth changed, and where vehicles or materials sat. Older ground-level photos can help show the before-and-after conditions.

The next step

Ask an arborist to assess the root zone, tree condition and any safety concern. If retention is appropriate, the written plan can set priorities for root work, soil tests, watering and follow-up. Where another project is planned, involve the arborist before work starts.

What not to assume

Do not dig around major roots or apply fertilizer as a substitute for finding the cause. A soil test may guide feeding, but fertilizer cannot reverse construction damage or solve poor drainage.[3]
