Tree Health & Maintenance
Disease diagnosis, deep-root fertilisation, borer treatment and ongoing care for high-value trees.
About our tree health & maintenance service
Established Gauteng trees — heritage jacarandas, mature oaks, plane trees, yellowwoods — are hard to replace. We focus on keeping them alive: identifying stress causes (drought, borer, root compaction, fungal infection) and treating them before removal is the only option.
Common diagnoses on our books: polyphagous shot-hole borer in plane and oak, cypress canker, leaf miners on jacarandas, and root-girdling on landscape trees that were planted too deep.
When you need this service
- Sudden leaf drop or canopy thinning
- Bark beetle holes, sap weeping, fungal brackets
- Yellowing or stunted growth on a previously healthy tree
- Newly planted tree struggling
- Heritage tree you want to preserve indefinitely

Tree Health & Maintenance — common questions
Can you save a dying tree?
Sometimes. Early intervention works; trees with >60% canopy loss or trunk decay usually can't be saved structurally.
What's deep-root feeding?
Pressure-injected liquid fertiliser and biostimulants to the root zone — past the lawn that competes with the tree.
Is borer treatable?
PSHB has no cure, but we can slow it and keep low-infestation trees productive for years with monitoring.
