What this job is
Memorial and River Oaks beds under specimen oaks need a real panel, not plastic edging. The oak will win. Isolation gives the bed a chance and keeps water off the flare — which is also better for the tree.
New landscapes on rebuild lots should have barrier in the original scope. Retrofit is the usual call, after the first season of dead understory.
We will not install a liner that dams a bed into a bathtub against a slab.
Problems that actually show up
- Oaks stealing a bed
- Hedge roots in a walk
- A liner that collapsed after one summer
- Mulch volcano against a trunk
- Beds that will not hold plants under a pecan
- A new landscape on an old root plate
Sequence
- Bed plan What you are keeping, what the tree is, where water should go.
- Trench Deep enough that the oak does not simply dive under a 6-inch edging.
- Panel HDPE, not roll edging.
- Soil and plants after Your landscaper can follow. We can leave the bed empty and clean.
