Commercial Groundcover Management

What groundcover is actually for

Groundcover is doing a job that turf cannot do economically: covering ground nobody walks on, with much less water and no mowing.

It works best on slopes too steep to mow, in narrow strips, under trees where turf never establishes, and in the large decorative areas between a parking lot and a boundary.

It is not a low maintenance option. It is a different maintenance option. Established groundcover needs edge control, periodic renovation, and a plan for the bare patches that appear where it fails, and none of that is less work than mowing. It is simply less water and less frequent.

Groundcover goes where you do not want it

Everything that makes groundcover good at covering ground makes it good at covering the ground next to it.

Ivy climbs walls and trees. Trailing rosemary and gazania spill across pavement. Vinca runs under an edge and comes up in the turf. Left alone, all of them cross the boundary within a season or two.

Edge control is therefore the main recurring task, and it wants doing on a cycle rather than when somebody notices. A groundcover bed cut back to its edge three or four times a year stays a bed. One cut back annually is a reclamation project each time.

The specific case worth naming is ivy on trees. It climbs, adds weight and wind resistance to the canopy, and hides trunk defects from anyone assessing the tree. It should be cut at the base of every trunk as routine.

When groundcover needs renovating

Groundcover does not last forever. Most plantings thin out, build up woody thatch underneath, and develop bare centres after eight to twelve years.

Patching bare spots into an old planting rarely works, because the new plants compete with an established root mass and lose.

The usual answer is renovation in sections. Cut an area back hard, or remove and replant it, and let it fill while the rest of the bed carries the appearance. Doing the whole area at once leaves a large bare patch for a full season.

Where a groundcover keeps failing in the same spot, the cause is usually irrigation coverage or drainage rather than the plant. Replanting into the same conditions produces the same result.

1. Identify whether the problem is age or a site condition
2. Fix irrigation coverage and drainage before replanting anything
3. Renovate in sections rather than all at once
4. Cut back hard where the species responds, replant where it does not
5. Mulch the renovated area until it fills in
