Ground cover for a dry Spanish garden

en

Ground-cover plants can cool the soil, soften paths and occupy gaps where weeds would otherwise establish. They are not maintenance-free and they are not all substitutes for a lawn. The useful question is what a particular patch must tolerate: foot traffic, salt, shade, slope or reflected heat.

Match habit to place

Creeping thyme and prostrate rosemary suit sunny, well-drained ground, although woody stems do not enjoy constant trampling. Santolina forms low mounds rather than a close carpet. A restrained succulent may cover a hot bank but some ice plants spread beyond gardens and are invasive on Mediterranean coasts. Check the exact species before planting.

Dense shade beneath a wall or tree needs a different palette from a gravel slope. Soil which remains wet around the crown can kill plants described as drought-tolerant. Improve drainage where possible rather than hiding the problem under more plants.

Prepare for establishment

Remove perennial weeds before planting and loosen compacted ground. Space plants for their mature spread, leaving stepping points for maintenance. Water thoroughly through establishment, then lengthen the interval between watering as roots develop. A thin mulch suppresses seedlings and limits evaporation without burying crowns.

Keep a tapestry under control

  • Cut back growth before it blocks drains, covers lights or narrows paths.
  • Lift self-rooted stems which cross into wild ground or a neighbour's plot.
  • Replace failures with a plant suited to the microclimate instead of increasing water to the whole bed.
  • Retain deliberate bare gravel and stones as access, not as signs of an unfinished scheme.

A mixed low layer is often more resilient than one species from boundary to boundary. Repeating three or four compatible plants produces unity while reducing the chance that one pest, frost or drainage problem removes the entire cover.
