Planting Asian Jasmine Over Landscape Fabric: Risks to Tree Roots and Watering Tips

A Houston gardener's yard man laid black fabric over tree roots, added a thin layer of topsoil/peat/compost, and planted 4-inch jasmine plugs. She worries about survival and tree health.

If Fabric Was Cut for Planting

Jasmine roots will penetrate the fabric and reach native soil—fine.

If Planted On Top of Fabric

Water management becomes critical; the shallow mix dries and wets differently than subsoil. Over- or underwatering is easy.

Tree Root Danger

Adding more than 1 inch of soil over a tree's root zone can smother it. Roots extend well beyond branch tips. If the new soil covers a large area, the tree may decline over 3–5 years.

Action

Check fabric cuts and soil depth. If depth >1 inch over much of the root zone, remove excess soil immediately.
