Foundation Planting Bed Height: Soil Against Brick Walls

Homeowner with new brick home (built 1999) questions adding 4 inches of soil against foundation for planting beds versus removing clay/rock. Relatives warn of termite risks.

Termite Barrier Reality

Concern is valid: Soil above termite treatment zone bridges the barrier. Check with landscape designer or termite company for barrier depth. Typically 2–4 inches added soil is safe if below barrier.

Recommended No-Dig Bed Method

1. Spray glyphosate on lawn area 1–2 weeks before planting
2. No need to remove dead grass
3. Create berms (raised mounds) with imported topsoil
4. Plant ornamentals into berms
5. Lay 2–3 layers newspaper (biodegradable weed barrier)
6. Apply 2–4 inches mulch
7. Monthly: spot-spray weeds, hand-pull large ones

Planting Technique

Amend planting holes only with compost/peat/topsoil mix. Fertilize with Espoma products (Holly-tone for evergreens) broadcast over bed after planting.

Key Principle

Berms elevate roots above poor clay without raising grade against foundation. Newspaper suppresses weeds for one season while plants establish.
