How far from the foundation should I plant?

Keep woody plants at least three feet from the wall and size them for mature width, not nursery-pot width. Roots and trapped moisture cause most foundation planting damage.

Can foundation plantings lower cooling costs?

Yes. Shading the west and south walls and the AC condenser can cut summer cooling load measurably without blocking winter sun if you use deciduous species.

Which plants keep pests away from the house?

No plant is a force field, but aromatic perennials in the ring plus a clean, mulch-free two-foot band against the wall makes the perimeter far less attractive to rodents and ants.

Intentional Planting

The Foundation Ring: Planting the First Ten Feet Around Your House

The ground touching your foundation controls moisture, pest pressure and summer cooling load. Most of it is planted exactly wrong.

Herb and perennial planting along a stone house foundation in summer

The standard American foundation planting — a row of yews jammed against the siding over a bed of dyed mulch — traps moisture, hides entry points and hands rodents a covered corridor to your sill plate.

Rebuilt properly, that same ring drains water away, cuts west-facing summer heat and pushes pest pressure outward instead of inward.

Materials

Gravel or coarse mulch
Perennial herbs (lavender, rosemary, thyme)
Deciduous shrubs for the west side
Landscape fabric-free compost

Tools

Spade
Rake
Level
Loppers

Estimated cost: $150. Difficulty: Beginner.

1.Clear an 18-inch bare strip against the wall

Nothing planted, nothing mulched, gravel only. This dry strip lets the siding breathe, exposes any pest highway to view, and stops splash-back from rotting your sill.

2.Fix the grade before planting anything

You want at least six inches of fall in the first ten feet, away from the house. Every wet basement I have looked at on a homestead started as a grading problem, not a foundation problem.

3.Plant aromatics in the second ring

From 18 inches out, lavender, rosemary, thyme, catmint and yarrow. They are drought-tolerant against a hot wall, they bring in pollinators and predatory wasps, and deer walk past them.

4.Put deciduous shade only on the west

A deciduous shrub or small tree eight feet off the west wall drops afternoon heat substantially in August and lets the sun back in come January. Keep evergreens away from walls entirely — they hold moisture year-round.
