Sloping garden ideas

A slope becomes an asset the moment you stop trying to flatten it. The real decision is how much to terrace and how much to plant.

Getting it right

Terracing is the expensive option — any retaining wall over about a metre needs engineering, drainage behind it and proper foundations — so terrace only where you genuinely need level ground and plant the rest. Get the steps right: a comfortable outdoor step is a 150 mm rise with a 350–400 mm tread, far shallower than indoors, with a landing every ten. Then cover the remaining slope with deep-rooting groundcover planted through jute matting until it knits together.
