Cover sewer treatment system?

Sarah Cullinan asked 14 years ago

We have a large septic tank (with associated scent) covered by a concrete slab about 3 foot by 5 foot in the garden. I want to plant around it using scented plants/herbs/shrubs trees. Do you have any suggestions.? I am hoping to stick to the colours brown/orange/yellow in my 1/2 acre new garden

To plant around a septic tank, or other obstacle, will draw more attention to it, unless it can be incorporated into a wider sweep of planting. There is no problem planting near a septic tank but trees and large shrubs should not be planted over the associated percolation area as the roots can cause blockages.

Plants will not effectively combat the smell of a septic tank, but this problem usually settles down in time. The problem is a technical one to do with the function of the tank and how it is vented and where it is located.

You will find lots of suggestions of plants of various kinds in our Plant finder:
