Eco Tree & Shrub compost

Peat-free soil improver, perfect for giving acid-loving trees and shrubs a boost

Take your trees to new heights with our Tree & Shrub soil improver. Made specifically for plants that need an acid environment, the added phosphoric acid helps to establish young trees and shrubs by lowering the soil’s natural pH value. 

Locally produced by composting organic offcuts from Dorset gardens, the 12 week maturation process produces a sustainable and high quality, peat-free compost. 

Screened to 10mm and with added phosphoric acid, your acid-loving trees and shrubs will receive a welcome boost. 

Spread Tree & Shrub Soil Improver through the soil around your trees and shrubs for optimum results.
