Tree Soil Technical Info
Heicom tree soil is a blend of carefully selected and highly graded sand, organics and a slow release fertilizer.
Unlike some alternative products, tree soil does not contain green waste which is still decomposing and can become anaerobic very quickly, sometimes leading to surface instability.
All compost used is supplied by a WRAP approved supplier in a fully composted condition.
