Soil Improvers & Amendments

Get the structure of your growing mix right with our range of soil improvers and amendments. Choose from horticultural perlite, vermiculite, clay pebbles, volcanic pumice and coco coir, in sizes from small houseplant bags to large sacks for allotments and growers. Mix them into multi-purpose compost to change how it drains, holds water and lets air reach the roots. Many lines carry our own UK Grow and Potting Pantry brands. Order by 3pm for next day delivery.
