Our composts are still much cheaper than you can buy them elsewhere. Jack’s Magic is the same price as last year - £4.50 for a 60L bag or 3 bags for £12.50. Horticultural Grit and Sand is still at £3.50 per bag. Our 150L bags of Strulch are cheaper than 100L bags on sale in a garden centre.  It is reputed to deter slugs and snails which is ideal if you are a dahlia or chrysanthemum grower. In fact, Strulch is primarily a mulch and feed addition to the garden, and therefore will suppress some of the common weeds (though not those with deep roots such as dandelion and burdock).
