Great products, Great service.

Incredibly fast service, great micronised product, The good Dr was very honest and although hadn't changed a price on the website, informed me and refunded me promptly before dispatch. Probably the best organic gardening shop in the UK both online or otherwise. Very little or no plastic in the parcels i have received from DF gives me no reason not to throw up a 5 star review.
