If people are looking for a fantastic quality alround multi purpose compost then look out for Premium Horticultures 'Plant & Grow' its supplied in a yellow bag and really is the best ive found.
An old nursery trade supplier, Premium have released this to the general public for afew years now, and it simply is the best. It has good water retention capabilities, is light, fine, and contains no shredded, recycled material at all.
Much better than your rubbish from diy stores and sheds that contains mostly bark chips and green waste.
although not widely available, many stores are beginning to sell it due to high demand. you wont find it on a silly multi buy, and its not dirt cheap at around £6 for 75litres, but we all know its the quality that counts, not the price.
i buy it from a local idependent garden centre in south leicestershire, and i wouldnt change to anything else now.
