I contacted a tree surgeon and told him I needed woodchip for my back garden. He came round and dropped off what looks like a mountain of leave and wood cuttings - the wood can be seen sparsely. He assured me that this was woodchip. He said you get different grades of woodchip. He told me it wouldn't turn into mud. I'm now scratching my head worrying - I have a mountain in my front garden leaning against my house. Does this look OK?: Any help would be appreciated. I need to decide what to do. I was going to go and buy black membrane to put in garden and then take this and pour over. Thanks.
