Last year I bought a small bag of Westland Multi Purpose with added John Innes & it was the best I'd ever tried, really fine & no large bits at all.
This year I bought J Arthur Bowers MP with added JI, 5 for £15 as it came in 35 litre bags which I thought I'd be handle more easily. They are so wet they weigh more than some of the 60 litre ones I've had in the past! I was also swayed by the fact it stated Which best buy compost 2012....
As other say, it is full of fairly large twigs & has a really rough texture. I'm not happy as I bought it to pot on seedlings & then fill all my greenhouse pots for tomatoes, chillis & my outdoor pots for everything else.
As for taking compost back, I agree people should, to help solve the problem of rubbish compost being sold.. It's often so hard to do though if you need someone to help load the car up at both ends etc. I guess suppliers know this, hence why the continue to produce/sell it. It would be so much better if only decent stuff was sold in the first place.
So what to swap it for if I do take it back. We seem to have one good & one bad review about the Westland, are you both talking about the MP with added JI? Nothing worse than going to all that effort of swapping & getting home with one worst still!
