Have had horrible experiences with compost too - the first few years peat free came on the market it was good, and we used it quite happily. Then everyone jumped on the bandwagon and most are awful. I have had very bad Westlands, so glad that Gold1locks has found good stuff. The best I have found so far is B&Q's multi purpose, whih sadly is with some peat, but even that needs watching for sticks and lumps. I sieved it for seedlings as the small bag of seed compost I bought was so rough that very few seeds could have germinated in it. Hope the broad beans will manage.
Last year I bought a tonne of bark chippings to cover the ground in our fruit cage, and some of this years compost looks almost exactly the same!
