Hi Verdun, Robbie was also asking about runner beans - ericaceous won't do runners any good at all, hence the advice about planting near the fence and using canes!
Once you start this gardening lark, you find yourself being given all manner of strange things. I've given away plug plants, jiffy pellets, and copper tape to name but a few. I've also gone skip diving (with owners' permission) for plant pots and planters!
You're right about the compost, with blueberries, cranberries, azeleas, rhododendrons etc needing proper ericaceous stuff. Are there any other berries that need ericaceous? I know strawberries and rasperries don't, what about all varieies of currant - asking as I've recently bought a blackcurrant and it looks as it's doing OK in ordinary clover MPC.
