Last year I bought a Datura which is currently overwintering in the
spare bedroom. Come May/June it's getting re-potted then it's going
outside. I've got a couple of questions about what to do with it
then.

1. Should I prune it? It's about three feet high with a few leaves at
the top ATM.

2. What compost should I use? J.I. # 3 perhaps?

Thanks for any help,

Andy
