    I never have any luck with my alpines outside. Every winter they start to rot in the wet weather. Any suggestions please, or is it best to grow in greenhouse? I've been trying them in old butler sinks.

    Which alpines are you trying to grow? Some can be very tricky. Generally alpines need very good drainage, so a lot of grit in the compost. Does the water run out of the butler sinks freely, you might want to raise them off the ground slightly. Also as they are quite deep containers a layer of hardcore or rocks in the bottom might help.

      Hi Nigel, thanks for that. I have got a layer of hardcore in the bottom and sinks are raised off of floor but I stupidly haven't put any grit in with the soil:noidea:.

      Also, zilly, place a sheet of glass or perspex over them raised 30 cm or so over their heads. Most alpines can cope with cold but not wet weather. Keep sides open so well ventilated but dry over winter :)
