Guy Posted July 14, 2019 Report Share Posted July 14, 2019 (edited) My new(ish) greenhouse has some space for a few cacti. The greenhouse is frost free, with a heater keeping the temperature to above 4°C in the winter. The cacti in my local gardening centre all say 'keep above 10°C', when they say anything! What can you suggest, please? Thanks. Guy Edited July 14, 2019 by Guy Quote Link to comment Share on other sites More sharing options...
S Krelbourn Posted July 14, 2019 Report Share Posted July 14, 2019 I keep a few echinopsis in my greenhouse over the winter, I keep them dry and it drops below freezing on occasion and they have been ok for the last few years, in fact they flower better than the ones I keep indoors.

Dunc Posted July 15, 2019 Report Share Posted July 15, 2019 Many cacti will survive sub-zero as long as they are completely bone dry. I overwinter a few in my greenhouse and I only keep it frost free - zero deg C if I can, once or twice minus a few! Quote Link to comment Share on other sites More sharing options...

Guy Posted July 15, 2019 Author Report Share Posted July 15, 2019 Thanks all. Very much appreciated. Seems like cacti are hardier than they first seem! Off down to the garden centre in the next few days to pick a few up. Thanks again. Guy Quote Link to comment Share on other sites More sharing options...
