I would'nt risk it C. I grow all my cacti in a greenhouse but bring them into the conservatory every year ( abit of a pain ) but better than losing them to the freeze. Some Opuntia & Agave types take a freeze but it's the length of the freeze we get in the UK that damages. By coincidence I too have bought my mini greenhouse into the kitchen temporarily while I sort out a better alternative to the epiphyllum collection ( it's currently blocking the mirror which has inconvenienced my wife :-) LOL your in good company as there are loads of us currently stepping over our beloved plants rescued from the cold!!

Thanks Bambi, funny mine is blocking mirror too,much to my

4 daughters annoyance.

I have insulated shed my kids use i can move it there maybe

Thanks for help

hi Carmel..if you do have to move them into the shed..make sure they got good light and when its freezing outside throw a blanket over the top of the whole thing at night...

The main goal, Carmel, is to keep the cacti from going much below 4 deg. C (39 deg. F), while letting them have enough light to stay healthy. If it gets below that in the shed or with the mini-greenhouse outside--hard to guess without knowing where you are--it will mean bad news for many cacti, especially young seedlings. I suspect the other plants will be even less enthused!
