I had been wondering what the consensus was regarding fleece covered cacti in cold greenhouses, namely to peek or not to peek?. I have tended to leave mine covered given the struggle to separate fleece from spines combined with only being able to see during daylight at weekends due to work times. To...

I thought until now my tealights and terracotta pot in enclosures was working well. The downside of going to work in the dark and returning home in the dark means I only got a good look at everything yesterday after just under two weeks of sub zero temps. I thought that I had kept the enclosure temp...

We'll you did ask, here are some real time photos, 1 degree Centigrade outside right now. The pics show, outside, two inside enclosures and thermometers outside and inside enclosures. I think the pictures are in reverse order

I have a similar dilemma, I have for the first time in about 25 years left almost all of my various cacti in my cold greenhouse. All my Euphorbia etc I've brought into the window ledges. Greenhouse is bubble wrapped and I have two further bubble wrap enclosures inside. Like yourself I was ok until t...

Thanks for the information, I will have to keep an eye out for any signs of nectar production. I'm wondering if it's season specific as I noticed it last year on a large Opuntia in October. This made me bring it out of the greenhouse and overwinter it in the house. I was concerned that the damp and ...

I've seen some of my Opuntias secreting sap bun not any Ferros, this one came like that. I'll try a gentle brushing to see if I can remove the discolouration.
Thanks for the replies.

Any suggestions on dealing with black mould on my Ferocactus horrida v.brevispinus.
I have two, the one on the right seems unaffected.

Thank you for the replies, I am thinking it is a P pringlei. From looking at on line sources there does seem to be quite a variety of spination in terms of colour and size. Combine this with the fact that most pics show mature specimens aka Giant Cardon cactus it's no wonder I was stumped. Thanks ag...

First of all sorry if I've duplicated this request, my first one seems to have disappeared. I grew this from a packet of mixed seeds 15 years ago, an I.d would be appreciated. It has nice spines and red colouring on the new growth. It was not in the best environment for a few years so I think it cou...

These are last month's flowers, uncertain which variety.
