Very nice collection i have loads and loads of opuntia prickly pear a few robusta and i have just taken a load of cuttings of opuntia tuna which i got an id from your pics what do you do with them over the winter as last year i put them in my tort room but as i have propagated soo many this year i have no idea where to put them maybe i should have thought about that one before i did it
I do have a greenhouse would they overwinter in there with no heat
