Having retired last year, moved from Scotland to Bicester, and finding a small greenhouse at my new house, I have started my first cactus collection. Bought a few plants last year. Installed a heater to keep temperature in greenhouse above 5˚C over winter. Some are just starting to flower with this Rebutia wessneriana the first in full bloom. Basic I know to the rest of you but thrilling for me. At least it shows I am doing something right!
