Q.Delosperma grown in cool greenhouse over winter
Can Delosperma be grown in a cool greenhouse over the winter? I live in Saskatchewan, Canada – I have a sun room off the southwest side of the house that stays quite cool in the winter…..three varieties in 5″ pots now. Will they winter over with minimal watering?
Yes, you should be able to winter them over.
Keep in mind that the pots are quite small and they may need a bit of protection to keep the root temperatures more constant through the dormant period.
Changing temperatures can cause the to die.
