How Cold Can They Go?
I am a newbie going into uncharted territory- winter!
I have quickly amassed 50 small cactus in pots. I have lots of Mammalaria, lots of Matucana, some of these: Lemairocereus, Lobivia, Parodia, Rebutia, Gymnocalcium, Notocactus, Echinocereus,Ferocactus, Astrophytum, Turbinicarpus, Sulcorebutia, and others.
What is safely the minimum outside temperature that I can expose them to?
Has it been too cold for my Lemairocereus because it is turning red? Will it turn back to green?
When should I water them? The last time was in late September. I LOVE them so much and I do not want to kill them. Please tell me how to deal with winter.
I live in Athens, GA where we sometimes have warm days in winter, 60-70, followed by cold nights.
Is it good to take them outside as much as possible when temperatures allow? I know that taking them outside will accelerate their biological processes and I may need to water more. How do I adjust for outside time?
Are there any cactus lovers in the south who can advise me of how to deal with our special climate? This is so not Arizona.
I would appreciate any guidance.
