Frost tolerant Trichocereus?

Recommended Posts

I am moving to a new place next week(will post pics in  a week or so) where i plan to make a succulent and cacti garden(with idea i may also breed for seeds and make cuttings for sale around some of the local markets) I intend to erect a few hot/glass houses simulating different environment but also intend to extend the garden there(someone has spent a longggggg time creating it amid nothing but farm pastures) with a cacti and succulent area. The issue here is the frost during winter time, i really don't know much about cacti growing but have heard many cacti will just turn to mush under these conditions so aside from general frost tolerant cacti and succulent i was wondering if people here may have some experience with what may be some frost resistant strains or crosses of Trichocereus?

From what I've read T. Terschekii is supposed to be an exceptionally frost tolerant trichocereus species.

Hey Zool, im not much of a expert but was of the understanding the knuthianus dont mind a bit of chill. We get 6+ or so ripping frost down here,  I was intending in putting some trichs into a raised bed and covering with a frost cloth.

we get some frosts here in melb (usually a few mornings touching 0 or so), my plants have never had a problem. usually plants will turn to mush if you have them too wet and you should be keeping them relatively dry during winter any way (and preferably unnder some cover). but we're not as bad as tas or NZ so YMMV

It regularly gets below freezing where I live, and it's not an issue at all for trichocereus. They're tough.
