Hi folks,
I've just acquired a very nice young Trichocereus/Echinopsis terscheckii from The Palm Centre on sale.
It definitely needs repotting, and I want to get it going really well, so I've been nosing around for the "best" soil mix. I've gotten hold of some pumice ("lava rock"), and I've got, I think, the other general ingredients, but a couple of sources recommend including limestone.
Any facts or opinions on this?
Karsty.
