Hi Neli
I think your course sand and pine bark is probably a great mix for your semps. A little pearlite will loosen it up even more. That way you will not have rot when it rains every day
They seem to be recovering from their long journey just fine. The garden soil, as you found out will cause some rot. None of us use Peat in semp. mix...ever. It holds way too much water. Instant rot.
I have grown a couple of ice plants (Delosperma ) straight from South Africa.
They didn't do much for the first month but then were fine.
I am very interested to hear how this works for you.
Keep us posted.
