Taking sedum leaf cuttings
A couple of weeks ago on GW they showed how to take sedum leaf cuttings - this was as simple as cutting a leaf, sticking it into a gritty compost and waiting. I took a dozen leaves off a few plants but all but 2 sort of collapsed in the seed tray without creating a new plant. (The 2 remaining leaves are still sat in the compost but haven't produced anything yet..... ) I didn't overwater so I wondered what went wrong and how to ensure a better result. Thanks for any advice.
