What is This?

bllllack rot?

there is a extensive thread about it, search!

should be all good!,it's just some growing spots, should harden of fully in a bit moar time!

That happens to a lot of my cuttings - it think its pretty common. It doesn't usually penetrate into the plant or cause any damage. Keep it dry just to be sure, and if you want to be extra cautious, rub some sulfur powder all over it. You should be able to get this from a nursery, although they don't always seem to have it.

Thanks all
