also lefting few tubercles on a small grafted plant it produces offsets :)

I use this method too. Around 40% of my cut grafts never produce any new offsets. I always leave a turbecle so they can shoot. Do you have this problem too?

yes...some of them are more lucky and some dry up...% of those who produce offsets are quite low in our case too
