Thanks for the compliments everyone.
Sneaky; yes the ones I have kept for breeding are very nice, when it comes to breeding selection is everything. I am aiming to produce really good quality and it is a basic fact that the selection you make is only as good as the plants you reject. No point in raising thousands of seedlings from substandard parents, if you keep rejecting plants that are just ok then after half a decade or so the plants retained for breeding are really worth going forward with.
Also I have never had any luck with getting roots on degrafted Aztekium but it is worth a try maybe.
Nehme: I don't use anything on the cuts, just dry them upside down inside the house for about a week so the cut surface doesn't go mouldy, then wait a couple of months for them to throw roots.
Maja, funny my wife's friend came round for a few hours and at first she said they were ugly but then after an hour or two she started to notice details and began to think they were nice.
