If you take them out of the bags they are going to need constant, almost daily watering and/or spraying.
If you can't do that then leave them in the bags.
It's a bit more fool proof.

Virtually impossible to keep them mark-free in my experience, as are most Echinocereus.
That's not too bad at all.
And they always flower well....

Could be cold damage since winter and rot has now set in.
Last two might be saveable if you take a sharp knife above the rotting parts.

Not me in China unfortunately.

I had a good look but couldn't find that field number on any of my seed lists.
Most canigueralii will give you a flower colour like that. The non applanata kind.
PHA260 and HS71 would be more popular.

Almost like a Rebutia.

I saw that photo on Facebook and made a note of it myself.

There's more experienced people on here than me with field numbers but this may help (or just confuse the issue more).

A handy tool in the battle against smaller bugs. Gives you both hands free.

It’s an eye loupe holder.

Would Killermite kill mealy bugs?
