Sometimes seed that's sown doesn't germinate - how long should you keep the pot? With Opuntias I routinely keep for a few years, it often takes more than 1 year for germination. I don't usually keep other failed germination pots. Maybe I should. This Crassula coccinea was the sole seed to germinate when sown last year.

If there had been good germination, it would probably have been transplanted by now. Recently I noticed something else in the pot.

It's taken its time, but the overall germination rate has now doubled. Bit of catching up to do with its older sibling.

I find this happens often with Lophophoras.
