My mouth 😃
Probably worth potting on once into a slightly bigger pot, the extra food should encourage some new leaf growth, but in my experience they flower and then senesce.
Don’t split them, the added stress will encourage flowering.
Might be a factor of living well north of the equator and shorter days (Scotland), but overwintering is not something that’s possible for us. It’s an annual plant: grow, flower, seed, die.
Better to sow more seed or buy another supermarket pot and pot in on straight away so it never gets a chance to be stressed by lack of nutrients.
The old ice cream brain freeze feeling, only it doesn’t stop till you stop cycling…
I get by with a snood under my helmet pulled down to my eyebrows and another from below pulled up over my nose. But then I’ve not cycled in lower than -3C, I think.
Maybe you need a full face helmet and goggles? Money aside…
