That does make so much sense, dammit well it's my first go at overwintering so I'll know not to prune if I overwinter one again, I quite like growing from seed though, I get excited when they start to sprout, it took so long this year as we had a very cold start to spring
They'll be less pests now I've pruned it right back though, the only pests I had this year was them tiny little flys that love the soil, I put some small yellow fly traps made for plants on thete that helped alot, other years I had allsorts of bugs and small green caterpillars, that creeped me out so I put them plants outside and didn't grow anymore for a few years, till this year actually if it happened again I'd of quit as I hate bugs lol, the flys was bad enough lol
A little tip for controlling fungus gnats is to put a thin layer of sand/grit on top of the soil, and to water from beneath. They don't like dry soil so will generally avoid a pot treated like that.
FWIW 90% of the time they're completely harmless, especially if you add a little fresh biomatter/compost to the soil every year for them to feed on - that way they won't want to eat the plant roots.
