Anyone any good at cannas or ginger lilies?

Just giving it a bump.

Been growing nice variegated cannas for years but they never flower. In 10" pots and overwatered in cool green house.

Ginger needs to build up to a rhizome. Once it gets going it'll be a triffid. My Hedychium gardnerianum have distorted their pots and are overflowing!

Canna need rich soil - feed, lots of compost etc. To get them to flower they need lots of sun. Do you keep them going over winter or induce dormancy? I make mine go dormant & in march repot them with lots of compost & feed indoors about 10-15 degrees c, then into unheated greenhouse about middle of April, then harden off may.

I keep the cannas at about 4 deg over winter. They do die back.
Never repotted, will do next year. Have been giving them tomato fertiliser to try to get them to flower.

I sometimes repot back into the same pot, just refreshing soil around to make sure there's plenty of nutrients (like you would a pot grown tree). Mine got so big last year I split it into 4 - will see if they flower this year. I'm planning on taking mine out of pots & putting in the ground this year if I ever get round to it. At the moment they've made it as far as outside the greenhouse door. ....

Mine grow on at 10-15 as that's the temp of an unheated room I have, & greenhouse in quite an exposed spot so gets just that bit too cold in winter.

Never grown gingers though.

Just had a quick look, first flower bud on one of the four now forming - yay! Didn't flower last year as kept it in to shady a spot. I knew this, & could have moved easily as in a pot but didn't for some reason.....

These are my triffid gingers. There's a few years growth there!

Cool - they look like something growing on the bottom of an ocean!

I've finally managed to upload pics by more than pure luck

so here's a pic of the one canna which is flowering. Quite cool, bought it as a green leaved, yellow flowered un-named reduced half dead tiny plant from tesco. Turns out I think it must be canna 'cleopatra' as it changes flower colour (this year yellow & red with spots) & leaf colour - sometimes green, sometimes variegated, sometimes dark.
