Over­win­ter­ing canna

Garden News (UK) - - What to do -

I’ve tried my hand at grow­ing canna lily from seed this year, and while they’ve flow­ered nicely, they didn’t get as big as I’d like. Canna can be over­win­tered and that’s my plan to get larger plants next year. Tra­di­tion­ally the plants were left in the soil and mulched well, but my soil will be too wet for this and the plants may rot. I’ve de­cided to dig the young plants up and move them into pots, leav­ing them in the green­house for win­ter. I’ve made sure to check the plants and pots for slugs as I don’t want to in­tro­duce them into the green­house, plus I’ve cov­ered the sur­face of each pot with Slug Gone, a nat­u­ral slug re­pel­lent which should pro­tect the plants. I’m hop­ing that be­ing moved to the green­house will give the canna a month more of growth, so they pro­duce big­ger rhi­zomes once the fo­liage dies back. This should mean more flow­ers next year.
