at the risk of feeling really daft, having had cannas for 2 years now, i'm wondering whether i'm doing the best for them.
they come into the greenhouse in pots to overwinter.
i cut down the stalk after all the leaves are finished, and just let the compost dry out slightly.
new growth sprouts from along the tuber in spring.
is this how others care for theirs? could i do better? my cannas never quite seem .....luxuriant, which is the effect i want.
what would happen if i left the stalk? would it just go squishy and need cutting down anyway?
help please!!!!!!
