Cana Lillies -- to lift or not to lift
I planted three new cana lillies this year in a newly designed hot bed. They have grown really well, now about 1 metre tall and have all flowered well. The bed is in a corner of the garden, south facing, with walls on two sides. The soil is also very free draining. My question is would it be best to lift and store them in the greenhouse, or cover with mulch and leave where they are? The plants are surrounded by day lillies, dahlias, kaffir lillies, and many other plants which I intend to leave in situ and mulch.
