You dry them off with the old stalks on, then cut them back to about 2in
ches, then when they are completely dry, store them in newspaper, some peope use that, I keep any old compost from old plant pots dry and store in a cool place, if you havent got a greenhouse or shed, a cold place indoors will do
I would advise only a couple in one pot though, they can grow about 2/3ft tall and quite wide. i only ever put one in a tub and then only in the first year
Out in the garden next year if you can.
You can take cuttings next year for your tubs, when they star shooting.
