How & when erisimum & scabious cuttings?
I'm not very experienced wtih cuttings, could anyone tell me when & describe how to take them from erisimum bowles mauve & scabious butterfly blue?
They're both meant to be hardy but I don't want to take any chances & would like more of them.
Should I deadhead the stalk off both plants too, to keep them producing more, or should I leave them on & is it worth collecting seed?
Many thanks for any help.
