Supporting flowers grown for cutting
I've got an allotment plot and I'm growing a selection of flowers for cutting: cosmos, gallardia, nicotiana, nigella, zinnia, cleome and Chrysanths (sorry, went mad in March when seeds first appeared in shops!). At the moment, they're in the cold frame, deciding if Spring has arrived. I've grown them in modules for ease of planting out. When I do, should I support them? I'm a little exposed on the site as with most allotments. Also, if I want cut flowers, how do I treat cosmos re: pinching out?
