I know I am getting in early here as summer has just started but..........

I have pots in the garden some being plastic. They contain a mix of
geranium/pelagonium, nemesia amelie (beautiful plant specially againt the
silver leafed dianthus and red pelagonium/geranium) ,verbena,
dianthus/carnation, lilys, osteospermums, lithodora (heavenly blue),
marguerites, ganzia's.

I know you are lucky if pelagonium survive the winter (one of mine did from
six) and one osterpermum survived from four, nemesia, survived fine as did
the Lilys. Verbena died, ganzia's died, the rest of the above plant I have
are new this year.

I have a path next to the house I can keep them on, a dark garage or a shady
wendy house or sorry summer house. There are 23 of them so quite a few to
protect.

I don't really know what cloches and poly tunnels are used for. I live on
the south coast, Felpham, about 150 yards from the sea. I hope thats all
you need to know to possibly answer my question, which is, if you haven't
already gathered from the subject, 'How do I protect these from frost.'

Thanks
