Hi There

Have brought surfina plugs on in my heated greenhouse since March and they are now in full bloom but straggly. Is it ok to cut them back? or will it do them in?

It will do no harm to cut them back. They will re-shoot from the leaf nodes and make bushier plants in no time

I bought some petunia plug plants and for the first time nipped the leading shoot off to make them bushier.
