The dreaded vine weevil!
Thinking that the weather had lifted the polyanthus from several pots, I went to firm them in, only to find that they had no roots left. I can see the vine weevil grubs which devoured them, grrrrr. The plants have duly been binned . I'm wondering whether the winter will kill off the grubs, or should I drench the pots with Provado now? I usually skim the compost off the top of the pots and put the compost on the borders in the Spring and then top up the pots with fresh compost. Help please! There does seem to be quite a lot of the horrible little blighters. I don't have room to empty the pots out to leave a feast for the birds!
