Can anyone tell me what happened to my geraniums? I planted up several pots of geraniums this summer and they were looking great. Then they suddenly started looking a bit miserable. On further investigation, I noticed the leaves had been eaten away and only stalks remained. There were tiny black grubs on the leaves and a couple of green caterpillers! My next door neighbour has cabbages in his garden, so would this be the problem? I have seen several white cabbage butterflies around, and thought maybe they were laying their eggs on my geraniums too. Any advice on this please?
