I have a whole drift of perennial blue geraniums in one of my flower beds and have noticed for a couple of years now that they are laced with holes - and they have stopped flowering. Upon inspection there are leech like tiny caterpillars on the backs of the leaves - any ideas apart from cutting them all back - as to how to eradicate the blighters. Thanks




Try spraying with Bug Clear on the underside of the leaves.

Good idea but the leaves are small and there are thousands of them - leaves and caterpillars.

I have pulled them all out, I couldn't bear the thought of the critters invading other plants in the garden.

Oh dear, that sounds a bit drastic!

What a shame you went to such drastic measures. I had the same prob on one of my geraniums, I cut the lot down to the ground and burnt the blighters..... very satisfying. the geranium has since regrown and may well be in flower in time for open garden.

I've got loads more all over the garden, it was just this one patch that was being eaten.
