I'm running the best restaurant in town!
Everything in my new garden is being attacked with leaf rolling caterpillars - and I do mean everything. I've just found both caterpillars and the adults in my Crassula ovata or Jade plant. It is quite young, about 30cm high and was a new plant last year. The adults are small insects and jump when you try to catch them. I am amazed that the caterpillars can sew together the tough leaves of the Crassula. I have spent hours unrolling leaves to remove caterpillars and have removed many of the growing tips of plants where I see the evidence of their presence. Has anyone any suggestions as to what I can do to save my plants? One suggestion has been to remove the top few inches of soil to prevent them from over wintering as pupae but that will be the last resort since I have so much ground cover. If there is one, would a systemic insecticide work? I loathe the idea of chemicals but am getting desperate. I've already reduced the flowering potential for both now and next year. The second flush of roses is ruined, which is heartbreaking. I've never had them before and suspect that they arrived in the pots of plants last autumn.
