Aquilegia stripped bare
I have an infestation in my Aquilegia patch. The leaves are gone and
what remains are the stalks and a few tough bits. It would seem that one of the Sawfly family has paid me a visit. I have had picked 3 caterpillars from the plants (about 30 plants) but I suspect there are many more, but they are just so difficult to spot. I read that Aquilegias can be cut down to the ground in preparation for the winter and will grow new leaves etc in the spring. Would it be worth trimming these plants back to ground level, there by removing the food supply and hopefully eliminating the caterpillars? These are new plants raised from seeds this year so I would not class them as 'established'. Look forward to reading any advice. |

No. You'll simply be doing what the saw fly larvae might do for you anyway ;-) And on the bright side, they may not eat it all, so the leaves that are left will continue to make food for the plant for a few weeks longer until they die back naturally. Removing the leaves won't have any effect on whether or not you'll get sawfly next year. They'll come from wherever they came from this year. -- Kay "Do not insult the crocodile until you have crossed the river" |
