Update September 20th 2019

The caterpillars of the second generation are gradually emerging. These caterpillars are small and have done little damage. When it gets colder, they spin in and hibernate. It is these caterpillars that in April, when they are fully grown, cause heavy damage.

A good treatment, with a registered caterpillar remedy, can prevent much damage in the spring. Products with a slightly longer effect based on spinosad, permitted in organic farming, are preferable. Gardeners have a wider range of safe products.
