UPDATE April 21TH 2021

BOX TREE CATERPILLER

With the arrival of spring weather, the Boxwood caterpillars begin to awaken from their winter sleep and start causing damage again. A treatment is recommended from now on. In gardens, you should preferably use products based on spinosad (Conserve Garden), which are allowed in organic cultivation. In other European countries there are other biological agents against caterpillars available.

TIP: Spray preferably in the evening to spare the beneficial insects. Only the green parts of the plant need to be treated.
