Box Caterpillar infestation
As some of you know I volunteer at Capel Manor Gardens in Enfield. Last week I "discovered" an infestation of Box caterpillar in one of the areas I was working on. At first it looked a bit like box blight with brown patches but close inspection showed the real culprits! We sprayed the plants straight away. This week the senior gardener I work with told me that one of the section heads had checked other areas & found other infestations so they plan to spray ALL the box plants in the various gardens (quite an undertaking). Later in the day a visitor to the gardens spoke to us she had some samples of damaged stems from her garden & we were able to show her it was the same thing. She was actually relieved it wasn't blight. Apparently the last big outbreak was 2 years ago.
You have been warned keep vigilant!!
In case anyone is not sure what they look like here we are. They hide in a cocoon of silk so not always that easy to see. You see the munched leaves first!
