In July last year, I mentioned that when Pat Kernan came to do some tree work, I asked him to take out the Viburnum above that had been attacked by an insect. Viburnum beetle was named as the number one pest by the RHS in 2010. I found another photo on the web that shows this.
However, Pat told me about a spray called pyrethrum and this has proved to be a success. The photos below shows lots of new, undamaged growth and lovely flowers.
I shall wait until after flowering before spraying again.
