Hello i Think this is Viburnham leaf miner/beetle {shothole}, i come across this quite often, some years are worse than others, you could spray it with Bugclear, its really good i dont like useing sprays etc but in my job sometimes i have to, also i have been vey brutal with this type of Viburnham by cutting them right back in the spring, before long they will throw up lots more folliage, you do not need to dig it out. julien.

Agree with Julien, definitely been attacked by Viburnum Beetle - use an appropriate spray next year, starting probably in April - this pest overwinters as eggs on the branches.

Many thanks, Julien and Bamboo. Ok, I will be patient.

And I thought it was all the fashion to have plants that you could see through ;-s
