Hoping for some help as to what is wrong with my Verburnum bush..
In the last week its leaves have started to go brown and yellow and get black dusty looking stuff on them. and is slowing creeping to the whole plant. i not sure what it is as all other plants in garden are ok. this is on a boundary where my other one died last year also. a beautiful 10 year old shrub just died.
do they die off with age or is it a disease or weed killer doing it. the bay next door to it is also starting to look unwell..
it is to do with the dry hot summer we have had and lack of rain down here. as even now we not had much since august at all. been dry year down on the Island for us.
would appreciate any help or guidance from you all
thank you in advance
