Hi all can someone help me with my Thuja trees? As you can see from the photos they don't look good. I am not sure if this is normal or if they have a bug - and if so how to get rid. I had 50 similar trees a year a go and they were all replaced, I don't want the current ones to go the same way.
Please someone one help me, what is wrong and how can I make them better. Should I remove the yellowing leaves and spray. Trouble is once I spray it rains!!
thank you ????
