Topiary Dying

Question

I purchased a topiary for the front flower bed that receives full sun about a year ago. The topiary started to show brown leaves on the upper levels, which is now traveling further down the plant. I have tried dusting it with pesticides. I’ve fertilized it, and nothing seems to be working. What should I do?

Answer 1

Need more information.
What plant is it?
How long after purchase did you notice symptoms?
Is it in a container or planted into the ground?
How much and how often does it get water?
Have you seen pests?
Have you contacted the seller?
