Q.Brown leaves on barberry shrub
My lime colored barberry shrubs leaves are turning brown. These were planted last year. I did spay a product with Neem on them but no change.
Will try to post a picture of one of them.

This results from damage to the roots from severely fluctuating moisture (repeated drying out and getting waterlogged). Spread 2 to 4 inches of organic mulch on the soil over the roots to avoid this problem. Be sure and plant barberries in soil that has sufficient organic matter in it that it drains well, yet retains moisture.
