Q.Barberry bushes drying up
Barberry bushes look as if they are drying up and losing their foliage. I have had 3 barberry bushes for years, all of a sudden they are losing their leaves and look as if they are drying up. It has been very hot the last few weeks. They are on the south side of my home and get full sun. What can or should I do to get them healthy again?
You may need to water to help them through the hot and dry summer days.
2 to 3 inches of hardwood mulch will help with moisture retention.
Watch for insects and treat with Neem Oil if you find any.
