Butterfly bush problem

Asked September 1, 2015, 11:17 AM EDT

My two butterfly bushes are about 2 years old. They were both in pots and this past fall I replanted them and both had grown. They have a lot of yellow leaves and curling endings. My garden is suffering this summer!

In general butterfly bush is adaptable to a wide variety of conditions. However, they require well draining soil or can be susceptible to root rots. They also benefit from they benefit from a 2- to 3-inch layer of organic mulch. Once established they are fairly drought tolerant. Make sure the soil is well drained.
They can also be susceptible to spider mites, a sucking insect pest. Look at our website for photos. http://extension.umd.edu/hgic/spider-mites-flowers-and-groundcovers
