Other Comments:
I love this plant and would love to keep it. I normally just ignore the plant, but it really looks bad. I’m thinking of cutting it back. It is planted in afternoon full sun, although a hydrangea is planted close by in the shade. I don’t think water is an issue, unless it’s being overwatered. Hydrangea is doing fine. Any suggestions would be helpful. Thanks

Hi Mary Jo, I really need a photo to be able to help you. If no photo, dig two small holes 6 inches deep with a trowel either side of the plant. If the soil is dry, try to get a soil wetting agent and use it as per directions, then water the plant for 20 minutes with a sprinkler. Pruning will do no good – it never does, it just makes the plant look a bit tidier. Good luck, Don.
