Q.Joe Pye Weed
I planted several of these plants in sun (0800-1500) to shade (after 1500. I have been watering twice a day (gets really hot and dry in SLC UT), however the plants are mostly wilted, a few have a couple of healthy looking leaves. I am wondering if there is anything I can do to save them?
Joe Pye Weed is rated for full sun to part shade but while it is getting established, try to give it some afternoon shade. Right now, the roots can't provide moisture fast enough to sustain the leaves. Shade cloth or ordinary cloth taped to two sticks will do it or garden statuary/birdbath might accomplish the task. This is temporary and will do more to help the plant than watering twice daily. There are a few species native to hot, dry areas but most commercial joe pye weed is native to the eastern half of US where summers are humid. Water deeply instead of frequently to entice the roots to go downward. Check the soil with a trowel to make sure the soil is damp at least 6 inches deep. Mulch should be 3 inches deep to help hold in moisture and keep the soil - and roots - from excessive heat.
