How to Grow and Care

Sweet Joe Pye Weed is happiest with full sun to part shade in moist to wet soils. It prefers that the soil does not dry out, which is why clay works well for Joe Pye. It has no serious insect or disease problems.

Sweet Joe Pye Weed just isn't a fussy or difficult plant to grow. If you do not want Sweet Joe Pye Weed to spread hither and yon, then cut the seed heads off.

If you are propagating by seed in the fall, then plant thickly as germination is usually low. Propagation is best from softwood cuttings taken in late spring or by division in fall as they go dormant or in the spring just as shoots first appear. See more at Growing and Using Sweet Joe Pye Weed.
