My amsonia looks like it's struggling. It has lost it's leaves on lower branches. It has been in the same spot- part sun, well drained soil. I don't see any insects on it. Any ideas?
Amsonia hub. needs full sun and space. Mine were in too much shade, crowded and were thinning. A move to full sun solved the problem.
Thanks. Maybe I'll move it in the fall. It is leaning towards light although I thought it got enough!!
