Troubleshooting
Aromatic Aster 'Raydon's Favorite' problems — and how to fix them
Aromatic Aster 'Raydon's Favorite' (Symphyotrichum oblongifolium) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Flopping in rich soil
Excess fertility causes lanky, sprawling stems; grow in lean, free-draining soil and avoid high-nitrogen feeds.
Crown rot in wet winters
Excellent drainage is essential; in heavy soils, plant on a slight mound or incorporate grit to prevent crown saturation.
Clump die-out
Lift and divide every 3-4 years in spring to maintain vigour and prevent central dieback.
Late frosts
Early emerging shoots can be damaged by late spring frosts; protect with fleece if a frost is forecast after buds appear.
