Troubleshooting
Early Goldenrod problems — and how to fix them
Early Goldenrod (Solidago juncea) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Aggressive spread
Rhizomatous spread can crowd neighbouring plants within 2–3 seasons; divide every two years in spring and use root barriers if confining to a border.
Leaf rust
Orange or yellow pustules on foliage from Coleosporium solidaginis can appear in mid-to-late summer, particularly in humid sites; remove affected leaves and improve air circulation around clumps.
