Troubleshooting
Woodruff problems — and how to fix them
Woodruff (Galium odoratum) 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.
Aggressive spreading
Vigorous rhizomes can overrun neighbouring plants in moist shade; use a barrier or site where it can roam freely.
Scorch in sun and drought
Foliage browns in direct sun or dry soil; move to shade and keep the ground consistently moist.
Summer dieback when dry
Hot, dry spells cause the carpet to go dormant and brown; deep mulch and watering keep it green for longer.
Thinning in deep dry shade
Dry shade under thirsty trees gives sparse cover; improve soil with leaf mould and water during establishment.
Prevent woodruff problems before they start
Most woodruff issues are care-mismatch, not bad luck. Dial in the basics:
