Troubleshooting
Sweet Woodruff problems — and how to fix them
Sweet Woodruff (Galium odoratum) 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.
Invasive spreading
Spreads aggressively by rhizomes and self-seeding and can swamp smaller plants. Contain growth by installing root barriers or lifting and dividing colonies every 2–3 years.
Summer dormancy
Foliage yellows and dies back in hot, dry summers. Ensure consistent moisture and mulch to delay dormancy; it will re-sprout in cooler, moister conditions.
