Troubleshooting
Greater Plantain problems — and how to fix them
Greater Plantain (Plantago major) 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.
Excessive self-seeding
Each plant can produce thousands of seeds. In cultivated gardens, remove flower spikes before seeds mature to prevent naturalising across beds and lawns.
Taproot regrowth after weeding
When grown as a weed rather than a crop, the deep taproot regenerates readily if not fully removed. Dig out the entire root when controlling spread.
Leaf spot (Ramularia)
Pale tan spots with darker margins can appear in wet seasons. Usually cosmetic. Remove and dispose of affected leaves; improve drainage and air circulation.
