Common Broomrape problems — and how to fix them
Common Broomrape (Orobanche minor) 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.
Host plant unavailability
Cannot establish or survive without a suitable host; if trying to encourage it in a wildflower setting, ensure a dense stand of compatible clovers or bird's-foot trefoil is already established in low-fertility, calcareous soil.
Seed germination failure
Seeds are dust-like and germination requires proximity to a live host root to produce the chemical stimulus (strigolactones) needed; sowing without a host present results in complete failure.

Most common broomrape issues are care-mismatch, not bad luck. Dial in the basics:
