Cinnamon or chamomile tea prevents damping-off in seedlings.

Contested

Cinnamon and chamomile tea are popular anti-damping-off remedies because cinnamon is antifungal in a lab dish. But there's no good evidence either one saves a seed tray. What prevents damping-off is the setup: fresh sterile mix, clean pots with drainage, warmth and airflow, and going easy on the water.

What is actually known

Cinnamon contains compounds with antifungal activity in a lab dish, which is where this remedy comes from, but there is no reliable evidence that dusting cinnamon, or watering with chamomile tea, prevents damping-off on a seed tray. What prevents damping-off is the setup: fresh sterile mix, clean containers with drainage, warmth and airflow, and not overwatering. A remedy sprinkled on top does not fix a cold, wet, overwatered tray, which is where damping-off comes from.

How we grade evidence

Well established
The rule names its mechanism and is settled, by sources a person has read and checked or by plain arithmetic and geometry.
Promising
The mechanism is named and the literature backs it. A few questions are still open.
A good hunch
Plausible by its mechanism, but field studies are thin, so treat it as a lean.
Contested
The evidence points both ways, or no study has tested it, so the planner does not enforce it.
Contested here means nothing we found supports it.
Refuted
The claim did not survive its sources. It is kept so the folklore can be answered.
