The Amish plant by lunar calendar.
Rules
Waxing moon: above-ground crops — tomatoes, peppers, greens. Waning: root crops — carrots, potatoes, onions. New/full moon — don’t plant, weed.
Science
No direct proof. But moon affects tides, groundwater, insects. Amish use it and are satisfied.
Practical Benefit
Lunar calendar provides discipline: new work cycle every 2 weeks.
