Sowing calendar: December 2025

When to sow and plant in December? Folk tradition uses the Moon’s phase and zodiac sign: above-ground crops are sown during the waxing Moon and root crops during the waning Moon. The sign defines the day type: root, leaf, fruit or flower. These traditions are not scientifically proven.
