Lunar Planting Calendar for August 2026: When to Sow and Harvest
August is one of the most important months for vegetable gardeners and gardeners. During this period, they actively harvest crops, sow crops for fall consumption, prepare future strawberry plantings, transplant perennials, and get the garden ready for the approaching fall.
When planning their work, many Ukrainians rely not only on the weather forecast but also on the lunar calendar. It is believed that the phases of the moon influence the flow of sap in plants, the development of the root system, and the growth rate of the above-ground parts.
Moon Phases in August 2026
- August 1–11 – Waning Moon;
- August 12 – New Moon;
- August 13–27 – waxing moon;
- August 28 – Full Moon;
- August 29–31 – waning Moon.
Recommendations for most gardening and farming tasks traditionally depend on these phases.

In August 2026, the best days for sowing most crops are considered to be:
