When do walnuts ripen?
The ripening period of walnut fruit varies with variety and climatic conditions. The ripening period of early-maturing varieties and late-maturing varieties can differ by 10-25 days. Generally, the ripening period in northern regions is mostly from early to mid September, while southern regions are relatively earlier. Walnuts ripen around the "White Dew" solar term, and it is advisable to delay harvesting by a few days; harvesting in stages and batches is best. Usually, the ripening period of scattered walnut trees is not very consistent, while that of walnuts grown in large plots is more consistent. In river valleys, river flats, hills and low-to-mid mountain areas, harvesting in early September is best, while in high mountain areas early to mid September is preferable.
