Growing, Harvesting and Storage

Carya illinoinensis grows best in well-drained, loamy soil with a pH between 6.0 and 7.5, in full sun to partial shade, and requires regular watering during its growing season to maintain soil moisture.

It thrives in temperate climates and benefits from mulching to retain soil moisture and suppress weeds. Regular pruning helps maintain its shape, promote air circulation, and reduce disease risk, while monitoring for pests like aphids and scale is essential for healthy growth. Harvesting occurs when the nuts are fully mature, typically in late summer to early fall, by gently shaking the branches to release the nuts, which are then collected and cleaned.

To preserve potency, the nuts should be dried thoroughly, stored in airtight containers in a cool, dark place, or refrigerated to extend shelf life and maintain their medicinal properties.
