Growing, Harvesting and Storage

Juniperus communis grows in a variety of environments, including rocky soils, sandy areas, and even coastal regions, thriving in well-drained soil and full sun.

It prefers a slightly acidic to neutral pH and is drought-tolerant once established, though regular watering during the first few growing seasons helps establish strong roots. For optimal growth, it requires minimal pruning, with occasional trimming to remove dead or diseased branches and promote air circulation. The best time to harvest juniper berries is in late summer to early autumn when the berries are fully mature and dark blue, using clean hands or a small mesh bag to collect them without damaging the plant.

To preserve potency, the berries should be dried in a cool, shaded area with good airflow, then stored in airtight containers in a cool, dark place or refrigerated to maintain their medicinal properties.
