Growing, Harvesting and Storage

Hypericum perforatum grows best in well-drained, loamy soil with a slightly acidic to neutral pH, in full sun to partial shade, and requires moderate watering to keep the soil consistently moist but not waterlogged.

It thrives in temperate climates and is relatively low maintenance, needing regular weeding and occasional pruning to promote bushier growth and prevent legginess. Harvesting should occur during the summer months when the flowers are fully open, typically between June and August, using sharp scissors or shears to cut the stems just above a leaf node to encourage regrowth. To preserve potency, the harvested material should be dried in a cool, dark, and well-ventilated area, then stored in airtight containers away from light and moisture.

Proper storage ensures the retention of active compounds like hypericin and flavonoids, maintaining the plant's medicinal efficacy for extended periods.
