For safe use, it is recommended to follow recommended dosages, consult a qualified healthcare professional, and discontinue use if any adverse reactions occur.

Growing, Harvesting and Storage

Genista tinctoria grows best in well-drained, loamy soils that are slightly acidic to neutral, in full sun to partial shade, and requires regular watering during its growing season, though it is somewhat drought-tolerant once established.

It thrives in temperate climates and benefits from annual fertilization with a balanced, slow-release fertilizer to promote healthy growth and flowering. Regular pruning is essential to maintain its shape and encourage new growth, while monitoring for pests such as aphids and powdery mildew can help prevent disease. The best time to harvest the leaves and flowers is in early summer when the plant is in full bloom, using clean, sharp scissors to cut the stems without damaging the plant.

To preserve its potency, the harvested material should be dried in a shaded, well-ventilated area, then stored in airtight containers in a cool, dark place or refrigerated to maintain its medicinal properties.
