Water: Undulate alkanet prefers moderate rainfall and requires weekly watering for optimal growth. It thrives in well-drained soil to avoid overwatering and root rot, making it suitable for outdoor cultivation.
Fertilize: Undulate alkanet benefits from a balanced fertilizer applied every 4-6 weeks during the growing season to promote growth. Switch to a high-nitrogen fertilizer when blooming starts, and reduce frequency in autumn to prevent root burn. Ensure even distribution and thorough watering for optimal nutrient uptake.
Pruning: Undulate alkanet features wavy leaves and blue flowers. Prune in early to late spring by removing dead stems to promote healthy, bushy growth and flowering. Use sharp, sanitized tools to prevent disease and ensure a vigorous plant.
Propagation: Originating from the Boraginaceae family, undulate alkanet is a perennial herb that thrives in well-drained soils and sunny conditions. Propagation involves collecting and sowing delicate seeds directly into a prepared seedbed, ensuring consistent moisture and protection for healthy seedlings ready for transplanting.
