Plant delavaya in a spot which receives sufficient light and is sheltered from harsh weather. When positioning, space adequately to allow for mature size. After planting, water deeply, maintaining a regular watering schedule. Each species in delavaya may have unique needs, so it's crucial to understand these differences. Consistent care and monitoring are key for healthy growth.
