Care tips
It prefers a location with partial shade to full sun, though it tolerates shade better in hot, dry climates. It needs moist, well-drained, and slightly acidic soil, avoiding waterlogging. Water regularly, especially during dry periods, to keep the soil consistently moist. A common mistake is planting it in poor or very compacted soils, which can limit its growth and vitality.
