Vegetative Growth
Spring through early autumn (first year and into second)Plant develops dense foliage and branching structure; no flowers yet
Continue regular watering. Light pruning after flowering promotes bushier growth. Apply balanced, slow-release fertilizer in spring.
Bud Formation

Maintain consistent moisture. Do not over-fertilize with nitrogen as it reduces flowering. Avoid pruning that removes developing buds.
Flowering
November-April (5-6 months)Delicate bell-shaped flowers in white, pink, or purple shades cover the plant from November through April
