Watering. Water regularly during the growing season to keep the soil moist but not soggy. Reduce watering in winter. Mulching helps retain soil moisture.
Fertilizing. Feed with a balanced, slow-release fertilizer in early spring and again in mid-summer to support healthy growth and flowering. Avoid over-fertilizing, which can cause excessive leaf growth at the expense of flowers.
Viburnum odoratissimum is a hardy shrub that grows quickly and adapts well to different light conditions, from full sun to partial shade. It prefers well-draining soil and regular watering but can tolerate short dry periods. Minimal maintenance is needed, though occasional pruning helps keep its shape and encourages healthy growth.
