watering
For the Woolly White Alder, it’s best to water thoroughly once a week in the summer and every 10 days during the cooler months. Be sure to water deeply until the soil is moist and water reaches the root zone, then allow the soil to dry out in between waterings. The Woolly White Alder will prefer slightly moist soils at all times, but avoid overwatering as this could cause root rot or fungus.
sunlight
Woolly white alder (Clethra tomentosa 'Cottondale') grows best in sites with full sun to part shade. In full sun, the plant will produce more flowers for longer periods. When planted in shady spots, the flowers will have a reduced bloom time but will still look attractive. When grown in full sun, the plant should be given 4-6 hours of direct sunlight per day. When grown in part sun, 2-4 hours of direct sunlight in the morning or late afternoon is ideal for this plant species.

If needed, lightly prune any new growth after flowering in late summer.
