watering
Sweet pepperbush (Clethra alnifolia 'September Beauty') performs best in moist soil. When you first plant it, it's important to water it thoroughly to ensure proper establishment of roots. After that, water 1-2 times a week during its first growing season, but avoid overwatering. Once established in the ground, it only needs watering during periods of extended dryness, usually every 10-14 days.
sunlight
Sweet pepperbush (Clethra alnifolia 'September Beauty') thrives in full sun, meaning at least 6 hours of direct sunlight per day. This plant does best in temperatures between 50 and 85 degrees Fahrenheit. On extremely hot days, partial shade may be beneficial. Provide adequate water for optimal growth and flowering. Keep the soil moist but not soggy, and allow it to dry slightly between waterings.
pruning
For sweet pepperbush (Clethra alnifolia 'September Beauty'), pruning should be done in the spring as new growth begins. Dead branches should be removed at that time, as well as any crossing branches. Pruning should also be used to establish the desired shape for the plant. Generally, no more than 1-third of the total branches should be trimmed off. Some summer maintenance may be needed if necessary, but it should be kept minimal. It is best to leave any new growth unpruned until the following spring.
