Care Guide
Watering
Sweet pepperbush should be watered regularly. Aim to water it at least once a week, but provide a deep watering when the top inch of soil feels dry to prevent the plant from being stressed. Generally, the plant prefers evenly moist soil. During dry spells, check the plant regularly to ensure it is still getting enough water. If any wilting is observed, apply a thorough soaking and check the soil for moisture to determine if more frequent watering is necessary.
Light
Sweet pepperbush (Clethra alnifolia 'Crystalina') requires full sun exposure for optimal growth and flowering. It is ideally grown in areas that receive 6 to 8 hours of direct sunlight each day. It will tolerate some light shade but will require more maintenance if it is planted in shady areas. If it is planted in full sun, it may require more frequent watering to keep its foliage vibrant and lush.
Temperature
Hardiness zone 4–8.
Pruning
Sweet pepperbush (Clethra alnifolia 'Crystalina') can be pruned in the spring, just after it blooms. Pruning should be limited to removing any dead or damaged limbs. Light pruning can be used to keep the shrub more manageable and to maintain a certain shape. Prune each stem at the point where 2 branches meet, pointed up and away from the center of the shrub, to allow light in and encourage new growth. To keep the shrub compact, it can also be selectively pruned to reduce the amount of woody growth, or by removing entire stems or branches at ground level.
