sweet pepperbush

Water Sweet Pepperbush plants thoroughly when planting and regularly while they are establishing (the first 6-8 weeks). In general, you should water the plants deeply once per week, soaking the soil so that it is moist but not soggy. During particularly hot or dry periods, increase watering to 2-3 times per week (but avoid overwatering). Once the plants are established, reduce watering frequency to 1-2 times per month in the summer (but not during periods of drought). During the winter months, water the plants only when the soil is dry, or not at all (as the plant will go dormant).

Sweet pepperbush (Clethra alnifolia 'Sotite' WHITE DOVE') prefers full sun but will tolerate partial shade. It will thrive with at least 4 to 6 hours of direct sunlight each day, though it can tolerate more than 6 hours per day and will continue to produce vibrant blooms. Too much direct sunlight will cause scorching and can affect its health. If the plant is receiving too much direct sunlight, it may need to be moved to a spot with less intense afternoon sun.

Prune sweet pepperbush in early spring before new growth begins so as not to sacrifice any growth. Pruning should be used to selectively remove dead, damaged, or diseased wood, while also controlling plant size and promoting bushier growth. For a more compact and fuller-looking plant, pruning back about 1-half of the growth in early spring will typically produce the desired shape and size. Utilizing thinning cuts made from the interior of the plant helps to open up the canopy by removing larger branches and allowing more light into the center of the shrub. Prune lightly to encourage side branching. Removing the old flowering stems after flowering will promote new growth and repeat blooms.
