Care Guide

💧

Watering

Water sweet pepperbush bushes regularly throughout the growing season. Water deeply, supplying the roots with at least 1 inch of water per week. Be sure to water during dry spells and especially when the plant is flowering and setting buds. Avoid over-watering, as this can cause root rot and other diseases. Water at the base of the plant, avoiding wetting the foliage. Water in the morning, early enough for the foliage to dry by nightfall to reduce disease risks.

☀️

Light

Sweet pepperbush is a native, deciduous shrub of North America that grows well in sunny, well-drained locations. It should be planted in an area that provides at least 6 to 8 hours of direct sunlight during the growing season, and preferably more, if possible. During the winter months, however, sweet pepperbush can tolerate partial shade. Too much shade can lead to the plants suffering from a lack of growth and lack of flowering.
