The clethra genus, popular for its summer blooming and pleasant fragrance, has a moderate care profile. Basic care involves full sun to partial shade exposure, regular watering, and well-drained, slightly acidic soil. It tolerates a wide temperature range, but prefers cooler climates. Common challenges include pests like aphids and leaf spot diseases. Seasonally, clethra requires winter mulching in harsh climates to guard against root damage, while spring pruning helps maintain its shape and promotes healthy growth.
