What Are the Sunlight Requirements for Clethra?
Clethra thrives in medium to bright indirect light but can tolerate light shade. Avoid direct, harsh sunlight to prevent leaf burn. For optimal growth, provide consistent light for at least 4-6 hours daily. Specific to clethra, dappled sunlight, as through a canopy, is ideal, mimicking its native understory habitat. Gardeners should consider the plant's natural preference for filtered light when positioning in the landscape or indoors.
