What Are the Sunlight Requirements for Christmas cactuses?
Ideal Lighting: Partial sun
Christmas cactuses, indigenous to the dim understory of Brazil's rainforests, thrives in bright but indirect light. Optimal lighting mirrors this dappled sunlight, requiring exposure to moderate intensity for 10-14 hours daily. Direct sunlight can scorch leaves, while insufficient light impairs photosynthesis, inhibiting growth and flowering. To stimulate bud formation, christmas cactuses demands shorter daylight periods and cooler temperatures. Indoors, an east or west-facing window with sheer curtains is ideal. Outdoors, place christmas cactuses under partial shade, avoiding intense midday sun. Consistent lighting conditions support robust growth and vibrant blooms in christmas cactuses.
