Hens and chicks (Sempervivum) are popular, hardy succulents known for their rosette-shaped foliage and low maintenance. Light is essential for their health, vibrant appearance, and compact growth.
Understanding Hens and Chicks Light Needs
Hens and chicks flourish outdoors in full sun, ideally receiving at least 6 to 8 hours of direct sunlight daily. Once acclimated, they can tolerate intense sunlight, which helps them develop vibrant coloration. Insufficient outdoor light will cause the plants to stretch and lose their compact form.
When grown indoors, these succulents require the brightest possible location. A south-facing window is ideal, providing ample natural light throughout the day, even during winter months. If natural light is insufficient, supplemental full-spectrum LED grow lights are recommended. Position these lights approximately 6 to 12 inches from the plants for optimal intensity. Hens and chicks prefer high intensity for extended periods, typically 12 to 16 hours daily.
Signs of Incorrect Light Exposure
Hens and chicks show their light needs through their appearance. Too little light causes etiolation, characterized by stretching, elongated stems, and increased space between leaves. The foliage may also appear duller in color and lack its usual compactness as the plant attempts to “reach” for more light. This stretching can weaken the plant over time.
Conversely, too much intense light can cause issues, though some color changes are a healthy stress response. Symptoms of excessive light, such as sunburn, include bleached or faded leaf colors, or browning and blackening of leaf tips or edges. A scorched appearance indicates damage, which can be permanent. While certain varieties may develop red tips or deeper hues in bright conditions, extreme discoloration suggests the plant is receiving more light than it can tolerate.
Adjusting Light for Healthy Growth
Correcting light issues is important for maintaining healthy hens and chicks. To increase light for etiolated plants, outdoor specimens should be gradually moved to brighter spots to prevent shock. For indoor plants, relocating them to a sunnier window can provide more natural light. If natural light remains insufficient, introducing a full-spectrum LED grow light is beneficial. When using grow lights, begin with a shorter duration, perhaps 6 hours, and gradually increase it over several weeks to 12 to 16 hours daily, allowing the plant to acclimate.
To decrease light for plants showing signs of sunburn, outdoor hens and chicks benefit from partial afternoon shade, especially during intense heat. Temporary shade cloths can also diffuse harsh midday sun. For indoor plants, moving them slightly away from a very bright window or using sheer curtains can help diffuse intense light. Gradual acclimation is important when transitioning plants between different light conditions to prevent shock.
