Haworthia ‘Savanna’ is a distinctive and popular succulent, admired for its unique appearance and adaptability as a houseplant. Its compact size and interesting foliage make it a favored choice for indoor gardeners.
Understanding Haworthia ‘Savanna’
Haworthia ‘Savanna’ is a cultivar within the Haworthia genus, comprising small, slow-growing succulents native to Southern Africa. These plants form rosettes of fleshy leaves, resembling miniature aloes. The ‘Savanna’ cultivar features upright, lance-shaped leaves, often ghost green or silvery-grey, adorned with textured bumps and sharp tips. Some varieties may display white warts or bands on their foliage.
Essential Care for Haworthia ‘Savanna’
Light Requirements
Haworthia ‘Savanna’ thrives in bright, indirect light, mimicking its natural habitat. While it can tolerate some direct morning sun, prolonged exposure to intense afternoon sunlight can scorch its leaves, leading to discoloration or bleaching. Place it near a bright window that receives filtered light, or a few feet away from a sunny window. Insufficient light can cause the plant to turn white or lose its vibrant coloration.
Watering Practices
Proper watering is important for Haworthia ‘Savanna’. This succulent stores water in its fleshy leaves, allowing it to tolerate periods of drought. Thoroughly soak the soil, then allow it to dry completely before rewatering. This helps prevent root rot, a common issue for succulents. During cooler months, such as winter, reduce watering frequency significantly, perhaps to once a month.
Soil and Drainage
The right soil mix for Haworthia ‘Savanna’ focuses on excellent drainage. A well-draining succulent or cactus potting mix is ideal, often including perlite, pumice, or coarse sand to enhance aeration and prevent water pooling. Plant in a pot with drainage holes to allow excess water to escape. Terracotta pots can further prevent overwatering by allowing moisture to evaporate through their walls.
Temperature and Humidity
Haworthia ‘Savanna’ prefers average room temperatures, between 65-82°F (18-28°C). Protect the plant from frost and extreme cold, as temperatures below 39°F (4°C) can cause damage. Average household humidity is sufficient; special misting is not required. Avoid high humidity environments like terrariums, which increase the risk of root rot.
Fertilizing Needs
Haworthia ‘Savanna’ has minimal fertilizing requirements. A diluted, balanced succulent or cactus fertilizer can be applied sparingly during the active growing season (spring and summer), once a month or every few months. Avoid fertilizing during winter dormancy. Over-fertilization can harm the plant, so use a weaker solution than recommended.
Addressing Common Haworthia ‘Savanna’ Issues
Overwatering Signs and Solutions
Overwatering is a frequent problem, quickly leading to root rot. Signs include mushy, soft, or yellowing leaves, and a soft plant base. If these symptoms appear, stop watering immediately and allow the soil to dry completely. In severe cases, repot into fresh, dry, well-draining soil after trimming rotted roots. Ensure the pot has drainage holes to prevent water accumulation.
Underwatering Symptoms
While overwatering is more common, underwatering can also occur. Leaves may appear shriveled, wrinkled, or thin, and the potting mix will be bone dry. To address, provide a thorough watering, allowing drainage. Leaves should plump up within days as the plant rehydrates.
Sunburn and Light Stress
Too much direct sunlight can cause stress and sunburn. Symptoms include discolored patches (white, yellow, or reddish) that may become bleached or crispy. If sunburn occurs, move the plant to bright, indirect light or provide shading during peak sun. Gradually acclimating the plant can prevent future sunburn.
Pests to Watch For
Haworthias are generally pest-resistant, but some can still pose a threat. Mealybugs are common succulent pests, appearing as small, white, cottony masses in leaf crevices or on roots, weakening the plant by feeding on sap. Other potential pests include spider mites and scale insects. Addressing pest issues involves isolating the plant, physically removing pests with rubbing alcohol on a cotton swab, or using insecticidal sprays. Good air circulation and avoiding excessive moisture can deter pests like fungus gnats.
Propagation and Growth of Haworthia ‘Savanna’
Haworthia ‘Savanna’ is a slow-growing succulent that forms clumps or rosettes. It naturally produces offsets, often referred to as “pups,” around the base of the mother plant. These offsets are the easiest propagation method.
To propagate, carefully separate a pup from the parent plant, ensuring it has developed some roots. Allow the separated offset to callus for a day or two before planting in well-draining succulent mix.
Repotting is infrequent for Haworthia ‘Savanna’ due to its slow growth. Repotting is needed every few years, or when the plant is root-bound. When repotting, choose a container one or two sizes larger with drainage holes. Haworthias are non-toxic to pets, including dogs and cats.
