Everything it needs
9 essentials at a glance
Watering
Hydnora prefers to be watered sparingly.
Water every 2-3 weeks during the growing season (spring and summer), allowing the soil to dry out completely between waterings. In the dormant season (fall and winter), reduce watering to once a month. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and shriveling.
Light
Hydnora thrives in partial shade to full shade, ideally receiving 4-6 hours of indirect sunlight daily.
Direct sunlight can scorch the plant, so it is best placed in a location that mimics its natural habitat, such as under the canopy of larger plants.
Soil
The ideal soil for Hydnora is well-draining, sandy soil with a pH range of 6.0 to 7.0.
A recommended potting mix includes a blend of cactus mix and perlite to enhance drainage, ensuring that excess water can escape easily.
Humidity
Hydnora prefers moderate humidity levels around 40-60%.
To increase humidity, consider placing a humidity tray filled with water and pebbles beneath the pot or using a humidifier. Signs of humidity stress include browning leaf tips and leaf drop.
Temperature
Hydnora thrives in temperatures between 65-80°F (18-27°C) and is best suited for USDA hardiness zones 9-11.
It can tolerate brief periods of cooler temperatures but should be protected from frost, as it is sensitive to cold.
Fertilizing
Use a balanced, water-soluble fertilizer with an NPK ratio of 10-10-10 during the growing season, applying every 4-6 weeks.
In fall and winter, refrain from fertilizing. Signs of nutrient deficiency include stunted growth and pale leaves.
Pruning
Pruning is generally not required for Hydnora, but you can remove any dead or damaged leaves to promote healthy growth.
Use clean, sharp scissors for any cuts. If the plant becomes too large, you can trim it back in early spring to maintain its shape.
Repotting
Repot Hydnora every 2-3 years or when you notice roots growing out of the drainage holes.
Choose a pot that is 1-2 inches larger in diameter. Signs it needs repotting include stunted growth and water pooling on the surface. Carefully remove the plant, refresh the soil, and replant.
Propagation
Hydnora is typically propagated through division or offsets.
The best time to propagate is in spring. Carefully remove the plant from its pot, separate the offsets with clean, sharp tools, and replant them in suitable soil. Ensure the new plants are watered lightly until established.
When it's unhappy
Yellowing leaves
Why it happens
Typically caused by over-watering or nutrient deficiency.
How to fix it
Ensure proper watering practices and consider fertilizing if nutrient levels are low.
Root rot
Why it happens
Excess moisture in the soil leading to fungal growth.
How to fix it
Allow the soil to dry out completely and improve drainage. If severe, repot the plant in fresh, dry soil.
Browning leaf tips
Why it happens
Low humidity levels or underwatering.
How to fix it
Increase humidity around the plant and adjust watering frequency.
Wilting
Why it happens
Under-watering or extreme temperature changes.
How to fix it
Check soil moisture and water if dry. Protect from temperature extremes.
Stunted growth
Why it happens
Nutrient deficiency or root-bound conditions.
How to fix it
Fertilize appropriately and consider repotting if the plant is root-bound.
Care through the year
Spring
In spring, increase watering frequency as the plant begins to grow. Fertilize every 4-6 weeks with a balanced fertilizer to support new growth.
Summer
During summer, maintain consistent moisture but avoid over-watering. Ensure the plant is in partial shade to prevent leaf scorch.
Fall
In fall, gradually reduce watering as the plant enters dormancy. Stop fertilizing and monitor for any signs of stress.
Winter
In winter, water sparingly, about once a month. Keep the plant in a cool location away from frost, and avoid fertilizing.
Toxicity & Safety
Hydnora is considered toxic if ingested, particularly the roots and flowers. Symptoms of ingestion may include nausea, vomiting, and abdominal pain. Keep away from pets and children.
