How to grow Roridula
Roridula is a rare carnivorous plant native to South Africa, suitable for experienced growers. It produces a strong adhesive secretion capable of trapping insects and even birds. Unlike most carnivorous plants, Roridula does not digest its prey directly. Instead, it lives in symbiosis with beetles that feed on the trapped prey and produce excrement, which the plant absorbs. Below is a concise guide How to grow Roridula, organized by the conditions it requires:
Light conditions: Provide maximum possible lighting. A south-facing window is ideal, although east- or west-facing windows also work well.
Temperature: Maintain normal room temperature. The plant benefits from nighttime temperature drops.
Substrate: Use clean fibrous peat mixed with silica sand or perlite in a 1:1 ratio.
Humidity: Fresh air is essential. Avoid placing the plant in glass containers or terrariums. The plant does not require misting. Ensure adequate air circulation to prevent mold.
Watering: Keep the substrate consistently moist, but avoid waterlogging.
Fertilizing: Unlike other carnivorous plants, Roridula cannot absorb trapped insects directly. Therefore, it requires more frequent repotting to maintain sufficient nutrients. Alternatively, careful fertilization using specialized carnivorous plant fertilizers or providing symbiotic beetles can help with nutrient supply.
