How to grow Darlingtonia californica
A less common species of carnivorous plant that captures its prey in gravity traps resembling an upright cobra. A brief guide on how to grow Darlingtonia californica is divided according to the individual conditions the plant requires.
Light conditions: Maximum possible light. Due to the plant’s sensitivity to root overheating, it is best to provide plenty of morning and evening sun (east and west exposure), while shading it from direct southern sunlight.
Temperature: Normal room temperature is suitable, and the plants benefit from being kept outdoors during summer. The plants are sensitive to root overheating, so they should be protected from extreme summer temperatures. In winter, lower the temperature to 5–10 °C.
Substrate: A light substrate helps protect the roots from overheating. Pure fibrous peat mixed with perlite and silica sand in a ratio of 2 : 2 : 1.
Air humidity: They prefer higher air humidity, but it is not necessary to keep the plants in closed terrariums. The plants should not be misted.
Watering: The plants should always stand in water and are watered using the tray method. The ideal water level is approximately 1–2 cm. In winter, reduce watering and keep the water level at about 0–1 cm. The substrate must never dry out, even during winter.
Fertilization: During the growing season, the plants can be “fed” with insects if they cannot catch them on their own. If they have the opportunity, they will capture insects themselves. Other forms of fertilization are not suitable.
