How to grow Byblis (Rainbow plants)
Byblis (Rainbow plants) are uncommon carnivorous plants found in collections, consisting of seven unique species. Notably, two of these species are perennials, whereas the others are annuals. Additionally, their leaves attract prey through shiny droplets that resemble dew, effectively trapping insects upon contact. Below is a guide on how to grow Byblis (Rainbow plants), carefully divided based on the conditions these intriguing plants require.
Light conditions: To begin with, providing the maximum possible sunshine and light is crucial for optimal growth. Specifically, a south-facing window is the most suitable choice. If south-facing windows are not an option, then east- or west-facing windows can also suffice.
Temperature: Next, it is important to maintain a regular room temperature throughout the year. During summer, the plants tolerate outdoor conditions exceptionally well. On the other hand, annual plants die off during winter, while perennial plants can overwinter at temperatures around 10–15°C. However, if adequate light is provided, overwintering becomes unnecessary.
Substrate: Moving on, the ideal substrate consists of pure fibrous peat mixed with silica sand or perlite in a 1:1 ratio. This mixture ensures a suitable environment for the plants.
Air humidity: As for humidity, it is worth mentioning that these plants are not particularly demanding in this regard. Furthermore, there is no need to mist them, as they thrive without additional humidity.
Watering: In terms of watering, it is recommended to water from below by placing the pot in a shallow tray. Ideally, the water level should remain at about 1 cm. Additionally, during winter, it is advisable to reduce watering, although care must be taken to ensure the substrate does not dry out completely.
Fertilizing: Lastly, when it comes to fertilizing, the plants can be fed insects during the growing season, especially if they are unable to catch their own prey. Alternatively, if insects are accessible, the plants will capture them independently. However, other forms of fertilization are unsuitable and should be avoided.
