How to grow tuberous Drosera (sundews)
Tuberous sundews are carnivorous plants from Australia, recommended for experienced growers. These plants have their growth period during winter in the Northern Hemisphere, while they enter dormancy in summer by retreating into a tuber below the substrate surface. Below is a concise guide How to grow tuberous Drosera (sundews), organized by the conditions they require:
Light conditions: During the growth phase, provide maximum possible light. Since growth typically occurs in winter, artificial lighting is necessary.
Temperature: Maintain standard room temperature throughout the year.
Substrate: Use clean fibrous peat mixed with silica sand or perlite in a 1:2 ratio.
Humidity: They are quite adaptable, thriving in both fresh air and higher humidity levels in terrariums.
Watering: During the growth phase, the plants should always stand in water. During dormancy, allow the substrate to dry out. The ideal water level during growth is approximately 1 cm.
Fertilizing: During the growth season, the plants can be „fed“ with insects if they cannot catch their own prey. If prey is accessible, the plants will capture it themselves. Other forms of fertilizing are unsuitable.
Photographs of tuberous sundews can be found in the „My Collection“ section.
