How to grow petiolaris complex Drosera (sundews)

Petiolaris complex sundews are carnivorous plants from Australia, suited for more experienced growers. These sundews require high temperatures and plenty of sunlight. During dormancy, which typically occurs in the Northern Hemisphere’s winter, the plant dries out to protect itself during the dry season in its native habitat. Growth resumes after warming and the start of the rainy season. Below is a concise guide How to grow petiolaris complex Drosera (sundews), organized by their specific needs:

Light conditions: Maximum possible lighting year-round. Artificial lighting is necessary during winter.

Temperature: Higher temperatures, ideally above 25°C. Growth slows down at lower temperatures.

Substrate: Use clean fibrous peat mixed with silica sand or perlite in a 1:1 ratio.

Humidity: These plants thrive in higher humidity. Ideally, place them in a terrarium or a glass container.

Watering: The substrate must remain moist during the growth period. During dormancy, allow the substrate to dry out completely. Dormancy typically occurs in winter but may also happen outside this period.

Fertilizing: During the growing season, the plants can be „fed“ with insects if they cannot catch their own. If prey is accessible, they will capture it independently. Other forms of fertilizing are unsuitable.
