A Sundew Spectacle: Cultivating a Drosera Burmannii Mound
For those with a passion for the peculiar and a penchant for the predatory, the world of carnivorous plants offers a captivating realm. Among these fascinating flora, sundews (Drosera) stand out with their glistening, dew-covered tentacles, patiently awaiting their next meal. Today, we delve into the rewarding experience of cultivating a sundew mound, specifically focusing on the charming Drosera burmannii.
The Allure of Sundews
Sundews, belonging to the genus Drosera, are a diverse group of carnivorous plants found across the globe. They get their name from the glistening, sticky mucilage that covers their leaves, resembling dewdrops. These “dewdrops” are actually a potent trapping mechanism. Insects, lured by the bright appearance and sweet scent of the mucilage, become ensnared upon contact. The tentacles then curl inward, further securing the prey and initiating the digestive process. This adaptation allows sundews to thrive in nutrient-poor environments where they supplement their diet with captured insects.
Drosera burmannii, often referred to as the tropical sundew or the short-leaved sundew, is a particularly appealing species for both novice and experienced carnivorous plant enthusiasts. Native to Southeast Asia and Australia, this sundew is relatively small, typically forming a rosette of leaves close to the ground. Its compact size and ease of care make it an excellent choice for terrariums, greenhouses, or even sunny windowsills.
Crafting Your Own Sundew Mound
Creating a sundew mound, as opposed to growing them in individual pots, is a great way to create a visually striking display and also creates a microclimate that the sundews will thrive in. The following steps outline the process of creating a thriving Drosera burmannii mound:
-
Planning and Preparation:
- Choose Your Location: Drosera burmannii thrives in bright, sunny conditions. Select a location that receives at least 6 hours of direct sunlight per day. A south-facing windowsill, a well-lit greenhouse, or a spot under grow lights are all suitable options.
- Select a Container: The size and shape of your container will depend on the space available and the desired aesthetic. Terracotta pots, plastic containers, or even repurposed containers can all be used. Ensure the container has drainage holes to prevent waterlogging.
- Gather Supplies: You’ll need the following:
- Drosera burmannii seedlings (these can be started from seeds, propagated from leaf cuttings, or purchased from a reputable carnivorous plant supplier).
- Sphagnum moss (long-fibered sphagnum moss is preferred).
- Perlite or horticultural sand.
- A container with drainage holes.
- Pure water (distilled, reverse osmosis, or rainwater – tap water contains minerals harmful to sundews).
- Prepare the Growing Medium: Drosera burmannii requires a nutrient-poor, acidic soil. A mixture of long-fibered sphagnum moss and perlite or horticultural sand works exceptionally well. The sphagnum moss provides moisture retention and aeration, while the perlite or sand improves drainage. A common ratio is 1:1, but you can adjust it based on your preferences and environmental conditions. Thoroughly rinse the perlite or sand to remove any dust before mixing.
-
Constructing the Mound:
- Moisten the Sphagnum Moss: Soak the long-fibered sphagnum moss in pure water until it is thoroughly saturated. Gently squeeze out the excess water, leaving the moss damp but not dripping.
- Mix the Growing Medium: Combine the moistened sphagnum moss with the perlite or sand in your container. Mix thoroughly to ensure an even distribution of the components.
- Create the Mound: The most important step here is to create a mound shape. This will help with drainage and allow you to grow more sundews. The height of the mound will depend on your container, aim for at least 4 inches in height in the center. You can also use this as a visual indicator of the quality of the mound. A good mound will hold its shape even if not fully saturated with water.
-
Planting the Seedlings:
- Prepare the Seedlings: Gently remove the Drosera burmannii seedlings from their original containers. Handle the delicate roots with care.
- Planting: Using a small tool, such as tweezers, make small holes in the growing medium of your mound. Space the seedlings about 1 inch apart. Gently place each seedling into a hole and lightly press the growing medium around the roots. This will help the sundews get established more quickly.
- Watering: After planting, gently water the mound with pure water. Water from the top, allowing the water to soak through the growing medium. Ensure that the mound is evenly moist but not waterlogged. The top of the mound should remain damp, but not soggy.
Caring for Your Sundew Mound
Once your Drosera burmannii mound is established, proper care is essential for its long-term health and vitality.
- Watering: Water your sundew mound regularly, typically every 1-3 days, depending on the environmental conditions. Keep the growing medium consistently moist, but avoid allowing the container to sit in standing water. The ideal watering method is to water from the top, ensuring the entire mound receives moisture.
- Light: Drosera burmannii requires bright, direct sunlight. Place the mound in a location that receives at least 6 hours of direct sunlight per day. If natural light is insufficient, supplement with grow lights. LED grow lights are an energy-efficient and effective option.
- Humidity: Sundews thrive in humid environments. If your home or growing environment is dry, you can increase humidity by placing the container on a tray of pebbles with water, or by using a humidifier. Ensure good air circulation to prevent fungal diseases.
- Feeding: While Drosera burmannii can catch insects on their own, you can supplement their diet by feeding them small insects. Small fruit flies, gnats, or even finely ground fish food can be offered. Avoid overfeeding, as this can lead to stress and potential problems.
- Temperature: Drosera burmannii prefers temperatures between 65-80°F (18-27°C). Avoid exposing the plants to extreme temperatures or sudden fluctuations.
- Dormancy: Drosera burmannii does not require a specific dormancy period like some other sundew species. However, they may slow their growth during the cooler months. Continue to provide bright light and regular watering during this period.
- Repotting: As your Drosera burmannii mound grows, you may need to repot it into a larger container. Repotting is typically done every 1-2 years. Gently remove the plants from the old container and transplant them into a fresh growing medium in a clean container. Be careful to not damage the roots.
Troubleshooting Common Problems
Despite their captivating nature, Drosera burmannii can sometimes face challenges. Here are some common problems and their solutions:
- Lack of Dew: If your sundew is not producing dew, it may be due to insufficient light, low humidity, or improper watering. Ensure that the plant is receiving adequate sunlight, maintaining appropriate humidity levels, and watering regularly with pure water.
- Yellowing Leaves: Yellowing leaves can indicate various problems, including overwatering, nutrient deficiencies, or pests. Check the growing medium to ensure it is not waterlogged. Use pure water, and avoid fertilizing the plant. Inspect the plant for any signs of pests, such as spider mites or aphids.
- Fungal Diseases: High humidity can sometimes lead to fungal diseases. Ensure good air circulation around the plant and avoid overcrowding. Remove any infected leaves promptly. Consider using a fungicide specifically formulated for carnivorous plants if necessary.
- Pests: Aphids, spider mites, and mealybugs can sometimes infest sundews. Inspect the plants regularly for pests. If pests are present, isolate the affected plant and treat it with a suitable insecticide or insecticidal soap, following the product’s instructions carefully.
