How to sow Drosera seeds
Subtropical, non-dormant Drosera
Sundew seeds from subtropical species are very tiny but germinate well and readily. Due to their small size, care should be taken to ensure the seeds are not sown too closely together. Seedlings need adequate space to grow. A folded piece of paper shaped into a small funnel can assist with precise sowing. Below is a concise guide on how to sow Drosera seeds and providing the ideal conditions for seedlings:
Light conditions: Diffused light. Avoid exposing seeds to direct sunlight, as it may cause overheating.
Temperature: Regular room temperature.
Substrate: A mixture of peat and silica sand or perlite in a 2:1 ratio. Seeds should be sown on the surface without covering them.
Air humidity: Germination occurs best at 100% humidity. Cover the pot with transparent foil to preserve moisture while allowing light through. Gradually acclimate the seedlings to the humidity levels needed for mature plants.
Watering: The substrate must remain consistently moist.
Germination time: Typically 3–6 weeks.
Winter-growing Drosera
Sundew seeds of tuberous species with overwintering buds are tiny but germinate well and willingly. Care should be taken to ensure that seeds are not sown too close together. Seedlings require space to grow. A folded piece of paper shaped into a small funnel can help with precise sowing. Below is a concise guide on how to sow sundew seeds and the conditions needed for their seedlings:
Light conditions: Diffused light. Be careful to avoid overheating seeds under direct sunlight.
Temperature: Normal room temperature. Seeds need cold stratification before sowing. Given their size, it is easiest to sow them directly onto the substrate and place the pot inside a sealable bag in the refrigerator. Leave them in the fridge for 4–5 weeks before continuing with sowing.
Substrate: A mix of peat with silica sand or perlite in a 2:1 ratio. Seeds should be sown on the surface without being covered.
Air humidity: Ideal germination occurs at 100% humidity. Cover the pot with transparent foil to retain moisture while allowing light to penetrate. Gradually acclimate young seedlings to the humidity levels suited for mature plants.
Watering: Keep the substrate consistently moist.
Germination time: Typically 3–6 weeks.
