Earlier this week I mentioned that my Drosera intermedia 'Cuba' have formed hibernacula for winter, and are going dormant. They look pretty quiet right now.

When it came to repotting, however, results we a lot more mixed. When the seedlings were very small I transferred about half of them to a new pot, and overall they did okay. A few months later I tried repotting mature plants, and lost about 25% of them. They had very small, thin roots which I think were easily damaged. However, I didn't use a humidity tent in the process, so I don't know if that would have improved survival rates.

- media: Standard 1:1 peat and sand, although they also did fine in long-fiber Sphagnum moss.
- light: As much as you can provide. Plants can turn deep, striking red in high light.
- water: Tray method is appropriate, doesn't mine the tray occasionally drying out.
- temperature: Staying above freezing is important. I also noticed some heat stress in the middle of summer when temperatures were around 90 F (32 C).
- feeding: Regular feeding is important when plants are seedlings. If they are allowed to set a lot of seed without being fed some plants may die back a bit. Less food does mean more red color though.
- propagation: Easy to start from seed, high seed set when mature. In a colder climate this plant could act as an annual. No experience with leaf cuttings; root cuttings would probably not work.
