That’s…pretty much it. They must be kept in non-porous pots and trays (glass or plastic), water TDS must be below 50 ppm and keep water in the tray constantly. They will even bloom with gorgeous little flowers. No fertilizer ever, just bugs.
I can’t emphasize enough a sunny spot. This window faces southwest and so it gets 8 hours of direct sun. This helps with growth and also makes the mucus shine which seems to attract the bugs.
I’d stay away from terracotta long term but if it’s working for you, play ball.
Why no terra cotta? It’s pretty high quality and isn’t leaching minerals or anything.
It does leach minerals over time. Sundew seem to be less picky than some other carnivores in this respect, I’m just passing on what works for me. The worst possible outcome of choosing the wrong material is ya kill a $14 plant so it’s pretty low stakes.
Well I’ve got several large drosera and a ruby red flytrap in the same pot that have all been doing well for a long time. It’s a high quality pot that’s wide and shallow
I’ve seen a pot like that was a prefilled carnivorous garden, and the inside of the pot was glazed.
