Hello,
I managed to grow a few Drosera rotundifolia plants from seed.
They've been doing nicely outside under sheltered sunlight since their sowing (I'm in temperate zone so climate fits their needs), never kept them inside a dome (so that I wouldn't have to worry about mold) but always used an open tray filled with 1/4 inch (6mm) of water (TDS 18 ppm). The soil is pure blonde peat fit inside an icetray (with holes drilled in the bottom).
I just fed them with insects and watched them grow. My largest ones (shown in this picture) are about 2 inches (5 cm) in diameter leaftip-to-leaftip.
Fungus gnats did often fly above them and I watched sometimes small worms swimming (maybe their larvae) in the shallow water but they never seem to have bothered them in months.
Now all of a sudden the once oblique leaves flattened on peat and the center of their rosette somewhat turned brown.
What could it be? Could you please tell me how to save them?
Thank you
Alfred
