I seem to have really bad luck growing any of the Drosera in the petiolaris complex. I live in South Florida...so my conditions are right. I grow them in full sun and sit them in trays of water. Anyone have any pointers? I notice that they tend to get algae on the surface of the soil more than any of my other Drosera. It looks like it chokes them a bit. But I don't like repotting them because they don't like it. I would appreciate any advice.
