Aldrovanda in Indonesia

[rsivertsen]

I would avoid using any peat, as it seems to promote algae blooms, and lowers the pH too much; in my outdoor pond they grow best in areas where there is a lot of clay, (pH=7.0), and leaf litter from Phragmites, Carex, Typha, and Juncus plants, sometimes in less than 5 cm or water, (or out of water all together for a while).

Perhaps some of the "burnt earth" might help, as it's some form of a clay based substance. The important part is the root systems of large monocot companion plants, and being in close proximity to them. Also, the population density of the zooplankon is higher, more concentrated in shallow depths. Growing Aldovanda in too deep conditions was my problem too when I first started growing them. - Rich
