Hi Guys I have had feed back from my overseas supplier with reference to the plants that have few or no roots at all, Microsorium, Cryptocoryne & Glossostigma. Just plant the plants into your substrate and with goog lighting , new roots will grow. Microsorium has been removed from the mother plant with few strands of root, attach to bog wood and it will grow. If one sees the plantlets on the Microsorium (Java Fern) leaves, that is how Java fern is propogated. Any other questions is most welcome.
