Once M. umbrosum's basic requirements are met, it becomes an extremely easy plant to propagate. Simply cutting the plant at any point along a main stem and planting it in the substrate will shortly result in new roots and a separate plant. M. umbrosum tends to produce new stems at a fairly high rate. New stems form at the base of leaves a few inches away from the growing tip and can be promoted to form by pinching off the growing tip itself. Fairly dense patches of M. umbrosum can be produced by encouraging new stems to sprout in this way. Emersed propagation can be achieved, but high humidity and a wet substrate are required; if those conditions are met, it can be quite vigorous.
M. umbrosum is normally used in an aquascape toward the middle or back of the aquarium. With extremely high light, it may be coaxed into growing prostrate in the foreground.
