What do you do with the roots off stem plants that come from the stem above the substrate? My hygro bushes has tons of these roots high on the stem first they came through white but after a while they turn cream and not many leaves from half way down the stem just roots.

Non obligate aquatic plants can grow under water or out of the water. We keep then growing under water by taking top cuttings and replanting in the tank's substrate. Often there will be regrowth from the lower rooted portions.

Loss of lower leaves tends to be a fact of life. Some say its lack of light others lack of nutrients due to reduced water circulation.

Lots of stem plants produce roots at their nodes. If these plants where lying on wet mud in a humid atmosphere each rooted node would produce a new upright shoot its just how these plants grow. Could be worth a play at propagation from the sections most people throw away when they replant top cuttings.
