Hygrophila corymbosa is an undemanding starter plant that originates from Asia. In the aquarium it will spread fast and create bright green, long and wide leaves.
It is a fast growing plant that must be pruned frequently. New shoots will spread from the stem and make the plant look bushier. The cuttings can be re-planted in the bottom of the aquarium where new roots form quickly. 
A bundle of stems or young plants gathered in an anchor. Remove the anchor and split into separate plants. Regarding stem plants, remove the leaves from the lowest 5 cm (2“). Remove any damaged leaves. Plant the individual plants with some distance into the bottom substrate. Roots will develop soon and the plant start growing.
