Fertilizer/ feed for the plant:Feed the arrowhead plant every 2 weeks with fertiliser diluted to half strength. Make sure the soil is moist at all times, but refrain from drowning him through overwatering.
Repotting : When you notice stunted growth or discomfort in the plant, it is time to repot into a bigger pot. Ideally, the Arrowhead plant is repotted every 2 years. He grows aggressively so the roots outgrow the pot and then it is time to repot and make them comfortable.
Propogation : It can be easily propagated via stem cuttings. Take cuttings with at least one node and root it in water. They root in water just as well, as they do in a potting mix. For a failsafe propagation, choose a new shoot that has sprouted a couple of leaves and has more than one aerial node
