Anthurium plants don’t like continually moist soil. Make sure to water your anthurium plant regularly, but don’t over water. Only water your anthurium when the soil is dry to the touch. The plant is susceptible to root rot, so too much water can cause the roots to die. If you allow the plant to become too dry in a pot, it will slow down its growth and the rootball will be difficult to re-wet. If the rootball becomes too dry in the pot, soak the pot the anthurium plant is in for an hour to rehydrate it. 

Fertiliser
The plant only needs to be fertilized with a one-quarter strength fertilizer once every three to four months.
