Anthurium Care Guide

You can use a rich, well-draining potting mix to plant the anthurium. Anthurium, bromeliads, and air plants are epiphytes that can grow without soil. They grow on the tree limbs and absorb the moisture from their roots. It is also advised to provide a trellis or moss pole for extra support because many varieties are climbers.

Creating a potting mix for this pink anthurium is very easy. You can combine half sphagnum moss and half fir bark which can hold the moisture even though it still allows the water to drain freely. If you don’t have this combination, you can try the orchid bark or perlite mix. Make sure to water the anthurium so you will see the mix is consistently moist.

As you see the anthurium grows, you will see aerial roots, or crown growing from the base of the plants. It is important to wrap the crown in a handful of sphagnum moss to keep moist.

Apply it every two weeks during the spring and summer seasons.

Meanwhile, a temperature below 65 F can slow down the growth and turn the leaves yellow. This plant cannot tolerate freezing conditions. They do best in 65 to 90 degrees Fahrenheit.


Fertilizer for this plant is not always necessary, but proper fertilizer can help the plant to thrive. A proper fertilizing schedule is once a month during spring and summer.
