Propagation of Anthurium Watermaliense is simple: this plant can be grown in water or soil. 

In order to propagate your Anthurium Watermaliense through stem cuttings, follow these steps:


Step 1: Cut a piece of stem

The first thing you do is prune off a stem from your main Anthurium Watermaliense. It’s your call how far down you wish to cut off the stem. 

The amount of stems you cut depends on how many new Anthurium Watermaliense you want to grow.

You can trim until the level of the potting mix if you want to. 

The plant won’t die because of this cut, and eventually, new leaves will sprout from the cut area.


Step 2: Clean the stem and prune excess leaves

Take your stem cutting and remove all the brown and leaf-like husks that are on your stems. These husks are known as stipules, and it only there to protect new emerging leaves. 

Your new plant will not initially need it; thus, removing anything that takes up extra nutrients is best.

Prune away old and yellowing leaves. If any flowers are present, prune those off as well.

One cannot maintain Flowers during a propagation process. They could eventually kill off your new plant as it is not yet well-grown, and flowers need a lot of energy to grow.


Step 3: Count the nodes

The number of cuttings you take from your main Anthurium Watermaliense depends on you. But make sure that each stem cutting will have a minimum of two nodes. 

The longer each stem is and the more aerial roots it grows, the more likely your plant will survive a long time.


Step 4:Treat the stems cut ends

You can put rooting hormone at the stem’s cut end. This step is optional as your plant will grow well even if you do not treat it.

Rooting hormone chemicals are available in the form of a powder, and you can dip the cut end into the powder. Then you can place it into a growing medium.

You can even purchase the liquid rooting hormone if you are rooting your new Anthurium Watermaliense in water or perlite. 

Just add a drop or two of it into the water or perlite, and this should help your plant root faster.


Step 5: Planting the stem cuttings

You can now plant your stem cutting in water or a soil substrate that has perlite. You will have to bury as much of the aerial roots beneath the soil.

If the stem does not have leaves or roots, make sure at least one root’s beneath the soil. 

You must also make sure that the second node remains above the ground so new 

leaves can emerge from it. 

The more the node, leaves, and aerial roots present on a stem, the better your plant will grow.


Step 6: Cover your new plants up

Covering your new plants with a plastic sheet will help increase the humidity levels around your Anthurium Watermaliense.

A plastic tub with a locking lid on it in lieu of a plastic bag is also another option. This helps keep the moisture inside your plant.

Step 7: Wait for your new Anthurium Watermaliense to grow

Anthurium Watermaliense will take a few weeks to show some new growth. It can take at least five to six weeks for you to see any new leaves or roots forming.

With enough time and proper plant care, your new Anthurium Watermaliense will thrive just like your main Anthurium Watermaliense plant.
