At some point, you might also want to propagate your Alocasia wentii plants. It gives you more plants to grow. Furthermore, it is also a good method to keep this plant healthy. Now, if you want to propagate this plant, there are three methods you can use.

Make sure you prepare the soil mix in the pot with enough nutrients and plant it carefully. The growing process could take up to 10 days. Water the plant regularly and it will develop it’s roots naturally and gradually grow. Then, you don’t need to buy another Alocasia from the store.

  • Water Propagation

Water propagation is the best choice if you want to have more control over the cutting growth. The method is similar to soil propagation. Make a proper cut on your Alocasia wentii with a sterilized knife. 

However, rather than wait for the cut to dry, you dip it in water. Make sure only some part of the plant submerged in the water. For better results, put around four inches of the cutting in the water. The remaining parts of the cutting should stay above the water level. 

You also should change the water regularly. It keeps the bacteria gathering in the water and attacks the cutting. The time until the cutting is ready to plant is similar to the soil propagation. It takes less than ten days. You will see the root start to develop during that time. After the root system become much more mature, you can transfer the cutting to the soil that you have prepared before.

  • Stolon Propagation

You also can collect the stolon before it grows into clumps with the mother plant. Then, use the water propagation method to stimulate growth. Water propagation is the best method for stolon because, at that stage, the roots are not fully developed. So, the water method is necessary to boost its growth, plus monitor the sign of rots. That way you can prevent any damage that could happen because of that.

If it takes too long to develop a proper roots system, you can dip the stolon in the rooting hormone liquid first, before you plant it in the soil. Make sure the soil is fully fertilized, so it can help the stolon to grow roots, and then grow bigger into mature Alocasia wentii plants.
