Welcome to out guide to Alocasia Wentii care. Also known as the ‘New Guinea Shield’, it is a large alocasia which can grow really glossy red-backed green leaves up to half a meter (20 inches) in size. It is really similar to the more standard elephant ears, but my favorite thing about this plant is the glossy texture of the leaves and their size.

Alocasia Wentii Humidity

This plant will do best in 60% humidity, which is at the high end of normal households. But they will do fine in lower levels. Keep them in more humid areas of your home when you can.

Tip: Get a humidity meter to monitor the temperature and humidity (they give maximum and minimum read outs so you know if they are falling off at night). They’re really cheap these days, under 10 euros / dollars.


15-30°C (59-86°F) is ideal. Just don’t let them get down to below 5°C (41°F) for too long in the winter as cold can damage the plants.

Propagating Your Alocasia Wentii

The best way to propagate this plant is to wait for it to ‘pup’ (grow smaller plants at it’s base) and then divide them at the base and repot them up on their own. Follow these steps:

  1. Take the alocasia out of it’s pot.
  2. Brush as much of the soil off the roots as you can.
  3. Gently take the pups away from the main plant, making sure to do as little damage as possible, and taking some of the roots with them.
  4. Leve them for half a day for the wounds to callous over.
  5. Then pot them all up in separate pots of their own and water them in.

Done! Just make sure you are careful and try to keep the roots as intact as possible.
