Light Needs

Give it plenty of indirect sunlight. But try to avoid direct sun. They grow best with as much light as you can give them but without giving them direct sunlight which can burn them. I would put them off to the side of a south facing window so they do not get the direct sun.

How Often To Water An Alocasia Regal Shields

Check the soil of your alocasia regal shields every week with your finger and only water it if the top 50% of soil is dry.

Tip: keep them moist but not soaking wet. So check them weekly and water if the top half of the soil is dry. Tip out any excess water afterwards to avoid water logging so you keep them moist without drenching.


Feed your plant a balanced fertilizer every 3 weeks in spring and summer, you do not need to feed it in the winter. I would use a well diluted feed for the first few times you feed them in the season to avoid fertilizer burn.


A rich well draining potting compost is essential, I would use a mix of orchid bark, potting compost and perlite in equal parts, which will work well. For more on which soil to buy or how to make your own see our guide: Alocasia Soil.

When To Repot

Check them yearly to see if the roots are crowded and pot them up a size if needed. The best time of year to do this is in spring, before they start to grow for the year.


60% is ideal, they really like it humid. The leaves can crisp up if not given enough, so at the very least keep them next to other plants which can increase the local humidity.

Tip: Keep them humid, aim for 60% in the day and they’ll be ok with a bit less at night. You can buy a humidity meter (affiliate link) to keep an eye on maximum and minimum levels.


A good range is 15-30°C (59-86°F during the day, so they’ll be fine in most homes as long as you don’t let them get too cold. Try to make sure they do not get below 12°C (54°F) too often.

Alocasia Regal Shields Propagation

The best way to propagate an alocasia regal shields is with separation at the roots. You’ll need a plant that has a small pup at the base, and is already dividing into more plants.

Follow these steps to propagate an alocasia regal shields:

  1. Take the plant out of it’s container and get rid of as much soil from the roots as you can, carefully.
  2. Find the pup that you want to separate out, and very carefully pull it away from the plant plan.
  3. It is important to make sure the new plant comes away with it’s own root system. Try to limit damage to the roots as much as you can.
  4. Let the plant’s wounds heal for a few hours.
  5. Plant each plant up separately.
  6. You’re done!

Alocasia Regal Shield Drooping

Both over watering and underwatering can cause drooping. If you water the plant well (check it regularly, but only water it if it needs it) you should avoid both these issues. If the plant is drooping due to root rot, and the soil is wet, take it out of it’s soil, and let the roots dry for half a day, then pot it up in dry soil. If you have any smaller plants growing round the base you can separate them out at this point, in case the root rot takes hold.

Dropping can also be caused due to too much sun, so make sure the plant is not exposed to full sun.
