Alocasia Regal Shields can be picky when it comes to watering needs. You have to be careful not to overwater them or underwater them. Allow the top two inches of soil to dry out, but don’t allow all of the soil to dry out before you give it more water.

If your Regal is growing new leaves it will need to be watered more often. If you notice new growth check the soil moisture at least every other day during this time to ensure that it has the proper moisture levels. Without enough or with too much water you will lose the new leaf that is growing.

Lighting Needs

The Alocasia Regal Shields can do well in medium to bright indirect light. It can tolerate some sun, morning or late evening sunlight is best.

If you notice that your Alocasia is starting to look too leggy or is leaning too far towards the light then you want to move it to a location with more light.

Rotate your Regal Shields plant regularly so that it will not lean over to one side towards its light source.

Alocasia Regal Shields Soil Mix

Well-draining soil is best, but you want a good balance between draining well but also retaining some moisture.

Some options for good soil mixes would be a make your own with equal parts potting soil, orchid bark, perlite, and worm castings. You could also get a premade aroid soil mix. Another option is that you can combine 1 part succulent soil with 2 parts regular potting soil.


Your potting choices for Alocasia Regal Shields vary greatly and it all depends on your watering style. If you tend to overwater your plants then terracotta would be a good option, if you underwater them then it would be best to stay away from terracotta. Other than that you can use standard ceramic or plastic plant pots. Just make sure that the pot you pick out has drainage.


Alocasia Regals tend to prefer smaller pots compared to the size of the plant.

Once you see roots coming out of the existing pot then it is time to repot your Regal Shields. If your plant is dropping leaves with no signs of pests that could be another indication that it needs repotting.

The best time to repot is in the spring.


During the spring and summer months, fertilize your plant once a month with any all-purpose houseplant fertilizer at half strength.

If you have just repotted your plant, skip a few months of fertilizing due to the plant food in most soil mixes.
