Alocasia Regal Shield Care
This plant is easy to care for once the basics are understood. They like bright sunlight, constant moisture, high humidity, soft soil, and warm temperatures throughout all seasons. They also like space.
Alocasia Regal Shield Soil
Loamy, organic soil is essential for proper care of Alocasia Regal Shield. Alocasia Regal Shield care is best done in soil with a lot earthworm activity.
The soil must be well-drained, moist, nutrient rich, and slightly acidic. Your Regal Shield roots must have oxygen otherwise they will rot and become dead.
Wet, clayey or muddy soil will stick to roots and prevent them from breathing. Give the soil a good squeeze. If the soil becomes a lumpy mass, it is not suitable for growing Alocasia Regal Shield.
Too dry or sandy soil won’t retain enough water.
Alocasia Regal Shield prefers soil pH between 5.5 to 7.0. You can add garden compost, organic manure and mulch to the soil. The soil will be more acidic if you add organic manure, mulch, and garden compost.
Watering Alocasia Regal Shield
Alocasia Regal Shield is best grown in moist soil. This plant is tolerant to some dryness from time to time, but most growers recommend that you dry the soil.
This is not true for Alocasia Regal Shield. I water my plants every other day during the summer months, when temperatures range between 25-30degC (77-86degF). This cycle is very beneficial for the plant, even though it may sound a bit excessive. My soil is extremely porous so the water runs out in 20 seconds.
The top soil test is the safest gauge. This method is reliable for most aroids. You can water again once the soil’s top two inches dry out.
One Alocasia Regal Shield tip is to be aware of signs that the leaves are being overwatered. The tips of the leaves will drop water and droop.
In cold weather, I reduce the amount of watering. Overwatering in winter can make the plant susceptible to root rot.
Alocasia Regal Shield Light
Alocasia Regal Shield needs 70 to 85% sunlight, but not direct sunlight. They thrive in indirect light. A 40% shade cloth is ideal if you wish to grow Alocasia Regal shield outdoors.
Given its size, indoor growing is possible. Place it in an east or west window location. It can be placed behind sheer drapes to filter the sunlight.
Alocasia Regal Shield grows in the direction of light. For a well-rounded growth, rotate the pot at least once a week.
This plant can be used in patios, rather than indoors or outdoors. These semi-outdoor areas are generally well lit for Alocasia Regal Shield care.
Too little light can cause the leaves to become dull and slow growth.
Alocasia Regal Shield Humidity
Alocasia Regal Shield must be grown in high humidity. You won’t be disappointed if you plant them indoors under dry desert conditions.
Anything above 80% is fine. To keep your plant hydrated, you can use humidifiers, pebble trays, and occasionally misting the leaves with a damp cloth.
Even better, you can grow juvenile plants right next to your bathroom window. You will be able to make them feel warm and fuzzy in there.
Alocasia Regal Shield Temperature
Alocasia Regal Shield thrives under tropical conditions. They rarely go into dormancy in the tropics. Their ideal daytime temperature hovers around 25degC (77degF).
If you want to grow Alocasia Regal Shield as a tropical evergreen, ambient temperatures between 20 and 30degC (68-86degF) are ideal. If they are exposed to frost, the corms should be replanted in spring.
They may lose their leaves if they are exposed to low temperatures for more than 60 degrees F (16°C).
Fertilizing Alocasia Regal Shield
Alocasias are heavy feeders. Alocasia Regal Shield can be grown in a pot. However, the soil and nutrients will be very limited as it matures. You must feed your plant regularly, especially if you want them to reach their full potential.
For Alocasia Regal Shield you need to be sure that the soil is rich with organic nutrients. Use good quality sterile compost or animal dung manure.
You can then apply a dilute liquid fertilizer on a monthly basis, reducing the concentration to one-third of what is recommended. This must be done during the growing seasons of spring and fall to ensure proper care for Alocasia Regal Shield.
Be careful when using cheap fertilizers. Salt buildup can cause your plant to die. You should also water your plant well the day after fertilizing it.
The main method of Alocasia Regal Shield plant propagation is division. The rhizome can be divided or the clumps located at the base. There will be many plantlets at the base, which you can also separate.
