Alocasia Hilo Beauty Soil

The Alocasia Hilo Beauty requires airy, well-draining, slightly acidic soil that has the ability to retain water. A 1:1:1 mixture of peat moss or coco coir to coarse sand and potting mix will be perfect for this plant. Keep the soil moist at all times as this plant likes consistent moisture rather than allowing the soil to dry out completely.

Alocasia Hilo Beauty Fertilizer

As this Alocasia grows extremely large and may be considered a heavy feeder, it requires frequent feeding throughout the growing season to remain healthy. Select a balanced liquid fertilizer with an NPK ratio of 20-10-10 and feed monthly throughout spring and summer, ensuring that you follow all label instructions. Do not overfertilize or feed in the winter, as this may cause issues, such as chemical burn. If you see signs of over-fertilization, stop fertilizing immediately.

Alocasia Hilo Beauty Watering

As a tropical plant, this Alocasia likes to remain frequently moist but not oversaturated with water. Overwatering can cause severe damage to this plant. The top 1-2″ of soil should dry out before rewatering. Watering frequency should be reduced in winter. Overly soggy soil may make this Alocasia susceptible to fungal diseases. 

Alocasia Hilo Beauty Light Requirements

Like many other tropical plants, ‘Hilo Beauty’ likes to have access to bright indirect sunlight throughout the day, emulating the dappled sunlight they might receive from the forest floor of a tropical region such as Hawaii. Direct sunlight should be limited to the morning hours, as too much direct sun will cause leaf scorching. Light from a southern-facing window is perfect for this plant. 

Alocasia Hilo Beauty Temperature & Humidity

As this plant hails from a warm tropical region, it likes to be grown in similar warm and humid environments. This Alocasia favors above-average temperatures above 85 degrees Fahrenheit. One of the most important factors playing into the success of growing this plant is keeping it warm. If temperatures go below 80 degrees Fahrenheit, this plant has a tendency to go relatively dormant. This plant will suffer damage if exposed to temperatures below 60 degrees Fahrenheit. Still, some varieties have the capacity to die back during colder weather and then begin regrowth after warmer temperatures.

Additionally, this plant requires a very humid environment and above-average home humidity levels. Therefore, raising your home’s humidity is imperative to growing this plant. Installing a humidifier or pebble tray is suggested. However, misting this plant is not recommended, misting doesn’t do too much to raise humidity levels and some plants do not like getting their leaves wet. Keep this plant away from AC units, heaters, drafts, and cold windows to avoid sudden temperature fluctuations.

Repotting Alocasia Hilo Beauty

Alocasia Hilo Beauty should be repotted every few years when roots are seen sticking out from its container’s drainage holes or you can see the roots on top of the soil. Always go one size up when repotting your plant, which is usually a pot that is 2 inches bigger in diameter. For example, if your Alocasia is in a 4″ pot, go to a 6″ pot when it’s time for a repotting. Going too much bigger in size may induce dormancy because it’s a lot of room for the roots to expand and it will take much longer to produce foliar growth.

Alocasia Hilo Beauty Maintenance & Pruning

This Alocasia does not require much pruning. However, to maintain your plant’s health, any discolored, diseased, or dead leaves should be removed periodically as needed. In addition, ensure that you utilize clean, sterilized shears or a sterile blade to prevent the spread of disease. 

Alocasia Hilo Beauty Propagation

Alocasia Hilo Beauty may be easily propagated through either rhizome division, offsets, or stem cuttings. Propagation should be done in spring to allow the new plant babies to grow during the active growing months.
