And if it feels dry, don’t hesitate to water your plant again.

Fertilizing Alocasia Regal Shield

If you live in a cold climate, you can start your Alocasia Regal Shield plants indoors and then move them outdoors once the weather warms up.

As a result, your plant will lose some of its leaves. Alternatively, they may also develop undesirable crisp edges. The good thing is that you can reverse these effects by moving the plant to an area without direct sunshine.

Fill your pot with well-draining soil, and then dig a hole twice the size of the root ball. Gently place your plant in the hole and then fill in around the roots with soil. Water your plant well, then put it in a location that receives bright, indirect sunlight.

How to Grow Alocasia Regal Shield From Seeds

Although Propagating Alocasia is much easier than division, it is still possible to grow them from seeds. The process, however, is a bit more delicate and will require more attention than propagating through division. To grow Alocasia Regal Shield from seeds, follow these steps;

Step 1

First, you will need to find fresh seeds. The best way to do this is to purchase them from a reputable source. You can also collect the seeds from a mature plant, but be sure they are ripe and ready to be harvested.

Step 2

Once you have your seeds, fill a pot or container with a sterile seed starting mix. Moisten the mixture, and then sow the seeds on the surface. Please do not cover the bases with soil, as they need light to germinate.

Step 3

Place the pot or container in a warm, sunny location. The ideal temperature for germination is 75-85 degrees Fahrenheit. Keep an eye on the soil, as it will need to be moistened regularly.The seeds will germinate in four to six weeks. Once they have sprouted, you can transplant them into individual pots. Be sure to use a pot at least 12 inches wide and 12 inches deep.Water your plants well and place them in a location that receives bright, indirect sunlight.

Repotting and Growing in Containers

Once you have grown your Alocasia in a large pot, it is time to repot it into a larger pot. Look for a large container with drainage holes in the bottom that is twice as wide and deep as your current pot. Mix good quality organic soil with some organic fertilizer of choice. For example, mix four parts of Happy Frog All-Purpose Planting Mix with one part of hydrated Happy Frog Water Soil Moistener, which will contain nutrients that plants like alocasia need. Fill your new container with this mixture until it is an inch or two from the top and then carefully remove your Alocasia from its old pot, using care not to uproot any roots on the way out. Keep in mind that a general rule for most houseplants is to place them approximately 1 foot away from a window to get ample light. We also recommend using distilled water and feeding your Alocasia once a month with a fertilizer. We hope these tips will help you care for your Alocasia.

Best Placement in Your Home

Alocasia is a more ‘tropical’ variety of houseplants. They love the warmth and humidity and do best in indirect or filtered sunlight. As with all houseplants, invest in a good-sized container for them to grow. A pot made from something other than plastic will also help drainage, which may be an issue as these plants don’t like sitting in their water or having their leaves constantly wet.

Pruning, Cutting Back, Cleaning Up

Alocasia plants are easy-for-care plants that can be enjoyed indoors year-round. Alocasia enjoys bright but indirect light. Prune as needed, using sharp scissors and take care not to cut too far into the woody base of the plant. When trimming alocasia roots or old leaves, do so with sharp pruning shears or scissors. Make sure you don’t pull on a stem or let it snap off, which may damage it. Clean up any leaf litter periodically by taking off dropped leaves (especially before they form soil crust) with a rake or scooping up as much as possible with your hands.

When will my alocasia flower?

The Alocasia Regal shield house plant may take a few years to produce a flower. For best results, grow the plant in pots with enough room for both roots and leaves to flourish. As soon as your plant reaches about 15 inches high and wide, pot it up again to accommodate its rapid growth pattern. This is when it will most likely produce flowers.

Are there other plants that look similar to my Alocasia?

The Alocasia Regal Shield house plant does look similar to other plants, but it is easy to tell if you know what to look for. Some gardeners will mix up an alocasia with a Xanthosoma or another type of ornamental plant because they can look similar in full bloom. The problem is that these plants grow from a bulb and are not Viney, whereas an alocasia is Viney and usually grows from a rhizome.

How can I propagate (make more) plants from my alocasia plant?

According to Plantphiles, plant division is the best approach to propagating Alocasia Regal Shield. One easy way to reproduce an alocasia plant is by cutting a leaf off and sticking it in water. Roots will eventually form on the cut end, and new plants can be pulled up as they grow. Alternatively, you can also root cuttings in moist soil or sphagnum moss. In many cases, propagation is most successful during the time of year when plants are not growing (such as in winter) because this slows down their metabolism, allowing more energy to produce roots instead of leaves.

If you have read this guide carefully, it is time to begin your journey with Alocasia Regal Shield. Use these tips to ensure that your project goes to plan. And after some time, you will appreciate your newly learned gardening skills.
