In winters, this Jewel plant stops growing and goes dormant. It does not need any fertilizer in this resting stage. If you are not feeding this plant enough, it will shed all its leaves and go dormant, even in the growing season. You should properly schedule its feeding frequency to bring it back to life.

Alocasia Melo Care

This easy-to-care tropical plant needs to be watered twice every week. It must be grown in well-draining soil, having a pH level of 5.5-6.5. The ideal temperature range is 20°C-30°C. The humidity must be around 75%. It needs monthly feeding with a domestic fertilizer. The best growth zones are 10 and 11.

Water Requirements

This tough beauty makes a great fuss if it is overwatered. Its roots do not like standing water. This plant prefers to be kept dry between waterings. You can schedule its watering days by the general rule of thumb. Insert your index finger into the soil. Do not water the plant until the 2 inches of the topsoil is completely dry. It takes more days to dry completely in winters. As per its requirements, you should water this plant twice a week in summers and once a week in winters.

Soil Requirements

The pH level of the soil is a significant determinant of nutrient availability. Slightly acidic soil makes sure that a sufficient amount of nutrients are taken up by the soil. The optimum pH for Alocasia Melo’s soil is 5.5 to 6.5. This pH level can be regulated by spritzing the soil with diluted vinegar.

As this plant does not like standing water, you should use a potting mix that has good drainage. So the excess water drains out of the pot. You can add a little perlite or sand to the sand to increase its drainage and aeration.


This jade-green Alocasia might seem so tough and hard, but in reality, it is really sensitive. It cannot tolerate direct sun. It must be placed in a spot where it receives indirect sunlight. Partial shade or artificial light is also suitable for its proper growth. Growing this plant under artificial light does not mean that you grow it in low-light conditions; its leaves require bright light exposure to carry out photosynthesis. You should place this peep at least 15 inches away from the bulb so that it can receive the required light exposure.

Temperature Requirements

Alocasia Melo prefers an environment that is warm and humid.  It prefers temperatures between 20°C and 30°C. As long as your room temperature stays in this range, this plant will flourish. It does not like to be grown in temperature extremes. On a hot day, you should compensate for the temperature by misting the plant. Misting will increase the rate of evaporation from its leaves, so eventually, the temperature around this plant will drop. You should never place it in the way of cold or hot drafts.


The thick leaves of Alocasia Melo lose their color and freshness if there is not a sufficient amount of moisture in their surrounding air. This plant loves high humidity. The ideal humidity level for this plant is 75% during the day and about 95% at night. This humidity level is quite high as compared to the regular household humidity. That is why you should try different tricks to increase the moisture level inside your home so that this plant stays happy and fresh.


This Alocasia rugosa is not a heavy feeder. It does not need to be fed every now and then. You should only fertilize it once a month in the growing season. No need to add any fertilizer during winters and fall as the plant is pretty much dormant in these seasons.

The common household fertilizer will do fine for its proper growth. However, dilute the fertilizer before adding it to the soil. It must be diluted to 1/3rd of its strength. Make sure the fertilizer has the appropriate amount of NPK (nitrogen, phosphorus, and potassium).

Grooming and Pruning

Every houseplant needs yearly pruning to keep it in the perfect shape and appearance. Alocasia Melo also needs to be freed of old leaves at the beginning of each growing season. You can prune your plant on your own by using a sharp pair of shears. Never forget to sterilize the shears before pruning; this will protect your plant from any infections.


This artificial-look alike plant likes to stay root-bound. It should not be disturbed unless its roots start to grow out of its drainage holes or it outgrows its own pot. If you see any of these two signs, surely re-pot your plant, otherwise keep it as it is. If you are re-potting your plant because it has grown bigger for its present pot, you should move it to a new pot that is almost 2 inches bigger.


Re-potting and propagating Alocasia Melo at the same time is like killing two birds with one stone. You can propagate it through rhizome division at the time of re-potting. Let us explain it to you through simple steps:

  1. Take out your Alocasia plant from the pot and shake off its soil.
  2. Take a sharp blade and cut a 1/3rd part of a healthy rhizome from the roots.
  3. Now take new pots. Put rhizome in one pot and its mother plant in another one.
  4. Fill both pots with potting mix and water them thoroughly.
  5. Place them in warm spots where they receive bright, indirect sunlight.
  6. In 4-8 weeks, both plantings will come out of stress and will start growing.
