Alocasia Macrorrhizos Care

15 - 24°C
Direct Light


Alocasia Macrorrhizos plants prefer warm temperatures between 60°-80°F (15.6°-26.7°C). These plants become dormant with prolonged exposure to temperatures below 60°F (15.6°C) and may drop all of their leaves. Be sure to keep an Alocasia plant away from air conditioners and cold drafts. During warm summer months, and Alocasia Macrorrhizos can produce a new leaf every week, and each new leaf maybe twice the size of the previous leaf.


An Alocasia Macrorrhizos requires very bright indirect light but no direct sun.


Maintain a regular watering schedule and keep the soil of your plant moist, but not wet or saturated. This is not a drought-tolerant plant, but it is relatively forgiving if you forget to water it from time to time. Extended periods of dryness can result in brown leaf tips or edges. Root rot will occur if the soil is allowed to become soggy.


Alocasia Macrorrhizos love extra humidity. Mist your plant on a regular basis, place a humidifier nearby, or use a pebble tray to increase humidity. Your bathroom or kitchen are perfect spots for your Alocasia Macrorrhizos because these areas tend to be more humid.


Use an organic well-aerated loose soil that contains a good amount of peat moss. If the soil seems a little heavy, add some builder's sand or perlite.


Via Seed, Stem Cuttings (only for mature specimens), or Basal Offset Division.


This plant is classified as poisonous due to varying concentrations of calcium oxalate crystals found around the plant's body. If parts of the plants are eaten, vomiting, nausea, and a loss of appetite could occur. Consumption of large quantities must be dealt with quickly; acquire medical assistance for further information.


Feed twice a month in the growing period and monthly in the autumn and winter to replicate its dormancy period. Either use a houseplant-labelled feed, or a general plant fertiliser at half the recommended strength. Never apply a 'ready to pour' feed without a quick drink beforehand as the combination of dry soil and harsh chemicals may lead to root burn and yellowed foliage.
