Feed Alocasia reginula with a balanced water-soluble fertilizer every 4 weeks during the growing period. Withhold feeding during the cold season as the plant undergoes dormancy during this period and growth is minimal at this time.

Regularly flush out accumulated salts arising from fertilizers every 2-3 months for your Alocasia reginula by running a stream of water through the soil until the water comes out through the drainage holes. Let the stream of water run for a few minutes. Repeat the process several times. Read more on how to feed houseplants.
