Outdoors, it performs best in filtered light or morning sun with afternoon shade. Too much strong sunlight—especially harsh afternoon rays—can scorch its dark leaves, causing crispy edges or discoloration. Indoors, place it near an east- or north-facing window where it gets bright but gentle light. If lighting is low, the foliage may become smaller and less vibrant. For terrace or balcony gardens, use a shade-net setup for optimal growth.\u003c\/p\u003e\n  \u003chr\u003e \u003ch3\u003e\u003cstrong\u003eWatering and Humidity\u003c\/strong\u003e\u003c\/h3\u003e \u003cp\u003eAs a tropical plant, Colocasia loves \u003cstrong\u003econsistent moisture\u003c\/strong\u003e, but not waterlogging.
