About Dumb cane
Dieffenbachia humilis, also known as 'Lalu', is an indoor plant from the Araceae family, valued for its large, oval leaves, often featuring attractive patterns of light and dark green. Its dense and lush foliage makes it an excellent focal point in living rooms, offices, or any space needing a touch of tropical greenery. It is ideal for medium to large pots, where its leaves can unfurl fully.

Care tips
Place it in a spot with bright, indirect light; direct sunlight can scorch its leaves. Water when the top layer of the substrate feels dry to the touch, avoiding waterlogging to prevent root rot. Use an organic-rich, well-draining substrate. A common mistake is insufficient ambient humidity, which can lead to brown leaf tips; mist its leaves regularly or use a humidifier.
