Underwatering
Dry soil and yellow lower leaves usually mean it went too long without a drink.
Diagnosis
Underwatering
What's happening
Dumb cane has big, thirsty leaves and uses water quickly. When the soil dries out completely the plant can't keep its oldest leaves hydrated, so they yellow and go limp, often with crisping edges, while the soil shrinks and pulls away from the side of the pot.
How to fix it
Water thoroughly until it drains from the bottom. If bone-dry soil sheds water without soaking in, bottom-water instead: set the pot in a few inches of water for 20–30 minutes, then let it drain fully. From now on check the soil weekly and water once the top inch or two is dry — dumb cane likes evenly moist, never soggy and never bone dry.
What fixes it
- A long-spout watering can — A long-spout can makes it easy to water deeply and evenly down at the soil.
If that doesn't fix it
This is general guidance based on common symptoms; individual plants vary.
