Water your Dumb Cane biweekly, as it enjoys staying moist. During the growing season, ensure that the plant stays moist, and reduce the amount of water that you provide it during the winter months.
To check the water levels of your plant’s soil, place a water meter several inches into the soil, where it will give you an accurate indication. If you do not own a water meter, stick one finger knuckle-deep into the soil. At this depth, you will be able to accurately account for the soil’s level of moistness.
