How Often Should You Water Lucky Bamboo?
A healthy lucky bamboo depends on the right watering method. Learn the correct techniques for plants grown in water or soil and what water to use.
Lucky bamboo (Dracaena sanderiana) is a resilient and popular houseplant. While low-maintenance, its health is directly tied to receiving the correct amount of water. Proper watering frequency and technique depend on whether it is grown in water or soil.
Watering Lucky Bamboo Grown in Water
The most common method for keeping lucky bamboo is growing it in a vase of water. The water level should be high enough to submerge the roots, about one to two inches from the base of the stalks. Top off the water every few days to maintain this level as it evaporates.
Stagnant water can lead to the growth of algae and bacteria that harm the plant. To prevent this, change the water completely every two to four weeks. This involves removing the plant, discarding the old water, rinsing the container, and refilling it with fresh water.
The type of water used is a factor in the plant’s health, as tap water can contain chlorine and fluoride. For optimal health, use distilled, filtered, or rainwater. If tap water is the only option, let it sit out for at least 24 hours to allow the chlorine to dissipate, though this method does not remove fluoride.
Watering Lucky Bamboo Grown in Soil
When lucky bamboo is potted in soil, the goal is to keep the soil moist but not waterlogged, which can lead to root rot. To determine when to water, check the soil’s moisture. Insert a finger about an inch into the soil; if it feels dry, it is time to water.
Relying on the soil check is more effective than following a rigid schedule, as conditions like temperature and light exposure affect watering frequency. When it is time to water, do so thoroughly until water seeps from the pot’s drainage holes. This ensures the entire root system receives moisture.
After watering, discard any excess that collects in the saucer. Allowing the pot to sit in standing water negates the benefits of well-draining soil and can suffocate the roots, leading to decay.
Signs of Improper Watering
Yellowing leaves or stalks often point to a problem with water quality, such as chlorine and fluoride in tap water. For plants in soil, yellowing can also be a symptom of overwatering.
Brown, dried-out leaf tips are another common sign. This can be caused by chemical burn from tap water, dry air, or inconsistent watering where the plant goes through periods of being too dry and then too wet.
Soft, mushy stalks are a sign of decay. In water, this is caused by bacterial rot from infrequent water changes, while in soil it indicates severe overwatering and root rot. A wrinkled or shrunken stalk is a symptom of underwatering and dehydration.
