– Incorrect Watering

Why is my outdoor bamboo turning yellow? The friendship bamboo or ribbon plant isn’t drought tolerant. If you grow it outside, you should water it regularly in mild weather and more often in hot weather. Lack of watering will cause the leaf tips to turn brown and crispy. Moreover, the stalks will become yellow because of improper irrigation.

At the same time, too much watering in poor-draining soil causes root rot. The plant will suffer, and the stalks will become yellow.

Indoor bamboo is usually grown in glass containers with a substrate like rocks and pebbles. You can also grow these plants in soil containers; in this case, the dry soil might cause the yellowing of the plant.

So, why is my bamboo stalk turning yellow in water? If you have indoor plants that grow in water-filled containers, you can still see that the lucky bamboo turns yellow. This happens when you don’t provide the plant with enough water.

In this case, the stalks might lose their green color and become yellow. Stagnant water can also be the culprit, creating a favorable environment for bacteria, mold, and other fungal diseases.

– Poor Water Quality

Why is my lucky bamboo leaves turning yellow and brown? The bamboo plant is quite sensitive to chemicals and water temperature. Using the wrong water type or watering your plant at the wrong time can cause the yellowing of the leaves and the stalks.

You might see your lucky bamboo turning to shades of yellow because you’re using cold water to water your plants. Tap water can also affect the color of the stalks because of the fluoride, chloride, and other chemicals. You might notice the changes overnight because the lucky bamboo can’t withstand poor water quality.

– Too Much Sunlight

Bamboo prefers bright yet filtered indirect sunlight, as this plant naturally grows under the canopy of giant trees in its native habitat. Seeing a yellow bamboo stalk might mean you don’t provide this plant enough protection from the sun.

Leaving the plant exposed without shelter will scorch the green leaves and cause the stalks to become yellow. This can also happen if you’re growing indoor lucky bamboo and leaving the vase or container next to a south-facing window.

– Environmental Stress

Bamboo is quite sensitive to changes in temperature and humidity. This plant prefers temperatures between 65 degrees Fahrenheit and 90 degrees, so if the temperature is too hot or too cold, you’ll notice it’s struggling. The stalks will become yellow, and the leaves will turn brown or dry.

The yellowing bamboo leaves can result from a change in the plant’s location. This is why seeing bamboo leaves turning yellow after repotting is quite common.

So, if you keep an indoor plant and suddenly move it outside, you’ll notice that the stalks are yellowing because they can’t handle extreme temperature changes. It might also happen if you keep an indoor plant beside the radiator.

You might also notice your outdoor plant turning yellow because of too much wind or pollution. This happens if you grow it in the wrong spot in your garden or don’t provide adequate protection.

– Overfertilizing

Bamboos aren’t heavy feeders; applying a drop of liquid fertilizer every few months is ideal to keep this plant healthy. As a matter of fact, many plants survive for years without any fertilizers. However, some homeowners see that their lucky bamboo plants are struggling, so they try to help them by providing more food as they attempt to save the plant and restore its green color.

This usually worsens the problem. Too much fertilizer leads to the accumulation of extra salt in the soil and water. As a result, the plant’s leaves and stalks will turn yellow.

– Pests and Diseases

Although lucky bamboo is easy-going and resilient, changes in its optimum care routine can cause the yellowing of leaves and stalks. Thrips can attack your lucky bamboo and cause foliage distortion. You’ll notice pale spots on your plant, and the stems and leaves might turn yellow.

Your plant might also have yellow leaves and stems because of root rot or leaf rot. Root rot is usually the result of overwatering or poor-draining soil if you’re growing the plant in a soil-filled container or your garden.

Leaf rot happens when you keep the leaves wet for too long. The moist conditions create the perfect environment for pathogens, and you’ll notice that your lucky bamboo is suffering, and its stalks and leaves are becoming yellow. If you have an infected bamboo, the infection can travel to nearby plants.

Easy Solutions to Cure Yellowing Leaves Of Lucky Bamboo

– Adjust Watering Routine

So, how to revive bamboo leaves turning yellow? The first thing to do is to make sure that your plant is receiving enough water. Over or underwatering can lead to the yellowing of the bamboo plant. The lack of adequate watering when growing bamboo in soil-filled containers can be adjusted by watering the plant twice or thrice a week.

You can test that the soil is moist using a moisture thermometer or touching the first inch of the soil and watering the plant if it’s dry. However, you shouldn’t use poor-draining soil because the waterlogged soil can lead to root rot that might eventually kill your plant.

If you feel your plant is overwatered, wait more between waterings. You shouldn’t water lucky bamboo according to a schedule, but always test the soil to see if they need extra water.

For the plants you keep in water-filled vases, you should add more water every 2 to 7 days, depending on the weather. You should ensure that the water covers all the roots but not the stems, as they can become soft and mushy.

Changing all the old water every 2 to 3 months is crucial. The old water creates an excellent environment that supports bacteria and fungi growth, which can later damage and kill your plants. This is also part of the feng shui principles associated with this plant.

– Avoid Using Municipal Water

Bamboo is quite sensitive to the chemicals found in tap water. So, you should avoid using it to water your plants. These chemicals accumulate in the plant’s stalks and leaves, and you’ll see your plant yellowing. The constant exposure to these chemicals will eventually kill this gorgeous plant.

Using bottled, distilled, or rainwater to water your plant is best. These types of water don’t contain harmful chemicals and will promote healthy growth. If you must use municipal water, you should let it sit for at least 24 hours before watering your bamboo. This period is enough for these chemicals to evaporate.

– Protect Plant From Intense Sunlight

In its natural habitat, bamboo grows under the canopy of taller trees and plants in the rainforest. This is why you should give it access to bright, filtered sunlight.

If you’re growing your bamboo on the patio or around the pool, you should plant a taller shrub or tree to protect it from the harsh sunlight. You can also move a plant’s container away from an exposed window to preserve this plant from getting burned.

As a matter of fact, lucky bamboo is more tolerant of shady conditions. You should cover the window with a curtain or keep the plant away from strong light sources.

– Shelter Plant From Environmental Stress

If you live in a climate where temperatures drop below 65 degrees Fahrenheit and rise above 90 degrees Fahrenheit, you should keep this plant indoors. Scorching and cold temperatures cause the yellowing of the plant, and the continuous heat stress will eventually kill it.

– Feed When Necessary

In most cases, you don’t have to fertilize bamboo regularly. This plant can survive in less-than-perfect conditions and doesn’t need to be fertilized, except if you’re growing it in poor soil. If you’re growing this plant in a water-filled vase, you might need to use a drop of bamboo-specific fertilizer to stop the bamboo plant turning brown and yellow.

These fertilizers are better suited for bamboo and contain the essential nutrients that help them grow. However, you should avoid overfertilizing the plants because accumulating the extra nutrients will harm them.

– Deal With Pests and Diseases

Bamboo isn’t susceptible to pests and diseases unless it’s heavily neglected. You can save the plant if you deal with these infections as soon as you notice the symptoms.

First, you should remove the infected lucky bamboo foliage in case of a heavy infestation to protect the nearby plants from getting infected. You can treat thrips by applying insecticidal soap, horticultural oil, and other contact sprays that quickly kill these bugs.

You can also hose the plant to remove these bugs. Moreover, you should apply insecticidal soap regularly and introduce the aphids’ natural predators to your garden, like ladybugs.

Root rot can be controlled by adjusting the watering schedule. If you grow this plant in soil, change the soil and move the plant to a new container with well-draining soil. Leaf spots can be treated by reducing shade and providing the plant with some bright indirect sunlight. You should also avoid overfertilizing the plant.
