Your bamboo suddenly got yellow leaves and doesn’t look nice anymore?

This can have various causes, and these should be resolved as quickly as possible. We’ll show you the most common reasons for yellowing bamboo leaves and also some ways you can get your plant healthy again.

1. Waterlogging In Bamboo

There is one thing that bamboo doesn’t like at all – namely waterlogging. This is arguably the most common cause of yellow leaves. If the roots of the plant are in the water for too long, they will rot, and your bamboo will get yellow dead leaves.

If you have poured too much, quick action is now essential.

The first thing to do is to remove the plant from the old soil to dry out the roots a little. Then the too-wet and dense soil must be replaced. Before attempting the next planting, use drainage so that excess water can drain away easily. The soil should be nice and loose, rich in humus and sandy. Under no circumstances should the soil used be loamy.

The drain in the bucket must then always be checked regularly so that it does not get clogged, and water can collect in the first place. If your bamboo is planted in the garden, a slightly hilly planting can help. This allows accumulated water to drain off better.

2. Yellow Leaves From Chlorosis

Another cause of yellow leaves on outdoor bamboo can be chlorosis. This term describes a disease symptom in plants that can be triggered by a lack of nutrients. As a result, there is a chlorophyll deficiency, which leads to yellow instead of green leaves. The affected plant is often lacking essential nutrients such as nitrogen, iron, magnesium, or calcium.

Chlorosis usually only occurs in young leaves and then spreads to the entire plant. If you don’t take action now, the bamboo can die. So don’t hesitate and provide the bamboo with sufficient special fertilizers.

Chlorosis can also be triggered by saline or calcified soil. It is best to report the bamboo into special bamboo soil. In winter, however, you should fertilize your plant; it is in a kind of hibernation.

3. Yellow Leaves Due To Drought

Yellow, dry leaves with brown tips indicate drought damage in bamboo. However, this happens very rarely. This can happen, especially in winter, when the entire soil and roots are frozen. Since bamboo is an evergreen plant, water also evaporates from the other leaves in winter.

If there is no frost for a long time, the plant can no longer supply itself sufficiently with liquid water, and the stalks die off. To prevent this, you should water your bamboo regularly, even in winter. But with much smaller quantities than in summer. Just in such a way that the earth remains slightly moist.

4. Pests On The Bamboo

Unfortunately, bamboo is not entirely immune to mites, fungi, and other pests and can certainly catch a disease. As a result, yellow and brown spots can appear on the leaves, or they die off completely.

Disease from pests and how you can cope with them:

  • Mealybugs can attack the bamboo plant and cause deformed leaves. These are often located on the branches of the bamboo stalks. In this case, the lice must be brushed off, and diseased parts of the plant removed. If the lice come back, a mixture of pure alcohol and water can help kill the lice.
  • Aphids usually attack bamboo from spring onwards. If there are sticky spots on the leaves, you have to reach for the aphid killer and treat the plant accordingly.
  • So-called grain rust fungi can attack the bamboo and cause brown-red spots. Collect the affected leaves and observe the further course. If the damage recurs, appropriate fungicides are available to deal with the situation. But please pay attention to environmentally friendly preparations.
  • Bamboo mites can also infect your beloved plants. This type of mite is often introduced when it is imported from China. The small brown spots on the upper side of the leaves are striking in the damage pattern. At the bottom, you will find the webs of the mites. The only remedy here can be pesticides or special predatory mites.
