In general, bamboo is considered a fast-growing, robust and undemanding plant for indoors and outdoors - provided you know its needs and give it the right care. Why does bamboo turn its leaves yellow in autumn, even though it is an evergreen plant?
Why does my bamboo have yellow leaves?
Yellow leaves on bamboo can be a natural phenomenon in autumn, but in spring or summer they can indicate waterlogging or a lack of nutrients (chlorosis). To solve the problem, better drainage or targeted fertilizer application is necessary.
Depending on the type of bamboo, the yellowing and the later, partial leaf fall in autumn varies. However, you shouldn't worry about it. Your bamboo does not get sick or suffer from any deficiency. He is simply preparing for the coming cold time in winter. To do this, he frees himself from part of his leaves. As soon as the first autumn storm blows away the yellow leaves, it shines fresh green again. Don't worry, just enjoy the autumnal golden yellow leaves.
Causes of yellow leaves in spring and summer
You should take a closer look at bamboo plants when the leaves turn yellow in spring or summer. Two bad causes that can be responsible for this:
Waterlogging causes the leaves to turn yellow
If there is too much waterlogging, the roots rot and the leaves turn yellow. Now, as with brown leaves on bamboo, you have to act immediately. Remove the plant from the container or soil. The soil needs loosening and drainage. Raised hill planting can sometimes quickly provide relief. When using bamboo in a pot or as a container plant, check the openings for water drainage and clean them if they are blocked.
Yellow leaves as a result of chlorosis
Acute nutrient deficiencies such as too little iron, magnesium, nitrogen or soil salinization can result in chlorosis. A targeted application of fertilizer (€8.00 on Amazon) and replacing the bamboo soil helps here.
Yellow leaves on indoor bamboo
Yellow leaves on indoor bamboo also indicate too much moisture. If the irrigation water does not drain, the roots in the flower pot will rot. It's best to unpot the plant and check the roots for dark, rotten spots. If there are any, cut them off with a clean knife down to the he althy, light roots.
Then plant the bamboo with fresh soil or humus. A partially shaded sunny spot supports the regeneration of the plant. New shoots and fresh green leaves will sprout in the next growth period in spring at the latest.
If you want to do something good for your bamboo plants[/], give them a shower every now and then or spray them. Because the bamboo absorbs a lot of moisture through its leaves. A shower also removes dust and bugs. Make sure that the undersides of the leaves are also showered sufficiently.
Tips & Tricks
Do not fertilize newly purchased bamboo plants until after one year. As a rule, the plants have been pre-fertilized and have been supplied with all the important nutrients by the breeder.
