|3 monrovia clumping beechy bamboo planted in ground 3 yrs ago. Leaves are yellow-gold and falling. Fertilizer did not remedy. Prolem? Also, how often/how much should be thinned .|
|It is normal for some of the leaves on bamboo to turn yellow and drop. This occurs throughout the year, but it is particularly noticeable in the spring. The dropped leaves will be replaced with new leaves. Other causes of yellowing leaves are stress, drought, excess water and lack of nutrients.
You can thin by removing the oldest, least producting culms on an annual basis. Bamboo is really just a giant grass - when you cut it back, it responds with lots of new growth. Best wishes with your garden!
