Q.bamboo is looking unhealthy
Our bamboo is looking unhealthy. We have taken to nursery but they are stumped – think it’s a mite but we cannot see the mite. Leaves have a stain in spots and look like they have yellow spots and drop off.
In the spring yellowing leaves and dropping leaves is natural for bamboo.
Some species do this more than others.
Bamboos are evergreens and naturally renew their leaves in the spring. It is not unusual to see a bamboo with green leaves, yellowing leaves and newly opening leaves.
The yellow leaves will just gradually fall.
Now if you are seeing other signs of insects, damage in leaves, you may need to treat the plant with something like Neem OIl.
Neem Oil works as both a pesticide and fungicide.
