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.

I planted golden bamboo last winter and in the spring it was looking good and sending up new shoots. Now it has really bushed out and again new shoots coming up BUT now it has started to turn yellow. At first it was just old leaves; now it is new ones also. It is very hot here. I have been giving it organic fertilizer and recently put old manure and some compost on the soil. The soil it is in is soil that drains well. I don't know if it is coincidence but the leaves started to turn yellow more after I put the manure around the plants. However, this is when the really hot weather arrived too. Please can you give me some advice? I have been watering it every day and just yesterday gave it more fertilizer and a good soaking.
You should not try to fertilize during hot weather as this can lead to root burning, which results in the yellowing you are seeing. I would try to flush out some of the excess fertilizer by hosing down the area for about 10-15 minutes or so.
Do you know what thickness metal would be appropriate to contain bamboo?
Since many times bamboo is grown in wood whiskey barrels, I would not think that the thickness or gauge of metal needs to be to thick.
Do make sure that you have appropriate drainage no matter the container you choose.
My husband thought he was doing me a favor by trimming the base of the bamboo. He went a bit too far and chopped the tops off of every cluster and removed every leaf off each of the plants. They are in a love cluster outside, but have been reduced to sticks. Is there any chance they will survive? The grove has been there for 5-7 years and used to stand 12-15 feet tall.
Normally with bamboo, you do not prune, you dig. Bamboo spreads quickly and to maintain a contained space, anything that is outside the space is dug up.
Don't worry, bamboo plants are hard to hurt. You can prune bamboo quite freely to reshape it or to rejuvenate it. It really is a plant that can take almost any abuse. Just trim away any parts that are looking a bit ragged. It will grow back more lush and full.
Do you have a product that I can buy to kill bamboo? Is it possible to eliminate all bamboo rapidly? We have a lot of problems to kill them. My husband and I have tried to eliminate them without success. Thank you for your suggestion of products.
Here is an article that will guide you in controlling the spread of the bamboo:

Happy gardening!
The stalk, up to 4 ft, is covered with black spots that get denser and slowly cover most of the surface. Does anybody recognize what is causing this problem and how to address it? The leaves above look green an healthy. Please, email me if you have any information. Thank you. Antoaneta
Thank you very much! We will try the fungus treatment.
This looks like a fungus issue and may even be the results of root rot.
There is treatment for most fungus issues but root rot can be devastating to the plants.

Can I plant a bamboo in a half barrel? I need to screen a small area.
