Yellowing Leaves on Oldhamii Bamboo

melwins10(9-10)March 6, 2012

I have planted 15 gallon Oldhamii timber bamboo all around my property and the leaves on most of the plants have started turning yellow this past week as well as the stems. I withdrew watering and then the leaves started to curl lengthwise, so I watered again. I am at a loss as to what to do. How many leaves die back in the spring? Could this be it?

Where did you get the plants? Were they in pots from a nursery (and supposedly stabilized), or were they recent divisions you got from someone? In your Zone healthy Oldhamii should not be losing many, if any, leaves; it sounds like possible transplant shock. Bamboo culms can completely defoliate and still recover, but if the culms/branches turn tan, it means that those particular culms are not going to recover. It is hard to over-water bamboo unless you leave them with standing water for days/weeks; leaf curling is a signal that more watering is needed.

How were the plants transported to your property? Did you fertilize them at the time of transplanting?

Can you post some pictures?

Thank you so much for answering. These Oldham's were bought two months ago from a local nursery in Gardena, CA. near where I live, zone 9 "ish." I ammended the soil with lots of compost -- Kellogg gardening soil, however, the soil deeper down is clay. We've had a few days of heavy rain, then wind, then cold snaps around 40 degrees at night. The "boos" were fine until this and the leaves seemed to yellow within a few days. I'm checking the soil, it seems moist but not waterlogged. I'm using a grass slow-release ferilizer high in nitrogen.

It could very well be transplant shock. If you will notice, the dying leaves start back at the stem, not from the ends of the leaves, (cold nips from the ends of the leaves). Your plant is drawing something from the soil that is doing this.
Is there any chance that there could be some weed killer in the soil where it is planted? Or run-off from an area where weed killer or chlorine bleach could contaminate the soil? I know bamboo is very sensitive to chlorine, which it can come in contact with from a laundry drainage area. These are just ideas of thought, stabbing in the dark as it were!

My bamboo is about three years old. the leaves aren't browning like in the photo above - but they are all yellowish - as opposed to a healthy green.
