how to tell too much shade ?

Posted by elvie z9CA (My Page) on

Hello. I have Phyllostachys aureosulcata and Borinda Boliana in 24" pots. The area is 1/2 day sun from March to August, then decreasing , and is now it is in full shade until next March.
So far, they still look good, but I am noticing more yellowing leaves, even on the still young Borinda Boliana. Is that the first symptom of not enough sun?

is there any bamboo that can take full winter shade?

Himalayacalamus porcatus likes shade. Rgds

RE: how to tell too much shade ?

The yellowing leaves could be a function of not enough sun, or may just be seasonal leaf change/drop. In any case, it shouldn't be fatal to the plants as bamboo can usually tolerate a range of sun/shade.

One that I know that likes shade, though, is Pseudosasa japonica.

RE: how to tell too much shade ?

Thanks, I moved the Borinda and think I'd better move the Yellow Grove as well.

I have a Pseudosasa japonica that actually I did buy for this very spot in the first place, but since it was just a 1 gallon, I have it in part sun, figuring it will grow faster than it will in full autumn /winter shade. Is the best plan to probably to let it grow in part sun until it is a large size, then move it to the winter shade area?
Whatever i put there needs to eventually tolerate summer sun as well.


RE: how to tell too much shade ?

I've grown Ps. japonica in part sun and I've also grown it in pretty much full shade under some large Douglas fir trees. But I'm in the Pacific NW and so my summer sun is much gentler than yours. If it gets full summer sun in your area (SoCal?) you should keep it well watered and be prepared to move it if it isn't happy.
