I'm in the PNW also. You may not get any more shoots this year, as shooting usually occurs in a short period of time in our area. Also, it typically takes at least 3 years for a bamboo to get established in the ground before you get vigorous shooting. Finally, different species have different characteristics. I moved to my current house a little over 3 years ago and put a lot of bamboo in the ground at that time. Some of it threw up new growth rather quickly and some has been slower to get established.

(P.S.: The stalks are called "culms," not "clumbs.")

Thanks for the info knudzo9. How long is the shooting period from your experance? I was really hopingmy bisetia would take off this year. This should be the leeping year... or so the saying goes..

Thanks Doug

PS are you seeing a lot of shooting now?

It really varies. I've got about 60 species, and some started poking up a couple of weeks ago, but most have yet to start. My Bissetii has been in the ground at least two years and I've just gotten a couple of whip shoots from a mature division. My Vivax aureocaulis send up a lot of large shoots in about a one-week period one year after it went in the ground, but last year it hardly did anything, and has done nothing this year. I have other species that have been very aggressive shooters -- like Robert Young, Castillon, and Arrow -- almost from the beginning. Most of my bamboo will be done shooting in June. All I can say is be patient. This year or next you should be happier about this situation.
