Bamboo Doesn't Shoot

dkjensenJune 10, 2014

I have a larger timber bamboo that I harvested from an abandoned home 10 years ago. It has been in the ground now for 4+ years. It seems to only shoot every other year. All signs are that it is healthy (new growth up top but I have not done any digging). The year after I moved it from pot to ground it sent up one good size shoot, probably 1.25 inch. Then nothing the next year. Last year in May I got two shoots, both the same size as previous. This year I haven't seen anything. Is it a normal thing for a bamboo to shoot bi yearly? Should I be concerned about anything? Thanks for the help and insight.

I wouldn't be concerned if it looks healthy otherwise. I have many bamboo; most, but not all, shoot annually.

A fully stimulated bamboo triples in size every year. Something is preventing yours from getting up a full head of steam. Is it mulched? If you put on a thick mulch, so that soil moisture conditions are tempered you may say a huge improvement in culm size and number.

Hello, dkjensen...what hardiness zone are you in?

I am not sure the exact zone we would be in. We are just outside of Seattle. Minimum temperature of about 15-20 but not every year does it get that low. Common to get a little below freezing in the winter. I have not mulched the bamboo. I have fertalized twice a year with an organic lawn fertalizer. I have a smaller black bamboo that I have treated the same way and it seems to be thriving.

I'm in the Seattle suburbs and so your Zone is likely the same as mine: 8B. Winters here do not harm the growth of timber least in my experience of over 10 years growing bamboo. I can't say for sure why yours doesn't shoot every year, but it doesn't mean there is something wrong with it. Also, I am less optimistic than bboy about growth. I have about 60 species of bamboo under cultivation, and they certainly do not triple in size every year, even though they are well taken care of.

I guess I will try and not worry to much about it. This is my first experience with timber bamboo. It might help if I knew what kind it was as well. I will make an effort to mulch it this year. I have not done that yet. Thanks for the input!
