Growing season?
Hi,
We planted a reasonably mature 7-8 foot high bamboo tree(?) around October last year, but it has not visibly grown yet. Should I expect that? Is the growing season just about to start, as we enter spring? I'm in England. The bamboo was the common type, and green. I can find the exact name if that is important! Neil |

Growing season?
Hi Neil,
This is normal, but you should be rewarded for your patience soon. I would be happy to give you more specific details if you tell us the variety. But the following things are true of all bamboo: Bamboo "shoots" for only a couple of months per year around May. Each bamboo shoot comes out of the earth and reaches it's full and permanent height in 6 to 8 weeks. So the culms (the stalks) that you see today will never get any bigger. However, you can expect new culms to "shoot" up in the near future. New culms are typically bigger than old ones (once grown). This is how the plant increases size and height... It uses the energy gathered from several smaller culms to produce a few bigger ones each year. Sometimes the shoots will just poke out of the ground a little and appear dormant for a few weeks before they actually start their quick growth spurt. And if some of these emerge that never grow, don't worry. I have seen a lot of cases where several shoots emerge, but only half of them actually grow. This can happen to all plants, but is particularly common with new divisions, as the plant might have several buds ready underground, but when the plant was cut in half for division, it no longer has enough energy to make them all grow. Let us know how it goes in May. Cheers! Neil wrote: Hi, We planted a reasonably mature 7-8 foot high bamboo tree(?) around October last year, but it has not visibly grown yet. Should I expect that?

All the stalks I have now, grow no more, but instead new shoots will come out during May, and grow higher than the original/existing ones? ps. what I have is a "Phyllostachys Aureosulcata" or short name "Aureocaulis".

That's right. Though once established, it can really increase in size
(by putting up new shoots) each May. Once it gets going, you can feel free to get agressive about pruning out the smaller culms or culms that are too close together, and trimming off lower branches to show off the culms that they might be obscuring. If you want to give it as much energy as possible for growth, do this in late fall / early winter. If it is growing too quickly and you want to slow it down, do this right after the shooting season finishes. FYI, you probably have Phyllostachys aureosulcata 'Aureocaulis', which is a little different (golden vs. dark green) than regular Phyllostachys aureosulcata. More info on this bamboo (both types) can be found at these links. I have no affiliation with the site, but find it has good info. http://bamboogarden.com/Phyllostachys%20aureosulcata%20'Aureocaulis'.htm http://bamboogarden.com/Phyllostachy...eosulcata.html Cheers! |

The culms (stems) you have now will not increase in size.
New culms will emerge in the spring but will likely be smaller than the existing ones. After about 7 years you will see the biggest ones emerge. It takes a lot of energy to make new culms and right now most of the energy is going into just stabilizing this new planting. |
