zone 6 screen
We want to have a pretty dense screen that will grow to 20 feet or so (in
our climate, not just theoretically in the tropics). We will improve the soil with plenty of peat moss and composted cow manure, so nutrients and drainage should not be problems. We are in zone 6, and soil runs somewhat acid. The site is 125' by 6' and will have rhizome barrier. Lighting varies from part-shade to full sun. Given the fairly large area, I would like something that spreads quickly. Ideally, I like large leaves and leaves as far down the culm as possible (but a dense screen is the most important characteristic). We are considering: P rubromarginata P bissetti Pseudosasa Japonica I like the larger leaves of the P Japonica, but I am concerned that 12' might be the max in this area. I have considered dividing my 6' depth with rhizome barrier and planting a taller bamboo in the back and pseudosasa japonica in the foreground. Will having only three feet of depth limit the height on these? I had about settled on rubromarginata when a nursery person told me that its adequacy as a screen varies a lot by season and site. In Winter, it tends to be a much lighter screen, while warm Summers (especially with plenty of water) really make it dense. I was really hoping for something that would be dense year-round. Do you have any other suggestions for my situation? Thanks for your input. ----------- Bob Peticolas |

Hello Bob A dense screen and max. height is somewhat conflicting. a) Most high Phyllos. tend to have no leaves at the bottom if they are grown up (some years later). Maybe Ph.nigra henonis ist one of the best in this sense. b) If you want to have many leaves at the bottom then cut old culms early, say after 4 years instead of 5. Old culms bear most of the leaves and shade the bottom. P bissetti Is told to be very dense even at the bottom. Ask me some years later when mine is grown up :-) I had about settled on rubromarginata when a nursery person told me that its adequacy as a screen varies a lot by season and site. In Winter, it tends to be a much lighter screen, while warm Summers (especially with plenty of water) really make it dense. This is more or less typical for all Phyllostachys. I've seen 8 species in summer and early winter. I like the larger leaves of the P Japonica, but I am concerned that 12' might be the max in this area. An old grove nearby has about 5m in wine climate (zone 7). Will having only three feet of depth limit the height on these? I don't think so if the barrier is sufficiently long, especially for the smaller ones like bissetii. Maybe watering is not as good. Do you have any other suggestions for my situation? Take a look at Ph.aureosulcata and Ph.nigra henonis/boryana. The first is a strong runner and hard, a bit higher than bissetii, the second a high bamboo but maybe not a strong runner in your climate. But check if they do it in your climate! Maybe Ph. nuda is a choice, too. Another choice may be Fargesia in front of a large Phyllo. Grown up fargesia have no leaves at the bottom but so many culms that it is quite dense. Sorry for my english, I am not a native speaker. Stefan |

P. aureosulcata is nice and is a fast grower. I wouldn't divide the barrier myself I would just selectively prune to keep the lower plants in the foreground. IMO bamboo landscaping is not for the plant and forget set. |

The only reason I thought of dividing the barrier is that I am concerned that the more dominant bamboo will crowd out the less dominant bamboo, and after a few years, I will have one variety. I do a lot of gardening but I have no bamboo experience, so I could be entirely wrong about my concern. ------- Bob |

I am looking more seriously at P aureosulcata. There is a large grove nearby that looks great I understand it is known for good winter foliage. ----------- Bob |

Will having only three feet of depth limit the height on these? Do you have any other suggestions for my situation? Three feet is plenty. Have you considered P. Aurea? It grows in a dense hedge from 15-25' in height, it is evergreen and it is cheap. It is about as cold hardy as P. Bissetti (per the documentation.. I've never tested either of them for cold hardiness). How cold does it get in your area?? Golden bamboo is more golden due to its utilitarian nature... not so much the color. It takes intense sunlight to turn it yellow. As for soil amendments.. I'd avoid peat, there was some discussion a while back that peat somehow stunts shooting. Most bamboo are "bottom feeders" and will thrive in most types of soil and just about any type of fertilizer. Acidic soil is a plus. In the beginning use some time release lawn fertilizers and then once established you can move on to other fertilizers like manure. I've used Ammonium Sulfate with no ill effects on the boo, it did however kill the grass in between.. within minutes :-) Good luck! Chris So Cal |

I've used Ammonium Sulfate with no ill effects on the boo, it did however kill the grass in between.. within minutes :-) Thanks Chris. We theoretically get to -10. Last winter was by far the coldest I've experienced and we got to -2. In the 6 years before that, we never recorded a temp lower than +5. I think golden bamboo would survive here, but it would lose its leaves every winter (loses leaves between +5 and +10), and in some winters would die back to the ground. Bissetti does not lose all its leaves until you get below -5 (per EndangeredSpeices.com anyway). Thanks for the comment about peat moss. I was unaware that was a problem. I thought about using it because I knew bamboos liked adequate drainage. Soil here is pretty good anyway. ------------- Bob |

I do a lot of gardening but I have no bamboo experience, so I could be entirely wrong about my concern. Both runners are dominant, they will mix up. It is your choice to cut new shoots of one variety if you can distinguisch them. Or you separate them by a 30cm deep trench, fill in straw and cut the running over rhizomes with a knob cutter during summer. So you can keep them separated. As of Ph.aureosulcata: This is a very upright bamboo and keeps upright in comparingly strong winds. The culms of the aureocaulis (yellow) or spectabilis (yellow with green sulcus) type are a nice contrast to the green leaves. Stefan |

Hi Chris P.aurea doesn't do very well here (zone 7), it survives (depends on which subspecies you have choosen) but has damages every winter, may even freeze down while P.bissetii is one of the best in our climate. The reason may be that we often have cold winter nights (-10, sometines -15 Celsius) without snow combined with dry continental winds and sunny, warm winter days. This is more hassling to bamboo than -20 Celsius WITH snow. So don't rely on the temperature alone, there are some other important points to watch. Stefan |
