Phyllostachys glauca
bamboo
- Position: full sun or partial shade
- Soil: humus-rich, moist, well-drained soil
- Rate of growth: average
- Leaves: dark green
- Canes: blue-green
- Hardiness: fully hardy
- Garden care: Plant in a large container or surround the roots with a non-perishable barrier that restricts the plant's spread. If potted up, it is important that this plant is watered regularly.
A rare clump-forming, then spreading bamboo. The new canes are an attractive shade of greenish-blue and look like they have been dusted with white powder. Later they lose the blue flush and become greener as they canes mature.The leaves are glossy and dark green though glaucous underneath. A superb specimen plant, it looks great in a contemporary, minimalist garden or a town garden. To prevent the plant from colonising adjacent plantings restrict the roots using a rigid, non-perishable barrier.

Can I grow a Bamboo in a pot?
Dear Sir Please can you tell me if I can grow a bamboo in a 2ft deep window type box for a patio? Thanks RogerAsked on 4/15/2010 by roger pannell1 answer
A:
Hello Roger, As long as you make sure you keep it really well fed and watered, it should be fine as long as it is nice and wide. After a couple of years though it will need to be planted in the ground - as will most things that grow to a good size. I hope this helps. Helen Plant DoctorAnswered on 4/16/2010 by Crocus Helpdesk
Q:
Can I plant my Bamboo in the ground in a pot with drainage holes?
I have a couple of largish bamboos that I wish to plant in a pot in the ground. However, the plastic pots have drainage holes in the bottom. I know that bamboo can become extremely invasive (which is why I wish to plant them in pots). Will the roots go through the holes in the bottom? Or should I use pots without drainage holes? If so, will the bamboo survive with no drainage? Or is there a special type of pot for this purpose? Many thanks. AnneAsked on 4/6/2010 by Anne Lear3 answers
A:
Hello again Anne, The Phyllostachys nigra is classified as non-invasive (or clump-forming), but even so it has an eventual spread of 3m. I hope this helps. Helen Plant DoctorAnswered on 4/12/2010 by Crocus HelpdeskA:
Can certain types of bamboo be non-invasive? I have, apparently, a black bamboo. Many thanks AnneAnswered on 4/12/2010 by Anne LearA:
Hello Anne, The bamboos will not survive without drainage holes in the bottom of the pots, so this is essential. Sadly though even a tough plastic will deteriorate over time and may crack and split, so they will certainly help, but in the very long term the plants may break out. I hope this helps.

Q:
Bamboo planting and controlling
Hi I recently purchased six of these bamboo plants and am not sure how to plant them. Do they need to be in individual containers to avoid spreading? And how big should the containers be? I don't want to restrict the growth too much as I'm aiming for a screening effect in a corner of the garden at the back of a border, where a bit of spreading would be ok. Also might I be able to prune the spreading manually as the shoots appear? When it is suggested that the plants should be controlled with a 'non-perishable' barrier - what is that? Many thanksAsked on 10/29/2009 by harriet st johnston1 answer
A:
Hello, If you go for one of the spreading rather than clump-forming bamboos then you will either need to get a really a big plastic pot (at least a 50 litre pot) or a plastic dustbin with drainage holes in the bottom and sink this into the ground. Alternatively you need to create a barrier that won't break down like a thick wall of concrete and sink
this at least 3' into the ground around the area you want them to spread. Unfortunately we don't sell either of these items, however they should be relatively easy to find. You can cut off the emerging stems that are growing in the wrong area, but this will not prevent the roots spreading and therefore the shoots will come up in a wider radius each year. I hope this helps. Helen Plant DoctorAnswered on 11/2/2009 by harriet st johnston
Q:
Bamboo for screening but how do I restrict it.....
Hi I would like to create a bamboo screen along a fence roughly 25feet in length. I would like to use bamboos and have them blend into each other and be reasonably thick. Will I need a plastic barrier to reduce the spread or can this be maintained by removing any shoots that appear? Roughly how far will I need to space the plants? Do bamboo roots cause damage to house footings? Thank you MattAsked on 10/26/2009 by Matt Oliver3 answers
A:
Hello again Matt, We do have the eventual height and spread of all the plants on our site - these details can be found to the right of the pictures after you have clicked through to the individual plant cards. Phyllostachys aureosulcata f. spectabilis 3m tall x 6m wide Phyllostachys nigra 5m tall x 3m wide. As for the barrier, ideally it will need to be around 1m deep and really solid. Best regards, Helen Plant DoctorAnswered on 10/26/2009 by Crocus HelpdeskA:
Thanks Helen What is the spread of Phyllostachys aureosulcata f. spectabilis and Phyllostachys nigra? Does a barrier have to go below the roots or just either side? MattAnswered on 10/26/2009 by Crocus HelpdeskA:
Hello Matt, Some bamboos can cause damage to the footings, but it really depends on how vigorous the plant is and how secure the footings are. The most compact (in spread) bamboo we sell is Fargesia murieliae, which has an eventual spread of 1.5m - just click on the following link to take you straight to it.
http://www.crocus.co.uk/plants/_/bamboo/exotics/fargesia-murieliae-/classid.1583/
It will take time to grow to this, but if you want to restrict it, then you do need to make sure the roots can't spread and that will mean putting in some form of barrier. As for spacing, most people will plant these at 50cm intervals if you are trying to create a nice, dense
screen. I hope this helps. Helen Plant DoctorAnswered on 10/26/2009 by Matt Oliver
Q:
Can I plant a Bamboo by a large conifer?
Hi, I am thinking of planting a bamboo plant to use as a screen to maintain privacy. It needs to be tall and compact. Where I wish to place it, is alongside a conifer which is approx. 18/20 feet high. I eventually want to get rid of this conifer as it's dying off. If I were to get rid of it now, it would open up an area and hence we would be overlooked. I thought I would plant a bamboo and allow it to get established, before I got rid of the conifer. Any thoughts would be welcomed. The bamboo I have in mind is the Phyllostachys vivax f. aureocaulis. Awaiting your response PatAsked on 10/24/2009 by Pat Jones1 answer
A:
Hello Pat, I'm afraid it is going to be incredibly difficult to get anything to grow in the dry, shady conditions next to your existing conifer. Bamboos in particular like quite a lot of water, so won't cope with the competition for water, light and nutrients. I'm afraid then your best option would be to bite the bullet and get rid of the conifer and then invest in a more mature plant to replace it. I'm sorry not to be more help.

Q:
Are Bamboos ok for a windy roof garden
I notice you have some Bamboo plants in your sale. I heard some time ago that one species of this plant was one of the fastest growing. My excitement was dampened when I also heard that it was not wind tolerant. I have a roof garden in London that is exposed to the full force of the wind and am looking for fast growing plants that I can place all around the perimeter to act as a wind break. They must, of course, thrive in the wind. Have you any ideas and are any of the bamboo plants in your sale, suitable for this purpose? Many thanks.Asked on 8/17/2009 by Alan Coulter1 answer
A:
Hello There, Bamboos make up a huge group, but as a general rule the fastest growing ones are not suitable for pots and I'm afraid we do not sell any that are happy in very exposed positions, which is a very tricky situation for plants. I think ideally you should try to create a windbreak from some form of screening which will then offer some form of shelter to the plants. I'm sorry not to be more help.

Hello There, You can give them a light trim, but these plants do not really need it, and will prefer it if it kept to a minimum. I hope this helps. Helen Plant DoctorAnswered on 8/18/2009 by Crocus Helpdesk
Q:
Container Bamboos for a terrace
Hello - I'm looking to create planted screens for two sides of south-east facing terrace and I was hoping that hardy bamboos might be a good-looking and robust solution. Visually I was thinking of alternative plantings of golden grove and black bamboos (5 ltrs) in long troughs, to be set against the wooden railings. Is this a workable idea - and if so how much room should I allow between plantings and what's the best soil for this purpose? Do you think the plants will have to be protected against frost for the first winter and if so, what would you use for this? Thanks for your help, LeeAsked on 7/13/2009 by Lee Robinson1 answer
A:
Hello Lee, Bamboos are quite thirsty plants so need to be kept really well watered when they are grown in pots. They also resent very windy or exposed sites, however if you feel it is reasonably sheltered spot and you can either install an automatic watering system or make sure they get loads of water, then these make great screening plants. You should get the largest pots you can find, fill these will John Innes No2 or No3 and plant them at 50cm intervals. They are hardy plants so will not need winter protection.Answered on 7/14/2009 by Crocus Helpdesk
Q:
What can I feed my Bamboo with?
I would be grateful for a suggestion of a product to feed some Phyllostachys aureocaulis and nigra as I believe high nitrogen feed (i.e.Miracle Grow) is not suitable. Many thanks SusanAsked on 6/29/2009 by Sue Greene1 answer
A:
Hello Susan, Miracle-Gro is perfect for feeding Bamboos as it is a balanced, general fertiliser rather than one that is particularly high in nitrogen.Answered on 7/4/2009 by Crocus Helpdesk
