arrow bamboo 'japonica'
- Position: full sun or partial shade
- Soil: humus-rich, moist, well-drained soil
- Rate of growth: fast growing
- Leaves: dark green, oblong
- Canes: olive green, maturing to pale beige and dark green
- Hardiness: fully hardy
Tall, vigorous bamboo with olive canes maturing to pale beige and dark green oblong leaves. Arrow bamboo is one of the most wind and shade tolerant varieties. Broadly upright in habit, as long as the roots are surrounded with a non-perishable barrier it makes an attractive screen or windbreak for moist, well-drained areas of the garden.
- Garden care: Plant in a large container or surround the roots with a non-perishable barrier that restricts the plant's spread

Q: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 pannell
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 Lear
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 Helpdesk
A:Can certain types of bamboo be non-invasive? I have, apparently, a black bamboo. Many thanks AnneAnswered on 4/12/2010 by Anne Lear
A: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:Pseudosasa japonica - Arrow Bamboo
Hi, Please could you advise on the height of Pseudosasa japonica bamboo when delivered, and also what size pot should it be planted in for vigorous growth? Many thanks MoiraAsked on 1/11/2010 by Moira Turner
A:Hello Moira, These plants will be around 30-40cm tall in a 3lt pot. As for pot size, the bigger the better really as they have an eventual spread of around 8m, so will need space to grow and it will be crucial that you make sure they are kept really well fed and watered. I hope this helps. Helen Plant DoctorAnswered on 1/11/2010 by Crocus Helpdesk
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 johnston
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 canes in a pot?
Morning Roughly how many Bamboo canes are there in a 5ltr pot? ThanksAsked on 8/18/2009 by Sean Williams
A:Hello, As a very general guide, I would expect between 1 and 3 canes per pot. Best regards, Helen Plant DoctorAnswered on 8/19/2009 by Crocus Helpdesk
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 Coulter
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.

I have planted Bamboos up against a brick wall 10ft. high.They are now just reaching that height- can I trim the tops to stop growth? Regards DaveAsked on 8/17/2009 by david smith
A: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 Robinson
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
