A giant bamboo species that is slow to mature but makes a beautiful walk through grove and thick privacy bamboo screen while waiting for it to size up. Known for excellent wood qualities.

Phyllostachys Bambusoides 'Giant Japanese Timber' is the mother form. It looks the same as 'Crookstem' except larger in subtropical climates and without the very slight bend of the cane on some specimens. This giant is slow to mature. In our experience, we find it best suited for climate zones 7 and 8. Only under ideal growing conditions of great soil, full sun will it reach mature sizes with thick culm (cane) walls. It does not need a cool dormant period like most other temperate species.

'Giant Japanese Timber' produces a beautiful walk through grove and thick privacy bamboo screen while waiting for it to size up.

In USDA Climate Zone 7 and 8 expect mature size canes to be over 70 feet in height.

The only large groves I have seen of the 'Giant Japanese Timber' bamboo have been in climate zones 7 and 8. Not as cold hardy as the 'Slender Crookstem'. It gets top damage here in zone 7 when temperatures drop into the low twenties. Completely defoliates at around 5 to 10 degrees F.  Canes die from 0 to -5 degrees F.

'Giant Japanese Timber' flowered during the 70's and into the early 80's. Mature groves are now hard to find and some sporadic flowering is still being reported. Some clones of this species are reported to be in flower intermittently without lost of the grove.  Our clones are not in flower and we would not sell any that was.

Plant introduction number (PI) into the U.S. 1189926

The Japanese name for Phyllostachys bambusoides is Madake and the common name for it in China is Gui zhu

How Bamboo Grows

Bamboo grows a little different than most plants. The bamboo that you get initially never grows vertically again. It has babies that are taller, that has babies that are taller. Every generation should be taller that the previous year's shoots. The intriguing aspect is that each year’s growth emerges and grows to it complete height in 60-90 days. They spread as they produce larger growth, filling in and providing a screen.

This link will help you learn how bamboo grows. It will give you an idea of what kind of growth to expect from your planting. It is a lot of information, but well worth your time. How Bamboo Grows


Planting bamboo is also easy. You want to dig a hole about twice the size of the root ball. When you plant the bamboo amend your soil with composted manure and a good top soil. Bamboo can be planted at ground level or slightly deeper. It is not a picky about it conditions but this will help get it off to a good start.

One division of bamboo will start a grove or screen over time. However, if you want a privacy screen fast, we recommend planting bamboo 3 to 5 feet apart. This will hopefully allow you to have a good screen in three years. There are a lot of factors such as water, sunlight, and climate zones that speeds up or slows down the process. Three years is about the average on this spacing, closer planting will allow you to screen or develop your grove faster. You cannot over plant bamboo.



Bamboo can benefit from a fertilization program. You can safely fertilize your bamboo once it has been in the ground for one month. A time release fertilizer will work great. Time release fertilizers allow for proper absorption in case your soil is out of PH balance. We offer some fertilizer to help with growth. We fertilize twice a year. Once in the early spring to encourage new growth and then again during the middle of the grow season to replace any nutrients that are being depleted.

Over the years a lot of myths have been told about bamboo, while it can spread under good conditions, it is not as invasive as many people would have you believe. In colder climates an aggressive runner here in the south will hardy spread at all in comparison. We have been growing bamboo since 1985 and had experience with it long before that. The bamboo's underground root system (rhizome) will spread beyond the initial planting over the years, so in the next two or three years you will need to decide on some method of containment on the sides you do not want the rhizomes to run over into.

We have constructed a page discussing multiple methods of controlling bamboo. It goes over root pruning, mowing new shoots, and in ground barriers: Controlling Bamboo

All this said and it may discourage you, but as with any plant there will be maintenance. Bamboo is very beautiful and is great in a Japanese style garden, but it will need maintenance down the road. At first it may seem to be doing nothing, but after 3 to 5 years you will have a lot of beautiful culms (canes) and love the foliage. All our 150 plus species simply contained by mowing and weed eating the new Spring and Summer shoots. Hopes this helps and don't be afraid of the bamboo.
