Most bamboo grow in temperate to warm Asia, China and Japan, but some forms occur in other regions of the world. Zone6 gardeners can expect temperatures to drop to -10 degrees Fahrenheit (-23 C.), which means some bamboo species will thrive in the zone.
Northern gardeners can harness the exotic, tropical feel of bamboo by choosing winter hardy varieties or providing a microclimate. Growing bamboo in zone6 that is less hardy may be done by containerizing plants and moving them indoors or to sheltered areas during the coldest periods of the winter.
The Freesia group are the desired clumping forms which are not as invasive as running types that colonize through vigorous, tough rhizomes. Phyllostachys are runners that can become invasive with no maintenance but can be kept in check by cutting back new shoots or planting inside a barrier.
Both have the capacity to survive temperatures below 0 degrees Fahrenheit (-18 C.), but leaf loss may occur and possibly even shoots will die back. As long as the crowns are protected by mulching or even covering during severe freezes, in most cases, even shoot death is recoverable and new growth will occur in spring.
But you should be careful to choose a cold hardy bamboo variety. There are more than a thousand species in the bamboo family, and the majority of them come from the tropics or subtropics.
Freesia is more popular among homeowners as it contains many wonderful well-behaved types of non-invasive bamboo. They are used in various landscape designs adding unique texture and a year round pop of color.
Forms a very dense screen with unusual yellow and green striped canes. A sow-spreading bamboo ideal for use in shady areas as a small shrub, hedge, or ground cover.
A bamboo with interesting stalks of purple or dark reddish color. You can also plant them a bit further apart if you have chosen a fast spreading runner and are willing to give it some time to fill out.
Most bamboo will not suffer from it BUT their growth rate may be slower than for the plants you give more space. To grow a full size bamboo grove, larger intervals are recommended (5 to 20 feet, depending on species).
In colder regions like Zone6bamboo should be planted outdoors early enough to become established before the next winter comes. If you plant later in the year like June or July, to improve the chance of surviving the first winter, provide your new bamboo with a deep layer of mulch and give it extra protection from cold and drying winds.
When filling back the planting hole with soil add well composted manure to the mix. To choose the right type of bamboo for that spot you should keep in mind how sunny or shady the chosen place is.
There are bamboos that like lots of sunlight and others that can grow well in shady areas. For example, most Phyllostachys grow best if they get at least 5 hours of direct sunlight daily.
Freesia, Thamnocalamus and NASA bamboos, on the other hand, tend to do well with light to moderate shade. Newly planted bamboos need frequent and generous watering in the first season until they get well established.
It is not good to water them every day or leave them in soggy wet soil. That can lead to problems like excessive leaf dropping and root rotting.
All species of Phyllostachys, NASA, Shibataea, Pseudos and Pleioblastus are running bamboos. They can become invasive with no maintenance but can be kept in check by cutting back new shoots and installing root barriers.
Also, correctly installed 60 mil by 30 inches deep HDPE (high density polyethylene) root barrier is very effective for rhizome control. 30 mil by 24 inches will do in many cases, however then you should be extra careful and check more regularly if it's still holding well.
For that reason you should avoid loose soil or air pockets next to the barrier just in case the bamboo goes deeper than you want. Another method for control is digging a shallow trench (8 to 10 inches deep) and check a couple of times in the summer and fall for any rhizomes that have tried to cross the trench.
Keep in mind that bamboo in containers will grow smaller than their in-ground relatives. They are more sensitive to heat and cold, strong winds can tip them over, and the restricted root space allows them to dehydrate quickly, so they need more watering.
This giant specimen timber bamboo grows quickly to 45 feet with a diameter of 5 inches. Known in the botanical world as Phyllostachys viva, it is attractive, with green stripes on its yellow canes.
Hardy to temperatures as low as minus 5 degrees F, the Green stripe bamboo also has large leaves, making it suitable for growing as a hedge. The canes are light green when they first emerge but turn gold when they receive plenty of sun.
It can tolerate full sun and achieves a mature height of 35 feet in USDA hardiness zones 6 and higher. Ambush dolichomerithalla is a fast- growing, clumping type of bamboo, reaching an adult height of 25 feet.
Silver stripe bamboo has white stripes on its leaves and sometimes on its cults, which grow to only 1 inch in diameter. Bamboo products are huge today, finding a place in the kitchen and home.
Though it does not state the exact species that grows the quickest, it is more than likely a member of the Ambush and Phyllostachys genera. Load Video To reach this quick growth, the bamboo has to be in the absolute perfect conditions.
Growing these plants to immense heights and quickly takes some work and education. This cone is very interesting as it contains all the cells that will eventually become a new bamboo stem, which is referred to as a cult.
The cell walls do not allow the plant to expand laterally, forcing them to elongate quickly. After initial growth, you will see the side stems and leaves of the bamboo plant developing.
To allow the plant to reach its full potential, all it needs essentially is the proper amount of water to fill its cells. It is considered a timber bamboo and can grow quickly up to 45 feet (14 m) with an average diameter of 5 inches (13 cm).
These plants have green stripes on yellow canes and usually feature large leaves. These plants grow to around 35 feet (11 m), starting a light green color and turning gold with sunlight.
The underground rhizomes of this running bamboo can get quite invasive, so you want to prevent an extreme spread. Phyllostachys Irides This is another timber bamboo that grows rapidly especially in warm climates.
They do require a large amount of sun each day and should be placed in a sunny area. The only real thing that can affect bamboo growth significantly is to be planted in an area that has poorly draining soil or is consistently wet and boggy.
When bamboo is planted in soil that is overly saturated, it can suffocate the roots and cause them to not get the air they need. If the area you plan to plant the bamboo is overly saturated, there are some things that you can do to improve the drainage and increase growth.
The tallest species of bamboo was found in the tropics and was reportedly 130 feet (40 m) tall. If you are hoping to plant bamboo, you will want to do your research and be ready before Spring hits.
