Ni Hao, Bamboo

March 23, 2017

Bamboos are wonderful garden plants, grown primarily for their architectural stems (canes) and their foliage. These members of the grass family look fantastic in modern gardens--where their upright habit makes a fashion statement  --as well as in more traditional gardens. They are fantastic backdrop plants, where the elegance of their canes and foliage frames the garden and helps set off other plants.

 

Bamboos are also very versatile. They can be used for hedging and screening, low-growing ones can be used as ground cover, or taller ones can be planted as individual specimens. Many are ideal for growing in containers. They provide a tropical, almost jungle, feel to any garden and need very little looking after. And, of course, you can cut out the canes to make your own plant supports!

 

How to Grow Bamboos
Cultivation
Bamboos are easy to grow and are fine in just about any soil and most situations, except in permanently waterlogged or extremely dry soil. Some species do prefer a sunny site, others like shade, but most have little preference.

 

Suggested Planting Locations and Garden Types
Flower borders and beds, patios, containers, city and courtyard gardens, hedges and screens.

 

How to Care for Bamboos

 

Bamboos need very little regular care and attention--apart from pruning out old canes--and they rarely suffer from any pests or diseases. Water during prolonged dry periods, especially for the first two years after planting, as this will keep the bamboo healthy and ensure a steady production of new canes. Feed in spring with a granular feed and cover the soil with a 2-3 in. deep mulch to help keep the roots cool; this will help rapid establishment and development.

 

New canes grow taller and thicker each year until the clump reaches maturity, usually after 8 to 10 years. It is then worth cutting out old or weak canes and thinning out in spring to allow space for the new, younger canes. Contrary to popular belief, bamboos do not always die after flowering. More often than not there will be plenty of non-flowering canes that continue growing. In any case, flowering is an infrequent occurrence, and any flowered canes should be pruned out.

 

Controlling Bamboos
Some bamboos have a reputation of being invasive garden thugs--spreading by underground rhizomes that take over the garden. It’s true that some bamboos do spread to make large thickets of canes, but there are many well behaved species that don't. Even those that do spread can be tamed; plant them in bottomless buckets or similar to contain the spread of their roots. Make sure the lip of the container is above ground level or the roots may spread above it. If you do inherit a garden that contains a spreader, or you have inadvertently planted one, check regularly and cut through the unwanted roots with a good garden shovel or saw.

 

Types of Bamboos
When choosing a bamboo, consider its height and spread and grow one that is suitable for the space you have. One drawback to bamboos is their long and almost unpronounceable botanical names. And many bamboos have undergone re-naming to add to the confusion. The following are all excellent garden plants.

 

Chusquea culeou

This bamboo produces dense clusters of canes, making it ideal for specimen planting as the stiff, solid canes radiate out creating a striking effect. It grows to 13 ft. high. The canes are olive green at first and mature to yellow or yellow brown. A clump former for sun or semi-shade.

  • Suitable for producing cut canes

  • Suitable for cold and exposed gardens

  • Suitable for hedging and screening

  • Good specimen plant

 

 

Fargesia murieliae (Arundinaria murieliae)

This widely planted species is a well behaved clump former growing to 10-13 ft. high. The canes become yellow-green as they age and the foliage is pea green. Simba is a smaller variety, only reaching 6 ft. high.

  • Suitable for producing cut canes

  • Suitable for cold and exposed gardens

  • Suitable for hedging and screening

  • Suitable for growing in pots

  • Good specimen plant

 

 

Fargesia nitida (Arundinaria nitida)

Another well behaved clump former. It grows upright to 10-13 ft. high and spreads slowly. The canes mature to dark purple. Prefers light shade and moist soil.

  • Suitable for producing cut canes

  • Suitable for cold and exposed gardens

  • Suitable for hedging and screening

  • Suitable for growing in pots

  • Good specimen plant

 

 

Phyllostachys aurea

This bamboo grows to 13 ft. high and produces dense foliage, making it perfect for screening. Needs a sunny site for the green stems to turn yellow. Will tolerate dry soils.

  • Suitable for producing cut canes

  • Suitable for hedging and screening

  • Suitable for growing in pots

  • Good specimen plant

 

 

 

Phyllostachys aureosulcata Spectabilis

This produces spectacular yellow canes with green marks. It should be planted somewhere that it can be fully appreciated. It has an upright habit reaching up to 15 ft. high. It is an ideal specimen plant for a cold garden.

  • Suitable for cold and exposed gardens

  • Suitable for hedging and screening

  • Suitable for growing in pots

  • Good specimen plant

 

 

Phyllostachys nigra

The black bamboo grows to 8-13 ft. The jet-black canes develop by their third year and turn black more quickly in a warm sunny, drier site. An excellent bamboo for containers.

  • Suitable for cold and exposed gardens

  • Suitable for hedging and screening

  • Suitable for growing in pots

  • Good specimen plant

 

 

Pleioblastus auricomus (Arundinaria viridistriata)

This colourful bamboo spreads slowly and is easy to control. The brilliant yellow leaves are irregularly striped green and the canes are purplish-green, reaching 3-4 ft. high. Grow in full sun and cut down to ground level each spring for the brightest colouring on the new growth.

  • Suitable for growing in pots

  • Good specimen plant

 

 

 

Pleioblastus variegatus (Arundinaria variegata)

An easy to control, mound-forming bamboo growing to 3 ft. high. It has very ornamental creamy-white variegated leaves and an upright habit. It is best grown in sun or very light shade, as the variegation is less marked in shade.

  • Suitable for growing in pots

  • Good specimen plant

 

 

 

 

Pseudosasa japonica

A well behaved, clump forming bamboo reaching 11 ft. high. The slim canes are olive-green when young and produce large, glossy green leaves that are grey underneath. It tolerates very wet conditions.

  • Suitable for producing cut canes

  • Suitable for cold and exposed gardens

  • Suitable for hedging and screening

  • Suitable for growing in pots

  • Good specimen plant
