Bamboo Planting Guide:
All our bamboo varieties are clumping, meaning they grow out in circle around a central point. For a dense screen you would plant each bamboo the same distance apart as the width of the bed ie for a 90cm bed plant them 90cm apart. The minimum bed width and planting distance is dependent on each variety.
Bamboos are shallow rooted, with roots growing to a maximum depth of between 30cm and 50cm. They are adaptable to a wide range of soil types from clay to sand, but resent being waterlogged regularly. It is often ideal to introduce a good depth of quality topsoil for them to grow in and for them to be mulched and fertilized regularly, however this is not a necessity.
Planting can occur at any time of year, except in areas with heavy frosts where it is advisable to not plant in winter.
Standard planting practices apply: dig a hole twice as wide as the pot and about as deep with plant sitting at soil level. Turning organic matter in is desirable for quick and easy establishment. Particular emphasis should be placed on thoroughly watering in the plants.
Bamboos benefit from being well mulched. They require regular thorough watering until establishment, at which point watering needs will ease off. They benefit from the application of fertilizer high in nitrogen over the growing season. Over time when old culms begin to die off, they should be removed to maintain lush appearance.
There are 4 main ways to prune bamboo:
- Prune to height: Just like with trees and shrubs, bamboo (excluding Tiger Grass) can be pruned to maintain a desired height. This can also be used to keep bamboos narrow and not spilling over into pathways or over roofs. Pruned culms will not regrow however new shoots will need to be pruned once they reach the height.
- Thinning: Selectively removing culms from ground level will open up the canopy and decongest the “trunk” level.
- Removing side branches: To achieve a sleek display of the culms and to neaten the canopy, remove side branches to a chosen height.
- Knocking out new shoots: This will control the size of the bamboos footprint but also allow you to maintain a desired density. Simply kick or knock over new shoots at they emerge while they are still soft.
Bamboos are an excellent screening option for traditional and modern landscapes alike. Instead of just blending into the background they are a feature in themselves, bringing texture, colour and sculptural form to the garden. With such diversity in size and shape there are endless ways to uses them, with smaller varieties even making great pot specimens.
