Non-Invasive Bamboo - What Bamboo Does Not Spread?

Non-Invasive Bamboo – What Bamboo Does Not Spread?

We often hear that people say bamboo is so invasive. This doesn’t go for every kind of bamboo though.

Clumping bamboo is the non-invasive type. There are specific techniques on how to prevent bamboo from spreading.

Now you are probably thinking: “Ok, clumping bamboo. But what is it, what species are clumping bamboos, and what techniques can I use to prevent spreading?”. We hear you!

Bamboo roots are mostly superficial. Rhizomes commonly develop within the initial six inches underground. They create feeder roots that stretch further underneath the soil. Normally, the roots do not spread any more than 20″ inches beneath the ground. Bamboo rhizomes develop in two different ways. Some develop in a clumping or running form. Bamboos are determined either as clumping or running bamboo.

What is a clumping bamboo?

Clumping or sympodial bamboo is the non-invasive type. It has Pachymorph or U-shaped rhizomes that develop upwards and grow into a fresh culm then brand-new rhizomes appear from shoots on a present rhizome and so on and so forth. This chain effect generates the woods to increase moderately throughout the boundary. This maturity course gives the bamboo a ‘clumping’ way and further extension is expected and manageable. They may attain a maturity height in four to six years following optimal growing circumstances. Due to the anticipated germination pattern, a restriction is not required anymore. But specific maintenance still needs to be understood.

Clumping bamboos can survive drought better than runners. They burrow reasonably deep. Most hardy clumpers are shade admiring plants, but there are also some species that are sun-loving. There are also many bamboos that possess dark canes and some that are cold-hardy. Some of them never grow big.

The compact and solid roots develop in a compressed clump and increase gradually. Clumpers are just confined in the fields they grow. As a matter of fact, clumpers are not natively adapted to increasing more than several inches in one year. They maintain a pretty short root system. They are genetically incapable of extending more than a few inches per year and will usually produce discrete clumps. Every brand-new rhizome offers only a sole culm, found so close to its parent culm.

They go higher, growing canes quickly, and are easy to control. Sadly, not many of them are cold hardy. So, these bamboos are challenging to produce outside of zones 8 to 10. The cold-hardy clumping species which are chiefly mountain bamboos are very restricted in the climate zones they exist in.

The south clumpers are giants and progress so quick just like running bamboos. The obstacle is the restricted climate zones and the distribution of the canes in the clumper. The spaces within the canes are so small that most parts are very deformed due to a large number of dead canes and branches in the center of the clump. These impenetrable dead canes and branches are so hard to reach except if any of the outer canes are cut off first. Some tropical clumpers are badly managed and are hideous which gives bamboo a poor image.

What are the advantages of clumping bamboos?

  • Have a superficial, non-invasive root system
  • They will not break away from containers
  • A quick growing grass type
  • Great wind protection, sound barriers, and privacy protection
  • Some can be raised in containers, gutters or raised beds
  • Drought tolerant
  • Some can be grown in confined areas
  • They can be trimmed or shaped
  • They develop in several attractive and interesting patterns, colors, and measurements
  • Prevent soil erosion
  • They can cool your garden especially in summer
  • They purify air compared to other plants of its size

What are the different techniques of planting non-invasive clumping bamboo?

Culm planting

Culm planting has several benefits like easy, high survival and maturity rate. Aside from the variety of culm with or without its end, the entire culm or portion of it can be utilized. The last-mentioned with stump is the safest method because that part can increase the node shoots to germinate.

This process defeats the problem that most shoots on the culm don’t grow in developing culm plantings. The internodes of the stump and culm are not skipped off entirely, and the stump can furthermore be carried for sowing throughout its initial maturity days.

Layering

This is appropriate in the scattered bamboo platforms placed on smooth grounds.

Rising from the center of chosen parent bamboos, dig a straight channel.

Cover the soil in the base of the trench, feed with compost, and stir the manure and soil completely. Slice a chunk at the base and at the backside facing the trench.

Put the twigs and leaves of the initial node in the top part of culm, for other internodes just keep the central branch with two to three internodes and buds on every node and split off the other branches throughout the culm.

Force the parent bamboo gently into the trench, and coat it with a layer of 2 inches of soil and squeeze the covered soil firmly, simply exposing the leaves and branches of the end node.

Lastly, spread it with some straw and water it.

The nodes will grow roots and shoots throughout 100 days. In the following year saw off every internode into a self-supporting plant. Dig out those plantings and prepare them for planting new bamboos or transfer them into nursery ground for breeding plantings repeatedly.

Planting nodes

This scheme involves establishing one or two noded culms.

Slice the tip of a culm, saw it into one-node or two-node pieces. A two-node culm is planted horizontally and a one-node culm is somewhat slanted or erect. Leave about 4 inches above the node and up to 10 inches underneath the node when sawing a one-node culm.

The extent of the two-node culm may be smaller than that of the one-node culm. The parts can be horizontally sawed. Be careful not to damage the culm. Plant one-node culm horizontally and make the nodal shoots face upwards.

Planting stump

The end of the bamboo can be harvested together. Healthy stump is the best thing for the new generation.

Protect the roots from damage when digging. They can be divided into halves for reproduction, and every half will produce roots and shoots. Trench and plant the stump horizontally or vertically. Then wrap it with 1 inch of soil and push the soil tightly.

Lastly, cover it with some hay and water it. Usually, the stump can produce shoots and spread roots in 30-50 days. It can be harvested and transplanted in the next season.

Branch cuttings

Branch cutting has two types which are the main and the sub-branch. The central and sub-branch cuttings can be used for reproduction. They produce adventitious buds that germinate and spread roots. This doesn’t harm the parent bamboo. The branches are easy to move. The survival rate is guaranteed.

Select branches which are solid and strong, with small internodes, and with plump buds on its first to third nodes and huge branch support with roots sprouting detail.

They will grow into young plants in 3 months.

They can be transplanted in 4 to 5 months after. The best time to do this is from March to April. Growing plantings by branch cutting have advanced quickly.

Bamboo confinement

It is not required or even useful to enclose your clumping bamboo with a plastic root partition. But if unavoidable, they can be trimmed. Just remove further shoots at ground level. The root ball of a clump has to be left to occupy a particular size in order to produce culms of adult height.

The area needed may differ depending on the size of a variety. The extent of culms can be defined if too little space is left for its roots. These bamboos won’t be able to adjust their round aspect to a long, narrow scope, and its height may be restrained if there is limited room left for the roots. It is recommended to plant them for about 2 to 4 feet away from a wall to provide some opportunity for growth and area for managing between your bamboo and the wall.
