Using Yellow Groove Bamboo over this 270′ border will give us an effective screen in a relatively short time, and at a reasonable cost. But Yellow Groove happens to be of the “running” type, meaning if not contained its roots (rhizomes actually) will run and invade in all directions.
Planting any invasive plant is serious business. First off know what you’re planting and what it can potentially do. You could be a hero the first year it grows and a “scoundrel” the second year as it invades the neighbor’s yard.
Root Barrier From Day 1
The homeowner didn’t hesitate to authorize the root barrier install. It solved the concern of “running” bamboo and let the plant’s good characteristics shine.
After clearing and rough grading the area, the mini-excavator dug a trench around the perimeter of the planting bed.
This particular bamboo root barrier is made of high density polyethelene and comes as a roll. Different widths are available and here we used 30″ wide. You want to install it so that a few inches are above final grade. This protruding collar will help stop and deflect “runners” that are close to the surface. A good maintenance practice would be to occasionally monitor this barrier just in case some Houdini-like runner makes it over.
We’re starting with bamboo in 5 gal. containers from Monrovia Nursery. They’ll stand around 5-6′ tall when planted. As you can see in the picture to the left, the plants are arranged in 2 staggered rows with 6′ C-C (center-to-center) spacing.
The irrigation contractor did install a “drip-zone” before the mulch went down. Once the bamboo is established I really don’t think scheduled watering will be needed. It is zoned separately so it can be adjusted however necessary.
In this circumstance and with the root barrier installed the bamboo offers an excellent screen. It won’t be long before it grows into the 12’+ privacy hedge the homeowner is looking for.
Bamboo, like so many areas in landscaping, could be a study unto itself. There are numerous types and varieties along with many different ways to use them. How about yourself?…Have you had any experience(s) working with bamboo?
Here’s the previous post for this project.
