BAMBOO ROOTBARRIER
A bamboo root barrier is a physical barrier designed to prevent running bamboo species from spreading beyond their intended area. Here’s how to create and maintain an effective root barrier:
1. Material Selection
- Plastic or Composite: Use high-density polyethylene (HDPE) or other durable plastic materials. Some composite materials are also effective.
- Depth: The barrier should be at least 24 to 36 inches deep, depending on the species and its growth habits.
2. Installation Steps
- Plan the Layout: Determine the area you want to contain the bamboo and mark the boundaries.
- Dig a Trench: Dig a trench around the marked area, ensuring it’s deep enough to accommodate the barrier.
- Install the Barrier: Place the barrier vertically into the trench. Ensure it’s at least 1-2 inches above ground to prevent rhizomes from arching over the top.
- Backfill the Trench: Refill the trench with soil, compacting it around the barrier to secure it in place.
3. Maintenance
- Regular Checks: Periodically inspect the barrier for any signs of damage or root escape.
- Trim Roots: If any rhizomes grow close to the barrier, trim them back to keep them from breaking through.
4. Consider Alternatives
- Concrete or Steel Barriers: In high-growth situations, consider using concrete or metal for a more permanent solution.
- Planting in Containers: For smaller areas, planting bamboo in large pots or containers can also effectively contain growth.
Although Bamboo is a very versatile plant it grows best in well areated soil that is light in structure and rich in organic nutrients, ideally it should have good drainage but still retain some moisture. To promote growth and to help with keeping your plant looking lush and green feed with a general purpose organic liquid food during the growing season. If planted in a pot ensure an adequate water supply at all times. This plant need has no special requirements during the winter months. Awarded RHS Award of Garden Merit.
