Hello!
Getting rid of hardy bamboo in your lawn and garden can be challenging due to its robust growth and extensive root system. However, you can control and eventually eliminate it with persistence and the right methods. Here are some steps to effectively remove bamboo:
1. Physical Removal
Digging Up
- **Dig**: Use a spade or shovel to dig up the bamboo shoots and as much of the root system (rhizomes) as possible. Bamboo roots can extend far and wide, so be thorough.
- **Remove Rhizomes**: Dig deep (at least 2 feet) and wide to ensure you remove all the rhizomes, as any remaining parts can regrow.
Cutting and Mowing
- **Cut Shoots**: Regularly cut bamboo shoots down to the ground level. This helps to deplete the energy stored in the roots over time.
- **Mow**: If the bamboo is in a lawn area, regularly mow the area. This can weaken the bamboo and prevent it from growing back robustly.
Barrier Methods
- **Install Barriers**: Create a physical barrier to prevent bamboo from spreading. Use high-density polyethylene (HDPE) or metal sheeting to create an underground barrier around the bamboo area. Dig a trench at least 2 feet deep and insert the barrier, ensuring it sticks up a few inches above ground to prevent rhizomes from growing over it.
- **Root Pruning**: Regularly prune the roots that escape the barrier.
Herbicides
- **Select Herbicide**: Use a glyphosate-based herbicide or a bamboo-specific herbicide. Be cautious and follow the manufacturer's instructions.
- **Apply Herbicide**: Apply the herbicide to cut bamboo stumps or new growth. Repeat applications are often necessary for complete eradication.
Caution: Avoid using herbicides near other plants or water sources to avoid unintended damage.
Solarization
- **Cover with Plastic**: In sunny areas, you can cover the bamboo-infested area with thick black plastic sheeting.
- **Secure Edges**: Ensure the edges are securely fastened with rocks, soil, or stakes to keep the plastic in place.
- **Leave in Place**: Leave the plastic covering for several months to a year. The heat and lack of light will kill the bamboo.
Regular Monitoring
- **Inspect Area**: Regularly inspect the area for new shoots and immediately remove them.
- **Persistence**: Bamboo is persistent, so your efforts need to be consistent and persistent over time.
Tips
- **Patience**: Removing bamboo can take time. Be patient and persistent with your efforts.
- **Dispose Properly**: Dispose of the removed bamboo properly. Do not compost it, as it may regrow.
- **Consult Professionals**: If the infestation is extensive and difficult to manage, consider consulting a professional landscaper or pest control expert.
By combining these methods and maintaining regular control efforts, you can successfully remove hardy bamboo from your lawn and garden.
