It's important to be
careful when killing ornamental grass, as some methods can harm surrounding plants. Here are some effective and safe options:
1. Digging & Removal:
* Best for small clumps: This is the most labor-intensive but ensures complete removal.
* Dig deeply: Get as much of the root system as possible.
* Dispose properly: Don't compost ornamental grasses, as they can spread. Bag and discard them.
2. Herbicides:
* Use with caution: Always read and follow the label instructions carefully.
* Glyphosate-based herbicides: Effective but can damage other plants.
* Selective herbicides: Choose one that targets grasses, not flowering plants.
* Apply carefully: Avoid spraying onto surrounding plants or foliage.
3. Covering and Suffocating:
* Solarization: Cover the grass with clear plastic sheeting for several weeks during hot weather. Sunlight will heat the soil and kill the grass.
* Cardboard: Cover the grass with several layers of cardboard and mulch on top. This will block sunlight and eventually decompose the grass.
4. Repeated Mowing:
* Keep cutting it down: This can weaken the grass over time.
* Mow very low: Cut the grass as close to the ground as possible.
* Be persistent: It may take several weeks or months for this method to work.
5. Boiling Water:
* For small areas: Pour boiling water directly onto the grass. This method can be effective but may not kill the entire root system.
* Use with caution: Avoid getting boiling water on surrounding plants.
Important considerations:
* Identify the type of grass: Some grasses are more difficult to kill than others.
* Time of year: Herbicides are most effective during periods of active growth.
* Soil conditions: Dry soil may not be suitable for certain methods.
* Environmental impact: Consider the impact of your chosen method on pollinators and beneficial insects.
If you're unsure about the best method, contact a local gardening expert or your local extension office for advice.
