It's not recommended to kill the grass growing in your myrtle bush. Here's why:
* Myrtle is a shallow-rooted plant: Killing the grass around it could disrupt the root system of your myrtle, making it more vulnerable to drought and other stresses.
* Grass can provide benefits: The grass can help to suppress weeds that could compete with your myrtle for resources.
* Mulch is a better solution: A layer of mulch around your myrtle will suppress grass growth, retain moisture, and protect the soil. You can use wood chips, bark, or even shredded leaves.
Instead of killing the grass, try these methods:
1. Mulching: Apply a 2-3 inch layer of organic mulch around the base of your myrtle, leaving a small space around the stem.
2. Hand-weeding: Carefully pull out any individual grass blades that pop up within your mulch layer.
3. Selective herbicides: In extreme cases, you can use a selective herbicide specifically designed for broadleaf plants. Be extremely cautious with herbicides, and always read and follow the label instructions.
Remember: It's generally best to encourage beneficial plants like grass in your garden, especially around shrubs like myrtle. They help maintain soil health and prevent erosion. Focus on managing the grass rather than killing it completely.
