The answer to 'mulch invasive plants' is to use mulch carefully and selectively to manage invasive plants. Mulching can be an effective way to suppress the growth of some invasive plants, but it must be done properly to avoid inadvertently spreading them further.
Invasive plants are aggressive and can quickly take over a garden or landscaped area. Mulching around these plants can help block sunlight and prevent them from spreading, but it's important to use the right type of mulch and apply it correctly. Organic mulches like wood chips or shredded bark are generally better than inorganic options like gravel or rubber, as they can actually smother and kill the invasive plants over time. However, you need to be careful not to spread the seeds or plant parts of the invasive species when applying the mulch.
