The answer to 'retaining wall has weeds' is that weeds growing in a retaining wall are a common problem caused by soil, moisture, and lack of maintenance. Weeds can take root in the cracks and crevices of the wall, compromising its structural integrity and creating an unsightly appearance. Symptoms include visible weeds, loosening of wall materials, and potential damage to the wall over time.
To address this issue, homeowners can try DIY solutions like manually removing weeds, applying a weed-killing herbicide, or sealing cracks. However, for more severe weed infestations or structural concerns, it's best to call in a professional landscaping contractor who can properly assess the wall and provide long-term solutions to prevent future weed growth.
