The answer to 'why is my paver weeds' is that weeds can often grow in between paver stones or bricks, especially if the joints were not properly filled. Common causes include inadequate joint filling material, poor drainage, and lack of maintenance.
Some common symptoms include weeds popping up between pavers, the pavers becoming uneven or shifting, and the overall appearance of the patio or walkway becoming unkempt. Solutions can include removing the weeds, refilling the joints with sand or gravel, and improving drainage to prevent future weed growth. For significant weed issues or uneven pavers, it's best to call a professional landscaper to assess the problem and provide the proper fix.
