The answer to 'deck has weeds' is that weeds can commonly grow on decks due to a lack of maintenance, poor drainage, or gaps between boards. Symptoms include unsightly growth, damage to the deck structure, and potential trip hazards. Solutions include regular weeding, applying herbicides, and sealing or replacing the deck as needed.
For minor weed issues, homeowners can often address the problem themselves through DIY methods. However, for more extensive weed growth or structural damage, it's best to call a professional landscaper or deck specialist to properly diagnose and resolve the problem.
