The answer to 'deck overgrown' is that a deck can become overgrown due to lack of regular maintenance, such as not clearing away leaves, debris, and plant growth. This can lead to the deck boards becoming slippery and unsafe, and the overall appearance becoming unkempt. To address an overgrown deck, you'll need to clear away the excess growth, clean the surface, and potentially apply a sealant or stain to protect the wood.
If the overgrowth is minor, this is a task that can often be handled through DIY efforts. However, if the deck is significantly overgrown or the wood is damaged, it's best to call in a professional landscaper or deck specialist to assess the situation and provide the appropriate solution.
