The answer to 'why is my deck dead trees' is that there are several common causes for dead trees on a deck, including improper soil drainage, insufficient sunlight, and pest infestations. Dead trees on a deck can be a serious issue, as they can compromise the structural integrity of the deck and pose a safety hazard.
One of the most common causes of dead trees on a deck is poor soil drainage. Decks are often built on compacted soil or over concrete, which can prevent proper drainage and lead to waterlogging around the tree's roots. This can cause the roots to rot and the tree to die. Another common issue is insufficient sunlight. Many trees require at least 6 hours of direct sunlight per day to thrive, and if the deck is shading the tree, it may not get enough light.
