2. Understanding Deciduous Trees
Before we dive into the reasons behind early leaf drop, let’s take a moment to appreciate deciduous trees. These magnificent woody plants, including maples, oaks, and birches, are known for their seasonal leaf changes.
During the growing season, their lush green foliage transforms into a breathtaking array of reds, oranges, and yellows.
Sustainable landscaping goes beyond aesthetics, emphasizing practices that benefit both your home and the environment. From essential water conservation, to mindful plant choices, discover the key elements shaping eco-friendly outdoor spaces.
3. The Beauty of Autumn Leaves
