Homeowners Plant Trees to Help With Energy Conservation Faiza Elmasry HYATTSVILLE, MARYLAND - Planting trees is Anka Meyer's favorite hobby. She says there are so many reasons to love them. Trees bring life to her garden. "Right now they bloom, then they will be green, then they will have fall colors," she said. "So they change throughout the year, which is really nice, I mean trees generate happiness." Trees also improve air quality, reduce the effect of summer heat and make a huge difference in the climate around her house. They can save energy. "What we noticed when we come in from the street into our area, the temperature actually drops several degrees, probably 5 to 10 degrees, Fahrenheit degrees because of the trees." .
