TREES & plants. Sweet birch. Sweet birch is an attractive tree for lawns and naturalized areas, with shiny, red-brown bark and yellow foliage. Native to the eastern United States, the tree also attracts beautiful butterflies to the landscape, serving as a caterpillar/larval host. This species is resistant to bronze birch borer (BBB).
Yellow leaves are typical in fall, but not in summer. Birch trees (Betula spp.) add interesting architectural form to your garden landscape. They thrive in U.S. Department of Agriculture plant hardiness zones 5 to 8, though the specific zone varies by species. Most birches produce leaves that yellow and drop in fall. If it's still summer and your birch tree leaves are turning yellow, the tree is telling you it has a problem. Most issues are easily resolved.
