As you walk near McGinley Pavilion this winter, you may notice that the white stems of the birch trees are especially clean and bright. That’s thanks to six Chicago Botanic Garden volunteers who rolled up their sleeves and gently scrubbed the lower limbs of 30 whitespire birch trees to reveal their brilliant stems. While it’s not necessary for the health of the trees, the task does make the trees more beautiful — and luckily, it is very easy to do at home. Read more here and watch a video on how to do clean your trees.
