Bark is beautiful. 🌳 Come see for yourself!
Each species has a characteristic color and texture to its bark. 🌈
Bark isn’t just for looks—it’s a tree’s armor! 💪

With cold temps ahead, you may hear about “exploding trees” — but it’s not that explosive. 🌳❄️ Sudden cold rarely causes this. What’s more common is frost cracking, when bark warms in the sun, then cools and shrinks faster than the inner wood, creating a vertical crack. Learn more: bit.ly/4a9Lb8k.
