Learn about, play on, and celebrate Texas trees at a free event this weekend that includes fun events for the whole family. It’s all happening at the Tree Talk Winter Walk event at the Texas Arboretum at Lady Bird Johnson Wildflower Center on Saturday, Jan. 25 from 9 am to 5 pm. Kids can climb trees with professional arborists, build a fort with tree limbs and branches, go on a tree scavenger hunt and more while adults learn tree care tips and purchase native woody species for planting.
