I've never been much of a gardener, but I've become a bit of an accidental tree-watcher since moving to Wales. Between our hikes through the countryside and my endless fascination with anything that grows without complaining, I've picked up a few strange little facts that have stopped me in my tracks. For example, when drought hits, a healthy tree doesn't just stand there and wilt dramatically as I would. It has an ingrained survival strategy.

The tree stops producing new leaves. It pulls back from growth mode and turns its energy inward. And then, rather than throwing a fit about the lack of rain, it sends its roots down deeper into the soil, searching for whatever moisture is still hiding beneath the surface. The tree essentially says, "Fine. If it's not coming from above right now, I'll go find it below." No drama. No dying. Just digging.
