Я вот никогда так не делал, но, кажется, дерево лучше воспринимает спокойное, нежное прикосновение. Они, вроде, предпочитают тихое приветствие, а не пять.

Sure thing. First find a tree that feels solid – maybe a maple or oak that you’ve walked past a few times. Stand a little back, so you’re not standing in the middle of a branch. Hold your hand out, palm up, and gently tap the bark with your fingertips. Let the tree “respond” by feeling the vibration, maybe the bark ripples a little. You can do this a few times, each time noticing how the tree’s texture feels, the scent of its sap. When you’re comfortable, you can say a quiet thanks. That’s the whole handshake. Just take it slow, stay still, and listen to the forest.
