All the more reason to just wrap the netting (or even chicken wire) around the trunks/hang it from the branches, as those materials naturally have some give.They certainly do. Now I’m wondering how much they move around.
Downside (and I deal with this because I have a weeping willow over my run, so it grows into the run netting each spring) is you're probably going to have to do annual checks/maintenance on the netting/wire and adjust for any tree growth, do pruning or debris clean up, etc.
