i just got back from watering them about 10 minutes ago, and when i got down there to the biggest one, a bunch of branches were all tangled up. i untangled them, and none were broken. i then noticed a branch hanging much lower than usual. i dont think it was caused by weight, because it isnt that heavy yet, but it is not broken either. a little confused, what could be doing this? a small animal like a raccoon or skunk? but how would the tangling of the branches be explained? anyone know?
