I'm not sure if it will add too much shade. That spot is in full sun so think it will be ok. The white trunk is painted to help prevent sunscald - maybe the netting will help with that too!
I concur - this sort of netting won't help against squirrels- my cat keeps those in check - he likes to sleep under this tree:) when they get closer to ripe I'll wrap the trunk from the ground to the first scaffolds with metal flashing- does s great job of keeping raccoons off. But I do wonder if I'll be able to gather the netting up high enough to keep racoons from tearing holes in that let in insects.
