It's the same for my peach tree that is covered from top to bottom with the netting. IHowever it's not enough to throw a net over the tree and hope it will deter the birds because they are cunning enough to get in underneath or through a hole where the net doesn't meet. Hence the pegs.
Now I have to undo the pegs and climb in through the hole to collect the fruit. A small act of contortion. Just as well the peaches are delicious!
