Two seasons ago, my parents young longan was completely stripped of it fruit by something. Last year, they ended up picking they’re fruit a little early so, somewhat less sweet that it could have been. This year they asked me to build something to protect the fruit. Here is the tree as it looks now.

It’s doable now but it will probably outgrow it by next year. Any suggestions to protect from critters or is it just do what I can for now and eventually the tree will grow big enough for everyone and everything?
