This is the link to how I built my Plant Protection Cage:    • Building a Plant Protection Cage on W...  
It is a 100% protection guarantee against the little critters that go boo in the night (and even in the daytime for that matter).
I have many fruit trees and a vegetable garden, both of which are nicely productive. But I have found it necessary to harvest early, while the fruits are still green, otherwise I will see none of my labor come to fruition. Rodents, for whatever reason, will often dig up seedlings and even go so far as to eat them. Therefore, I built this Plant Protection Cage about a year ago; I will now be able to enjoy fully ripened vegetables fresh from the vine!
