The chicken wire only goes up 2' and stays year 'round - easy for me to step over for grafting, etc. No netting on these at this time. Bird netting is draped over top support line only as needed and reaches down to chicken wire. Bird netting easily moved for harvest and taken down after harvest. It is only needed, say 2 months of the year.
Weeds stiffled by leaves held in by chicken wire. Need occasional maintenance - not bad at all.
Yep. Backyard sounds like a bird sanctuary.
Doesn't. It's an internet legend promoted by theoriticians in ivory towers that don't grow squat.
