The cost of PVC pipe and a net to cover a 30 X 80 foot garden would be prohibitive.
Can you give a few details of the fence (especially since it is working)? We have deer .... and groundhogs. I’ve been using a portion of my sister-in-law’s raised bed garden next door - they have a dog that keeps the deer & chuckies away. This year, I’m putting the garden on my property, closer to the house... no dog ... so I need to plan for 4-legged invaders.
I’ve heard the secret of keeping deer out is to play upon their natural fears of being enclosed.
Sure, they can jump a 6 ft fence,
but if, in doing so, they are in an enclosure that bothers their “claustrophobic” tendencies, they won’t do it.
So, for fruit trees, a 5 ft fence far enough back from the tree that they can’t reach over, but close enough to be “confining”, will deter them.
But, so will a Great Pyrenees.
More info on the fence, please?
An elderly man shared a tip with me regarding using an electric fence to keep agressive deer out of the garden. He said to smear peanut butter in several locations on the electric fence (be sure to turn it off first :-)). Since deer are attracted to peanut butter, when they stick their nose or tongue to the wire, they get the shock of their life and won't ever come back.
My brother watched a doe do this last fall when he employed the trick. He said when the doe stuck her nose to smell the peanut butter, he saw the blue zap hit her in the nose, and said she did a double back flip and flew past him at blazing speed. He still laughs when he talks about it.
4 row electric fence around our 75’ x 75’ garden is worthless against our deer. But then we live in the woods and often have 9 or 10 grazing below our deck first thing in the morning.....
