I have some grape plants coming in next year. My plan is to make a sort of trellis-fence to partly break up the view of the road from my yard, and of course help the grape plants vine out.
What's the ratio for post that's buried in the ground vs post that's showing above ground?
I live in Zone 6, so we have some pretty mild winters (rarely gets below 0, never below -10 I think). I was thinking of using just 4x4 posts with about 8 feet above the ground. I was thinking maybe I would put 3 feet in the ground and have 8 feet above. Would that be enough?
The ground here is made of about half dirt and half clay. So I would imagine it would hold the posts pretty well.
