I live in upstate NY about 2 hours north of NYC. As such the climate is humid in summers and cold and snowy in winters. Anyways I'm building my first grape trellis and I plan on planting chardonelle grapes.
I purchased pressure treated 4 x 4 wood end posts. They are 8 footers. I used a post hold digger and was able to dig down 30 inches. Will this be deep enough?
The end posts are 20 feet apart on a slight hill. I will use intermediary metal posts in between to add strength.
My question is is the 30 inches deep enough? Also do I need to fill the hole at all with gravel or concrete or just fill it in with dirt. I also plan on tying the end posts back with metal anchors that twist into the ground.
