In order to keep chemicals out of the garden we choose not to use pressure treated fence post. The were a few cedar trees that had been pushed into a big junk pile with lots of big weeds when we arrived on the farm. It took a while with hand tools to clean the pile of rubble up, but I did save the cedar. I cut the cedar into post lengths and then split the logs, getting about four posts per section of log. I used the cedar at the corners and where the gates are. I put a six foot gate on each of the four sides of the garden, to make getting mulch and compost in easier. In between the cedar posts I used metal T post to give the fence strength. I used four foot fencing with 2 inch by 4 inch mesh. When I fenced in our round garden/rabbit areas I used a five foot fence. If I had to do it all over I would have used five foot fencing for all gardens. Using extra tall corner post makes for a nice birdhouse spot.
The gate frames are about 4 inches shorter than the fence. The area of fence above the frame makes for an unstable place. If the frame were to go all the way up the chickens would jump up, rest, and then down into the garden to feast.
We do a lot of vertical planting (that will be its own topic) and the first time I was using the fence to plant sugar snap peas the chickens watched me. After I left the garden area, the chickens went back and retrieved most of the peas before they sprouted. When planting on the fence, the chickens get some cucumbers and tomatoes, I don’t mind sharing. In order to protect the peas on the fences I put a line of two foot chicken wire at the bottom on the fence line and now we get our peas to grow.
It is almost time to plant peas again, enjoy the cool weather while it last.
