As we close in on the end of the growing season, it's time to build a permanent garden solution vs the t-posts and chicken wire we used this year while evaluating the site location. Looking for any feedback from folks on ways to improve or mistakes I may be making...
Looking to build a fence around our garden area similar to shown in the photos here:

I've worked up my own plans based on the photos, but haven't build anything like this before so may be making some bad assumptions. Here's what I'm planning:
- Fenced area will be 35ft x 35ft (approx)
- Posts: 6x6 corners and either side of the door; 4x4 elsewhere, all buried 3' deep. Will fill bottom of hole with 3-4" of gravel and then use 2 50lb bags of quickrete to set the posts. Will backfill the rest with our clay dirt here in TN.
- All ground-contact rated pressure treated lumber (YellaWood SYP).
- Will use 5' tall 6 gauge livestock panels with 4x4 openings.
- 64" span between posts, so each panel will be 60"x64" and weigh 16 pounds.
- 2x4 top and bottom rails holding the panels, which will be toe-nailed into the posts (will use a framing nailer for the build)
- Will rip 2x4s in half for the trim pieces which hold the panels in place
- Rather than have the fence open at the bottom, I'll make a panel with 1/2" hardware cloth for the bottom 12" or so, again trimmed/framed with ripped 2x4s on three sides and buried in the ground on the bottom to protect against burrowing creatures.
- Will run 2x6s around both inside and outside of posts around the top to help with overall stability and resisting any twisting of the posts. Will face-nail to the 6x6 posts on the outside and toe-nail into the side of the 6x6s on the inside of the fence.
- Total height will be 8-9' above ground
I feel pretty good about the plan overall, but have a couple of concerns:
- Never used a framing nailer before. Gotta practice to make sure I can keep the top and bottom rails in place when I toe nail them
- Bottom 2x4 rails supporting the weight of the panel. Online calculators tell me deflection shouldn't be an issue over a 64" span with evenly distributed weight, but experience tells me a 2x4 run horizontally like that is going to sag over time. I'm hoping/expecting that the 2x "trim" pieces will help add rigidity to the span and help resist any sagging, but these obviously will be mechanically fastened together rather than being a true 3" thick piece of lumber (does that matter?)
- Will the connection points of the bottom rail to the posts be strong enough?
- Are the 2x6s at the top of the fence too big a sail such that they'll to much force on the structure in high winds? At the least they will make it a little top-heavy. I"m wondering if 2x6s would be better, even though they'd be less rigid
Would love to hear any thoughts/feedback folks might have. I've been pricing out materials the past few days and it looks like it'll come in right around $2500. Yikes!
And after this I have to put together the Costco greenhouse we have on order...
