Dimensions tall fence for large vegetable garden 8 x 15 m

Solrosen · 5 Apr 2021 at 10:18 PM

Hello!
Time for this year's outdoor project. The old potato patch will become a 144 sqm cultivation garden in 2022.

Approx. 2000 mm high fence with reinforcement mesh as walls. cc 2500 between the posts/spars. Have dismantled a couple of fences in my building history, but none over 800 mm or longer than 10 meters.
Since the fence walls (with reinforcement mesh and no plants against the outer walls) have minimal wind resistance, I'm leaning towards dimension 95x95, but have also seen 125x125 rough at my C24 store.
The reinforcement mesh will be "clamped" between the spars, along with a simple topper as protection against sharp mesh ends. There will be 21 in total.

The question is if anyone has built a taller, longer, or sturdier fence?
In my case: Will it be overkill/unnecessary with 125x125, or will 95x95 work excellently?
Prefer to avoid low-standing 45-degree support in the middle of the long side or braces at the top in the corners but might be a good idea for extra stability?
Inputs?

Details I see as critical include orienting the U-post shoes correctly (minimizing sway) and ensuring that the cast posts are stable (depth and reinforcement).

The enclosed garden will be a rectangle of 8 x 15 m.

I'm thinking of a similar project this summer, how did it go?

Yes, it's moving forward

Damn, that's stylish! What are the measurements of the posts? Any other good advice?

Solrosen · 5 Apr 2022 at 9:57 PM

Paper tubes, weber all-round concrete, beam shoe, masonry line, level, patience, concrete mixer, muscle power.

Posts 95x95

A friend has insisted that it doesn't need to be cast, that post spikes are enough, but when I see your construction, it feels considerably more stable. The reinforcing nets do weigh a bit. Mine is probably about a meter shorter on each side, but this looks very impressive.

I must say that I wasn't completely impressed with the stability of the stolpspjut/jordankare I've seen.

Maybe it depends on the type of soil? In any case, I will continue digging and casting...

At such a height, post iron is more stable but based on the assumption that climbing plants will eventually grow on the net. Without climbing plants, it is likely stable enough.

Yep, I have tried post spikes in another fence project but wasn't impressed. I found them difficult to get straight, and if there's rock in the ground it gets even worse.

Hi,

Nice fence and lots of good info! I have a few questions:
How deep did you cast the foundations for the posts? What size reinforcement mesh did you use?

Hi,
Dug down about 50 cm deep. In some places, it was only 20-30 cm due to boulders.. dug wider than the pipe and cast a wide base at the bottom about 15 cm thick as a foundation. Put the pipe in the middle and filled it up.
Pipes: 190mm

Mesh: 6-150 or it might be written in the other order. 6 mm diameter, 150x150 mm holes

Started building the planting boxes. Various heights and sizes using leftover wood from the yard. Filled with last year’s cow manure from the neighbor, but first they were lined with construction plastic and a layer of 50cm logs at the bottom for the benefit of small insects. Black sleeper oil for appearance's sake

Right now, more planting boxes are being built in our cultivation project. We hadn't really considered how much work it would be to build these - and it turned out to be the heavy part of the entire project haha.

So by spring, we hopefully have more empty boxes to place out. Pre-built in one of the utility buildings.

Cultivation-wise, we managed strawberries, "sugar snaps," and corn, as well as a year's supply of various herbs that we've frozen.

Time for an update. The cultivation garden is progressing. More boxes have been built during the winter, and we also got a greenhouse a week ago. The frame got 6 cast pillars which took some time, but otherwise the assembly went smoothly.

Neighbor-cow manure is coming this week to the manure platform, for some mixing with the mini-excavator before filling the boxes.

This year it will be strawberries, cucumbers, radishes, raspberries, tomatoes, peas, physalis, chili, dill, lettuce... and elsewhere blackberries, rhubarb, gooseberries, black currants.
We're trying a bit of everything to see what works and what doesn't.

Really nice! This is exactly something like this we are planning for the summer.

What kind of slats are holding the nets in place? If the posts are 95x95, I guess they are significantly smaller than 45x45?

Thanks in advance.
