Although the third method looks appropriated, it is quite important (obligatory) to clarify that pressure treated lumber must be ground contact approved, it means the ACQ, CA-B, CA-C preservative should has the right retention level otherwise the lumber woul rot quickly.

@sam56094 2 года назад

Thank you sir you explained this better than everyone

@jdrichardson1892 3 года назад

Really helped me make my decision on anchoring my posts in the ground. Doesn't seem like anyone else uses this method though.

@OneOfTenVirgins 4 года назад

I was told that the rot comes from the bacteria in the soil touching the wood posts. My last project I took the peel and seal aluminum back for roofs, and wrapped the area of the post where the soil would most likely touch. It's been about 6 years and haven't had a problem. I'm about to expand on the same project doing the same thing in the ground no concrete.

@bartosullivan8050 2 месяца назад

I've had 6 x 6 ground contact pressure treated posts completly fail from rot in eight short years. I now put my posts on concrete pillars above grade usually with heavy guage powder coated brackets. The quality of most of today's lumber is definitely not what it used to be. It's expensive, but there are so many other alternatives like Ipe or Angelique that are so dense they will not rot and are impervious to insects.

@snobud86 4 месяца назад

I knew this looked familiar! Yes that 3rd style of placing the post directly in the ground… I saw it in an engineering of post hole setting for fences! Except you still need to use 4-6” of drainage gravel tamped inside the hole and drainage rock needs to come up a few inches around the base of the post and then dirt goes back in the hole and everything gets tamped down bit by bit.

@YalisCommunity 2 года назад

This is just what I needed. Thank you for sharing!

@larrygh1563 5 лет назад

For well drained soil, I believe in the dirt works fine. For the sorry clay that I have, and the lack of elevation (30' above sea level) I am not so sure. If I can keep the soil dry, then it would sure be alot cheaper to use this method rather than metal reinforced concrete and galvanized steel moment base supports - easily $200 per hole. Longer post needed to put in soil is probably much cheaper than $200 extra. Another concern though is hurricane rating that I want for our gulf coastal area. Maybe drilling through the wood sideways and inserting some some all thread or just rebar to protrude out of the post into the dirt would suffice. A few things to think about.

@m.jackson0846 4 месяца назад

Finally found something informative. I am surprised that the third one is the best. I thought it would be the worst.

@achoo4595 4 года назад

Simple and informative, thank you.

@HyperactiveNeuron 4 года назад

That's very interesting. Like others I've been researching this subject. I'm looking to build a simple pergola type structure for a native species wisteria for my mom. This us actually the first how-to I've read/watched that promotes post-in-ground without concrete. Luckily the frost line here is only 2 feet but our storm season (practically half the year) can be severe. I was already on the fence HAHA about the whole thing... Now even more so. I may talk to some local builders and see what they recommend. I just don't want to build her something and have a thunderstorm treat it up or the frost which didn't even get down to a single foot this past winter push it up and make it look all wonky.

@chrislc35 5 лет назад

What about pressure treated wood leaching into the soil? In California you aren't allowed to throw pressure treated wood into the trash rather it's considered hazardous waste.

@henryt2830 4 года назад

Thank you for this, you're the first one suggesting going back to the "old" way of in-ground post and no cement! You mentioned this works well with pressure treated (no rot). If I were to use Cedar post, would you still recommend this method?

@Gardenfundamentals1 4 года назад

I have not used cedar, but i don't see why not. I even use it for un-treated spruce.

@mmark300 3 года назад

Our cedar fence was installed in concrete. After a couple years my wife put in a garden and the dirt was a few inches above the concrete. After another few years one post broke from the rot and all the others rotting also. So I don't see cedar working with this method for long.

@danielqian8899 3 года назад

@@mmark300That's no surprise for what you experienced. Cedar needs to be protected by applying wood preservatives. Based on my research the following are the three best in the market - Copper-Green’s Wood Preservative (coppergreen.com), Tenino copper naphthenate (coppercare.com), and Woodlife Coppercoat (rustoleum.com)

@christinesforza8600 3 года назад

I inherited a really nice, heavy-duty plastic arbor and I would like to set it in a stable way. I like your video very much and I subscribed because you are a good teacher. Since the legs of this heavy arbor are hollow, I tried inserting the anchor pieces, which are about 8 inches long and have a point, into the ground, but I found I could not do this and set it plumb and level over the anchors, and it did wobble too much for me to feel it was safe in the breezy location I chose for it. What would you think of setting 4 posts of pressure-treated lumber into the ground as you suggest, and slipping the hollow legs of the arbor over these pieces and then screwing them into place. I do not need to worry too much then about rot and since the arbor is not made of wood, ground contact should not be an issue. I think the hardest part of this method is getting accurate measurements for leg spacing, and avoiding a twisted appearance, since this heavy arbor is fully assembled and cannot be dismantled. Any advice would be appreciated. Thank you for a great video.

@Gardenfundamentals1 3 года назад

Attach the wooden posts first. Then dig the holes and place the arbor correctly. Then fill the holes. I do this in this video for a wooden arbor. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wBhe-h3SooQ.html

@brianhackett9649 2 года назад

I just had to demo an arbor that was about to fall over after ten years. I used the post-in-the-ground method, but with untreated HD pine 2x4s. Lay off me, it was my first ever woodworking project! ;) I'm happy to know that i won't have to mess with concrete when i rebuild it, but i want to avoid using pressure treated lumber because of how it will interact with my tools. Is there something i can dip the submerged portions of the posts in to treat it myself? *** As i was typing this, i think i just came up with a solution. Only use PT lumber for the four posts! I won't be doing any tooling on it except for drilling and possibly hand-chiseling. However, i'm worried about the color difference if i stain it. Do you think it will be negligible? Or should i plan on painting it? I'm loathe to paint my fine woodworking projects, but i think i'd be okay with painting an arbor. It may also aide in weatherproofing. Thoughts?

@offleashadentures Год назад

You left out my favorite option. Setting the post a Depo with only Pea gravel. No concrete required. This is been done in New England for hundreds of years - and fences and pergolas don’t move. The only way to move them is to llift straight out.

@richiesun9676 4 года назад

Is there a pergola build video follow up?

@Gardenfundamentals1 4 года назад

Not yet - too many topics to get done.

@georgematos9380 4 года назад

Can you offer your opinion on using "quarter down" gravel instead of dirt around the posts? Thank you.

@Gardenfundamentals1 4 года назад

I have not done that - but i would worry about the gravel moving.

@yuliyabrown5231 4 года назад

I love the idea. Any concern about ground settling over the years and making this structure uneven?

@Gardenfundamentals1 4 года назад

That can happen with any method, including concrete posts.

@kelvinjohnson6059 2 года назад

Thanks for this info!! So I want to build a pergola but the soil in my backyard stays damp all the time. Which method do you think would work best?

@Gardenfundamentals1 2 года назад

The concrete posts certainly won't rot. I used cedar posts for a dock in my pond and after 10+ years there is no sign of rot.

@kennethsarita 2 года назад

thank you for this, I agree with the third method and will try it, if you don't mind, can you share your opinion if using a six 4x4 post for a pergola 19x11 ft is a going to be ok?

@Gardenfundamentals1 2 года назад

Should be fine - it is not holding up much weight.

@scottdillon1 4 года назад

Great video. Based on the photos you have included, you are a skilled craftsman :-) Nice work. I am investigating the best way to attach a free standing pergola (Toja Pergola Systems) to the ground. Because it's a free standing structure, I was thinking of using a concrete post beneath the pavers that I would drill into and basic it's not supporting the lateral movement of the post was thinking about a 2-3 foot concrete footing...any thoughts?

@Gardenfundamentals1 4 года назад

That should work.

@jamieparker3317 3 года назад

Did this work out for you? I'm looking at using Toja as well. (Although, I'd be going straight into the ground - not pavers.)

@scottdillon1 3 года назад

@@jamieparker3317 Hi Jamie, yes...project was completed last summer. I'm hoping to post a video in the coming weeks on the project. In summary, I used about 3.5 feet of sono tube and at the top I created a square top that was framed using 6x6 and I placed that above the sonotube and reinforced it with 2-3 pieces of rebar in each one. The reason for the square top is it gave me a little bit more wiggle room when drilling into it from the brackets which are quite big for the 6x6 posts. So for my siutation, I installed 6 sonotubes 1 at each corner and 2 for the middle supports. For each of the posts, I used 6 inch lag bolts and used 2 lag bolts for each bracket. The structure is not going anywhere :-) Hope that helps but reach out again if you have questions.

@timfoster5043 2 года назад

Was the wood GC-rated? Not all pressure-treated wood is rated for Ground Contact. At Home Depot, the different qualities of treatment will result in a modest price difference.

@Gardenfundamentals1 2 года назад

Good quality wood should last that long. Cheap stuff won't.

@moonpiespotlight4759 2 года назад

I am demolishing a 27 year old cedar picket fence. The posts are still basically good. These though are set in concrete and where I have cut off the 4x4 even with the concrete, the wood is fresh and not rotted internally. Again, this is likely very climate and slope dependent. I don't have a lot of water sitting on my property, and being in central Texas, the climate isn't conducive to water based rot other than rare months where it could begin to occur.
