Having said that, we're in the first stages of establishing our vinyard, so the posts are not even set yet. They have been delivered (and it's a very BIG pile of posts I might add - a little over 400 total), and the schedule says we're installing next week. Originally, the "plan" was to use the space between the braces for an additional vine, but I don't think I'll need the additional space now that I've reconfigured the vineyard layout (popped a fence out another 16 feet).

    Well, if the nursery ever delivers them... We ordered 700 Black Spanish and 700 Blanc Du Bois from Fairhaven Nursery in NE Texas in September. These are the two vines that grow best in our area. The original delivery date was late February or early March, but the weather in NE Texas has been rather harsh this year. As such, the Black Spanish are not ready for delivery yet (should be ready in about two weeks). The Blanc Du Bois are ready now, but since they are shipping the order on their dime they want to do a single delivey.
    You should see my post pile. 2200 of them. Ordered two truckloads last fall for the new vineyards we planted last spring. Going to be fun planting all the posts this spring.

    Good luck with your plants, the first year is the hardest.

    2200! Yikes! Now I know why you have a post pounder! My lumber yard guy about freaked when I ordered the 400 for the vineyard - and that was two weeks after ordering over 130 12 footers for the deer fence. Now, everytime I go by the yard, I drop in and tell him I need more posts - just to see his reaction! And yes - the first year is certainly the hardest. I'm sure I'll make mistakes along the way (already have), but I'm having a blast - and in my book that's all that counts!

    I have 33 active acres of grapes and planted 11 additional acres last spring. I go through a couple hundred posts each year on the 33 acres. It keeps me busy

    3) 50 foot between posts is too far in my opinion - put another post in. I'd also suggest switching from 4x4's to round CCA posts - they are MUCH stonger. You only need a few - so cost shouldn't be an issue. I'm using 5" round 8 foot CCA posts for line posts in our vineyard (which is a bit of overkill). Those are under $10 from my local lumber yard - your price may vary. I'd STRONGLY suggest the end posts on your H Brace be larger. I went with 6" round 10 foot CCA posts for the ends on our vineyard trellis. Only the end posts needed to be set in concrete. I'd also use another of the 5" 8 footers for the cross brace. If you're still stuck on using square posts, then at a minimum skip the idea to use a 2x4 for the cross brace. The cross brace needs to be a 4x4 as well.

    One more thing - concrete for posts (40 lb bags) can be purchased at Home Depot for about $4 a bag. It's the RED bag. Works great. Just dump the contents of the bag in the hole and then add 1/2 to 1 gallon of water. Dries HARD in 4 hours and is ready to use the next day.
    You think the 12.5 ga high-tensile stuff needs more support between?

    The posts we have are radius edged 4x4s and already have them. Hope I don't regret using them in the future, but will be a pain to take back.

    We have 6 50lb bags of sacrete. You think one bag per hole is necessary? I was thinking half a bag incase posts need to be removed for some odd reason. Figured it would be a bit easier.

    I hear ya on the 2x4s end braces. Haven't purchased anything yet for that, so still up in air. How would you connect the 4x4 cross braces? Bolt through sides of posts together or bolt them "in-line" (Hope that makes sense)

    I use mostly treated posts in my vineyards but that is because it is easier for me. I use locust for the end posts though because the locust will outlast the treated 2-1 easily. I don't split the locust trees either, I put them in full size so I am selective in what trees I cut. The biggest posts I can and will use for end posts are 10" diameter but each posts gets smaller as you cut. Downside to locust is it is extremely hard when dry so pounding staples or nails after it is dried can be difficult.

    Don't think there are any locust trees on property

    Yes. If I recall, the maximum length on trellis wire without support is generally considered to be 30 feet. If this was wire for a fence to keep livestock in (or out), then you could go much further. But there is no "weight" being supported in the case of livestock. I think you'll sag in the middle if you go 50 feet. I could be wrong, but a single post is $10 - why take the chance.

    I'd save those for another project and buy the round posts. They are WAY stronger, will resist warping better. If you bought your post at the same place I buy mine - you'd be looking at $50 for 5 of the 5" 8' CCA posts and $30 for two of the 6" 10' CCA posts. That's $80 well spent.

    The Sacrette I used was in 40 lb bags - so we're not comparing apples to apples (or blackberries as the case may be). I personnaly don't like storing concrete as it tends to go hard over time. You've only got two posts that I think need to be in concrete, so I'd use the whole bag. The End posts absolutely need to be in concrete, but the brace post will be fine without. Same for the middle post if you add one. The tension is on the end posts - not the middle post (line post). The brace post is held in place by the brace wire, so it usually doesn't need concrete, but it certainly doesn't hurt to add some.

    How would I connect? I'd use pins, not bolts. The brace wire will hold the End post and the Brace post together - as such it doesn't need to be bolted together. You'll need two 10" brace pins and two 5" pins. You can get these from Tractor Supply in packs of 5. The 5" package is about $4 and the 10" is about $5.

    I've had a change of plans. Not doing the Triple Crown, which would need the most support. Reason for not doing so is I am getting mixed reviews on them fruiting this far south with amount of chill hours. Will probably plant them along edge of property and let them go wild.

    Now, I am doing the erect varieties (I thought they were semi-erect, but supposedly they are erect) that grow straight up first year and only droop when they get weight of berries on them. A "T" (2 wire) trellis is all that is needed and I don't see a problem with my set up. So far, I'm using 3 4x4s concreted about 2.5' deep in a span of 80'. I have 9ga galvanized wire (ordered earlier in year and wasn't going to use it, but since I have it, I will.

    I appreciate all the info. I think most of what y'all were recommending was more suited for grapes (which I plan to do sometime in the future) and the weight they produce. I will keep y'all updated on progress.

    Thanks!

    I will add that I may end up adding some bracing, but I really don't see the need for it for the ~18 erect varieties I have.

    Crossbow spray will kill those blackberrys. Where I'm at in Oregon Blackberrys are taking over everything. Nobody cultivates them!!!!
    In Summer when we see cars pulled to the side of the road picking Blackberrys it will be someone from out of state everytime.
    Whatever you do keep them controlled. Birds will spread the seeds. Soon you will be seeing your neighbors at your door with pitchforks and flaming torches blaming you for the evil you have brought them. The local farm store will be sending you special discounts because of all the new business they are getting from people trying to rid themselves of the blackberrys you brought to the area.
    On the other hand Blackberry Cobbler with ice cream can't be beat. I freeze a couple gallons every year. Enjoy!!!!
