| I just bought five grape vines and eight blackberry plants. I was needing help with the best way to trellis them. Thanks. |

| No best way, depends what you need, want, and have. Spur or cane pruned grapes. Trailing or erect blackberries. I use a 2 wire system at 3 feet and 5 feet. Posts can be installed numerous ways. I like 4x4 with grapes, and 3/4 inch conduit steel for blackberries. 2-4 wire systems can be used. I also like dual wire systems where I can use them, mostly for raspberries. |

| Like Drew51 says, there is a lot of ways to build a trellis. Grapes tend to need a strong trellis to support the weight of their fruit which can sometimes be 30-40lbs per vine. Blackberries, depending on the variety, can sometimes get away with a single wire if you tie each cane to the wire individually. What kind of blackberries (e.g. variety or varieties) did you purchase? |

| If I were you for the Blackberries if you are planting them in a row, I would sink an 8 feet long 4X4 into the ground 2 feet, anchored in cement on each end. Run a 12 gage wire at the 2 foot, 3.5 foot, and 5 foot levels and pull tight. Use 6 foot long metal posts between each plant sunk 1 foot into the ground and tied to each wire. For the grapes I would use a "T" trellis made from 8-foot 4X4 posts and 2X6 cross pieces with 3 12 gage wires connecting the cross pieces, pulled tight. You might need anchors for your end posts to prevent leaning even if you use concrete in the holes, which I did. |

| CharlieBoring, The blackberry trellis you build should reflect the type of blackberry you are growing. If you are growing an erect variety like Prime Ark45 or Oauchita, you really only need a single wire at 5 ft to keep the plants from blowing down in a wind storm. Otherwise, they would be fine without the wire. If you were growing a trailing or semi-trailing variety like Triple crown, then you really need a heavier trellis to support the weight of the plant plus fruit and give the trailing canes something to keep them off the ground. |

| What kind of blackberries? What kind of grapes? What zone are you in? You might take a look at every one of the people who responded and see that next to their name is the agricultural zone they're in. Since you're posting on a gardening site, why don't you show the zone or better still, the zone and what part of the country if it makes a difference? |
