I am in the 8th year of 3 year staggered planting growth of a Tall Spindle Apple Orchard. The Planted Area is about 2.5 acres containing 1750 trees. As a first time grower in a VERY windy/blustery location, I did not want to deal with movement or collapse. Hence I chose 14ft long treated Yellow southern Pine 5-6 Posts driven 4 feet into the ground by a hydraulic ram. We were very careful to keep the rows stright and posts Plumb. Posts are spaced to allow 10 trees between them @ 3 ft spacing per tree. This left 10 feet of post to support 4 wires each helping the trees to withstand wind pressure.
The end supports for each row are pinned @ about 8ft to anchor posts driven 4 ft into the ground & secured with guide wires @ 45 degree angles. This created an equalateral triangle at each end offering very strong, stable support. The wire is high tensile 12 guage fence wire. All wires have been tightened by hand with a wire stretcher, using grepples and two leaded crimps on each tail. There has been little change in the wire tightness ie slack. In 2015 we produced 55,000lbs of apples in a not yet mature Orchard. We are striving for about 400 more bushels or 56 to 57,000 pounds as a max. That's a good amount of support from this design.
