Hi Art; Are you talking about total length of a row, or length between support posts?

Re: [apple-crop] Tall spindle trellis
We had rows 2200 feet long between end anchors. 4 wires, 10' high with posts spaced at 42', 3' deep. End posts were a larger diameter, 4' deep at about a 45° angle. Wires and anchors were attached to a 4' long screw in steel anchor with 8 plate. Ground was basically flat. No problems holding a bumper crop.

[apple-crop] Peach question
I had a guy ask a question yesterday for which I didn't have a good answer. He had purchased peaches from another orchard and complained the peaches had mold next to the pit. What he described was a white substance next to the pit, not unusual in freestone peaches. At one time I read an article which described in specifics what the white substance was, but I can't remember now. I told him it probably wasn't mold, and that it was natural. I'd like to have a more specific response for my own customers. Anyone know what the white spots are next to the pit, sometimes seen when breaking open a freestone peach?

Re: [apple-crop] Peach question
From what I have experienced, Mark, sounds like you are talking about callus tissue that can appear around the pit. The tissue is not mold, fungus, bacteria or the result of any type of disease. It is naturally occurring as you say, and is entirely safe to eat along with the rest of the peaches that they appear in. But, there are times when peaches that have split pits will mold on the inside because air is available to the inside of the peach. Split pits are usually caused by too much rain. A little molding around split pit fruit is usually okay. The difference between callus tissue and split pit mold is that the mold generally occurs in conjunction with the split pit and is actually mold. I understand that the mold is harmless as well.

Re: [apple-crop] Tall spindle trellis
I agree with your assumptions, Dave. We have over 200 rows of trees, about 1/3 being tall spindle. We build out trellises with 12' posts, typically 8 thick posts (6 on shorter rows of 400' or less) leaving 4 feet in the ground.and 8 above with our top trellis wire being on top of the post at 8'. We keep our trees at 8 to 8.5', mostly m9 and m26 rootstock If we leave the posts at 3' depths, frost heave (Illinois/Wisconsin border) will move them out of the ground a few inches each year, even with cross-anchors on the base. We also loosen the tension on the wires, 4 on tall spindle , 2 or 3 on the central leader depending on rootstock, central leader being mostly M7. Our rows run from 300' to 900' and we space the center posts at 50' intervals. We have found that loosening those wires in the late fall after harvest but before the first frost keeps the posts from moving when frost goes deeper than 4'as it has this winter. If we don't get those wires tightened back up before the growing season starts, the tall spindle trees will start leaning and those end posts will go with them from our prevailing winds. When attaching the wire to center posts, we allow them to slide through the staple, which eventually puts more of the stress on the end post, but we also adjust the tension throughout the growing season. Since we are also a U-Pick operation, we have to be concerned with safety, so we do not use wire stabilizers at the ends of the row to brace the end post. We brace the end of row post with a 6' post angled back into the row as pictured at http://fruit-crops.com/wp-content/uploads/2012/11/3.10-slender-spinle-apple-bolzano.jpg with another post 4' in the ground at the base of the angle post 1' above ground for additional bracing. If we don't get the brace at least 6' long, our posts will start to lean into the row. This system seems to have worked well for us over the years with minimal maintenance from leaning posts. We have found the publication Support Systems for High Density Orchards at http://www.al.gov.bc.ca/resmgmt/publist/300Series/336000-1.pdf to be quite helpful. And, fortunately for us, we were a family of residential home builders prior to getting into the orchard business and my father in law has an engineering degree!!

Consider the worst case scenario: Trees that have grown to 3-ft above the wire (i.e., 13 ft tall) with 2000 bushels/A evenly distributed over the upper 12 ft of the canopy (i.e., none within 1 ft of the ground). That could mean that 25% of the fruit are above the 10-ft top wire, and in my experience those upper limbs will tend to fall toward the leeward side of the tree due to wind effects. Let’s assume that trees are on 10-ft row spacings and that 10% of the total crop is above the wire and off-center to the leeward side. If I’ve done the math correctly so far, that means that every acre will have 4-tons of apples off-center and at least 10-ft above ground. At 10-ft between rows, it will require 4,356 ft to make an acre. Thus, with rows 1000-ft long, there will be roughly 1 ton of off-center apples 10-ft above the ground. Now add a 40 mph crosswind just before harvest, and (for those in the east) assume that you just had 10 inches of rain due to a hurricane coming up the coast. The line posts will provide some support, but ultimately the greatest stress will be on the end-posts, and that stress will increase with the total length of the trellis. Even on short rows of only 300 ft, I have gradually seen trellises go off-center with time (i.e., line posts begin to lean a bit) due to wind effects, uneven cropping on the two sides of the trees, and slope (which leads to uneven frost-heave effects). If the trellises are tilted just a bit under the scenarios outlined above, then the stresses on the end posts will be multiplied. Admittedly, my observations are mostly with wider trees and wider row spacings, and those planting systems probably was more prone to going off-center than a narrow tree wall. Nevertheless, the side-ways forces on trellises should not be ignored. You may quibble with some of my assumptions, but I really would like to see/hear an engineers perspective on how long rows can be given various soil types, diameter of both line
Re: [apple-crop] Tall spindle trellis
We have rows over 1100 feet long but installed an 'H' brace at about 400' - 500' to add stability.

Re: [apple-crop] Tall spindle trellis
I have experienced what happens when rows go down and it isnt fun. Most trees snap off at the graft union. And they take their neighbour with them for a couple of hundred feet up the row. By this time of course you have all of your annual costs into them but the harvest cost. Its a real mess. That same block has other rows that lean and have to be propped every year. Thought I had got away from that years ago. Bringing rows back to the upright is nigh on impossible without snapping more unions. We are now placing in-line posts at 32 ft. The trick I think is not to let trees get top-heavy.
