It is too late to head the trees back now, plus it is counter productive to head Tall Spindle trees. The whole point of the tall spindle to develop a tall and narrow tree with weak laterals not strong laterals. If you head them back you get strong lateral branches and trees with “scaffold” branches that grow too strongly for the 3 foot inrow spacing of the tall spindle. The lateral branches will naturally fill in over the first few years but with weak lateral branches instead of “scaffolds”. Where trees did not have enough feathers at planting we have had good success with a spray 500-1000 ppm of Maxcel (This is 5-10X the rate used for thinning) at 10-14 days after planting. It works except when excessively cool in the spring. Where there were not enough branches from the nursery or from the Maxcel after planting then we “notch” and paint or spray Maxcel anytime from green tip to pink in year 2.

In our apple orchards in the tropics the endless season would result in whips 12'+ tall if we didn't intervene. I'd cut them back to 5' tall and notch above every bud to encourage lateral branching; this should have been done in April when they just started to push. I'd probably still do this now, though I'm open to hearing from others why you shouldn't.

This year we planted 5000 apple trees tall spindle style. These will be used for upick. The nursery I bought from gave me about a thousand terrible trees with almost no feathers. I have sprayed heavily with Maxell to encourage lateral bud growth. Has not work that well. My Orchard is located right next to one of the Chicagolands largest commercial tree nurseries. The field manager of the nursery recently stopped by and told me he would encourage lateral growth by heading all of these poorly feathered trees. I know the rule with tall spindle is generally you never had the tree, but I think the assumption is that you have a lot of feathers. Has anyone ever headed poorly feather trees to encourage lateral growth? What were your results? _______________________________________________ apple-crop mailing list email@example.com<mailto:firstname.lastname@example.org> http://virtualorchard.com/mailman/listinfo/apple-crop
