Here is my plan, It needs advice and critiqueing.

I have 25 bud 9 rootstocks in the mail comming to me. I plan on planting two rows. 13 and 12 to a row with 15' spacing btw rows and 8' spacing btw trees. I looked into using 1" electrical conduit but I think I will use 2x4x10 treated at each tree. Next year I can drill all the 2x4's and run #9 wire through them for the length of the row.I plan on planting the bud 9 as soon as they arrive and chip budding in August. I have a couple of issues I need help with on chip budding.

-First I dont know what a propper bud looks like.

-Second I really want some scions to bud from Wolf River, Williams Pride, Freedom, Zestar and Liberty. I have a few trees here at home I can use-Honey crisp, Regent and Cortland. I just am really interested in the ones I mentioned. I could use some help to find someone with those trees.

-Third can I plant any closer btw trees?
