I ordered a few different variety of vines Saturday. Cayuga White, Marquis. Their suggested training system is Mid wire cordon, and the mod. Munson. All the other vines I ordered use the top wire cordon. My question is, do I have to use what is suggested or could I use the top wire cordon for all of them? If I did use the TWC for the Cayuga White, and the Marquis, would there be any Ill affect? Thanks for the reply's.
