I have anupdate on the vine hardiness and blue-x shelters.
90% Cab Franc loss.
50% Vidal, Traminette, Noiretvine loss due to winter injury.
All the Vignoles & Marquettesmade it.
The west outside row is being replaced with own rooted Concord, Niagara & Frontenac Gris. Considering using Geneva Double Curtain. Hoping it will attenuate the winter winds in the hybrids to the east of them. Filled in lost Noiret & Traminettewith a few Corot Noir & many more Marquettes.
Significantissues causing vine demise: arrested root development & insufficient vine height going into winter; green-house affect of blue-x shields during the winter temp swings. There are certainlyothers I've failed to recognize.
Lessons learned my first year: need balanced fertilization to promote root growth and foliage to get vinesas close to top wire as possible by fall;assure vines do not have to compete with companion grass for nutrients; remove blue-x shields no later than August to harden off the vines;hill dirt over graft union before winter;seed w/ nemotodes this spring to eat jap beetle larvae before they hatch; spray for jap beetles to prevent huge foliar losses; water young vines weekly (weather dependent).
Seems I've made about every mistake a newbie can make
Well, this is another year and I'm definitely NOT a quitter. Many thanks for the posts others are making regarding vineyard management. It has helped me tremendously to read how others are doing things.
I'm a little torn about the GDC system. Rows run North - South. Vine spacing is 10' x 8' for NA's, 10' x 6' in hybrids.Since I'm short in stature, trellis height is a little over 5'. Does anyone feel I'll introduce too much afternoon shade with the GDC going in onthe farthest west row? And, is it even necessary to do GDC with the selected cultivars? Is TWC sufficent? The hybrids will train to VSP. All opnions & advise is welcomed.
