I am letting others help you with this as I haven't had enough time to fully address it but I will say that like balatonwine has said, drainage will limit you. It won't do any good to have a top notch training system if the drainage limits vine growth. Grapes have pretty deep spreading roots...
Looking good Mike. Things grow much better when it is warm and sunny than snowing. LOL
It was 90 here yesterday and 92 this afternoon and will be 30 degrees colder for a high tomorrow. Do you have whiplash as badly as I do?
Sounds like you are right on track. You sprayed for PM and then got rain, but prevented PM infection likely because you had sprayed. If more than inch and a half of rain spray again. You applied miracle grow and got rain so the miracle grow got worked in.
As for the second crop of clusters they are- well a secondary crop of clusters. Vines can grow longer than desired for the canopy of the training system used and are then hedged or skirted (hedge at the top like VSP vines or skirted at the bottom as in Tor or High wire cordon). If done before...
Since you are from Russia you may have a challenge getting vines over there, not because it is Russia but because it involves moving plant material around the world. Things involving plants and animals aren't as straight forward as letting people go from country to country. Countries other than...
Sorry for your loss. Salcoco is spot on about more buds. Hopefully you didn't have too many secondary buds push yet but it didn't look like they had in the first picture. This is one of the major problems with Marquette. It breaks bud early and grows and is very susceptible to late freezes...
Petite Pearl has not been growing a "very long time". It has not been released for over 5 or 6 years. As Greg said you will need to find some legal source of vines as it is a protected variety. He is a private plant breeder and deserves to get paid the small royalties he gets.
You need to take into account the average weight of the clusters of the variety grape you are working with. Obviously if you grow a large sized cluster say 3/4 pound to a pound apiece you would want to limit the shoots more or you would overload the vine. Marquette however has small quarter...
First picture Keep A & B. C is a secondary so can be removed after danger of frost. D is a basal bud and should be left this year (will not have grapes on it) to provide the spur for next year by cutting off the old spur above D.
The second picture get rid of the secondary (smaller bud) on...
And I got this from a Mr. Woo Park this morning:
Sir,
Total Remittance: US $ 61,704.97 for our last order, Kindly advice date of shipment.
Regards,
Purchase and Logistics.
Not as large as yours but I get a number of these every week so they add up!
You really need to know what is deficient or in too high of an amount before applying foliar. I assume the GA is Gibberellic Acid. That may have some bearing on the grape size since it is used to size up grapes. Maybe it was the wrong dilution rate? I really have no experience with it.
It is almost like there are two strains of Petite Pearl out there. I first planted Petite Pearl 6 or 7 years ago. When I received them they were in the little white paper bands. They were so small and it was so late (July) that I put them in a nursery I grow vine starts in. They just did not...
I wish I had a quick answer for you. The yellowing vines look like a nutrient deficiency which can also cause shriveled grapes like those. If I had to guess I might say Magnesium or Iron. A leaf petiole sample might narrow it down for you. Also if you could get a foliar fertilizer once the...
Remove any double shoots at a node (keep primary and get rid of secondary shoot). Marquette will handle two clusters per shoot even at 4 years because they are fairly small. If shoot vigor gets too weak a bit later in the season drop one then. If you don't keep a fairly good load on the vine the...
Double A Vineyard near Buffalo will fix you right up as long as they haven't run out yet. They will sell any amount you need but there is a pretty good price break at 25 and even better at 50. That is for the whole order so yours would fit the 25.
We are having some chilly weather here for the next few days with low 30's overnight. Thankfully most of the buds are still tight although some are trying to make a break for it and open up with some buds at about 3/4 inch. The lows will help slow the growth down and hopefully we can get past...
Great job helping her out like that. It will be nice having her close but not across the street. Close enough to get the food to share (and company) but not so close she can tell what time you got in or got up.
