Dave,

Thank you for posting your videos. The information you have presented is gold for amateur backyard viticulturists that don't have easy access to a vineyard. I am impressed by your love of the subject and the time you take to explain things that may be obvious to people in the industry, but are totally foreign to those of us on the outside. Your explanation of the reasons behind the grafting was thrilling. I hope you keep posting similar videos!

Hello Shjanzey,

Very happy to hear you liked the videos. I have found how much I really do enjoy working with these amazing plants. I have lived here in this valley almost 40 years. I wish I would have done this a long time ago.

Thanks again for the message,

Dave

hi Dave,

Thanks for the videos i am going to follow with interest the vine,

here in malta we prune a little earlier to you , we get hot summers and very mild winters, what i wondered is you never mentioned about feeding ?? i was told that at the time of feeding, it was good to give a handful of blood and bone...is this a good thing to do...love to hear your comments, thks steve

Hi Steve,

Thanks very much for watching. Vines certainly need nutrients, but at times it can be difficult to know just what the plant needs. Some farmers will fertilize in a method as you described, but if it were possible a more precise method to determine fertilizer needs is better. You might consider doing a petiole sample during bloom, the nearer to full bloom the better. You would then need to send the samples to a lab which could determine any nutrient deficiencies in the vine

Thanks Dave

is too much nitrogen a bad thing for vines?

also if one planted his grafted vines a little deeper say 2 inches below final soil line...is that a bad thing?

will the scion root if you level out the soil and thus allow phyloxera to enter the roots?

[oneacrewine]

Hello agrotis79

Yes too much nitrogen can be a bad thing. It can cause too much vigor and cause the vine to get out of balance. Too much shoot growth in relation to the crop load. Which could actually cause the sugars and the pH to get out of balance.

Sometimes if the soil is too high, and there are any buds that were not fully removed, the scion could develop roots. That is why it is usually best if on grafted vines the graft union is about one fist above the soil.

Nice vineyard. How many inches do you plant the graft union above the soil line?

How does the 101-14 compare to the other rootstocks like 3309, S04?

any experience working with Ruggeri 140?

I'm trying to find a good rootstock for my planting...I have very light soil. I don't like 3309's vigour it is too low and it is susceptible to nematodes.

[agrotis79]

Thanks for answering....

What rootstock do you predominantly use in California?

Have you ever tried 140 Ruggeri?

what type of soil do you have..loam, clay?

Hello Souvik,

I did a little research and found that the cultivar Pusa Navrang seamed to be the best suited for wine and juice purpose while Pusa Urvashi was considered for table use and Arka Neelamani for both the purposes. It appears that these three varieties are being planted in the Western part of West Bengal.

Were you thinking of planting a wine grape or table grape vineyard ? You might check with some local nurseries and see what cultivars are doing well in your area.

Thanks for watching

hi Dave, I am from West Bengal,eastern part of India,and very much keen to make a vineyard in my region,the summer temperature is around 40-45 degree Centigrade and winter temperature is 10-15 degree centrigrade,annual rain fall around 1340 mm and the soil is red and laterite, porous, low in organic matter and nutrients and pH varies between 4.8 and 6.5. The landscape is undulating and the soil in this area is highly erodible, is it suitable for grape production?please suggest

thanks,

souvik
