Budbreak

The growing season is here. Sprays have commenced. No pest trouble :) yet...

Budbreak was seen in greater than 50% of petit manseng on April 14, and less than 50% of petit verdot that same date.

Frost visited our vineyard April 22. The low temperature reached 31 degrees. There was very mild damage in the petit manseng, but enough to show that old man winter can still make an appearance. New growth is very sensitive to frost, and harvest can be drastically reduced by a frost event.

Early spring means bleeding

Pruning cuts often leak sap in early spring, often called "bleeding" or "crying." But no one around here is crying. We are ready for budbreak!

2013 season: Gearing up

Well, nothing has been posted for a while. The deer, for a second season, enjoyed the 2012 harvest. The barriers used were ineffective. Fencing has been purchased, and will be established soon. Lessons have been learned: control the varmints! (and fungus and insects).
I am thankful for the lessons of 2012. The spray program was effective. We obtained grapes from Mount Juliet Vineyards, Silver Creek Orchards, and Horton Vineyards. We made cabernet franc, merlot, malbec, and mourvedre. Winegrowing and winemaking education will continue to press onward...

The vines continue to sleep under a blanket of winter snow.

Speaking of education and experimentation, the petit verdot and petit manseng, on alternate rows, are pruned to spur or cane. I look forward to seeing how these vines perform differently. I especially anticipate differences in shoot thinning, with cane-pruned vines requiring less labor. The question will be whether the difference of less summer labor will outweigh the spring labor of retying of the vines to the training wire. The fruits (literal) of my labor will also be compared.

Recap from a post-derecho vineyard

So far, 2012 has offered a very cordial growing season. Any shortcomings experienced in our vineyard have been attributed to learning experiences. One day in June, we felt forced to spray before an imminent storm. However, temperatures spiked in advance of the rain event, and burned leaves and even some fruit. Lesson learned.

We have learned meteorology as well. On June 29, we experienced an amazing straight-line wind storm, called a derecho. The leaves were thrashed by winds and flying brush. However, the fruit held strong. On the contrary, our orchard lost almost all the apples and pears. The vineyard was spared mostly, but a few scars remain.

Veraison will be any day now...

2011 plantings. Growing very well.

Fruit set & leaf pulling. Memorial day.

A healthy vineyard. The 2009 planting on the right, 2011 planting on the left. The 2011 vines are thriving, with no visible deer nibbling this year. Deer severely impacted the vineyard last year, but not at all now.

Integrated pest management is critical in cultivating outstanding wine grapes. I use fairly innocuous chemicals (copper, sulfur, phosphorous acid, and others), so the cultural practices are even more important. Leaf pulling on the east side allows the morning sun to dry the dew off the young grapes. Less moisture, less disease. Also, it is easier to catch disease earlier with direct visualization of the developing fruit. I just never would have foreseen that I would be pulling leaves as early as Memorial Day!

Safety, shoots, & blooms

Safety third had been my catch phrase. But, eventually, I had to ponder the dangers associated with operating a vineyard. Tractors. Pesticides. PTO-driven equipment. As Mike Rowe says in his video blog, no one else is going to look out for my safety.

I visited Dick Button at Ivy Creek Vineyards to learn about vineyard safety. He discussed pesticide storage, safety during mixing/spraying/cleaning, tractor roll bars, tractor air filtration, PTO shaft clearance, and many other safety issues. He gave me a very nice pair of safety gloves, to ensure I knew what I needed in pesticide handling. This well-spent afternoon may help me live a bit longer & healthier.

Dick recommended that I pursue Pesticide certification through Virginia Cooperative Extension. One Extension visit and several emails & phone calls later, I was on track. There is a core curriculum available through Virginia Tech, and free testing is performed at DMV (everyone loves to go to DMV!). The certification process stresses personal safety, environmental safety, and appropriate use of pesticides. We will continue to use sustainable viticultural practices, following an integrated pest management system.

Reynard Florence Vineyard is a new local vineyard and winery. Their tasting room opened a few weeks ago. I dropped by last week, and met Roe Allison in his vineyard. Roe asked me if I wanted a tasting. I said that I want to help him in his vineyard for a while. After he realized that he wasn't dreaming, we shoot-thinned rows of merlot. What a cool experience! First of all, I operate VSP compared to his Smart-Dyson. Completely different! While I try to have 3-4 shoots per foot, his bidirectional growth requires much denser growth around the cordons. We talked vines, wines, and life. After a bit of work, we sampled his wines. I particularly was impressed with his 2011 100% grenache, sampled from the barrel. He will likely blend it, but it was splendid (some bing cherry goodness). 


And yes, our vineyard keeps growing. We just had 2 inches of rain in the last two days. Nonetheless, the spray program is holding up well. As you can see, several of the vines have already reached the top wire. Shoot thinning is a constant, vigilant pursuit. Cluster thinning will ensue after fruit set. So far, so good.


And no deer problems! Not a single shoot eaten by deer. The milorganite bags are making a tremendous difference this year.

Ready or not, bloom is here. Intensive surveillance and spraying is critical right now. The Petit manseng is blooming, with Petit verdot close behind. Hopefully, a great fruit set will commence.

Growing, growing.

A little water, and the vines are going crazy. I had to hand water once, and rain followed the next week. I have thinned shoots twice. Shoot thinning helps direct growth and limit vigor. The cultural practices and spray program are keeping the vineyard pristine. Contrast the vineyard with a couple distant Concord grapes (black rot spots) and orchard (some cedar apple rust), and you can see the benefit of proper maintenance.
