Last planting of the season

Today, we awoke to brilliant sunshine and, hopefully, one of the last times we will be changing the clocks. So, we grabbed the remaining Albarino vines, some shovels, gloves, and knee pads, and headed into the vineyard to plant them. The buds were growing and it was time. Alex had pre-dug the holes. He distributed the vines as I got to work.

Brilliant day

3-y-o Solaris vine

We are experiencing an amazing weather week. No rain, light winds, and, today, brilliant sunshine. It was glorious. I walked up into the vineyard to check on progress as the plum and cherry trees are in full bloom already.  Lo and behold, although the 5-year-old vines had not yet leafed, the first leaves were unfurling on the three-year-old specimens. Interesting.

Pollinators and grapes

The headlines last month were dire. "Plummeting insect numbers 'threaten collapse of nature'" warned The Guardian. "The rate of insect extinction is eight times faster than that of mammals, birds, and reptiles." That is such a definitive and frightening statement. 

The analysis of 73 historical reports, published in the journal Biological Conservation, concludes that intensive agriculture is the main driver of the declines, particularly the heavy use of pesticides.  They provide a few highlights of the exhaustive analysis:

Highlights

• Over 40% of insect species are threatened with extinction.
• Lepidoptera, Hymenoptera and dung beetles (Coleoptera) are the taxa most affected.
• Four aquatic taxa are imperiled and have already lost a large proportion of species.
• Habitat loss by conversion to intensive agriculture is the main driver of the declines.
• Agro-chemical pollutants, invasive species and climate change are additional causes.

Spring is trying, then retreating

Several weeks ago it was warm enough to be out in T-shirts. Alex noted that the new chardonnay vines were sprouting and quickly planted them out in the field. Then he planted out the Pinot vines. There is still a batch of Albarino bare root vines that are heeled in to plant and trellises to build. But he was off buying cattle for his mother today so it will have to wait. Tomorrow, we're doing a webinar about sailing in Galicia, so it will have to wait again. Oh well, we have a few days open next week I think.

The bumblebees were out in force, feeding on the heather during the good weather. I counted 13 queens on one bush one day, mostly Bombus leucorum. It was good to hear their buzzing in the garden. The heather bush was the first thing I had planted when we were building the house. So glad I did. But I was also glad to learn that grapevines are not dependent on bees for pollination. The news about the collapse of the insect populations last week was alarming. More about that another day.

Cover crops and companion plants

My last post dealt with underground fungi that form symbiotic relationships with grapevines. Today, I'm investigating cover crops and companion plants that can be grown with the vines to help promote healthy soil structure and nutrient exchange and perhaps even protect against insects and disease. Cover crops have been used for millennia and are becoming more popular again with the advent of organic farming and the desire to reduce the use of pesticides and herbicides.

Grapevines in partnership with fungi

I've been reading a fascinating book called Mycophilia by food writer and cookbook author Eugenia Bone. She stoked my interest in everything mushroom. I have been most interested in the symbiotic relationship between underground mycorrhizal fungi and photosynthetic plants above ground. Some fungi serve to remove and clean-up diseased and dying plants. Others have symbiotic relationships with specific plants they tend to. Their root systems get intertwined, the plants delivering sugars to the fungi, the fungi extracting minerals from the soil and delivering them to the roots of plants.

New vines have arrived

The new vines have arrived for phase 3 of our planting. The first year there were ten, the second year there were 65. Now we are adding another 66 vines. Of those, 25 are Pinot Noir and 25 Albariño, and 16 Chardonnay, all on SO4 rootstocks.. How we're going to manage them is another discussion.

Of course, while in Alexandria for three weeks, I learned that Viognier vines are commonly planted in Virginia. Viognier — the state grape of Virginia — is a wine made by 76 of the commonwealth’s 230 vineyards as of 2012. In May 2011, the Virginia Wine Board approved the marketing of Viognier as “Virginia’s signature grape,” just as Cabernet Sauvignon is identified with California’s Napa Valley and Pinot Noir with Oregon.

Viogner, that rare French wine that we discovered in St. Martin and brought home cases of it on our boat. In the mid-1960s, a mere 3.2 acres of vines existed in the entire world. It does extremely well in Virginia and is considered quite possibly the best Viognier made outside of Condrieu — home to the Viognier grape in the white-wine capital of the Rhône valley. Alas, as Viognier vines start to hit their peak after 20 years, I don't think we'll be planting many here in Ireland but if Virginia's young vines (mostly <10 years old) are doing so well, you never know. Stick with what you like, right? And we do like Viognier.
