Vineyard Triage

Hedged Vines

Can good wine be made from hedged vines that have 6 only leaves per cluster in midsummer? Can a cocktail of Rubigan and organic JMS Stylet Oil be applied to combat and eradicate existing mildew on grapes?

Make no mistake. This vineyard is loved. But there comes a time in a man's life when it's difficult to walk up and down that hill, when it's difficult to raise those clippers, when it's difficult to lift that 5-gallon carboy and when it's time to say enough. It was a good run and it's time to pass the baton.

Half the vineyard is a jungle providing shelter for mountain lions, bears and you can imagine the rest. But the other half was hacked, macheted and hedged into submission. "I like to look at it," says the owner about those neat, cleanly shaved rows. The Queen often says the same, "I just want a vineyard to look at," she says, singing a song about how all I ever talk about is temperature and the mildew index. There has been a good grape set (the owner did manage to prune the rows during Winter), but there are only 6 or so leaves per cluster, instead of the usual 12 - 15 after the rows were given a crew cut.

Beware the Prayer of Jabez, the one that goes "Lord, please increase my land, please multiply my blessings." Be careful what you wish for. I will grab that baton. I will step up. I will take care of this vineyard for you. Behold, my land has been increased.

The clusters of Petit Verdot and Malbec are plentiful, but the vineyard has not been sprayed all year and powdery mildew, something I know much to much about, is in evidence. Since we have Rubigan left (in abundance), I'm thinking a good shot of Rubigan will offer mildew protection for up to 3 weeks, so that one spraying may get us through the season. And, Stylet Oil is said to be an eradicant for mildew.  Can they be combined for one spraying?

Very Neat Rows - Eye Pleasing

I adore this vineyard. It is scenic and the vines, now in their 13th year, are mature and have produced subtle, delicious nectar. We have spilled sweat and blood over this vineyard and Bluey, the Australian Shepherd, cellar master of our winery and our muse, overindulged on grapes from these same vines and somehow survived to tell about it. And the wine, that floral Petit Verdot that inspires scentologists to replicate its fragrance, this is worth the effort.

The vineyard was "dry farmed" last year, meaning no irrigation was used in summer, and plans are to continue the same this year.  With the winter rains we had, and based on last year's results, I don't believe irrigation will be necessary. And the owner says since they were hedged, the vines have been growing back.  On average, about 6 or so leaves per cluster now. My guess is that more leaves will emerge and that in a month there will be longer shoots and that there is a possibility these grapes will ripen and who knows, produce the vintage of a lifetime.

What do the experts say?

A Drop to Cure, an Ounce to Kill: Whoops!

I noticed a powdery mildew outbreak in the Aglianico vines along the shed. I had this coming as the canopy is mismanaged, not allowing good airflow. But, I've learned a few things since last year, when mildew spread across half of the vineyard and I found it difficult to control (and lost 1/2 of the Petit Sirah and 1/2 of the Grenache crops). There's miracle, organic, JMS Stylet oil that arrests mildew outbreaks. The recommended dilution rate with water is 1% to 2%, so I remembered from elementary school there are 16 oz to a pint, 32 oz to a half gallon and 64 ounces to a gallon, right?* So if there are 64 oz to a gallon then I should blend in 6.4 oz of stylet oil per gallon, right? Wrong! The correct amount is .6 oz. What was I thinking?! Alas, I overdosed the vines. Fortunately, light was running out that evening, and I only attacked the worst spots, and I got the dosage correct for the rest of the block. The two pictures above show dead leaves and shriveled grapes as a result of my mistake. I've heard that vines are tough characters, so I think these guys may come back with time. The picture below shows healthyAglianico vines I sprayed with the correct dosage. I wonder when they're going to need some water?

*(Wrong! 128 ounces to a gallon! So the correct dilution is 1.2 oz per gallon + / -)

If It's Thursday We Must Be Spraying

Frank,

Looking forward to seeing you on Thursday. There's been a "cold wave" in these parts with fog each morning and moisture on the vines. The afternoons have been warming up over 70 degrees, and the mildew index is at 100. It's been two weeks since the last spraying, and we've been busy removing excess laterals from the fruiting area. The vines will be ready for another spraying on Thursday.

Based on our experience last time, here’s what I suggest:

Start at the “back gate” (off of Merlot Mike's road) at the top of the hill (by the shed). I’ll leave the back gate open and put some 2 X 4’s up there to make it easy to unload the sprayer from your truck. There’s a hose by the shed you can use for water.

The whole vineyard uses just shy of a full tank of your 32 gallon sprayer. We have 1,150 vines spread out over 2 acres. I suggest “dosage” as if you’re dosing 1.5 acres.

Let’s use Rubigan. (We sprayed 2 weeks ago using Rally.)

FYI, we are battling a mildew infestation on the Aglianico vines – this is the block at the top of the hill around the shed area (flat area at top). I sprayed JMS Organic Stylet oil one week ago. Things seem to be under control. But if you see they are out of control, let me know.

Using your power hose, not sure if it’s possible to control the stream so you get broader leaf coverage, but if so, the foliage is thick, and I hope you can cover it all.

I gave in and watered 3 rows of Tempranillo vines (at the top in a rough area) on Sunday that were beginning to show signs of stress, but other than that, have not watered vines (except for Admire treatment). Let me know what your impression is about signs of stress vines are showing (or not showing) and if there’s a need to water soon. (All that vigorous growth you're seeing is the work of nature and the 15" of rain we had over the winter.)

Please bring invoice for the Admire treatment and Thursday’s spraying. I’ll leave a check with the Queen. Would like you to leave with a check -- it's good for cash flow.

Please pencil us in for July 8th (Thursday) or the 9th. Based on my experience last year (and talking with other vineyard owners), the Aglianico vines will very likely need another spraying.

Call me with any issues or concerns. Thanks for your help, and if it’s possible to enjoy the work (or at least the views), then enjoy. (Be sure and grab a tangelo; they’re delicious!) And watch out for that snake out there among the rocks.

Cheers,
Bluey & Craig
