Bird nets

After verasion, and the grapes are near being ripe, they become more attractive to birds. I read of small vineyards being stripped clean in just a few hours. I only will have a small crop this year, but I think I should try to protect them. I looked at possibly buying audio deterrents ... these are recorded bird distress calls, played back at random to deter birds. I also looked at visual deterrents. Much of what I read claims that the visual deterrents are not very affective. And finally I looked at physical barriers.

Audio deterrents
-----------------------
Pros:
-easy to put up
-lasts many years
-moderate cost
-other growers in Wisconsin claim successful use
-may attract other predators, which may aid in keeping birds out
-unobtrusive visually
Cons:
-Needs AC, or car battery, if battery needs to be changed frequently or recharged
-birds get use to it
-questions about effectiveness
-may bother neighbors

Visual deterrents
-----------------------
Pros:
-fairly inexpensive and durable
-often easy to erect
-no noise to annoy neighbors
Cons:
-looks goofy with junk all over the place
-unproven or not affective

Physical barriers (nets)
--------------------------
Pros:
-Very affective
-One time cost
Cons:
-difficult to put up
-difficult to take down
-can be expensive for large vineyards


Since the audio and visual deterrents are not known to be affective, and I only have a few hundred pounds of grapes to protect this year, I decided to get some bird nets. I don't have a lot of vines to cover this year, so I got 4 nets that are 14' by 100'. These should comfortably cover the vines with the most production.

July 28 - July 29 Things look good.

(Sampson Valley Vineyard at Sunset July 29, 2006)

Over the last 4 growing seasons, it seemed like I would find more problems than success at the vineyard. This year has been MUCH better. I still finds lots of things to work on, but at least things look pretty good every time I get out there.

We got lots of rain over the last couple of weeks. Things look really good. Disease pressure is still quite low. Some signs of powdery mildew, but not too much. Nothing like last year. We have had some very hot weather recently. Two weekends ago, we were in the mid and upper 90's this weekend we were in the upper 80's to mid 90s and will be near 100 F the next couple of days.

No signs of verasion (when the grapes turn to their final color) starting. Last year it happen about the second week of August. Over all things look good. It appears as though I have had 100% success with the fresh LaCrescent plantings. Most seem to be doing well, even the ones that were hit hard by the rose chafers earlier this June. I sprayed RoundUp around them to kill the weeds and grasses. I used a 2 ft high and 2ft in radius homemade cardboard tube to protect the vines as I sprayed. I also sprayed around the Seedless concord which are also are not producing this year.

On Saturday, I sprayed the entire vineyard with Kaligreen. This will be the last spraying I do before harvest which I expect to be around Labor Day this year. I used a rather light spray schedule this year (but more that nothing like the previous years.) It appears to have been very beneficial.

The experimental vinifera vineyard is still battling the deer. It looks like the deer are visiting fairly regularly. Decided to try a trick I read about on one of the grape growing groups. Using high pound test fishing line. I strung 40# test around the plot... I am not hopeful, but until I get the high tunnel up in the next few weeks, it is all I have. Since this is just temporary until I get the high tunnel up, I didn't want to invest in another solar fencer. Speaking of solar fencer, I noticed some odd burning and blackening of some of the grape vine leaves in the park vineyard on the bottom row. It didn't take me long to realize that the burns were from the fencer! The shock from it is very light ... Kind of like a static shock, so I was surprised that it could damage the foliage. Anyway I moved the fence back a few feet from the vines to keep the foliage from getting anymore damage.

We have grapes!



It has been a while since I have been to the vineyard. I was out of the country for over a week, so this weekend was the first time in 3 weeks that have I been to the vineyard.

In general I had good news. No significant signs of insect pressure and no signs of disease. We had good rains a couple of weeks ago that gave everything a good boost.

I spent most of the weekend weeding, mowing and spraying.

After 3 weeks everything needed a good mowing. I then had to weed the new LaCrescent vines. I also removed the floating row covers that about 10 of the LaCrescent had on them. I don't know how much good the row covers did. The vines without the covering seemed to rebound nicely from the rose chafer damage, with no new signs of damage. The vines under the row covers seemed a bit stunted, and seemed to get a bit of a heat shock when it was removed. I think I may go back to the vine tubes next year for new plantings. However, I think I will get the snap together kind, and only use them the first year.

The concord did look terribly perky. Only a few vines are growing well. No panic from me, since they were really just planted for table grapes and I am more interested in wine grapes.

The La Crosse still look kind of poor. A few are doing well, but they just haven't recovered from all of their traumas over the last few years. This may be why there were so few grapes on the Saint Pepin. They need to be pollinated from another grape variety, and the LaCrosse they were planted next to did not have many flowers.

The Landot Noir, and Saint Pepin are both growing well. If the Landot Survive the winter, I may have a small crop on them next year.

The foch in general look better than they ever have. The four year old vines will even produce a nice small harvest. I estimate about 120 lbs of grapes ... maybe a little more. Not a lot, but it's a start.







I also sprayed a fixed copper spray to control downy mildew, blackrot and powdery mildew. The spray I used was Kocide 2000 (in which copper hydroxide is the active ingredient) ... not Omri approved, but still considered organic I think. ( not that I am seeking organic consideration.) I used about 1/2 cup of Kocide in 25 gallons of water. This is equivalent to 1 lb per 100 gallons. Which is on the low end of the suggested application rates. The temperature was in the upper 80s when I sprayed with a light breeze out of the South West. (I sprayed at about 11:00 am on Sunday) The leaves seem to dry very fast. I did not spray the top LaCrosse row since it was next to the Concord which is copper sensitive. 25 gallons total covered the rest of the vines. When the vines are mature, I estimate I will need about 50 gallons total. I also used about 2-3 ounces of spreader sticker.



In general disease pressure was low. I'm not sure if this was due to the weather, the dormant lime sulfur spray, or the kaligreen spray in June. What ever it was, the vines sure do look healthy.

The one major bad thing I saw was the deer eating the vinifera again. I hope they'll recover, but it has been a struggle with them. I didn't spend too much time on them this weekend. I hope to spend more time the next time I am up there in a couple of weeks.

Status mid June ... some herbicide damage

A good week!



Things looked pretty good the weekend of June 17-18. It was hot and windy this weekend. On Saturday, it hit 91F. Unfortunately, it has been a couple of weeks since the vineyard has seen any substantial rain. We could really use some right now.





The spraying last weekend seems to have been effective. I saw only a handfuls of rose chafers on the vines. I saw almost no signs of the grape flea beetles nor their larvae. The rose chafers were devouring a nearby rose bush and every milk weed in the area.

Speaking of insect damage. I did see something very interesting. In the vinifera, I purposely left any milk weeds I saw last weekend. This weekend the milk weeds were devoured by some type of insects. Completely skeletonized/defoliated. But I have never seen a bug on any of the vinifera or any damage from insects. What's protecting these? The root stock? The varietals?

I gave the vinifera a good weeding/tiling in preparation for the high tunnel. The fence seems to have discouraged the deer over the last week. At least I didn't see any fresh deer damage.

Vines at the park have entered full bloom. A little later than I would have expected since everything had been early up until now, but the cool May and cool shots during June slowed things down a bit.



Herbicide damage?
On Saturday, the vines at the park looked fine, but come Sunday, they had curled bubbly leaves. Looks like maybe herbicide damage? Possibly 2-4d drift? I have read that 2-4D volitilizes in hot weather. Since we haven't had a rain in so long, the herbicide may actually be from several days ago? Just guessing.

Give 'em a fighting chance

Bunch of pictures from the vineyard this weekend. Here is a picture of the vineyard from Sunday afternoon.


The vines are getting hit from the weather, bugs, and more bugs. Well, I decided it's time I give the vines a fighting chance.

The Rose Chafers are back, and back in force. This is the forth year in a row they hit my vines. Last year they showed up on about June 15, this year it was maybe June 10 or a day or two earlier. My notes only note them showing up in June the previous years, and were not detailed enough to know the exact date. Interestingly, the last two years appearances coincided within a day or so of the cutting of the hay field that the vineyard borders. Related? Possibly.
Here they are attacking the LaCrescent vines
The vines that hadn't been attacked yet were covered with floating row covers. Unfortunately, the row covers really could only be used on the newly planted vines. And the jury is still out on whether they will even work.Benjamin Franklin was quoted as saying that the definition of insanity is to do the exact same thing over and over and expect a different outcome. I haven't really sprayed or done anything significant to eradicate them. Well this year was different. I really didn't want to lose another year on the Concords, and lose a year on the LaCrescent. So after surveying the extent of the infestation ... significant, and since bloom hadn't really started, I decided to spray Sevin. I thought it was either use it or lose some vines. The LaCrosse were hit every year by them, and they are in their forth year and will still not bear a crop! The Sevin looks like they did a number on the Rose Chafers... at least the ones that were part of the current infestation. Check out the picture....


I am also seeing a lot of damage from the grape flea beetle and its larvae. Several of the laCrosse got hit the hardest, and it looks like no or very little crop off them again this year. The LaCrosse definitely have had it the hardest. It's hard to believe I haven't lost one of those vines completely yet.


You can see the grape flea beetle larvae on the left ( a bit blurry) You can also see the damage to the canopy of the foch on the right.


The LaCrosse showed the most damage. I read that the Larvae damage from the grape flea beetle was typically "minor" ... ha! minor?... look at the picture!

The Sevin should also knock them back too. I'll evaluate status next weekend, but the next spray of Sevin may have to wait until after bloom, which I expect to start in force in the next week or so.

And to top it off. I had a frost Sunday morning!!! It's June 11th!!! A FROST?!! It only hit the lowest corner where the air drainage is poor, and only the foliage closest to the ground, but come on.... here is a picture of the a vine that got it pretty good.Not all is lost . Some of the foch was looking quite good. See below

Rose chafers return and so do the deer

Well, the Rose chafers are back ..... they already laid waste to about a half dozen laCrescent, and about 3 concords. They really like the young foliage. I found them on the saint pepin and foch too, but the most damage is to the recent plantings. I also saw considerable damage from the grape flea beetle and its larvae. The hit some of the foch, but nothing the vines can't handle. They hit some of the saint pepin harder, but I think they will spring back. I sprayed the top 5 rows of vines with Omri approved Insecticidal Soap. It is organic, although it should not be sprayed on vines from bloom until shatter. The top five rows are not in bloom yet, nor do I intend to allow them to bear fruit this year. It looked like it may already be working on some of the rose chafers.

I also sprayed kaligreen on the vines this evening. This is Potasium bicarbonate. Used primarily to kill powdery mildew. Also organic.
The deer struck the pit vineyard again. Did quite a bit of feasting. Kellan and Brent helped me put up a 4 strand 6 foot high fence. Hopefully it will slow them down. They also were nibbling on the vines at the park; especially the bottom row.
Although their damage was much more severe at the park.
In addition to mowing and spraying, I spent a lot of time pruning suckers from the vine bases, and retraining some of the vines with bad trunks etc. I'll try to take some pictures tomorrow and post them.

Some hot weather and more rain & vinifera survival rates

This past weekend brought more rain and some hot weather to the vineyard. Saturday night June 27, we got a pretty big storm which added 2.5 inches in one shot. Added to the about 4 inches earlier in the month means plenty of moisture in May. Saturday, Sunday and Monday also had highs in the upper 80s and low 90s. Things are really sprouting now.

While the saint pepin did not get hit too hard by the frost in early May, it did get nailed by the grape flea beetle pretty hard. Things will be okay, but a lot of mishapened early leaves. I may try to spray with sevin next spring in mid to late April, and early May to limit the damage next year.

Nearly all of the freshly planted LaCrescent have already got leaves, maybe 2 or 3 of the 48 don't have leaves yet. In the past, some plantings didn't get leaves until late June, so I may still have 100% survival yet. I sprayed Round up between the vines to suppress weeds until I can get stone down. I still haven't planted the extra vines sent. I may plant them on a gravelly hill side in the back 40. I noticed that they are sprouting pretty intensely now.

I haven't done my first fungicide spraying yet. I plan to do it the weekend of June 10. Probably a little late, but you do what you can. I plan on spraying the kaligreen this time, and fixed copper, and kaligreen the weekend of the 24th. I may spray some sevin also especially on the concord and LaCrescent vines which are more susceptible to the rose chafer damage. The rose chafer isn't due until about the June 15, but since everything is about 1 -2 weeks early, they may be there by the end of the first week in June.

I also scouted the vinifera vineyard.... I lost several vines to rodents. Of the 75 vines I have 44 left. Most of the vines lost were the chardonnay.

Here are the vine types with there row positions and survival from west to east
S F M F C
8 9 13 10 4

S=Cabernet Sauvignon
F=Cabernet Franc
M=Merlot
C=Chardonnay


Finally, I pruned off many of the suckers from the bases of the foch. Several vines in the lower south east corner, are going to have to be retrained from the bases. They were pruned back or sometimes the tops were lost either due to frost or freeze problems.

We did get bit by the frost on Sunday night and Monday night May 21-22. But mostly just the lower buds and lower shoots, especially in the lower south east corner, but not nearly as damaging as the May 6 freeze. (many of the dead shoots and buds from that freeze are still visible.)

Missed me by that much

Well my scouts(my Mom and brother) tell me the frost was
very light, no major damage that they could see. I'll know for sure this weekend when I get up there.

We are expecting much warmer temperatures over the next several days. If things have progress well enough by this weekend, I plan on spraying.

Another frost ? Grape flea beetles.

Frost/freeze predicted for tonight. Right now we are on the edge of a cloud mass. If it stays far enough north I should be spared. If it goes south, radiational cooling may cause another frost.
Most of the secondary buds haven't broken yet, but some primaries on the st pepin have just begun to break. Overall it would not be good timing.

I spent the weekend mowing and trimming around the vines. Vine winter survival looks excellent. Surprisingly, I haven't lost a single La Crosse vine from last year .... I'll have to recheck my notes, but I think I had some marked as completely dead, so imagine my surprise to see some life on every single vine! Also it looks like I only lost one seedless Concord; I am very surprised, especially after the severe damage from the Rose Chafers last year.

My scouting also revealed more significant grape flea beetle damage. I'll have to read up on how to best control them. Sure are a lot of dead primaries from the frost a couple of weeks ago. Very sad to think how healthy things were looking prior to that frost, and now all the damage. Oh well.

I got the irrigation equipment installed. I still need to work on the drip lines, but the pump and hose from the water to vines is all set up. Only found one leak. It may have been caused during storage, I may try to leave it in place next year. I'll just have to make sure the water is purged first.

The vinifera look a bit better than I thought. still lost several due to rodents, but enough survived to make it worth it. I will have to replant a dozen or so.

Satellite image of last week's freeze


I pulled the data from the GOES-12 weather satellite for the freeze last Friday night. I enhanced it to show where the temperature was above and below freezing. I then made an animated GIF with cross hairs on a few select vineyard locations that I knew the exact latitude and longitude. It is somewhat hard to tell what is what, but the animation helps. If you are planning a vineyard, you may even be able to spot good locations that would be less likely to experience a late spring frost. http://jerroldr.googlepages.com/home

LaCrescent vines arrived and planted

It has been raining pretty steady for the last 3 days. As of yesterday(Friday) we had 2.5 inches at the vineyard. The the corrected shipment of vines also arrived yesterday. I was able to plant them between rain showers. A total 48 Lacrescent were planted. I got 60 vines total, although I am not sure why that many was ordered. This may have been a mistake on the vine suppliers part. Not sure.

I'll probably put the remaining LaCrescent into a trench until I can plant them in a couple of weeks. I still have to decide exactly where I will put the vines.


Took a look at the frosted buds on the vines. They look pretty dead. I noticed that most of the Saint Pepin had not broken bud, so I may get some reasonable production from those. I also noticed some damage from grape flea beetles. Remains to be seen how much I'll have to deal with them.

The vines arrive ... well not exactly

My vines arrived today. I planned to plant two rows of LaCrescent vines .... unfortunately, they only sent 10 LaCrescent vines. The rest were LaCrosse! I called Double A hoping that they were just marked wrong .... nope ..... they sent the wrong vines. They told me I could go ahead and keep the LaCrosse, and they sent out my LaCrescent this afternoon. I should get them by Friday.

I had all of my holes ready before I discovered the mistake, so I planted the ten LaCrescent vines that were sent. I mixed in about a tablespoon of muriate of potash with each vine.
I heeled the 50 LaCrosse vines on the Northwest corner of hill under some box elder trees. I then covered them with a tarp. I'm not sure where I am going to plant them. I am out of space near the park. I may put them on the east end of the same field.


I also got 6 replacement cab sauvignon vines that died immediately after planting last year. I planted them in the same location where the other vines died.

The frost damage

Looks like the frost damage may be a bit more severe than I first thought. It looks like about 80% to 90 % or more of the buds that had broken, died. I thought that I already saw some of the secondary buds swelling. But these may be a second primary bud .... a similar thing was seen in Michigan a few years ago ... see http://www.canr.msu.edu/vanburen/grp423.htm

Even if those aren't a second primary, and is the secondary, all is not lost. Unless we have another freeze :( The extended forecast does not show much of a warming over the next week or so, maybe even another freeze next week. I hope not.

While yesterday was quite productive, with temperatures in the 60s and 70s. Today was not. It rained steadily almost all day. We got a little less than a half inch at the vineyard. I was able to amend the soil where I will be planting the LaCrescent later this week. I have about 48 LaCrescent vines to plant. The vines will be going into two 200 ft rows. I added 5 lbs of muriate of potash to each row, and about 7 lbs of aluminum sulfate to each row. The potash was to correct the low potassium, and the aluminum sulfate to lower the ph ... the soil is quite alkaline in our area.
Tomorrow, I will try to get the holes for the vines ready. Hopefully the vines will show up tomorrow, and I can get them in the ground. But they may have to wait until Thursday or Friday ... when the temperatures are in the 50s and it's raining heavily.

Frost in the vineyard

Well the early spring finally caught up to the grapes. Early on Saturday morning I had a frost/freeze at the vineyard. I don't know the official low in the vineyard, but it was at least 31 F by the house; my brother commented that there was actual ice on the car outside. He estimated about 28 or 29 F at the vineyard.

Bud break began earlier in the week; I estimate about 75% of the buds had broken by Friday night. The freeze damage was scattered through out the vineyard, and I am not sure how severe the damage is yet. Some of the shoots that were already an inch or more long showed some severe damage. Some of the buds that had broke more recently, appeared as though only the outer leaves were damaged. I tried to take some close up pictures, but the digital camera with auto focus didn't work too well ... here is my best attempt at a picture of the damage on one of the vines.

The damaged caused the outer bud leaves to look black or brownish. I hope to assess the severity of the damage later in the week.

After a warm start to the upcoming week, it is suppose to turn colder and wetter starting Wednesday. The LaCresent vines that I am planting this year, ship on Monday, and I should receive them by Wednesday or Thursday. I plan to plant them the day after they arrive.

I have the week off to do vineyard work this week. On tap for tomorrow is trellis work, application of some herbicide, and other odds and ends.

Wednesday, April 26, 2006

Whew ... Bullet dodged, but not out of the woods yet.

Only got to the mid 30s last night. Still lots of time for a frost yet this spring. I am hopeful however that things will stay warm. The 14 day forecast still shows no sub freezing temps.

Tuesday, April 25, 2006

Frost possible tonight

The report from the vineyard (via my Mom) is that the buds have swollen to the size of marbles ... I think some may have broken, but I'm not there to verify how many. The forecast for tonight was a low of 29-34 F ... so I am a bit concerned, but I think things are not far along enough that even a low of 30, 31 or 32 shouldn't do too much damage. The last temperature Observation from Pulaski (about 11 miles from the vineyard) was about 42 F, and the dew point was 32, so I am feeling a little better, but we will see in the morning.

My foch and cab franc in the backyard broke bud late last week, and may be susceptible tonight, but I'll take my chances. Talked to Norm Stilson from the Prairie Home Vintners club tonight, and his vines are swollen but have not broken, his vines are on a west facing slope. One of the disadvantages of my vines being on a south facing slope, is the risk of frost injury in the spring.

Bud break in Madison

My Foch and Cabernet Franc have broken bud in Madison. Forecast is for a possible light frost next Tuesday Night/Wednesday morning. My backyard usually stays warmer, so hopefully I'm safe.

I don't know if the buds broke up in Sampson yet, so I'm not sure if I should be concerned.

Buds swelling in Sampson



My weekends are full the next 3 weeks, so I took the opportunity to do a little work on the Saturday before Easter Sunday. The foch buds are really swelling. I hope they don't break soon, because there still is a lot of time that a frost is possible. I was encouraged by how little winter kill I experienced.


It's been drier up in Sampson than down in Madison. We could use a little rain up there.
I took the tarp off the second half of the experimental vinifera. These looked better than the first half I uncovered. When I prunned them they were nice and green inside.

Unfortunately, some of the vines look like they were a mid winter snack. I am concerned about the vines that were heavily gnawed by rodents. At least one chardonnay vine was definitely killed. I suspect several others may have also died. I thought the winter might get them, but it looks like it may have been mice.

Purple foot Acid tester

I started testing the purple foot acid tester. I am posting my pictures and results here:

Spraying Lime sulfur

I took it easy on Friday, but Saturday it was back to work. I was able to find lime sulfur at Stein's in Green Bay. I had contacted a supplier near Madison, but they hadn't replied to my email, so I was very happy to find it in Green Bay. Lime sulfur used as a dormant spray is used primarily to control anthracnose. From what I learned at the MGGA convention in February I think my vines had it last year. My Foch are a sulfur sensitive variety, so lime sulfur can only be sprayed when the vines are dormant. Since foch are sensitive to sulfur I decided to only spray 3 out of the four rows of Foch. The top one and the bottom two. Lime sulfur while considered organic is still quite poisonous/dangerous, so I wore the appropriate goggles/mask, and protective clothing when spraying. It also smells like rotten eggs, so it's also a good idea to let neighbors know. Luckily there was little to no wind, and spraying went well with the exception that the sprayer I bought was a "lemon." I ended up spraying 1 of 2 rows of Lacrosse, the row of Landot Noir and 3 of the 4 rows of foch. I did not spray the St Pepin or the seedless concord. I may spray the st pepin at Easter time if they are still dormant. I may also hit the Vinifera at that time too.
