Taking Cuttings for Next Years Plants

It has been a mild fall in Edmonton and the relatively warm temperatures have continued on into early December. Up until now the coldest overnight temperatures were -14c, however, we're expecting some real cold in the next few days of -25c to -30c. So on December 3rd I took cuttings from the Marechal Joffre and Acadie Blanc vines in Edmonton.

I pruned the vines back to about 5-6 buds remaining and took the rest of the canes to utilize for cuttings. Each cane was then trimmed down to 3-4 bud lengths. The Joffre canes look good but there was very little usable cane from the Acadie. I had moved the Acadie mid summer and I think that most of the vine energy and carbohydrate storage has gone into the roots for the winter. As such the canes were week and many had died back nearly to the base of the vine by the time I had taken the cuttings.

I got about 25 cuttings of the Joffre and just a few cuttings of the Acadie. Click on the cuttings picture and you can see the nice green interior of the canes at the place where it was snipped. These cuttings I'll be treating in the spring to eradicate any pest that may be on them as they will be going to the experimental vineyard in BC (see the last blog Sources of Vines Nov 23). For now though I have to store them until March 2010, so for about 90 days. In doing so I need to preserve the moisture that is in the cuttings and to reduce chance of mold and spoilage and to keep them in the dormant stage.

To keep them moist, I've wrapped the group of canes in slightly moist paper towel and then wrapped the whole group in a plastic. I've read that some will dip or wash the cuttings in a mild bleach solution to reduce the chance of mold but I'm going to forgo that. To keep the canes dormant I'll store them at the back of my refrigerator to keep them cold. I have a thermometer with them and it shows the temperature is at 3-4 degrees c.

I'll open the parcel up in early March to do the treatment of the canes and then start to root them.

Sources of Vines

I've grown all my vines from cuttings and for the most part have had very good success. Where I've had difficulty with cuttings has usually been a result of poor quality cuttings that I've received from a supplier.

Getting the cuttings to grow is a very easy process;
1) get the cuttings from a supplier, keep them cool, wrapped in plastic with a slightly moist paper towel in the refrigerator until your ready to go.
2) soak the cuttings in room temperature water for 24 hours before you plan to plant them.
3) Using a sharp pruning tool, nip about 1 cm off the bottom of the cutting.
4) Dip the cutting in a root hormone (I use the powder stuff from Home Depot).
5) Plant the cutting in a 4" x 4" biodegradeable (compressed peat moss) planters and fill with 50/50 peat moss - perlite mixture.
6) litely pack the planting mixture into the pot around the cutting.
7) Place the pots on a heat mat so that the bottom of the cuttings are warmed to about 75-80 degres F.
8) Water good the first time so the mixture is moist. After the first day you'll probably see the sides of the pots have soaked up most of the water.
9) Water again when the sides of pots are drying out.
10) Keep the pots in a cool (60-65 degrees F), dark room for the first 2-3 weeks (this allows the cuttings to begin to form roots before the buds leaf out).
11) After 2-3 weeks give the cuttings lite and more heat (70-75 F) room air temp.
12) After about 4 weeks (maybe sooner - maybe later) you'll probably see roots poking out the bottom of the pots and your cuttings will have leaves.
13) When you see the roots poking out, transfer the plants to the ground if it's warm enough, or to larger pots until you can plant them outside.


IF YOU WANT TO PURCHASE GRAPE CUTTINGS GOT TO GRAPE VINE SALES ON THIS BLOG.


Unless you are intimately aware of the regulations regarding movement of plant materials (grapes or otherwise and this includes cuttings) in and out of provinces in Canada with respect to the Plant Protection Act, I STRONGLY RECOMMEND you contact your local Canadian Food Inspection Agency (CFIA) office to ensure you can do so legally. Last thing you want to do is break the law and/or be known for being the person who importing a pest from another location to a place where the pest didn't exist.

I mentioned in a recent blog about new varieties for 2010 and about adding Joffre to the test vineyard in BC. The Joffre cuttings are going to come from my plants that I'm growing in Alberta. Now, there is no movement restrictions on cuttings comming from Alberta to BC, HOWEVER, the cutings originally came from Nova Scotia and there is a ban on movement of grape plants or plant material from Nova Scotia to BC. There is no ban on movement of cuttings from Nova Scotia to Alberta. However, to reduce any possibility that a pest got transported with the original cuttings and now exists on the plants I have in Alberta, the CFIA would like my cuttings that I'll take from my Alberta vines, treated here in Alberta before moving them to BC. The treatment, is a simple process of submerging your cuttings in hot water. I wont go into the full details of the treatment here but once you complete the treatment, which eradicates the pest, the CFIA will provide a "movement certificate" which then will allow me to legally move the cuttings to BC and more importantly ensure I'm not going to bring a pest to BC on my cuttings.

If you have any questions on movements or pests, call your local office of the CFIA.

I'll do an update on the treatment, process, costs, and propegation success rate this spring when I have the treatments done.

Frost Control and Bird Netting

We're training the vines up to a 5 foot fruit wire in 2010. So far it appears the winter cold is not as much as an issue as early fall frost. So by raising the wire from 22 inches to 5 feet we wont have the bennefit of the snow cover in the winter however, the fruit wire at this height offers a few degrees of frost protection.

Good research on this
http://www.nzwine.com/assets/frost_review.pdf

We're also looking at bird netting as we are going to need it but there are some on the market that provide a degree or two of frost protection. Were going to try this out and see if it works.

We're not really worried about the frost because the varieties we've chosen appear to be early enough for our site that it should not matter. Having said that, being able to let the grapes hang a week or two could do wonders for the juice chemistry perhaps increasing the brix 1 or 2 points while dropping the acid to levels if it happens to be a bit high - we'll see.

New Grape varieties for 2010

We have decided to add some new varieties for 2010 and drop the Perle of Csaba. The Perle, while early, apparently is very prone to disease. Disease resistance is a primary consideration for the vines we want to plant so with that in mind we've decided not to plant it. As it stands we have Ortega and will be planting Seigerrebe in 2010. Both are early and both have disease pressures - we don't need another one. However, I did read on the BC government agriculture site that Ortega apparently has some disease resistance to rot and powdery http://www.agf.gov.bc.ca/cropprot/grapeipm/index.htm ---- we'll see.

In 2010, with the Seigerrebe we are going to plant Acadie Blanc, DeChaunac, Lucy Kuhlman, Marechal Joffre, and Seyval Blanc, Zweigelt, and Castel.

The Acadie Blanc is a Nova Scotia wine staple that produces an excellent white wine that can be made into a few different styles similar to chardonnay, chablis or a sparkling wine. It is early and disease resistant. I've had this one from several vineyards in Nova Scotia and all have been good to very good.

The Dechaunac and Zweigelt is mid-season and would likely test the limits of our ability to ripen these varieties not by way of heat but in frost free days. The Dechaunac has some disease resistance and can produce excellent red wines not dissimilar to Pinot Noir with good aging potential. House of Rose Vineyard in BC makes an excellent Dechaunac. We enjoyed a 1999 vintage of Dechaunac this year (10 years old) from the House of Rose and it was at the end of it's optimum shelf life but still excellent. Zweigelt to me is like a Gamay and by some accounts also has marginal disease resistance. Arrow Leaf Vineyard in BC makes a nice Zweigelt. Both varieties are heavy producers.

The Seyval Blanc is also mid-season and produces an excellent white wine that can be made into a few different styles. Jost Vineyard in Nova Scotia does this one better than anyone else I've tried.

Lucy Kuhlman and Marechal Joffre are sibling vines to Marechal Foch and Leon Millot. All four were created from the same cross by Eugene Kuhlman of France. The LK and MJ both are said to be earlier ripening than the Foch or Millot and have excellent disease resistance and cold hardiness. Sounds good so far. I've tried two vintages of Lucy Kuhlman from different Nova Scotia vineyards and both had a slight herbaceous flavour but nice fruit and high brix/alcohol. I've not seen anyone who makes a Joffre varietal wine and few that grow it, seems to be used more as a blender. However, some literature (Northern Wine Works) points to Joffre as having similar flavour qualities to Foch, but a little less fruit flavour and also less acid at harvest - well see. (see the September 9th, 2009 post Grapes in Edmonton for more on Joffre)

Castel 19637 is early ripening, cold hardy and disease resistant. It makes an excellent mid weight red wine. Wine quality from this variety in Nova Scotia is excellent. Some grow it in BC on Vancouver Island for a varietal - Cherry Point Vineyard, but others use it more for a blender. Link to full blog

Agria Wine and Grapes

It has been a while since I've posted a blog but have to talk about a wine I recently tried. It came from Southend Farm Vineyard in BC (http://www.southend.ca/sefv/Welcome.html). The wine is made from the Agria grape also known as Turan. In fact this is what Southend call's it "Turan". This red Hungarian variety has found a home in BC on Vancouver Island and the other Wine Islands between Vancouver island and the mainland. This variety is a very early ripening red vinifera grape and a robust producer with deep red juice. We are testing this varety at our site.

Now, I've tried a few other wines made from this variety incuding a big red not unlike a big Italian red which came from Marley Vineyard which was quite nice. Also, another nice one with fruity strength and some age potential from Crabrea Vineyard. Both these are vineyards in BC in the wine Islands.

What is different about the Southend Farm Vineyard Turan is that they craft the wine the same as you would a white wine by crushing and pressing the grapes and fermenting the juice without the skins. You wouldn't know that it was fermented without the skins by looking at their Turan wine, as it has a beautiful cherry red colour. This is the natural colour of the juice from the grape. This wine has a pronounced fruity aroma to it, crisp taste and finish not dissimilar to a lite crisp white wine. For me this is a very nice summertime wine, that should be enjoyed chilled.

Final Grape and Climate Data 2009

The experimental vineyard got frost on October 1st (-1.7c) and this ended the growing season. Actually, as all the berry cluster we kept this year are about 1 foot off the ground, some of the Leon Millot got hit with frost on September 21st. The data logger is 4 feet off the ground and registered a 0.8c degree low on September 21st but at the ground level there was frost and it was probably 2-3 degrees cooler there than at the 4 foot level. Aside from the September lows the first really good frost was on October 5th at -2.7c. The last spring frost at -1.7c was May 9th. So by way of the data logger we had about 145 frost free days (greater than -2.0c) this year. Not great but it was a cold late spring by about 2 weeks by all accounts in the region. I had thought our site would have about 150-160 frost free days on average but I'm going to lean to a more conservative estimate of 145-150 frost free days on average. This will only present itself in time.

The Growing Degree Days for the year are as follows;
May average was 12c
June average was 17c
July average was 20.2c
August average was 19.2c
September average was 14.1c

Total Degree days (May 1st-Sept 30th)was average was about 996 with a 10c base. We had about another 50 degree days (some in April and October) for a year growing total of about 1050.

The Leon Millot that got hit by the frost September 21st, stopped gaining suger at about 15-16 brix - seeds turning brown.
The other Leon Millot that made it to September 26th, had average 19 brix - seeds brown, nice flavour, acid did not seem to be a problem (by taste, acid&ph wasn't actually measured).
The Ravat 34 had a brix of 18 and had great flavour, somewhat like Riesling. This will be interesting if we can pull enough grapes off this one next year.
Dispite having covered the Agria with wire mesh some critter ate all the berries. Must have been a small animal but I don't know what it would have been.
All varieties appear to be hardening off well and through the season showed no disease on the leaves or berries (of the few berry clusters we kept).

Update on Edmonton Grapes

Photo of the same St. Croix cluster as the picture from September 9th.

Tested the St. Croix for brix today spectrum range
was from 11-16 so I'm estimating a over all Brix of about 14.
That is about double since last week.

Update -
September 20th, St. Croix brix 16, Joffre brix 19
September 22nd, St. Croix brix 17, Joffre brix 20
September 24, St. Croix brix 17
September 25, St. Croix brix 18 and the Joffre is 22 brix.

We are suppose to get another week of good weather then a freeze on September 25th. Will check them next Tuesday or what ever the last day is before the freeze.

Grapes in Edmonton

Photo's 1) Joffre cluster with most of the berries gone after testing brix
2) St. Croix cluster

Some details on grape varieties growing in Edmonton. These include St. Croix, Marechal Joffre, Edelweise, and Acadie Blanc.

These varieties are disease resistant and cold hardy. The Joffre and Acadie Blanc are cold hardy to about -30c and the St. Croix and Edelweise cold hardy to about -33 to -35 c.

We had about 18 inches of snow on the ground this past winter and had cold of -35c. As a result the Joffre and Acadie died back to the last buds an inch above the soil. The Edelweise and St. Croix budded out between 6 and 12 inches above the soil. The Acadie and Edelweise had no flowers bu the Joffre had one small cluster which flowered about July 4th and the St. Croix has about 7 clusters which flowered about June 27th.

The summer came late about 2 weeks or so and it has been a cool dry year in Edmonton. The degree days are at about 625 - 650 year to date. Historically Edmonton gets about 135 frost free days and 750 degree days of heat, so in theory there is enough frost free days for very early varieties but the winter cold usually kills the canes and buds off. But 750 degree days is very low on the heat.

Veraison on the Joffre cluster started about August 20th and September 5th for the St. Croix. Tested the brix today and the Joffre is about 19 brix (about 70 days from flowering) and the St. Croix is at about 7 brix.

Going to lay the canes right down on the ground this winter to see if that changes the cane and bud survival rate. Hopefully we'll get some clusters on the Acadie and Edelweise next year as well. If you could get the Joffre to survive the winter in Edmonton you'd have a nice grape for this area. Will see how well the St. Croix does before the frost comes.

Moisture from the Air


Photo of Unirrigated Leon Millot, August 9, 2009

I read about a few interesting studies that had been done that measured the amount of moisture that was added to the ground from the moisture in the air - not from direct rainfall. They were conducted in the Mediterranean and in an arid climate. The one study found that 179 mm of moisture fell as rain from April 1st to September 30th but they found that their instruments measured the equivalent of 225 mm of moisture. They concluded that as a function of high humidity and dew formation that the ground received this extra moisture that was not recorded as rain fall. Sandy soils showed the highest increase in moisture from the air (probably because they cool more and therefore a greater capacity to form dew). They measured this by measuring the weight of the soil of which the added moisture showed up as extra weight. Anyway, this is interesting as this amounts to about an extra 30% more moisture in the study.

The reason I was looking for such studies is that every morning in the summer I walk out into the vineyard and the sandy ground is wet with moisture from dew. And the amount is significant in that it appears that there had been a light rain overnight but the rain gauge has only dew on it, not rain in it. I have been wondering how much moisture this would be and if it is use able moisture.

While I can't measure how much moisture gets added to the ground, at our site we have high daily humidity and our nights get quite cool such that we have significant formation of dew (we also have sandy soil). So much that I'd be soaked from hip to toe if I took a 50 foot walk in the high grass and ferns. This may help explain why the unirrigated vines are doing well.

Sunlight

Photo: Typically sunny summer day

In the summer we get great sun at this location with few clouds during the day and sometimes a late afternoon thundershower. Call me crazy but the sun seems to be really intense up here. Does elevation affect sunlight intensity that much at 2000 feet?

But, we are missing a few hours of morning sun and part of the vineyard is missing some evening sun because of trees to the east and north west of the vineyard.

It is obvious that the vines growing in the area that gets the morning and evening shade are not as vigorous as those in areas with more sun.

There is also a massive tree that is too big for me to cut down and it creates a moving shade spot in the south west quadrant of the vineyard as the sun moves across the sky.

We also have a large hillside to the west and that cuts the evening sunlight off at about 7-8pm in mid summer. Nothing we can do about that.

Will take the trees down in the fall or get a tractor in to clear the land where the trees are.

Vine Spacing and Training

Photo Leon Millot with 9 feet of growth this year trained to fruiting wire

The vineyards in France do not irrigate their grape vines and they typically get rain in amounts similar to what we expect to get at our site. They space the vines at about 3-4 feet apart and space rows 8 feet apart or less sometimes. We have used this as a measure of how far apart to space the vines and rows as we hope we can grow these vines without irrigation. As such we have the vines spaced at 3 and 4 feet test distances within the rows and rows are spaced 8 feet apart. This is about 1300 vines per acre.

We have also put a 3" thick mulch of bark and tree matter under the vines to preserve moisture and to provide nutrients to the soil around the vines. The strip of mulch under the vines is approximately 3 feet wide. While it is expected the mulch will help preserve moisture under the vines it will also insulate the soil in the spring, slowing the rate at which the soil warms and then slowing bud break to help avoid late frosts. Theoretically this is suppose to work but we'll see how this works in reality. Of interest is the original three Leon Millot vines that are unirrigated are also un-mulched and seem to have enough moisture and nutrients.

We are trying cane pruning and spur/cordon pruning methods with the different vines to see what works best, what makes quality, and what is easiest. We are also trying a VSP canopy and if vigor, moisture etc permit we'll try a divided canopy. The fruiting wire for the cordon or cane is about 24". This is a little low but takes advantage of the expected snow cover in winter, its insulating value and potential protection from the cold. A 30" fruit wire or even 36" fruiting wire would be ideal, but we're not taking chances with the cold. Maybe years from now when we know the climate a bit better we could change things a bit. Till then...

Climate This Year 2009

Photo: data logger placement.

The year started off quite cool the last good frost was on May 9th at -1.7 c. The Leon Millot planted in fall of 2008 were budding out (full swell) on May 9/10th. Bud break was about May 14 (estimate about 7-10 days late). Flowering was June 28, about 7-10 days later than estimates for an average year (estimated time of flowering is June 18-21). April temperature average was 6c. We had temperature Averages of 12 for May, 17 for June, 20.2 for July and we're on track for a 19 - 19.5 average for August. Thats About 875 degree days since May 1st. If this year is like last and we have a decent September (Average of 13) then we're looking at about another 90 degree days, and likely another 20-30 or so in October before frost. Fall frost is expected in the second week of October but could easily come a week or two earlier. Hopefully we can record close to 1000 degree days (based on daily average) this year, again not bad. What I'm hoping for in September is the high daily heat and cool nights we had last year. The September 2008, day time average high was 21 c and the nights averaged 5 c. The monthly average was 13.


I am going to move the data logger into the middle of the vineyard for next year as it is presently off to the south east of the vineyard in an area populated by trees about 4 feet off the ground. I think the vineyard area may actually be a bit warmer during the day. I also think that the ground level is about 1 degree cooler at night as that sandy soil does not hold the heat well. When I move it into the vineyard, I'm also going to lower it to about 3 feet off the ground in summer closer to the area where the fruit wire is located. I'll move it back up to 4 feet off the ground for winter otherwise the snow may cover it. This should give me a better idea what the air temperature is in the vineyard and around the buds in spring and grapes in summer.

What has been difficult to assess is the rain fall. As we are not at the site all the time we miss the exact amounts due to evaporation. We do know the site got at least 2 inches in April and at least 2 in May. June had 1-2 inches and July and August each had at least 1 inch. So far that is 7-8 inches I've recorded but in talking to some that live there all the time they say there was 3 inches in May and 2 inches in June. So it is possible the site has had 9-10 inches of rain this year to date. Any way you look at it the rain fall has been ok and based on the growth of the unirrigated Leon Millot it has been enough for this year.

I've put wire tents around the grape vines that have clusters so that the birds don't get to them. Will start testing the brix in mid September but will only do two tests a week apart as I expect I'll run out of berries pretty quick with the few clusters I have.

Vines to Plant

Photo cuttings, propegation trays and heat mat


We looked for varieties that are easy to grow, relatively cold hardy, would consistently ripen in our climate and would make nice wine. In particular we were looking for vines that were disease resistant. So we have come up with a group of varieties that fit these parameters well and some that don't fit all the parameters.

Those that are relatively disease resistant, cold hardy, and should ripen consistently (900-1000 degree days and 150 frost free days):
Castel 19637 ( http://www.aberfoyle.org/castel.html ) and Acadie Blanc and Regent (regent is a bit less cold hardy). There is also some great new varieties that have been developed at the Kentville Research Station in Nova Scotia that have fairly good cold hardiness, some disease resistance and are early to very-early ripening. These would appear to suit our site quite well and we will try to get some of these.

In terms of wine from these, our favourite is Castel. It is hard to find but the ones we have tried as varietal are fantastic. Domaine De Grande Pre (Nova Scotia) Castel reserve and Gaspereau Vineyard (Nova ScotiaCastel are worth getting your hands on if you can. Cherry Point on Vancouver Island makes one as well but I haven't tried it as yet.

Others varieties we're trying out that should ripen but are less cold hardy and have lower disease resistance are: Agria, Ortega, Seigerrebe, and Perle of Csaba.

Then there are those that are less cold hardy, lower disease resistance and are believed to be marginal in terms of ripening in our climate: Zweigelt, and Pinot Noir 115.

We don't have all of these varieties as yet, we have more on order for the spring of 2010.
Last fall we planted the first vines. This was three Leon Millot vines which had been grown from cuttings in pots then transplanted in the fall to the ground. This spring we planted another 25 Leon Millot, 15 Ravat, and 8 ortega.

Later in the summer we planted 18 Agria, 15 Regent, and 8 Pinot Noir to go in late summer.

THE GOOD NEWS
The three Leon Millot vines planted last fall (September 15th) were literally planted in holes and given 1 litre of water. They survived the winter and have about 7-8 feet of growth this year. The good part here is that they were given no fertilizer or IRRIGATION this year. Two of the vines have grape clusters that flowered June 25th (I think this is about a week late as this 2009 is a colder spring than 2008). I kept them on the vines to check ripening dates, brix, ph. and acid and I'm expecting/hoping them to be ripe about September 25th.

The other Leon Millot and Ravat (both planted spring 2009) are irrigated and fertilized enough to ensure they don't dry out and they are also averaging about 7-8 feet of growth. However there were only a few clusters on the whole lot of LM or Ravat. The Ravat 34 clusters look very nice.

Only 5 of 8 Ortega (planted spring 2009) survived the spring and they are only about 3-4 feet tall, but they were week vines to start with.

The Agria and Regent were planted at the end of June 2009 and are between 2 and 4 feet high. I believe the difference in growth in the LM and Ravat vs the Regent and Agria is in the fertilizer as LM and Ravat got liquid stuff and the others got granular. There is one Agria plant that had a cluster on it that I was unaware of until August 9th when I saw it. I thought I had pinched off all the cluters but obviously missed this one. The cluster was already turning colour but its a bit earlier than it should be as it got started indoors and the berries are very small. I'm leaving it on anyway and will test it in September.

The Pinot Noir is going to be planted in September.

Clearing the Land / Soil Moisture


In the spring of 2008 we cleared a small area of land to use as a test spot. The land was pretty much all forested so we had to cut the trees down and remove the stumps. The land had been clear cut logged about 30 years ago so there are too many very large trees. Later in the summer we tilled up the land and put a 7 foot deer fence around the 55' x 100' test plot. The parcel of land is on a bench at about 620-640 meter elevation. That is about 180-200 meters above the Arrow Lakes. The site has decent air drainage with a 1.5/30 slope.

Here are the general coordinates if you want to find it on google earth. 49.50 north 118 west

One thing that we did at the start was take a few soil samples from the test area. We used a power auger and drilled down into the soil about 3-4 feet. In September it was pretty dry at depth but we assume this is largely from the surface plants (weeds) utilizing any moisture that falls and lower water levels in fall than in spring. The soil was tested at 6 inches and 12 inches. At 6 inches it is ph 6.5 loamy sand, very low in nitrogen but acceptable levels of other minerals and elements. At 12 inches it is ph 6.2 with virtually no nitrogen and similar levels of the other minerals and elements. The soil profile is significantly higher in organic mater for the first 4 inches then quickly degrades to sand and a few larger rocks (2"-4") at dept of about 18 inches and stays this way to a depth of 4 feet.

Soil moisture is one thing that could be a problem and we will have to check next year at different test holes how the moisture at depth is. There is generally speaking good annual precipitation and rain fall. Both Nakusp and Fauquier historically get between 800 and 900 mm of precipitation per year. In the summer Fauquier which is (4 km away) gets about 12-14 inches of rain from April 1st to September 30th. This is significant compared to the 8" that Kelowna gets in the same time period. Guess they don't call it the interior rain forest for nothing.

The Vine House

This is what we call our experimental vineyard in the west Kootenays. Actually this is what our son called our property in BC. The idea to start an experimental vineyard came about a few years back when we were talking about making our own wine. The vineyard is near the town of Edgewood, near Arrow Lakes and is at an elevation of about 2000 feet. We have done a ton of research on the area and found that historically this area was a fantastic place to grow apples, plums, pears, cherries, peaches etc. but the fruit industry died in the mid 1950's. You can still find a few old orchards within a kilometer from our site and at the same elevation. Accessibility to the large markets was poor at best and relied on shipping by boats up and down the Arrow Lakes then shipping by rail. Disease from an imported virus wiped out the cherry component of the fruit industry. When the ships stopped running the lake, that destroyed pretty much of the rest of the industry however, it was the creation of the Keenlyside Dam in Castlegar that was the nail in the coffin. The dam was completed in 1969 and flooded the valley and nearly all good farm/orchard land along the Arrow Lakes from Castlegar to Revelstoke.









Historical Reference to the Arrow Lakes Fruit Industry
www.alhs-archives.com/articles/berryboats.html

The climate in the area is hot in the summer and moderate in the winter. Historical records from Nakusp (55 km north) and Fauquier (4 km east) show a all time low of about -30 c. compared to -37 for Kelowna(AWOS) (90 km west) , Vernon (100 km north/west), and Salmon Arm. What is interesting is that these lows for Nakusp were pre-1968 (before the Keenlyside dam flooding) and since then the lowest temperature has been -23 c. at both Fauquier and Nakusp. Some of the locals claim that when the valley was flooded and the lake got bigger that the climate moderated some and eliminated the deep cold spells of winter. There may be something to this as Kelowna which is 90 km to the west (as the crow flies) has experienced its historical lowest temperatures since 1968 and has touched the -30 c mark a few times since 1968. This past winter 2008/2009 Kelowna (AWOS) again got as low -30. The lowest temperature at our site was -25 c on the same day and the lowest temperature at Nakusp was -18c. We had only one other cold day below -20 c this past winter which was -22 c in January. We also get a pile of snow and in January of 2009 and 2008 there was 3 feet of snow on the ground. The Canadian Plant Hardiness Zone map puts our location at the 5B/6A zone.

We found out that in BC the earliest ripening grapes require about 850 degree days growing of heat and about 130 frost free days. In addition, we learned that -30 c is critically cold for even the hardiest of BC grape varieties. So far we determined that if we had cold hardy varieties we'd be ok but we needed to determine if we have enough heat and frost free days. From the climate data logger at our site we found it recorded 905 degree days growing from May 1- Sept 31 of 2008 using 10 c base. Not bad for what was considered regionally as a cold summer. Add about another 30 degree days each for April and October for a year total of about 950-960 DDG. There was killing frost on May 2nd and October 9th giving us about 160 frost free days and based on extrapolations from the Fauquier historical weather data I had expect about 150-160 frost free days.
