Northern Grapes Webinar Series - Check it out!

Thursday, October 16, 2014

Hi folks,

I hope harvest is going well and I'm sure it's pretty busy on the crushing room floor these days!  I just wanted to pass along some information for the next series of Northern Grape Webinars that start on November 20th.  If you haven't already checked these out, it's a great way to hear the latest research and information without ever having to leave home (it's the only 'conference' you'll be able to attend in your PJ's).  You can sign up and join each presentation 'live' online or you can check out their website for a list of all the archived presentations they've given over the years.  If you join live, you have an opportunity to ask questions of the presenters and other 'audience' members!

You can check out information on the Northern Grapes Project here. You will find information on their research objectives and their monthly newsletters (there's some timely information on there right now regarding wine deacidification) as well as a link to their archived webinars and a spot to sign up to join in this years webinar series! 

Here's a peek at their upcoming webinar schedule!   Cheers, Rachael

Fertility - Time to Tissue Test

Thursday, July 31, 2014

Hi Folks,

First off, thanks to everyone who came out to our first Vineyard Walk of the season at Planters Ridge - and thanks to John and Lisa for having us! 

I hear from a lot of people around this time of year wondering what (if anything) they should be fertilizing with in their vineyards.  While soil tests do a great job of telling us what's in the soil, it doesn't always translate into what the plant is able to take up!  I am a strong promoter of tissue testing with any perennial fruit crop (and really even many longer season annuals).  It's just a really good way of determining what the plant is able to take up from the soil and what you might need to look at supplementing! 

Generally with grapes, tissue testing is done during Bloom or at Veraison!  Since we are quickly approaching Veraison, I thought it might be timely to post some info on taking your tissue tests!

Sample each variety separately and if you have blocks of the same variety in different areas, it might be best to treat them as separate samples also. 

You can find information on what plant part to sample on the NS Analytical Lab Website  and you can click here to download a copy of the sample submission form. 

When you get your results back, it's a good idea to compare them against 'normal' ranges (this one is from the Midwest Grape Guide)

Suggested "Normal" Ranges of Nutrients from Grape Leaf Petioles* Nutrient
Normal Range
Nitrogen (N)
0.9 – 1.3 %
Phosphorus (P)
0.16 – 0.29 %
Potassium (K)
1.5 – 2.5 %
Calcium (Ca)
1.2 – 1.8 %
Magnesium (Mg)
0.26 – 0.45 %
Manganese (Mn)
31 – 150 ppm
Iron (Fe)
31 – 50 ppm
Copper (Cu)
5 – 15 ppm
Boron (B)
25 – 50 ppm
Zinc (Zn)
30 – 50 ppm

If your values are significantly higher or lower than these - please feel free to give me a call to discuss! 

Finally please mark Thursday August 21st on your Calendar for our second vineyard walk of the season.  Details will be announced on location soon!  Stay tuned to the blog and our facebook page for details.

New Pest Management Guide is Online and 1st Vineyard Walk - July 17th!

Tuesday, June 24, 2014

Hi Folks,

Happy Summer!!!! It's been a long time coming, so hopefully it is now officially here to stay!

I've been hearing some reports of winter kill this year, not surprising given the cold temperatures - also some reports of deer, mouse and vole damage which again is to be expected in a year with so much snow cover!

The new version of the Grape Crop Protection Guide is now online! Click Here! You'll notice some changes - we have now included a section on Weed Management - please have a look if you are wondering which herbicide to choose!

Weed control is extremely important when getting your vines established - the area within the row should be kept as clean as possible to reduce competition for nutrients and water! In case you missed it, The Northern Grapes Project hosted a great webinar on Vineyard Floor Management last winter! And you can check out their archives for a number of great webinars!

Mark your Calendars - Our Vineyard Walks will be starting July 17th, 2014 (6pm start!) - Our first one will be held at Planters Ridge Winery (1441 Church St, Port Williams) - thanks to John McLarty and Lisa Law for agreeing to host! You can check out their webpage for more details on the winery and vineyard!

Under Trellis Management Webinar

Hi Folks,   Hope your winter is going well and I'm sure everyone is anxious to get out and start checking for winter damage after Dr. Helen Fishers' talk at the GGANS AGM on the weekend!  I mentioned that I would post a link to our factsheet on how to monitor for Spotted Wing Drosophila - here it is!  Please send me a message if you have any questions... 

I also wanted to let you know about this great webinar that's coming up next week on Under Trellis Management.  I get lots of questions from growers on what the best strategy is for the area beneath your vines... we are lucky to be able to take advantage of hearing these excellent speakers without having to leave the comfort of home!   Please see below for webinar details and how to register!!
