Dormancy in the Vineyard

Dormancy is a crucial phase in the vineyard, allowing vines to rest, conserve energy, and prepare for the next growing season. Proper management during this time, from pruning to soil care, can directly impact grape quality and yield. Learn more about the importance of dormancy and how it sets the stage for a successful harvest.

Fall Planting – The Secret to Successful Replants

Planting Super Pots in the fall? Great choice! We've seen stronger results compared to spring planting.

  • Dig Deep: A 15" x 15" hole clears out competitive roots and sets vines up for success.
  • Amend & Plant: Add compost, and let winter rains settle the soil—no need to compact by foot.
  • Irrigate as Needed: 1.2 inches of rain is ideal to hydrate roots. If rain isn’t in the forecast, give the vines a drink!

While this method boosts growth, be mindful of frost risk based on your site.

Harvest Wishes & Tips from Guillaume!

It's harvest time!

A busy season when all of our hard work comes to fruition. Our team at Guillaume wishes you and your team the best of luck this harvest season.

As grapes reach full maturity (and as time permits), this is the perfect time to reflect on the season. It's essential to assess the health and quality of the grapes while considering their potential for wine production. Any virus issues in the vineyard should be addressed by rogueing and removing infected material. These findings can guide future projects, helping to make decisions about rootstock choices or adding new clones for variation and blending potential.

Dormancy preparations, which are often overlooked, should also be considered. If you have irrigation, now is the time to give the vines one last drink of water. A final spray to reduce mildew pressure before leaf senescence may also be beneficial. This practice, although new to me, is promoted to allow the vines to capture all available nutrients from the senescing leaves, storing reserves for the next season.



Guillaume's Estimated Bareroot List is now available! Reach out for the current list by emailing or calling Dylan at (530) 379-5007 or dylan@guillaumenursery.com.

At the heart of every great wine is exceptional grape quality, a topic we never stop discussing! In a recent conversation with Jean Hoefliger and Ryan Pass, we dove into the importance of yeast selection, with a key takeaway: everything comes back to the quality of the grapes. Be sure to check out the post for more insights and tips on maximizing your vineyard’s potential. Read Here

We hope you take time to enjoy this harvest season! While it’s a busy period, remember to savor that extra cup of coffee and celebrate the fruits of your labor with friends, family, and loved ones. Harvest is about both hard work and the joy of abundance, so take a moment to reflect on the season’s successes. At Guillaume, we deeply value the trust we’ve built with you over the years, and your dedication to quality inspires us to continue supplying your vineyard with premium vine material. We’re grateful for your partnership and look forward to supporting you in many harvests to come. As you move forward with the harvest, remember that our team is always here for you. Whether you need advice, updated lists, or simply a helping hand, don’t hesitate to reach out. The Guillaume Family appreciates your ongoing support, and we look forward to a bright future of collaboration and growth. Together, let’s make every season a success!

Insights for a Successful Planting

Hey growers!

We hope everyone is doing well and maintaining vigor despite these heat spikes! Here at Guillaume, we're diligently tending to the young nursery blocks. Take-rates are looking fantastic, and many young vines have successfully found their way to new vineyard block homes.

We've been out in the field meeting with growers and are always happy to arrange a time for an on-site visit or phone call to discuss any questions you might have. On a recent visit, we met with a grower who achieved an impressive 99.4% take rate with their planting.

Several diligent decisions made throughout the planting process have contributed to this success.

Proper weed management with cultivation helps gives vines space to grow

  • This order was placed in November 2022 for bare-root vines that were delivered on April 1, 2024. The early order ensured the availability of the desired vine material and gave the grower ample time to prepare the site.
  • Planting on schedule allowed the vines to benefit from cool spring weather, which helped them acclimate, explore the soil profile with feeder roots, and establish themselves. As the weather warmed, the vines were in perfect condition to thrive with the season.

  • Fertilizer was introduced a few weeks after planting, depending on the existing soil nutrition and any amendments added prior to planting. Please feel free to ask any questions or reach out to your fertilizer supplier for guidance!
  • The grower has been meticulous with water, providing just the right amount and includes proper weed control, keeping the plants free of any undesirable competition. Regular watering kept the young vines moist and encouraged growth, as too much or too little water at a very young stage can seriously stunt the vines.

One crucial aspect of this diligent planting project is the attention to detail. Their oversight confirmed proper planting height, proper trellising, and vine cartons sunk into the ground to prevent the "chimney effect". Great care was taken to ensure that soft, loose soil was used to fill in around the vines.  Often, we see planting crews using dirt clods from shovel scoops to fill the planting holes, which can cause air pockets around the vines and stunt root growth by preventing proper soil contact.

Using soft, loose soil fills these air gaps, and adequate irrigation immediately after planting fills any remaining gaps. Irrigation is sufficient for this purpose, and neither bare-root nor potted vines need to be stepped on or stomped to be set into the soil.

As always, we are available to address any questions or concerns, reply to this email or contact Dylan at (530) 379-5007.

Guillaume Grapevine Nursery

Planting Guidelines & Replants

Happy Spring!

Planting season is here, and many are already getting their vines in the ground. If you haven't gotten yours yet, don't worry! We have plenty of bareroot and potted vines still available.

Potted vines are great for replanting, at any time during the year. Bareroot vines work well for replanting or vineyard (re)development - optimal bareroot planting window before mid-June. Our grafting season ends soon, so if you need vines for 2025, order now!

Here we share some quick tips on receiving and planting vines. Please reach out with any questions about your new vines and their success!

Acclimating the Vines (March-May):

  • It's crucial to allow the vines to acclimate properly to their new environment for good regrowth.
  • We shared acclimation tips in our last newsletter from February (Delivery & Acclimation) -- please reach out if you'd like the specifics.

Vine Planting:

  • Dig a hole of adequate depth (at least 15 inches) ensuring that the roots won't bend to avoid J-rooting and that the grafting point of the vine will be positioned between 1 to 2 inches above the soil level.
  • Vine roots can be trimmed to 2-3 inches, as preferred, to mitigate J rooting and encourage rooting.
  • When placing the vine in the hole, take care not to bend the roots and ensure that there are no air pockets when filling the hole with soil.

After planting, it's recommended to water each plant with 3 gallons of water to help establish them in their new surroundings.


Carton Protection:

  • If you opt for using protection, be cautious not to create a "Greenhouse Effect," especially in hot weather conditions, as poor air ventilation inside the carton can lead to adverse effects.
  • Ensure that the top of the protection allows for adequate air circulation by adjusting its openness or closure accordingly.

Fertilizer Application:

  • When using fertilizer, never apply it directly on or near the roots as this can potentially damage them or the vines.
  • Instead, apply the fertilizer at a safe distance from the roots to promote healthy growth without risking harm.

In addition to these points, maintaining proper irrigation, pruning, and monitoring for pests and diseases are also essential practices for nurturing healthy vine growth. Regular observation and adjustment of care practices based on the specific needs of the vines and environmental conditions can contribute significantly to their overall health and productivity.

Acclimating bareroot vines is a crucial step to ensure their successful establishment when planted. Here's a step-by-step guide on acclimating bareroot vines and root pruning: 

1. Upon Arrival:

  • Inspect the bareroot vines upon arrival to ensure they are in good condition.
  • If the vines cannot be planted immediately (depending on when they are received), they should either be acclimated or kept in cold storage to prevent drying out.

2. Acclimation Process:

  • Prepare a container, such as a ½ ton grape bin, filled with water.
  • Place the bareroot vines in the container, ensuring that the graft union (the point where the scion is attached to the rootstock) is above the waterline. This helps prevent disease or rot issues at the graft union.
  • Allow the roots to soak in water for 24-48 hours. This helps rehydrate the roots and prepares them for planting.
  • After the initial soak, give the roots a period of 8-12 hours without water. This allows the roots to breathe and stimulates aeration.
  • Subsequently, add water again and repeat the process until the vines are ready to be planted. This intermittent drying and soaking help the roots adjust to the new environment.

3. Root Pruning:

  • Before planting, consider root pruning if the roots are excessively long. Root trimming to 2in. has shown to achieve the best results. Trim any broken or unhealthy roots, but be cautious not to remove too much healthy root material.
  • Root pruning helps stimulate the growth of new, healthy roots and encourages the development of a well-branched root system, promoting better nutrient and water absorption.

4. Planting:

  • Once acclimated and, if necessary, root-pruned, the bareroot vines are ready for planting.
  • Dig a hole deep and wide enough to accommodate the roots without bending or crowding.
  • Place the vine in the hole, spreading the roots evenly, and cover them with soil. Ensure that the graft union is positioned above the soil line.
  • Water the newly planted vines thoroughly to settle the soil and eliminate air pockets.

5. Post-Planting Care:

  • Provide adequate water and monitor the vines closely during the initial period after planting.
  • Mulch around the base of the vines to retain moisture and suppress weed growth.
  • Follow any additional care instructions provided by the nursery or supplier.

By following these steps, you enhance the chances of successful establishment and growth of bareroot vines in their new environment.

The Time to Order Vines Is Now!

Guillaume is finalizing our 2023 production season at the nursery -- bareroot vines will be dug up from our nursery fields for delivery in February. New vines will be grafted as Super Pots for delivery in Spring. Grafting, callousing and shade houses will be full of new vines by early next year! 

Bareroot Vines: Tips & Tricks

  • Bareroot vines are an excellent choice for new vineyard establishment to promote strong, even growth.
  • Ideal planting season is February through April depending on local climates.
  • Bareroot vines will be harvested in November, graded and ready to ship in February.
  • Root trimming to 2 inches has shown to promote new root growth at planting - Guillaume can trim your roots before shipment.
  • Ask about our Inventory List - Bareroot Vines are Available!
  • Request delivery as soon as possible to get on our delivery schedule.

Fall Planting -- The Secret to Replants

  • For those replanting in the fall. Great idea! We have seen great results when planting Super Pots in the fall vs. same vines planted in the spring.
  • The secret is to dig a bigger than needed hole to remove competitive roots. Our suggestion is 15" x 15". The labor and time will pay off the following season when the vine can be trained to the fruiting wire.
  • Compost / amend soil and plant. Winter rains will fill air pockets, no need to step on vines to compact soil. Irrigation may be necessary to keep new vines hydrated; 1.2in. Of rain should be sufficient to wet rootzone of newly planted vines. If there’s no rain in the forecast give the new vines a drink!
  • This method yields great results however, frost risk should be considered site by site.

About Dormant Bare-Root Vines:

Dormant bare-root vines are planted and grown in a nursery field during the whole growing season, then dug out in fall-winter after the vines have entered dormancy. After being graded they are stored in cold storage until delivery. Dormant vines are produced at standard size (12-inch rootstock).

When to Place Your Order:

  • You can place your orders for dormant vines until the end of March, and we'll have them ready for delivery the following year.
  • Additionally, we maintain a year-round inventory of vines ready for planting.
  • Feel free to get in touch with us for the most current list of available combinations and quantities by requesting our latest availability list.

When to plant?

  • Typically, the ideal planting season for dormant vines spans from March to June. However, winter planting is also an option, albeit less common.
  • Keep in mind that dormant vines usually require some acclimation before planting, and their roots may need to be trimmed, as they are usually delivered with 6-inch-long roots. Don't hesitate to reach out to us for our planting guidelines.

What are the advantages of dormant bare-root vines?

  • Dormant vines are generally more robust than potted vines because they were grown for a full season in a field.
  • They can be planted earlier in the season, which allows stronger growth the year of planting.
  • They are easier to ship and handle than potted vines, also easier to plant.

About

The Guillaume family has been grafting vines in Charcenne, France, for more than a century. Our knowledge and experience has been passed on from one generation to the next as our company has continued to evolve and develop, earning a name and ongoing recognition in the worldwide grapevine industry. 

 

The origin of the French nursery goes back to a time when the Franche-Comté region had to rebuild its vineyard after the Phylloxera crisis. In 1895, Albert Guillaume started to graft vines and set up a nursery that sold planting material in several wine-producing regions of France. At the end of the development of hybrids in 1954, Henri Guillaume assumed control of the business and had an active part in the reconstruction of the Bourgogne and Champagne Vineyards. From 1983 up to until the present time, his son Pierre-Marie Guillaume has continued to expand and develop the company, giving it an international scale and focusing on research and genetic selection. 

 

After expanding to South America in the year 2000, Guillaume Company set up a subsidiary in the United States in 2008, Guillaume Grapevine Nursery, in order to work with North American grape growers and provide top-quality material as well as sharing its well-recognized experience.
