Certainly 2016 will go down as one of the great years in chestnut history, from the perspective of new orchards, high yields and new cultivars. At the Great Lakes Expo chestnut education session, Dennis Fulbright promises to discuss the Clarksville yield trials and compare the 2016 season with results from the previous seasons. He also promises to bring people up-to-date on chestnut blight biological control efforts, the progress MSU is making on tissue culture and rooted cuttings, and Asian chestnut gall wasp spread. Bring your friends and potential orchardists as we will focus on our continued effort in establishing more orchards and a critical mass of chestnut farms that will cement Michigan’s role as the Number 1 chestnut state.

Have you seen the giant ‘Bouche de Betizac’ nuts? New customers are being found and reliance on streamlined methods for disbursing the product are being used. Two new chestnut bottled beers premiered in 2016. Both Chestnut Head from ROAK in Royal Oak, Michigan and King Chestnut, Tennessee Brew Works, Nashville, Tennessee (released on November 10th) are being distributed to stores. These beers go along with the 10th anniversary of Fuego del Otoño production and sales from our longtime friend Jolly Pumpkin Artisan Ales. They also produced 2 new chestnut beers; a chestnut IPA and their flagship BAM beer now with chestnuts. These new beers supplement their gluten-free chestnut beer which won the gold medal at the Denver All American Beer Festival in 2010.

Chestnut Orchard Solutions will be looking into various ways to obtain new chestnut harvesters so that more orchards can be harvested in a more timely manner around the state with a simple application that you can find on this website in September, 2017.

There will be no chestnut booth this year, but Forrest Keeling Nursery will be present and staffed with people willing to help you with your chestnut questions. We will see you at the education session or at the Forrest Keeling Nursery booth.

COS Finishes Record Harvest!!!!

With over 70,000 pounds to its credit, Chestnut Orchard Solutions finished its first harvest as a start-up company. Using the only self-propelled chestnut harvester and cleaner in North America, the FACMA Cimini 180s, well over 65,000 pounds were harvested from orchards around the state. Operators of the FACMA harvester included Dr. Josh Springer and Dr. Carmen Medina. Its good to be back in the lab working on the biological control of chestnut blight, tissue culture, and rooted cuttings of chestnut. Next up, the events surrounding the Great Lakes Expo education session Tuesday, December 6, at 9:00 am (DeVoss Place, Grand Rapids)


At this time, COS team members want to stop and say thanks to those who made this possible.


Our clients, first and foremost, we need to thank you, as you were the ones who trusted us to get to your orchards and harvest as many nuts as possible. It was a somewhat difficult harvest to manage as orchards in the southern tier counties were dropping nuts when the central and northern tier county’s were dropping. We made the trip from near the Indiana state line to the 45th parallel, and back to Clarksville, more than once. So, for the three of us at COS, thank you for your trust, your help and your encouragement.


FACMA, who makes the best chestnut harvesters and who has supported our efforts in Michigan for the past several years. This year, our little machine harvested the amount that had been close to the previous state record last year.


Michigan State University, who worked with COS to help make this harvest possible.


Mario Mandujano, who taught us how to use the harvester, told us its secrets, and taught us to care for it; he really worked behind the scenes to make this commercial harvest possible in everyway. Thank you Mario for trusting us to do it right.


Jim Blaha, an engineer who worked on the machine, helping to prepare it for its biggest harvest.


Mark Stites (Repairs and More, LLC), Elk Rapids, who answered a call for help one day when a problem needed diagnosing and fixing. We were a long way from home. It ended up being a blown fuse, but how did we know? Thanks, Mark. Need help in Elk Rapids area? Call 231-360-9070 and ask for Mark.


Don Guateri, who put things in order with the orchards up north and found us Mark Stites when we were far from home. Don, you stuck with us when we were on the verge.


Gary Zehr and Dr. Dan Guyer, both who made these weeks possible with their past and current support of our mechanical needs in all aspects of chestnut work.


Without these organizations and people, the three team members of COS would not have been able to commercially harvest approximately 30% of the state’s cooperative totals. We hope to have more machines in the orchards next year.


With burs full of chestnuts and trees dropping burs, COS attempted to harvest as many chestnuts as possible, by Nut Wizard and FACMA harvester.


We ran chestnuts back to Clarksville as often as possible. Here a ton of chestnuts are ready to leave a farm at the 45th parallel after dark for delivery to CGI the next morning.


Big horse or small trees. Competition for the chestnuts was increasing by the day.


Remember when we asked you to prune your trees and you asked, “Why?”


Carmen stops the harvester and assesses the fix before allowing  the harvester to move forward again.

Chestnut Orchard Solutions busy helping growers establish chestnut orchards and harvest nuts

COS Helping to Harvest State’s Chestnuts

Chestnut Orchard Solutions has been contracted by several chestnut orchardists across the lower peninsula in Michigan to help harvest chestnuts. For the second year, COS will choose between hand or machine harvesting based on time of nut drop, weather conditions, size of orchard, age of trees and potential of yield. It looks as if nuts will begin dropping in the southern region of the state around October 3. Of course, some cultivars like ‘Labor Day’ have already dropped at this time in many of the southern and central counties of the state. As chestnuts are selling from $1.50 to $2.80 in the wholesale market, many growers are finding that they are more than willing to pick up the nuts. This is the final aspect of nut farming. After working hard to establish the orchards and care for the orchards, harvesting and marketing are the last two steps to provide that feeling of accomplishment, to provide a healthy food for consumers and extra cash for the farm and family.

Congratulations To Our Clients Who Purchased Trees!

The COS team wishes good luck and good growing to our COS clients who received trees and started or expanded their chestnut orchards in 2016. The COS team reminds you that we are here to help you through the process of making good decisions based on best practice management. We can also physically work with your orchard to help you achieve your goals. COS clients who would normally be worried about rain are beginning to wonder it the rain will stop. Don’t over water as there has been plenty of water for this time of year. Prepare for next year and make sure the trees don’t suffer in an extended, hot, dry summer next year. Our clients should never hesitate to email or call to get the most up-to-date information on successful tree establishment. Our goal is to help you establish a successful orchard.

Remember, the COS philosophy is that the most important years for a successful orchard are the early years. Therefore, remember, to follow these minimum guidelines for a successful planting and orchard:

  • Keep the young trees staked.
  • Trees survive best when planted into well drained sandy or clay loam soils.
  • pH of the soil should be below and kept below 6.2.
  • Use no fertilizer at planting time.
  • Have a plan to repel deer.
  • Add mouse guards.
  • Paint trees to the top with 50% white latex (diluted with water) to prevent sun scald.


Remember, these are the minimum guidelines. We remind you that we can provide more guidelines for successful planting, orchard management, harvesting, and/or act as consultants for all aspects of chestnut orchard and tree care when you call us for help.


This orchard plan was laid out by working with the basic plan suggested by Michigan State University chestnut researchers, COS team members and the grower.

FKN Chestnut Distribution Better Organized in 2016

Most of those picking up trees at the MSU Clarksville Research Center would agree that the experience was still not perfect but better organized and much faster than in 2015 even though more than twice as many trees (greater than 4,000 trees) were distributed. By Saturday evening 90 percent of the trees had found their owners and were being taken to their new homes in Michigan. Two semi trucks and trailers pulled into Clarksville on Thursday, September 15 and the trees were off-loaded into organized groups of chaos. Cultivars representing ‘Labor Day’, ‘Colossal’, ‘Bouche de Betizac’, ‘Precoce Migoule’, ‘Marsol’, ‘Marigoule’, ‘Maraval’, ‘Benton Harbor’, ‘Peach’, ‘Gideon’, ‘Amy’, ‘Qing’, ‘Eaton’ and ‘Sleeping Giant’ were pooled together then quickly moved into place ready for the pick up by 35 different growers. Many of the trees hitched a ride with COS trucks that took them to waiting growers representing farms in southern, central, and northern Michigan. On Friday, Sept. 16th, growers began arriving and loading their trees, checking their lists and driving home with new trees in tow.  A COS planting guide was attached to each order.

Some chestnut orchards in Michigan require mechanical harvest as this machine (above) can harvest almost 4 tons of chestnuts in one day. If you don’t require the mechanical harvester, we can still pick them up with the Nut Wizard (below).
