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?”

COS More Than Halfway Through Record Harvest

It’s been a nearly perfect chestnut growing season from winter to spring to summer and now fall. COS team members are out in southwest Michigan, central regions and northwest regions machine and hand-harvesting chestnuts.  The increased harvest from 2015 to 2016 represents several aspects of the trees: After the easy winter of 2015/16, the trees are repairing damage after the two difficult winters of 2013/14 and 2014/15; a lack of any spring frost in the state, the warm and dry conditions during pollination, just enough rain at the appropriate times, and grower interest in the developing chestnut industry in Michigan.  While Michigan’s overall yields never decreased over the past 3 years, they did not increase proportionally to the age of the trees in the last two seasons. This year is a different story. In 2016, it seems the yield has caught up with the age of the trees.  Most chestnut trees are producing well. Orchards that had produced 12,000 to 15,000 pounds are producing over 20,000 pounds or more in 2016.

So far, halfway through the harvest, the COS team has harvested about 40,000 pounds of nuts representing several orchards.  We will continue to work hard until the harvest season is over.  An interesting event is happening with harvest this year.  It seems like most of the burs are open and nuts have dropped, but there are still many burs on the trees that have not opened yet and the second half of the harvest season will see these nuts drop.  Probably Michigan, taken as whole, will see more than 100 tons of chestnuts for the first time.

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.


Two semi trucks loaded with Forrest Keeling Nursery chestnut trees arrived at the MSU Clarksville Research Center for distribution by Chestnut Orchard Solutions on September 15.

Chestnut Trees Will Be Available Friday, September 16

COS Will Again Help FKN with Orders

September 17th Field Trip Canceled


The plan to hold a field trip at the Clarksville Research Center (CRC) has been canceled due to the early arrival of the Forrest Keeling Nursery (FKN) grafted chestnut trees. Chestnut Orchard Solutions (COS) board members met with FKN in August to help secure the early arrival of the FKN-grafted chestnut trees for Friday, September 16, beginning at noon. This early arrival will benefit the chestnut industry in Michigan since nut harvest for many chestnut growers will be extra-large this year. The more separation between tree arrival and harvest will provide more time for both planting and harvesting. The venue for chestnut tree pick up will be the same as last year: COS member Carmen Medina of COS will be at the MSU Clarksville Research Center, 9302 Portland Road, Clarksville, MI. The orders will be arranged by grower. There is a chance that some extra trees will be available and growers may pay for and take home extra trees until they run out. Orders will be distributed continuously from noon Friday, Sept. 16th to 4:00 pm Sunday, Sept. 18th. After that, please call Carmen at 616-666-2004 to schedule your pick up.

Hours for pick up—

Friday, Sept. 16th, noon to 5:00

Saturday, Sept. 17th, 8:00 to 5:00

Sunday, Sept. 18th, 10:00 to 4:00

After this, call Carmen to make arrangements for pick up at 616-666-2004.


COS will play a major role in distributing the trees at the CRC. If you want to have your trees delivered by truck to your farm, COS can deliver the trees to your orchard. Contact us so we can get you on our growing deliveries list! We can also provide planting assistance! Call 517.643.2875 or email for more information.

Field Trip to New Era Chestnut Enlightening


COS Field Trip to Chestnut Orchard in New Era, Michigan

On July 9th, the Chestnut Orchard Solutions field trip to the New Era Chestnuts orchard of Roger Blackwell and Doug June showed off the superior trees that orchard founder, the late Don Welling planted. We emphasized that the orchard was heading down hill as Don had not done too much to help the trees. This orchard was established without irrigation and some of the trees really struggled when they were younger. About 250 trees planted in 2000, 2002 and again in 2004 dominate the location.

IMG_0352Made up primarily of Colossal and Nevada, this is the last orchard in the state where the winter-sensitive Nevada still does the majority of the pollinizing. Planting Nevada today is not suggested or encouraged, but it worked at this location.   Roger and Doug also have a Fraser fir plantation that they care for. Overall, Roger and Doug had to begin a serious campaign of fertilizing, pest control and pruning. Because of the earlier use of Sevin insecticide, they began using dormant oils to get control of the mites that had built up. Then the leaf hopper and Japanese beetle problems arrived, but all this is now managed with general management plan.

New plantings from Forrest Keeling starting in 2012 are located between the Fraser fir and the older Colossal trees. The trees are now under irrigation.


We discussed the yields and the amount of return they have received each year. The orchard looked fantastic and Josh Springer showed the prowess of his chestnut blight management in the orchard. Rarely do any trees die of blight anymore.

COS thanks our client Roger Blackwell and Doug June for allowing us to showcase their orchard for a delightful afternoon.

Fourth Chestnut Orchard Visit led by COS

Third Field Trip led by COS

Mark your calendar- June 25, Third Field Trip!

What will we see? A nearly 3 acre site that was previously a forest of non-native trees that has been removed to be planted with a chestnut orchard. You’ll see the result of hard work to remove the trees, prep the land, plant the chestnuts, and protect them so they succeed in the future. Irrigation is in the midst of being installed as is electricity. Come prepared to ask questions and discuss how to establish a chestnut orchard.

Meet at 1pm at the Meijer in Birch Run, Michigan (I-75 exit 136) 9515 Birch Run Road at the south side of the building near the greenhouse. From there trip participants can carpool or caravan to the orchard (about 5 miles east).


Snacks and water will be provided.

Please RSVP to if you plan to attend.

Second COS field trip—June 11

The next COS field trip June 11—Asian Chestnut Gall Wasp (ACGW) infestation will be the subject of our upcoming field trip.

Meeting time will be held starting at 1:00 pm at the Michigan State University Southwest Michigan Research and Extension Center in Benton Harbor, Michigan.  We will meet in the auditorium at the main administration building where restroom facilities are located. The meeting will cover the life cycle of the pest, the biological controls, and how the various cultivars will probably react to the infestation.  See below for directions to the Research Center.

Then about 2:00, we will head to the chestnut plots where we will see first hand the last 2 years infestations and the brand new galls just now developing. The meeting should be over at about 3:00.

Snacks and water will be available.

As usual, clients and their immediate family will be admitted to this field trip free of charge. Non-clients will be assessed a fee of $25.

This field trip will be led by Dennis Fulbright and Josh Springer.

First COS Field Trip A Success——Preparations Underway For 2nd Field Trip —June 11—To See Gall Wasp

Participants in COS’s first field trip for 2016 are not deterred by the unseasonable weather and strike out across the field to view other parts of the Jackson-based Alan Brent orchard.


Nearly all of the cultivars made it through the fall planting which took place before the 2014/15 record breaking Michigan frigid winter.  Now beginning to break bud after the relatively mild 2015/16 winter, most of the young trees are growing from the terminal buds and have missed the potential of a mid-May frost.   The future appears bright for the 2016 growing season.




Mark your calendar!  Next COS’s field trip, June 11—Benton Harbor, Michigan. Topic to be discussed: Asian Chestnut Gall Wasp. Details on this trip will be posted by June 1.
