The Farm Log for the Year 2011
Considering what a bad growing year 2010 was we now move into 2011 hopeful
and wiser. We now know chestnut producers can loose most if not all their
harvest for any one year. Had chestnut producing been our only source of
income we would have lost everything including our home. Aside from not having
any income our normal expenses for operating the orchard continued. These
expenses are such things as equipment repairs, fuel, replacement of hoses and
watering sprinklers, and many other expenses. No wonder why there are so few
commercial chestnut producers who derive all their income from producing
chestnuts.
Goals for this year are focused on increasing efficiencies and helping our
customers enjoy their chestnuts more through continued research and development
of new chestnut focused recipes. So our goals for 2011 are:
1. Increasing the survival rate of chestnut tree seedlings to better
than 90 percent.
2. Formalize the recipe development with taste testing panels and well
documented recipes that are easy to prepare.
3. Add 4 more acres of chestnut trees to the farm.

Spring
The new chestnut trees from chestnuts harvested last fall are all up and
growing so fast, some are already 9 inches tall (Late April). Seeing all this
new life spring up from the soils is such a sight to be seen. These new trees
are already being spoken for with lots of folks calling in and picking out
just the right trees for their ground. Precoce Migoule is the most requested
chestnut cultivar so far this year. If a nice long storage life, that is more
than 10 days in the fridge, then consider the Bisalta #3 chestnut cultivar.
The chestnuts from this tree were used in a storage test we conducted this past
fall and winter. We were able to store the chestnuts for a full 10 weeks in a
sealed standard ziplock plastic bag. The bag was opened ever 2 weeks for
inspection.
Aside from taking care of the new trees, all 3000 of them, we have regular
orchard maintenance to do like, mowing grass, weed control, replacing dead
trees, fertilizing trees, and preparing for the fall harvest. Preparing for the
fall harvest starts in the spring because there are a lot of resources needed
during the harvest and distribution of the chestnuts. From little things like
mesh bag closure, shipping boxes, and computer automation for order processing.
Then there are the big things like formalizing the fall marketing plan for the
harvested chestnuts. So if there is a time we feel we are caught up with the
things that need to be done, the feeling is just ignoring the many chores we
just have not put high enough on the priority list to be noticed.
Summer
So far the weather during most of the growing season has been 5 - 10 degrees F
below normal. The cooler temps appear to effect the growth rates of the
chestnut trees. Typically, the chestnut trees grow 3 or more feet a year. This
year we have very few trees that have grown more than 18 inchest so far, and
most of this years grow is now done (last week of August). The good news is
even though the temps have been below normal and rainfall way above normal, the
chestnut trees have an excellent nut set. The harvest season is only about 4 to
6 weeks away and we still have a many chores to accomplish before it arrives.
In the back rooms of the chestnut business we find lots of dicussion about how
to put together a chestnut orchard that produces the largest chestnut with the
greatest tons per acre. The chestnut tree of choice for size and production is
the Colossal cultivar. For people who just want great tasting chestnuts from
their chestnut trees, they need to set aside size and tons per acre.
If we look at apples as an example, the Wolf River apple is widely accepted as
apple variety that produces one of the largest apples. For those people who
have one of these apple trees you will find it is not their only apple tree,
because the apples are not a great apple when compared to other apples grown.
In the commercial apple tree business nobody grows the Wolf River apple for
commercial sales. There are some great apples available to us including Fuji,
Pink Lady, Honeycrisp, BelMac, Jonagold, and many others. Now lets focus back
to the chestnut trees and list a few of the great tasting nuts without the
focus on size on tons per acre. At the top of the list are Marrone de Marradi,
Marrone di Comballe, Marigoule, Regis Montis, and Szego. All of these
chestnuts have common genes from the European chestnut trees (c. sativa), some
pure c. sativa, and some hybrids with c. crenata or c. mollissima. One other
thing these chestnut trees have in common is they will never come close to
producing chestnuts on the commercial scale like a Colossal does. The Colossal
makes a good choice for commercial growers because most consumers want very
large chestnuts, and that is what the Colossal chestnut cultivar delivers.
If you go looking for one of these great tasting chestnut trees in a local
nursery your not going to find it. There just is not enough demand for chestnut
trees for the retailers to stock them. Over the past 20 years the yard sizes of
the average new home has gotten much smaller. Only small trees fit in these
small yards. The apple nurseries have dwarfing apple trees that fit nicely in
these small yards. A chestnut tree planted in the back yard after 20 years
would be shared with as many as 4 neighbors. Now that is a good neighbor, well
maybe not that nice if you have to pick up the leafs and dropped branches and
you do not find chestnuts as appealing as the person who has the trees in their
yard. So chestnut trees for the most part are banned from local retail
nurseries. Mail order or online is your only choice. Most online nurseries also
do not sell chestnut trees. Your only option for finding chestnut trees that
produce great tasting chestnuts is online speciality nurseries. The good news
for this year is we now have all these great tasting chestnut cultivars growing
and next year we will be able to provide some of these to the public for sale.
Late Fall
Looking back at this year's growing season and summarizing it in just a few
words, these words would be "Poor, poor, and can it get any worse?" Sounds
bad doesn't it? Our harvest ended up being only about 400 lbs, 15 percent of
what was expected using a mathematical model we are developing to forecast
the harvest. Seems like this fancy forecasting model needs some big tweaks
to correct for this years miss. More on the forecast model and its errors
later.
It is time to start thanking our customers. This year more than any past
year every customer had to wait almost 3 extra weeks before we were able
to ship fresh chestnuts. The chestnut harvest was nearly 3 weeks late this
year. We would normally see our first chestnuts fall around the 22nd of
September. This year the first chestnuts fell about the 10th of October.
We continued to harvest all the way up to the first week in November. The
focus here can not be entirely on the chestnut harvest. We also produce
grafted chestnut trees. Some of those customers have been waiting for over
a year for their trees. These are truly very patient people. For most of them
their wait is almost over. We will start shipping trees the first full week
in December and continuing until March.
Now, back to the issues with the chestnut harvest forecasting mathematical
model. The model fell to its knees this year because it failed to identify
chestnuts that never developed kernels. Chestnut burrs were sampled in the
months of August and September to examine the developing nuts. What was
observed and what the harvest delivered did not match. The model uses the
assumption that about 75 percent of the burrs deliver 3 nuts. The remaining
25 percent deliver 2 nuts. In a simple way, count the number of burrs on the
average tree (actually about 5% of the average trees in the orchard),
multiply by the number of trees in the orchard, then apply the 75% having
three nuts and 25% having 2 nuts, then dividing by the number of nuts it
takes to make a pound of nuts. Using this model the orchard we have should
have produces about 3000 lbs of chestnuts this year. What needs to be tweaked
in the model to get a more accurate forecast? The model will need to have
some pictures added so the evaluation of the chestnut burrs and nuts provides
good guidance to the evaluator for determining if a nut is properly
developing or not. This next year pictures will be taken and documented so
the model.
