Northern Nut Growers Association Report of the Proceedings at the 41st Annual Meeting Part 33

Up until last year, chestnut seed was stratified in perforated cans in the open ground with fairly good results. Last fall, we tried the method used and described by Dr. Crane and Dr. McKay in the 1946 report of this a.s.sociation. Crimp top cans were used with nail holes in the top and bottom. Instead of using regular storage facilities, the cans were stored in a concrete block storage pit built below the floor of the garage. This proved very successful. Not only were the nuts in excellent condition for eating in the spring, sweet and of good flavor, but a much larger percentage of the seed germinated. This storage pit also serves to hold trees dormant and in good planting condition from digging time in March until early June.

Last year, many young seedlings were lost during the dry weather and hand weeding between the trees was next to impossible. This spring, we tried the method of planting used and described by Mr. Sam Hemming in the 1947 report of this a.s.sociation. We planted the seed in a narrow trench two inches deep; then filled the trench with saw dust; level with the surface. The saw dust serves as a mulch to hold moisture for the young seedlings and hand weeding between trees is reduced to a minimum.

It is also possible to use the wheel cultivator between the saw dust marked rows before the shoots appear. This was a great help in controlling early weed growth.

We were troubled with cutworms cutting off the new seedlings close to the ground, the same as they cut off young tomato plants. We controlled them by using a poison-bran bait as described in Leaflet Number Two issued by the Department of Agriculture.

All trees are grown from seed of trees growing in the Rochester area.

These had their origin from north of Pekin, China. Most of the trees are three years old when sold and have been transplanted at least once. This gives us a good sized tree that transplants well and should bear some chestnuts in three or four years. Sales are to people in our locality, although a few mail orders have been filled. So far, we have had no complaints. These are all seedling trees and until grafting or budding of named varieties becomes stabilized, I believe we should concentrate on growing large numbers of seedlings at a price within the reach of all who want chestnut trees.

This spring some large chestnut seed received from a southern grower was planted for experimental purposes. I will bring them into bearing to learn whether they will bear as large a nut in our climate as they do in the southern states, and whether the kernel will be as sweet and have as good flavor as those grown in upstate New York. I have yet to see a tree growing in the Rochester area bearing as large a nut as those grown in the southeast, and all the large nuts I have tasted did not seem to be as sweet as ours. Probably the old saying "the smaller the nut, the sweeter the nut" is true. Of course these are all seedling trees, but by this time we should know whether size of nut and sweetness of kernel are determined by climate or individual trees.

Our largest trees are eleven-year old seedlings of unknown origin. One is, I believe, outstanding. It started bearing when four years old and has consistently been a good producer. The nut is real chestnut in color and good size, running about seventy to the pound. I have not found a tree in this area bearing a larger nut. The kernel is sweet and the flavor excellent. The tree has good shape and limb structure, always sending up a central leader. This is the tree I would like to propagate.

Small Nuts Sell Better

Last fall, I tried a selling experiment with chestnuts for eating, and sold small quant.i.ties of small and medium sized nuts at the rate of $1.50 a pound. However, no one seemed interested in the larger ones.

They thought they were European chestnuts that sold here for $.25 a pound. I did not have many for sale, but I am convinced there is a market for good sweet chestnuts. It seems useless to compete with those imported from Italy. Ours are far superior, and many who remember the American chestnut, will, I believe pay a luxury price for good quality chestnuts.

In 1946, we purchased a 10-1/2 acre piece of land, 16 miles southwest of Rochester for the purpose of planting a chestnut orchard. This land had not been worked for about twelve years. The soil is heavy and fertile, typed as Poygan clay loam. Bed rock is sixty feet below the surface. The following spring, we planted about 300 trees and each year more are set out. There are now about 700 trees from two to five years old, and most of them are growing well.

The rows are twenty feet apart and the trees stand fifteen to twenty feet apart, in the row. I know this will be too close when the trees are full grown, but we have the trees and I want to bring as many into bearing as possible, searching for the ideal tree. We also expect to lose some trees through wild life and other causes.

Many of the first trees planted were lost the following year due to excessive rainfall, poor surface drainage, rabbit and meadow mouse damage. In 1948 two 400 foot drainage ditches were dug across the property. This made it possible to plant trees successfully on most of the land. However, another ditch is needed to eliminate a low spot, then all of the land can be used.

The meadow mouse that girded so many trees could not be controlled by the use of poison bait and the rabbit also did considerable damage.

Through the wild life service of the Department of the Interior, we obtained a repellant that was effective. It is distributed in the eastern states by the Rodent Control Fund of the University of Ma.s.sachusetts. We have used it now for two years and have no more mouse or rabbit damage.

The woodchuck does considerable damage even though we have eliminated all their dens on our land. They come in to feed from the neighboring areas and will have to be controlled by shooting. Deer are also present but have as yet caused no damage. Probably, they are waiting for the trees to grow larger.

Last spring, new growth on the trees was killed by a late freeze--a most unusual occurance for this area. This was caused by an excessively warm April, followed by below-freezing temperature in the middle of May. It was the first time in the memory of the oldest residents that black locust and native black walnut trees were damaged by a spring freeze.

However, most of the trees recovered, but their growth was r.e.t.a.r.ded.

This spring several of the trees blossomed, but set no burs. In a few years, I hope to have more to report on this orchard project.

(Here was shown a chestnut tree picture.)

MR. SALZER: If anyone has any comments, if they think it has good limb structure, that's what we are looking for.

MR. SHERMAN: We could tell you better if we could see it when it's dormant.

MR. WEBER: What sort of a cultivator do you use?

MR. SALZER: Wheel cultivator.

MR. WEBER: Why don't you get a Wheelmaster? You may not want to cultivate as often as if you had a power one.

MR. CHASE: We shall now have another chestnut paper by Alfred Szego of Long Island.

Chestnuts in Upper Dutchess County, New York

ALFRED SZEGO 77-15A 37th Ave., Jackson Heights, New York City

Pulvers' Corners, a collection of farmhouses, a gas station and ice cream parlor is located about 8 miles from the northern Connecticut border not too far from the southwestern tip of Ma.s.sachusetts.

The Berks.h.i.+re hills roll through here and at this point we find ourselves at approximately the northern limits of the deciduous hardwood forest belt.

Here the American chestnut is native formerly growing in great abundance until stricken a mortal blow by the invincible chestnut blight.

Just a few hundred feet north of here on a hilltop, I started in 1945, a different kind of nut tree plantation.

Placing main emphasis on the chestnut, a start was made on the cultivation of the thousands of sprouts and seedlings on my 43 acre coppice forest.

A cl.u.s.ter of ~Castanea dentata~ seedlings that appeared promising was selected. The following practices proved fairly successful in keeping a few trees healthy, and bringing one into bearing in 1950. For the interest of fellow members working along a similar line, I enumerate the following practices.

1. Clean and thorough tree surgery, cutting out blight cankers immediately upon discovery.

2. Removal of all very blight susceptible nearby sprouts and the burning of all infected branches and material.

3. Artificial watering during drought periods.

4. Application of superphosphate, muriate of potash and trace elements.

Es-Min-El was used in our case. Our soil tests high in nitrogen.

5. Removal of all overstory trees and other interfering growth.

It may be noted that the importance of hygiene and sanitation cannot be stressed too strongly.

Our own native c.h.i.n.kapin, ~Castanea pumila~ when brought up north proves itself a delightful subject. Outside of the weevil-infested area, it becomes a hardy producer of superb little chestnuts. This species offers great promise to the plant breeder because of its very early bearing (3-4 years from seed). Perhaps hybridization with ~Castanea mollissima~ varieties may bring something very fine and valuable. This species is tender during its first year but perfectly hardy afterwards. Northern growers require special techniques to grow c.h.i.n.kapins from seed.

The strains of Chinese chestnut, ~Castanea mollissima~ in most cases do not seem extremely happy here. The trees appear to sustain varying degrees of winter injury. The tips of the branches often freeze. Usually the branch comes into leaf on the lower part first and then upwards.

However, a few individuals appear perfectly hardy. The outlook is excellent for the discovery of exceptional individuals suitable for the northern zones.

The j.a.panese chestnut, ~Castanea crenata~ shows very good adaptation to this region. Although my trees of this species are young, very vigorous growth indicates some value here. Unfortunately, the nuts have a bad after-taste when eaten raw thus limiting its commercial possibilities. I have noticed this undesirable characteristic in tasting hybrid nuts derived from trees possessing ~Castanea crenata~ parentage. I was informed at Beltsville that the hybrid known as S8, a cross between ~Castanea pumila~ and ~C. crenata~, was rejected for its poor quality nuts.

I have established many other species of chestnuts and their hybrids.

Some of these are from seed obtained from the Bell experimental plot of the U.S.D.A. at Glenn Dale, Maryland. Seed from this source has produced a much better grade of seedlings than those from anywhere else.

A somewhat different version of the tin can planting method is now being used here. Number two size and larger tin cans have a few punctures made with a hammer and nail in the bottom. These have their tops removed, of course, and after being filled with loose soil, are used as pots in which to start chestnuts.

In the early spring germinating chestnuts are removed from jars, kept in my refrigerator. One is planted in each can flat side down, barely beneath the soil level.

After the season has warmed up these "canned plants" are set out in a trench, buried to the rim. Rock wool is placed around the stems of the seedlings covering the soil and the nut. This has acted as a rodent deterrent.

The "canned plants" are then, at leisure, set out in their permanent places. Just before doing this an ordinary beer can opener is used to enlarge the punctures in the bottom of the can to permit the roots to penetrate better. In a few years the can should disintegrate entirely and at no time will interfere with root growth.
