Part 4
Our function is in educating more people to an appreciation of what improved nut trees are and what they can do as they are at present developed. Nut growing is just beginning to come into its own and the nut tree should take its place as a valuable shade tree, should be included in the home orchard and used as a paying crop by the farmer in the North. The Guild is especially interested in introducing and popularizing new horticultural developments. It publishes a new type of tree as a publisher does a book. We serve as a connecting link between the horticulturist and the layman, aiming to coordinate the work of horticulturists and to interpret the meaning of this work to prospective planters of trees. We act as a sort of educational sieve, our aim being to extend the number of tree planters. This is a sales job and the Living Tree Guild is a sales organization. We work through the press by means of conservative advertising and publicity articles, through personal contact by means of exhibits and individual interviews and through the mails by means of carefully prepared bulletins of information and well selected photographs. We work to gather all the authentic information and offer this to our customers as a unique service. Frankly we believe that there is no other organization in the country that is as closely associated as we are with the authorities on tree planting. Dr. Morris, whom we all know as the dean of northern nut culture, is a member of our Board of Advisors.
In order to symbolize the grafted nut tree the Guild has adopted a brand name, Guild Pedigree, based on the fact that the mother trees have been carefully selected and are well known for their quality. Experiments have shown that they represent a selected family line and develop true to its characteristics.
We have been in touch with northern nut tree planting for a good many years, but our sales work has been limited to the past three years which, of course, means that we have never tried to sell nut trees in so-called normal times. Yet Guild Pedigrees have bucked these economic obstacles and they are becoming recognized as offering a remarkable opportunity to the business man who has property and to the busy farmer to make their idle land productive with a minimum amount of care and attention. They realize that the difficult operation of grafting has been successfully accomplished and that they need only prepare the ground for planting according to the character of the soil and with a little pruning and cultivation within a few years may be assured of a new type of crop for which there is a growing demand. They recognize the value of these trees over ordinary fruit trees which require numerous sprayings a year and whose extremely perishable crop must be carefully picked from the trees. Everyone knows that a certain amount of effort is required to get good returns from farming, but comparatively speaking improved nut trees have a decided advantage in their facility of growth, which means that they can be planted by a much wider range of growers than almost any other kind of crop.
In all of this we speak primarily of the black walnut which we recognize as the best nut tree for extensive planting in the North. We believe the hazel hybrids and filberts are of value as a secondary nut crop, as fillers-in between the black walnuts or used as ornamental bushes for screening around the grounds. Where local conditions justify it we recommend that the home orchard include a variety of nut trees, the English walnut, the northern pecan, certain hybrid hickories and a highly blight-resistant chestnut. The Guild has realized from the start that most laymen know little or nothing about the planting of nut trees. We, therefore, work with them individually, advising them in detail on their particular plantings. We keep a record of all Guild Pedigree nut trees, particularly of the black walnut, each one of which bears a tag with a serial number. We keep a record of this number and are gradually building up a case history of each tree, in so far as possible, in some instances complete with photographs. We include the conditions under which the tree was planted, whether as an orchard or as an ornamental tree, the amount of care and attention given it and its gradual development and increase in bearing. This is also being done with every tree that is included in the experimental orchard the Guild is operating in the Connecticut River valley.
The data that we are obtaining in this way is aiding us in publishing the latest authentic information on what happens when nut trees are planted by laymen under varying conditions. We believe these records will be a unique contribution of the Guild to northern nut culture. By this means we can already point to certain Guild Pedigrees as having made unusual growth or only average development, together with the probable explanation, and of course to some that have died from natural causes or from attacks by woodchucks or the like. We can offer records of plantings of Pedigrees that have been made in practically all the leading states, Canada and even abroad. Perhaps one of the most interesting case histories is that of Pedigree No. 1527 which was planted in the spring of 1932 as a Washington Bicentennial tree. This tree, set as a single specimen, came into full leaf immediately after planting and a year later was all of seven feet tall and had three mature black walnuts for its first crop. It is the proud possession of two small boys.
Young as we are in the field we have given authentic information on the planting of northern nut trees to several thousands of tree lovers. We have found a definite demand for detailed knowledge, and recognition of our work has been shown by the great interests in exhibits we have staged and from several awards which we have received from such organizations as the Horticultural Society of New York. An analysis shows that Guild nut tree plantings range from the true farmer to the gentleman farmer, from the small lot owner to the owner of hundreds of acres of non-dividend paying land, from the keen horticulturist to the youth who is taking his first step in following a fascinating new hobby.
The selling of nut trees is a very special problem. It is not like selling other kinds of trees. We recognize the fact that those who plant Pedigree nut trees are in a class by themselves and we, therefore, set up a separate department for them, making a special study of the subject. We feel certain that there is a great future ahead for nut growing in the North with our associations cooperating in the distribution of information and stock developed from actual experimentation over a period of years. Above all it is important to understand what others are doing, and appreciate that the commercial side should go hand in hand with the purely horticultural.
Progress Report on Nut Growing in the Ithaca, N. Y. Region
_By_ DR. L. H. MACDANIELS
_New York_
The status of nut growing in the Ithaca region was reported at the Washington, D. C. meeting of this association in 1932. Since that time there has been little change in the situation except that a few more of the varieties have come into bearing, and the severe winter of 1933-34 has injured the trees of many varieties.
The plantings in the vicinity of Ithaca are confined chiefly to those of the Department of Pomology at Cornell University, and those of Mr. S. H. Graham who is a member of this association and has been planting nut trees for many years. Other than these there are only scattered trees either native or planted around the dooryards by amateurs without any very keen interest in northern nut growing. The purpose of the plantings at Cornell University is primarily to test out varieties for their suitability for growing in the rather rigorous climate of the region. Farmers and others throughout New York state look to the experiment stations for information regarding the possibilities of nut culture and the varieties which might be planted to advantage.
As has been pointed out previously, the number of varieties adapted to the region is distinctly limited because of unfavorable climatic conditions. These climatic conditions are more fully described in Bulletin 573 of the New York State Agricultural Experiment Station at Cornell entitled "Nut Growing in New York State." The breeding of new varieties and other investigational work is being carried on at the Geneva Experiment Station where, as you know, Prof. G. L. Slate has been growing many varieties of filberts for some years.
The university plantings at Ithaca consist of about an acre set about 20 years ago, including a number of varieties of different nuts recommended for planting at that time. There is also about an acre of "butterjaps" which are growing vigorously but have shown little promise of value because of a lack of hardiness and generally poor cracking quality. The most important planting is about 5 acres of cleared woodland in which many hickories have come up naturally. These have been top worked to many of the leading hickory varieties. A considerable number of walnut stocks have also been planted in this area and top-worked to walnut varieties. Plans are under way to acquire 10 or 15 additional acres to be used for further variety tests as new varieties are brought to light in the various nut variety contests which are being carried on.
Up to and including 1934 the black walnuts that have fruited are the Thomas, the Ohio, and the Stabler. Of these the Thomas is the only one which is at all satisfactory. This variety has fruited 3 years in succession and has matured well-filled nuts every year. The Ohio and Stabler have been shy bearers and in addition the nuts have been small and not well filled. Both are evidently adapted to a longer growing season than that at Ithaca. In 1934 one Stambaugh graft matured about 40 nuts. This variety appears promising but needs further testing. In another year or two at least a dozen more of the promising varieties of black walnuts should come into bearing.
Among the hickories the Barnes, of which there are 3 trees, has fruited several times but in no case have the nuts been filled. The Brooks, the Stanley, and the Weiker have also fruited sparingly but the nuts have not been filled. During the past season, 1934, a few nuts were borne on the Taylor, Kentucky, and Vest hickory trees, which were well filled. It may be that these varieties will prove suitable for the region. The Kentucky looks particularly promising. The Beaver and the Fairbanks have borne a few nuts but the quality is not sufficiently good to make them worth growing. The Burlington hybrid pecan makes a very beautiful tree and has set nuts in several seasons, but they are not well filled. About half a dozen varieties of northern pecans have been fairly hardy but the seasons are too short to mature the nuts. They have always been frozen on the trees while still very green.
During the past winter the temperature went down to -35 deg. F. at the University orchard. This killed most of the Persian walnuts outright. Even the hardy varieties, Rush and Hall, were killed back to a few buds on the trunks and larger branches. This experience has been quite general throughout New York where the temperature went down below -25 deg. F. It is to be hoped that some of the new sorts being introduced from the Ukraine will be better able to stand the low temperatures experienced in New York. The low temperature very seriously damaged the 60 Chinese chestnuts growing in the University orchard, killing the terminals back for several feet and the sapwood all the way out to the combium and down to the snow line. The trees so injured made only fair recovery and it is doubtful if they are worth saving. Some Chinese chestnut trees nearer Cayuga Lake where the temperature only reached -27 deg. F. were only slightly injured. It would seem, therefore, that around -30 deg. F. was the critical temperature for the Chinese chestnut. The Japanese walnuts were not injured seriously by the cold weather of the winter. Many of the more tender seedlings had already been eliminated by the cold winters of the past. The Japanese walnuts were, however, badly damaged by the late spring frost which froze off the catkins and new shoots. This has occurred several times in the last ten years and is a serious drawback to the bearing of this species. Hickories and black walnuts for the most part showed no injury except in the case of rapidly growing grafts. All of the McCallister hican grafts were killed outright as were a number of grafts of the shellbark hickory (Carya laciniosa). At Enfield Park where the probable temperature was about -27 deg. F. one McCallister pecan graft survived. The filberts were quite generally damaged both in wood and catkins, except the Rush, which fruited heavily. Northern pecans had their terminals killed back about 6 inches but were otherwise uninjured.
In my judgment the greatest need of northern nut growing is the discovery and testing of new varieties adapted to the different northern regions. To find and test these varieties is probably the greatest service that the Northern Nut Growers' Association can perform. We cannot expect that nurserymen will propagate commercially the new nuts which are discovered until they are sufficiently tested to establish the value of the variety for different regions. As has been pointed out, the Northern Nut Growers' Association is in much the same position as was the American Pomological Society 100 or more years ago when information regarding new varieties was the main interest of the fruit industry. In this connection it would seem to me well worth while to carry out the idea proposed by Dr. Deming last year which he called the Roll Call of Nut Varieties. The older sorts have now been planted sufficiently widely by members of the association to make it possible to get some adequate idea of their suitability for growing in various localities. Those who have the interest of the association at heart should do all they can to obtain and grow any new varieties that offer any promise of being adapted to their locality. It is only by carrying out such a program that we shall have any real basis for making recommendations as to varieties adapted to different regions.
I must confess that I am still skeptical about a commercial nut industry in New York on the basis of our present varieties. After more than 20 years of variety testing in Ithaca only the Thomas black walnut has shown any real merit. All the other sorts that were propagated and recommended have shown themselves to be quite unsuitable to the climate. A grower setting out a commercial orchard 20 years ago on the basis of our knowledge of varieties at that time would now have practically nothing to show, except as he happened to have the Thomas black walnut, or possibly some of the hickories of northern origin. At the present time the number of promising varieties known has been greatly increased. They are, however, not available in the trade, nor will they be until they have been adequately tested to establish their merit. Fortunately some of the nurserymen growing nut trees are willing to run test orchards as well. They are few in number and of course their work must be augmented by the work of others in the association. What we need more than anything else are test orchards in different localities in which the relative yield of the different varieties over a period of years will be kept. On the basis of such data recommendations as to varieties to plant can be made with some degree of assurance that the information given is sound.
MR. C. A. REED:
Prof. MacDaniels may have told you of a number of promising varieties which he personally has been responsible for bringing to light during the last year. If he didn't I hope that he will tell as a matter of record how he came to get them and just what they are.
PROF. MACDANIELS:
Prof. O. F. Curtis of Cornell University and I made a pilgrimage of about a thousand miles back to the stamping ground of our youth with the avowed purpose of hunting down some of the best black walnuts of the region. The trip, though a hurried one, was packed with interest. In all, four walnuts were located which seemed well worth testing. Probably the best of these is the Albert Todd. The nut is thin hulled, a little smaller than the Thomas but with a thicker kernel. The tree was about dead when found but scions were procured and are now growing at Ithaca and Geneva. Another variety is the Emerson, located at Madison, Ohio. This is a large round nut with a rather tough shell and high proportion of kernel. Mr. Emerson has a good stand of native walnut growing on bottom land. A few years ago he sold 25 trees to a furniture company for $1000.
The third nut Dr. Curtis found on a previous journey to Ohio. It is a large nut of rather unusual shape being higher than it is long. It has good cracking quality and deserves further testing. The fourth walnut, the Chase, is growing in a dooryard at Oberlin, Ohio. It is larger than any of the others, with good shell conformation. It has the reputation of not always filling out the kernels, a condition which may be seasonal or possibly an inherent defect. Grafts of all four of these walnuts are growing at Ithaca and at Geneva and will be available after a year or two.
We had one disappointment in that a tree that we particularly wanted was found to have died only two years before. It was the old story of being too late. Certainly such experiences ought to spur this association to new efforts in trying to locate the best nut trees before they are destroyed.
Some Random Notes on Nut Culture
_By_ D. C. SNYDER, _Iowa_
Any notes concerning the behavior of nut trees in Iowa this year necessarily recall the trying weather conditions and these must be referred to again and again. Although winter temperatures were quite mild, catkins on the filberts and hazels were so badly injured that none bloomed on the filberts and very few on the Jones hybrids which had previously been hardy. The native hazels bloomed but set very few nuts, apparently because of their repeatedly freezing during the blooming period. The Winkler hazel seems to be a phenomenal individual and a poor parent, not reproducing anywhere nearly true. Thus far all its seedlings have produced nuts inferior to the parent variety even when they were from seed which was cross-pollinated by other choice hazels or filberts. They do, however, show much variation in foliage, bushes and fruit and what the second generation may bring forth is yet to be determined. Established hazel plants endured the extreme heat and drought splendidly, but newly planted bushes did not. Well-rooted layers and divisions planted out early made a splendid start, then backed up and were a total failure before the July rains came.
That you may know how dry it was in Iowa the first six months of 1934, let me tell you that only about two-thirds of the oats sown in April in well prepared soil got moisture enough to germinate then, and about the same part of the corn planted in May germinated. Well, along in June a shower furnished enough moisture to germinate the remaining part, so we had corn 2 to 3 feet high and in adjacent hills only 2 or 3 inches high, and oats which were headed out mixed with others of the same sowing which were just up.
The walnuts endured these extremely dry conditions better than any fruit or nut bearing trees. Young seedlings made quite a satisfactory growth and year old seedlings lined out for future grafting made almost a perfect stand, as did the grafted trees which were unsold and lined out at the end of the selling season. The heavy loss in walnuts was in the grafts set in May. This will be mentioned later.
The shortage of moisture in 1933 apparently was responsible for considerable winter killing of young hickories which were in sod. There was no loss in cultivated ground. The hickories were like the apples this year in that they did not bloom much, and unlike them in that the apples ripened ahead of their normal season, while the hickories ripened later. Stratford nuts are usually ready to gather September 1 but this year are still clinging to the trees. Fairbanks is our most prolific kind. Nuts closely resembling Fairbanks, yet somewhat different from it, keep bobbing up on different sides of us when there is a good crop of hickory nuts. None of them have yet been superior to Fairbanks. Perhaps one should give each a good testing and keep up a search for one with better quality than Fairbanks. Certainly there is no reason for calling Stratford a hybrid. It is one of a group of shagbarks with smaller leaves and buds, and thinner husks than are found in what we would call a typical shagbark. The shagbarks might be divided into several species and be as distinct as some of the species of other trees, such as the ash for example. Vest and Hand represent another group with thin, wavy shells and thereby are quite distinct from the typical shagbarks.
