There are a few cultural problems. The ones that we have encountered at Geneva have been winter injury, particularly of the catkins, and also some of them have not been as hardy in wood as we would like. We have had no trouble with filbert blight, presumably because we are isolated from the wild hazel, which harbors this blight. Dr. MacDaniels has had trouble with his planting at Ithaca with filbert mite.
With this introduction, which is mostly varieties and breeding, because that seems to be my interest, I'd like to call on some members of the panel to get their experiences. Mr. Snyder raises nut trees in Iowa where winter injury is probably much more serious than we have at Geneva. At Geneva we have a fairly respectable climate and can get a crop of peaches about nine years out of ten. In Iowa they have a lot more sunshine, and I think probably sharper drops of temperature than we have at Geneva. I'd like to have Mr. Snyder tell us what his experiences have been with filbert varieties.
MR. SNYDER: I really didn't know that I was to be on this panel until I got here. I thought I was on the hickory panel. As Mr. Slate says, our climate is more severe that that at Geneva. We can get the very hardiest peaches to bear about two years out of three, and the trees are severely injured in between. So that will give you a little idea as to the climate in that respect.
We made quite a planting at one time, maybe 30 of the Jones hybrids, and they did quite well for several years, and then between the winter-killing and the blight most of them are dead now. The Winkler, of course, is an Iowa nut and was introduced by our people and did very well for a number of years but has backed out on us the last several years, too, I believe due to this same mite trouble that Dr. MacDaniels reports in New York. They just don't bear. The bushes are quite healthy, and we get plenty of catkins, but we don't get any nuts to amount to anything.
We have a little bush of the Mandchurian hazel. It isn't worth mentioning as a nut producer, but it does have very attractive foliage and seems to be entirely healthy, produces perhaps three to five nuts a year on a bush as high as your head. You may be familiar with it. The foliage is very distinct from anything I know. The leaves are truncate at the end, cut off quite square, with just a little point in the middle.
MR. SLATE: I don't have that.
MR. SNYDER: That is standing our conditions all right, and several years ago Mr. Reed sent us what he said at the time were Chinese tree hazels, but later he retracted and said that they were not Chinese tree hazels but they were hybrids of the Chinese tree hazel. There were four of those plants; one of them was a tremendous grower. It would grow six feet or more a year and commence bearing in a year or two. But the blight hit it and cleaned it out. There is only one left now, one of the slower-growing ones, and while it promises to become a tree, it is a very irregular-growing one. I think it had half a dozen nuts on this year.
The Turkish tree hazel, of which I have two trees, were very badly damaged by a very severe hailstorm 12 or 15 years ago, which completely peeled off the bark on one side. That was in early July, and we were afraid to cut them off and let them grow up new for fear it would kill them. They have finally developed into quite beautiful upright trees. Also they have more than one stem from the bottom. One of them produces a great abundance of catkins, but neither of them has produced any nuts yet, and they are 14 feet high or more, good-sized trees and very attractive. The foliage is very beautiful, and it remains healthy. I don't know that there are any other varieties that I can name.
MR. SLATE: We have had several of the Turkish tree hazels, Corylus colurna, growing at Geneva for two or three years. They came from the Rochester State Park. We have one tree which Mr. Bixby imported from China, as Corylus chinensis, but recently I had it checked by Dr. Lawrence of the Bailey Hortorium and he assured me that it was Corylus colurna. I think these make a very handsome tree. I like that rough, corky bark they have as they get older. The trees in Highland Park at Rochester are the largest, perhaps, in the country, certainly the largest that I know anything about. They are at least as large as a very large apple tree. They have been fruiting for some years. The trees at Geneva have not fruited very much. I don't think you can expect much in the way of nuts until the tree is about 15 years old. This year one of our trees has a number of nuts on it. The nuts are too small and too thick-shelled to be of any great value for nuts.
Now, Mr. Whitford, you have had some experience with the filbert varieties. Which one would you recommend?
