Northern Nut Growers Association Report of the Proceedings at the Thirty-Eighth Annual Meeting — Part 37

Other types of nuts growing at the Horticultural Experiment Station are of general interest. The chestnuts and most of the pecans are very young and so are not bearing. Several hickories, =Carya ovata= and =C. laciniosa=, and Japanese walnuts bear some nuts occasionally. The Persian walnut x black walnut hybrids bear a few nuts sometimes but are worthless; the trees however, are nice as ornamentals. The Japanese walnut x butternut hybrids usually have a nice crop but the nuts are of questionable value. The trees are nice ornamentals although subject to wind injury.

Several seedling Chinese chestnuts were topworked to selected Chinese chestnuts, grafts of which were obtained from the Division of Forest Pathology of the U. S. Department of Agriculture. Unfortunately these were all destroyed at the result of construction work.

In addition to plantings made at this Station, nuts and nut seedlings have been distributed to people who wished to grow a few nut trees on their own places.

Cultural practices have been very simple at the Station. After planting, the trees were cultivated for a year or two, then the space between sown to grass and clover and the space just around the trees was mulched with manure, hay, etc. The grass is cut several times a year and placed around the trees as additional mulch. Small quantities of a good commercial fertilizer such as 4-8-10 have been applied occasionally and some nitrogen also has been used.

Pruning has been reduced to a minimum, a light thinning out of branches being given as required. Very little attempt has been made to keep filberts to a single stem, but the walnuts have been kept to a single low-headed trunk.

There has been a marked increase in interest in the planting of nut trees in Ontario since the first plantings were made at the Station. These Station plantings serve to demonstrate in a small way that nut trees can be grown in the Niagara fruit belt of Ontario. The feasibilty, however, of growing nut crops in a commercial way, even in this district, is still open to question, although it is felt that farmers and others should be encouraged to plant a few nut trees on their property both for the sake of the nuts and because of the ornamental nature of the trees.
