 Sprouting of 

 Seed: There are 

 several methods 

 used in preparing 

 the seed for sprout- 

 ing. Some growers 

 have practiced 

 planting in the fall 

 in the open ground 



in the nursery. 

 Franquette Walnuts . , 



There are several 



difficulties in this method. One is that the nuts do 

 not often germinate over-well. In fact, some of the types of 

 black walnuts may remain in the ground two years before they 

 germinate, and there is some danger of decay. However, where 

 it is desired to grow seedling English walnut trees, it is the 

 common practice of our nurseries to plant the nuts in open 

 ground in the nursery row in the fall. 



Another danger to be watched out for is that of squirrels. 

 If given the opportunity, they may purloin the entire patch. 



Other growers have practiced stratifying the seed in boxes 

 in sand. When this is done the nuts are often stratified in the 

 fall. Care must be taken, however, that the sand does not 

 become too wet, for if it does, the nuts will mold, and there is 

 danger of decay. On the other hand, if the sand is allowed to 

 become too dry, the nuts will not germinate. One of the most 

 satisfactory methods is to wait until late winter, or early spring, 

 say in February. Choose the 

 warm, sunny side of some build- 

 ing. Lay down a few 2x4's and 

 upon these put boards. Spread 

 on the boards a few inches of 

 moist sand then spread the nuts 

 on this moist sand and cover 



them with additional sand. If
