Dr. Smith: Have you any objection to partial topworkingi of 

 walnuts? One limb? 



Dr. Morris: I am afraid your established top would take ad- 

 vantage and not allow grafts on one limb to grow. That is not true 

 of apples however. I have grafted a single apple limb in a full foliage 

 tree and grafts all grew. With the nut trees or hardwood trees I 

 think it would be rather risky. I tried that and did not get good results. 



Dr. Smith: How many grafts would you have to a large tree? 



Dr. Morris: In a tree 30 feet high you would have to use more 

 than 100 grafts but you will get your new top started right off. It 

 pays because you will have a full crowned tree more quickly.
