an equal opportunity for growth. Should both the cions in 
a branch grow, the weaker one

The spring following the top-grafting, all or a part of the 
branches left on the stock at grafting should be pruned off 
to encourage growth of the grafts. If the tree 
is large, and of a vigorous variety, it is wise 
to leave a part of these branches until the 
second spring.

formerly much used for tying grafts and buds, but has been largely supplanted by

dealers in nursery supplies.
