PLANT PROPAGATION

strawberry runner, showing young plants rooted 



in the cut. This wedge must have the cut surfaces perfectly straight, 

 not hollowed out, if the union is ta be a good one. In inserting the 

 cion two cambium rings must be together; this is the part between 

 the bark and the wood. To be sure of this, slant the cion just a trifle. 



Then cover over the 

 whole cut area with 

 grafting wax. 



The next most 

 common method of 

 grafting is known as 

 whip-grafting. It is 

 especially used upon 

 small branches or for 

 gretfting seedlings. 

 Apple seedlings may be nicely grafted by this method. Branches 

 to be grafted must be nearly the same size. The stock should 

 be beveled 'off with a long plane surface; the cion should be beveled the 

 same way. Then each should be split so that the two tongues fit 

 together nicely. Practise a bit uppn some other wood and you will 

 leam more by the experience than words can tell in description. As 

 in all grafting, the layer between the bark and wood of each must be 

 in contact on one side at least. This sort of grafting, like the former, 

 should be done in Spring before growth starts. This graft" may not 

 be covered with wax, but merely tied firmly. A cord used for this 

 purpose is usually No. 18 knitting cotton soeiked in grafting wax. 

 This is just strong enough to break when it should, before the branch 

 is strangled. 



Method of tip-layering of Raspberry and Blackberry 



Layers. By layers we mean that some portion of a branch has 

 been placed in contact with the soil so that it may root. Many plants 

 root very readily by this method, and as it is very convenient, per- 

 fectly simple and certain, it can be used in every garden for some
