door frames or in the greenhouse. Many conifers do not come true 



from seed. Three types 

 of cuttings are used: 

 simple, heel and mallet. 

 The simple cutting 

 (see fig. 21) is the sort 

 mentioned previously in 

 the case of soft wood and 

 hard wood cuttings. The 

 heel cutting (see fig. 22) 

 differs in one respect only, 

 in that it has a small slice 

 of the parent stem at- 

 tached at its base. The 

 mallet cutting (see fig. 

 23), as the name infers, 

 has at its base a small or 

 large piece of the entire 

 stem to which it was at- 

 tached. The two latter 

 sorts of cuttings are 

 thought to be better be- 

 cause of the food stored in 

 the parent stem. Heel 

 cuttings are especially 

 useful in the case of those 

 evergreens which root very 

 slowly.
