Propagation of the Blackberry 93 



in trenches two to three inches deep, depending upon the 

 comparative heaviness or lightness of the soil, and about 

 three inches apart in the furrow. They are covered and the 

 soil firmed over them, the same as in planting peas, pota- 

 toes, or any other garden vegetable. Mulching the ground 

 with a light layer of straw, sawdust, or similar material, 

 to prevent it from drying out, aids their growth and helps 

 to insure a good stand. 



For those who have greenhouse facilities, a very satis- 

 factory way is to take up the roots and make the cuttings 

 as early in spring as the ground will permit, stratifying 

 them in boxes of sand as already described, and placing 

 them under the greenhouse benches. Later, as other 

 plants go outside and space permits, these boxes are 

 placed on the benches. By this treatment the cuttings 

 become callused, and are in good condition to go into 

 trenches outside by the last of May. 



With an especially choice variety where it is desirable 

 to increase the stock with the greatest possible speed, 

 the cuttings may be made smaller, one-half to one inch 

 long, and the whole operation be carried on under glass. 

 Such cuttings are best placed just beneath the surface in 

 beds of sand, and furnished with a gentle bottom heat. 

 The plants are potted off as soon as buds have been de- 

 veloped and are well under way, or when leaf -growth has 

 begun. Sometimes they are sown in shallow boxes of 

 soil after the callus and buds have developed, and allowed 

 to remain till several inches high, then potted, or even 

 set from here directly into the open field, if the weather 

 and soil are in suitable condition.
