PEOPAGATION OP TREES AND PLANTS 303 



The blackcap raspberry is propagated by the ends 

 or tips of the canes taking root. This takes place to 

 a limited extent without assistance, but to obtain the 

 largest number of plants the ends of the canes should 

 be carefully covered with one or two inches of soil the 

 last of August or early in September. The layer or 

 "tip" plants (Figure 76) are better if not taken up 

 until the following spring, but if carefully dug and 

 handled, it may be done in the fall with a fair degree 

 of success. The tips should not be planted in the field 

 until spring. 



PROPAGATION OP THE STRAWBERRY 



The strawberry is not generally grown as a nursery 

 product alone, but the plants for setting new fields are 

 often taken from the fruiting plantations. To a lim- 

 ited extent this practice is not seriously objectionable, 

 but, as many kinds are often grown in the fruiting 

 fields more or less closely together, there are many 

 chances of their getting mixed. The plants cannot be 

 as well dug as from a bed where all are to be removed, 

 and therefore it is better to have all plants grown in 

 beds where no fruit is expected. A" method practiced 

 by some of the experiment stations and others, called 

 "summer bedding," is found very satisfactory. This 

 consists in heeling-in, or planting in close rows or beds, 

 the runners that are thinned from the rows or the field 

 during the summer, where they remain until the follow- 

 ing spring, when they may be set in the field at any time 

 from the first of April to June without being checked 

 in transplanting. In this way runners that have made 

 but very short roots, if heeled-in and shaded for a day 

 or two, will make strong rooted plants in a few weeks, 

 and each plant will have full exposure to the air and 

 sunlight, thus making very strong plants.
