SETTING PLANTS. 
It is a good plan to grow the variety which has done the best in 
that locality. It is better to secure home grown plants when such are 
available rather than to use plants brought from a distance. 
Age of Plants .—It is believed that yearling plants are the 
most desirable for the new plantation. By this we mean those plants 
which have grown one full season and not those that were started the 
summer before. In some cases it is perhaps possible to get good stocky 
plants which were started the summer before but generally these are 
small and spindling and have a poor root system. 
Time of Setting .—In Colorado the best time to set raspberry 
plants is in the spring. This should be done just as early as is pos¬ 
sible to avoid any damage from severe frosts. As a rule, the 
middle of April is a good time. For this reason it is well to have the 
land plowed the fall before. 
Distances .—The distances that raspberry growers use in setting 
out new plantations vary somewhat according to variety and locality. 
In those localities where the winters are not severe enough to require 
laying down it is not necessary to plant the rows as far apart as where 
protection from the winter is required. Where protection is necessary 
the distance for the red raspberry between the rows is seven feet apart 
and in the row two feet and eight inches. The distance in the row can 
be greater than this providing the pin system of laying down is not used. 
This distance varies from that mentioned up to three and a half feet. 
In those localities where laying down is not required for winter pro¬ 
tection, the distance of five to six feet for the rows and from three to 
five feet in the rows is used. This enables cultivation to take place 
both ways. It requires 2333 plants per acre when set two feet eight 
inches in the row and rows seven feet apart. 
The black-cap varieties in those localities where winter protec¬ 
tion is not used, should be planted with rows the same distance 
apart as for the red, that is, about seven feet and about five feet in 
the row. Where covering of the black-cap is necessary it is better 
to have them a little closer than this, from three and a half to 
four feet. This latter distance will require severe pruning of the 
plants to keep them from forming a hedge row. The purple cane 
varieties can be the same distances as the black-cap which in habit 
they so closely resemble. 
Method of Setting. —A good method of planting is to have the 
rows staked off the desired distance from each other and plow a deep 
furrow where the rows are to be set. Set the plants by hand the de-
