RASPBERRY

The black and the red types are distinct in flavor, and both should be
grown. The blackcaps need more room, about three by six or seven feet;
for the reds three by five feet will be sufficient. The blackcaps, and
a few of the reds, like Cuthbert, throw out fruiting side branches, and
should have the main canes cut back at about two and a half feet to
encourage the growth of these laterals, which, in the following spring,
should be cut back to about one-third their length. The soil for
raspberries should be clayey if possible, and moist, but not wet.
