THE BLACKBERRY





The large-growing sorts are set as much as six by eight feet apart,
though with careful staking and pruning they may be comfortably handled
in less space. The smaller sorts need about four by six. When growth
starts, thin out to four or five canes and pinch these off at about
three feet; or, if they are to be put on wires or trellis, they may be
cut when tied up the following spring. Cultivate, mulch and prune as
suggested above.
Blackberries will do well on a soil a little dry for raspberries and
they do not need it quite so rich, as in this case the canes do not
ripen up sufficiently by fall, which is essential for good crops. If
growing rank they should be pinched back in late August. When tying up
in the spring, the canes should be cut back to four or five feet and
the laterals to not more than eighteen inches.
Blackberry enemies do not do extensive injury, as a rule, in well-
cared-for beds. The most serious are: (1) the rust or blight, for which
there is no cure but carefully pulling and burning the plants as fast
as infested; (2) the blackberry-bush borer, for which burn infested
canes; and (3) the recently introduced bramble flea-louse, which
resembles the green plant-louse or aphis except that it is a brisk
jumper, like the flea-beetle. The leaves twist and curl up in summer
and do not drop off in the fall. On cold early mornings, or wet
weather, while the insects are sluggish, cut all infested shoots,
collecting them in a tight box, and burn.
