LOGANBERRY CULTURE IN 
the vines grow fast in the fall of the 
year, and the sooner it is done the few- 
er vines there are to handle. If the 
vines are to be tipped they should be 
trained down within about 12 or 14 inches 
of the ground so they will grow about 
the right length before tipping, but if 
no more plants are wanted they should 
be run out on the wires. As soon as 
they are trained the old vines should 
be cut up ready for the land to be plowed 
after the first rains in September. 
The cost of cutting out the old vines 
and training up the new ones is about 
$12 per acre each year if done the first 
thing after picking. If they are left for 
some time afterward the expense will be 
considerably more owing to the extra 
growth the new vines have taken on. 
One of the most important things in 
connection with loganberry culture is 
the cutting out of the old vines. This 
should be done as soon as possible after 
the picking season is over, as they are 
taking the strength out of the roots that 
should go into the new vines for the

next year’s crop, and if there is any dis- 
ease in them it is spreading to the new 
vines. If they are taken out early and 
disked up in the rows I think there is 
very little danger of any disease spread- 
ing from them, and they make a good 
fertilizer. Some growers have resorted 
to spraying their vines for anthracnose, 
but a close inquiry reveals the fact that 
the new canes were left lying on the 
ground during the winter, where they 
are far more susceptible to disease than 
when trained up on the trellis. The cost 
of spraying is said to be about $1 per 
acre when put on in good shape with a 
power sprayer. As stated before, how- 
ever, if the vines are cut out as soon as 
possible after picking, and the new ones 
trained upon the trellis so as to disc up 
the old ones and plow them under, I 
think there will be no need for spraying 
for several years to come. Some growers 
are also taking the old vines out and 
burning them, but I think this is a 
mistake and an unnecessary expense.
