Planted with Registered Stock Spring of 1939. Picture taken Sept. 1 same year 
should be taken to prevent break- 
age of the tender sprouts. The 
“handle” or woody cane of tip 
blackcap plants should be removed 
at planting to prevent anthracnose 
infection. 
Isolation 
Start your new planting on clean 
soil well isolated from outside dis- 
ease sources. Do not plant black- 
caps near any of the red varieties 
except Newburgh. This variety 
seldom is affected with the virus 
diseases. 
Soil 
Raspberry ground should be 
deep, well aerated, fertile with 
plenty of humus, and well-drained. 
Raspberry roots will not stand ex- 
cess water. 
Fertilization 
Liberal applications of a nitro- 
gen fertilizer or manure should be 
made early each spring. About 300 
pounds per acre of an ordinary nit- 
rogen fertilizer is the correct 
amount for a planting after its 
first year. 
Summer Pruning 
In order to promote strong, 
stocky plants, the terminals of new 
blackcap canes should be pinched 
out when they reach a height of 18 
inches. This procedure stimulates 
lateral growth which will produce 
most of the fruit the following 
year. Reds should not be pruned 
in summer. 
Winter Pruning 
Blackcaps should be pruned in 
late winter. The laterals should be 
cut back very severely to a length 
of 8 to 12 inches from the main 
cane. Red raspberries should be 
pruned lightly; in general the top 
one-fourth of the canes are re- 
moved. 
Spraying 
Raspberries should be sprayed 
for Anthracnose each spring when 
the buds first show green with 
liquid lime-sulfur, one gallon to 19 
gallons of water. One application 
only is recommended.
