Left: 2nd year. Let shoots develop from top 4 buds, rub off all others. 
Right: 3rd year. Prune back to 4 spurs. 
When growth begins and frost danger is past, rub off al] shoots 
along this young trunk except the top four. ‘These should be 
allowed to grow, and each of them will try to produce a bunch or 
two. Pinch these off, if grapes are actually set, or at any rate 
don’t leave more than two or three bunches if vine is ultra- 
vigorous, for vines should not be overtaxed this second season. 
Spray three times with Bordeaux mixture plus DDT: (1) just 
before grape blossoms begin to bloom; (2) just after the young 
berries are set; (3) two weeks after post-blossom spray. (Cau- 
tion: In Japanese beetle areas it may be necessary to give addi- 
tional sprays, as above, to control them.) 
THIRD SEASON. Vines ready to bear first crop. The four shoots 
allowed to develop previous season will have become woody 
canes. For spur pruned, prune these four canes back to stubs, or 
spurs, of two buds each and trim off any side growth that may 
have developed. For long-pruned and half-long pruned varieties, 
4th year. Cane pruning.
