Pruning the cropping tree Pus
Each May, once the cordon has passed the top wire and reached the required height usually 7 ft , cut back the extension growth to its origin. Each July subsequently, cut the leader to 1 in. From mid-July onwards the remaining shoots on the cordon are pruned on the Modified Lorette System see above . If, later on, there are secondary growths from shoots pruned in July, cut them back to mature wood just before leaf-fall. In areas 3 In late July, cut back laterals longer than 9 in arising directly...
Vinifera grapes
The Four-Arm Kniffin system is the method generally chosen in warm climates, but a modification called the Spur system is used for varieties such as 'Csaba' and 'Cardinal'. The Spur system allows the fruit-bearing arms to be permanent, that is they are not renewed annually. Each arm has 6-8 vertical fruiting spurs and each spur has 2-3 buds that produce fruit shoots. In cold climates, where tender varieties need winter protection, the Modified Chautauqua system can be used. Guyot system This is...
Quinces
1 Between November and March, prepare the ground, clearing away perennial weeds over an area roughly 3 ft square. Choose the planting position carefully. The true quince Cydonia oblonga is a native of central to south-western Asia. It has been cultivated since ancient times. It is related to the pear, for which it is often used as a rootstock to induce a more dwarfing effect on the vigor of the pear tree. The true quince is often confused with its distant relatives the oriental quinces...
Raspberries 1
If aphids are present, spray with dimethoate, formothion or malathion in spring. An oil spray in winter gets rid of the over-wintering eggs. To prevent raspberry beetle grubs feeding on the fruits in summer, spray at dusk with malathion or derris when the first pink berry is seen. The most serious diseases of raspberries are viruses, which cause the leaves to become mottled or blotched and the canes to be stunted. Seek expert advice before destroying canes because the symptoms are similar to...
Training and pruning 1
The training and pruning of grapes are matters of critical importance. The main purposes of training are to keep the large, fast-growing vines under control, to facilitate care and harvesting, and to expose all parts of the plants to the sun. The purposes of pruning are to maintain vigorous growth, to provide new canes for the next year, and to limit the number of fruit-producing buds so that the vines do not produce too much small fruit of inferior quality. Various training systems are used...
The fruiting stage
Each summer The fruits are carried on spur systems on the horizontal arms. The spurs are formed by the summer pruning of laterals on the Modified Lorette System in exactly the same way as for cordons. Regard each arms as a horizontal cordon see pages 50-1 . Winter After a few years of fruiting, the spur systems may become complicated and should be simplified by removing clusters of weak buds and by cutting back some of the spurs to two or three fruit buds. 5 From July to September, train the...

This is left unpruned to repeat the cycle.
