IN THE ORCHARD From page 39 grow, which should generally be outwards. Different varieties of fruit trees have different requirements. To prune, it is also important to know how a tree fruits. For example peaches fruit only on shoots from last year's growth on both laterals and fruiting shoots, while in plums fruit is borne on laterals or spurs that are two years or older. On young trees the spurs look more like a group of short laterals and on older trees like multiple buds. K Peach trees Pruning methods for peaches and nectarines are very much the same. Pruning a peach tree opens up the tree and allows sunlight to shine on the fruit. This is important for healthy fruit production. Also, if you're going to spray your trees for diseases or pests, an open tree helps with equal coverage. Peach twigs can be killed in one growing season by too much shading. If there's too much shade, eventually no fruiting wood will be present in the lower part of the tree. Imagine what your hand looks like when holding a giant peach. When pruning peach trees, the shape of your hand is very similar to the shape of the pruned peach tree. The centre is open with about five main branches angling upward at 45 degrees. Each one of these main branches holds another hand. This second hand is what carries and bears fruit. You want to keep your tree short, so stand on the ground and crop the branches as high as you can reach with the clippers. If you have a tall limb where the only new growth is high above your head, cut off the limb. By keeping the tree low year after year, you'll encourage the tree to send out side branches instead of tall branches that reach to the sky. It's a lot easier to prune, pick and care for a low growing peach tree than a tall one. Choose four to six branches that come off the trunk. If there are branches growing What a pruned fruit tree should look like: Above: side view. Below: viewed from up the centre of the above. tree, prune these out. Looking at an aerial view of the tree, the area where the fruit and leaves grow looks more like a doughnut than a ball. Now you're going to trim up the remaining limbs, starting with any branches that are growing horizontal and downward.

In its In any one pruning you second season, cut back new should aim to remove about growth halfway on the five to two-thirds of the previous nine chosen lateral branches. season's growth. Continued on page 42 K Plum and Apricot trees The trick with plum and apricot trees is to shape them from when they are planted. When you first plant a plum tree, it is important to direct its growth and create a vase shape, keeping the centre open to let in the light. Prune the tree to five to nine wellspaced lateral branches away from the tree's centre. Branches coming off the side of the shoot are known as laterals and should be left as they produce the spurs for fruit. This will help to establish a solid foundation for future growth.
