How to Prune a Plum Tree

9Plum trees generally are pruned in a vase type format. That means what you want to do is encourage the growth of a fairly short trunk and then encourage three or four major branches to splay off the top of that trunk at about a forty-five degree angle.

Now this is generally accomplished in the winter. In fact the very best time to prune plums is in the very late winter right before bud break. Because at that time, the wounds that you create have less time in which they have to heal before the tree starts to resume growth.

Now a vase type arrangement is ideal for plums because it allows a great deal of sunlight to get to the interior of the tree and to get to the fruiting wood. And remember whenever you're pruning, whether it's a plum or any other deciduous tree, never ever leave a stump on the tree. You want to prune it right back to the next major, either to the trunk or to major branches.



A stump is a way that insects, disease and fungus can find their way into the tree. In addition to basic winter pruning, which I've just spoken of, you can also do some light summer pruning. For instance if you get over vigorous shoots, water sprouts or crossing or damaged branches, by all means take those out. However the major pruning, the major shaping of the tree should take place in late winter.  Happy growing !

Pruning Mature Apples and Pears

A good fruit tree should not make a good shade tree. However, when pruning is neglected, many apples and pears become better shade producers than fruit producers. Standard-sized trees often outgrow the reach of ladders or pruning hooks. Backyard and commercial growers have come to prefer dwarf or semi-dwarf trees which are not as tall and are easier to prune, spray, and harvest without the use of ladders.

A neglected but otherwise healthy tree will usually show a marked improvement in fruit quality as a result of pruning. Fruit buds begin developing in the growing season previous to the one in which they mature into fruit, and more are initiated than can be fully developed into fruit. Growing conditions during the season of bud initiation and the subsequent winter will affect the number of buds which flower, and certain cultivars are "alternate bearers" that seldom initiate many buds during a year with a heavy fruit crop. In any case, by late winter the buds for the coming summer's crop will be very evident. Buds only appear on two or three year-old twigs or spurs which are no thicker than a pencil.

The primary purpose of pruning is to increase sunlight penetration, remove less productive wood, and shape the crown into an efficient, stable form. If left unpruned, the quantity of fruit produced might be greater, but the quality much lower. Pruning increases fruit size, promotes uniform ripening, increases sugar content, and decreases disease and insect problems by allowing better spray coverage and faster drying following rainfall. It also allows easier access for timely harvesting.
