August 12, 2017 17:52 | Fruit Plants

Many gardeners are interested in the problem of reducing the crown of the apple.Indeed, the harvest with 15-20-year-old apple trees becomes a problem.So often buy trees on dwarf rootstocks.But the dwarf rootstock root system, firstly, does not have the right to our region hardiness, and secondly, can not feed silnorosly scion, so that winter hardiness and productivity of trees is not worth the area occupied by them.Much better if silnorosly stock with a strong root system first grafted Paradizku (dwarf scion), and two years later grafted silnorosly, yielding variety on it.That is, do the insert from the dwarf.

But the wisdom to anything: Apple - very plastic plant, it allows a haircut, including the reduction of the crown.Just starting from the moment when the center conductor has reached 2 m in height, cut the end of his year in the fall, leaving no more than 2-3 cm of new growth, and accordingly cut the end of all the branches below the conductor, growing up.They should be less than 12-15 cm conductor

, or try to take his place.Do not forget to lubricate the seat trim Zelenko.She cleans the wound, but will leave the living cambium cell boundary.Rank gradually overgrown bark.From the nearest to the kidney slice will the new Escape, which will be the guide, and you shorten it again, and so on.If the tree has outgrown all reasonable limits, just autumn Spila him the crown, the cut is not just grease green paint, but also from top to seal the liquid garden pitch or oil, natural paint.A downstream branch cut so that they are below the central truncated trunk 12-15 cm Once again:. Apple is very plastic plant (which is not true of a pear), and therefore easily tolerates pruning and crown pruning apple trees can give the most diverse form.Such trees with artificial crown shape is commonly called, shaped apple.
