in what period the layering is made for the apple tree
layering generally takes place in spring, in March or April; in this period in fact the plants are in full vegetative development, and therefore the possibilities are greater that the layering rooted. In general, before preparing an air layering, it is good to carefully choose the branch on which to lay it; in fact it is advisable to choose a branch very well developed and branched, healthy, and possibly with few (or even without) flowers or fruits, in this way you will be more certain of the fact that the layering can develop by itself, once detached from the mother plant . A layering is prepared by carving the bark in the desired point, making a circle all around the branch; then it spreads out of the rooting hormone, and covers itself with damp soil, to form a sort of "vase", precisely at the point where the bark is engraved. It is covered with plastic film, so that the earth does not dry out; possibly the film should be opaque, so that the earth does not receive too much direct sunlight. The layering takes months before taking root (in some cases even years), for as long as necessary you will have to water the ground bread, so as to prevent it from remaining dry for a long time, and checking that the plastic film does not come off. You can also water the earth with a syringe, if you want, so you don't have to open the package you keep around the base of the layering too often; to stop the package you can use thread for bonsai, raffia, laces, whatever you want, as long as the whole is well attached to the branch you intend to lay. You can be sure of the success of your operations only when you see roots inside the earthen bread. To remove the layering from the mother plant it is good to wait until autumn.
