FOR MARGOTTALayering is a type of reproductionwhich occurs in plants where multiplication by cuttings does not give good results or when you want to recover old or damaged plants, with the certainty of obtaining results.
Ficus elastica, magnolia etc. are propagated with this technique.
The best time to achieve it is late spring-early summer, when the plant is in full growth.We proceed in this way: o by making a shallow incision from bottom to top along the length of the stem or branch of about 10 cm in length and 0.5 cm in depth, along an internode
or an annular incision can be made by removing a ring of cortex about half a centimeter high.
In both cases,once the incision is made, the cut area is brushed with rhizogenic hormones that promote rooting and, in the case of an oblique incision, a piece of wood is placed inside the wound or moist sphagnum to prevent the cut from closing.
Once this is done, the wound is wrapped with moist sphagnum (and it must remain so for the entire time of rooting) and cover everything with transparent plastic, closing the two ends with string so that the final appearance is that of a sausage, to avoid the loss of humidity.
Periodically, the plastic is removed to check if the sphagnum is wet and, if necessary, action is taken.
After a variable number of months from plant to plant, the roots will begin to form and only after they are well developed, the portion of the rooted branch will be cut and planted in a pot in the same soil as the adult plants and as such they must be treated.
