The Bonsai Propagation Plants are able to
propagate both by sexual way, through the union of male and female
cells that bring to the production of seeds, and by asexual way,
i.e. from parts of the same vegetable. Layer: it is the
best method to obtain valuable bonsai trees with large trunks (up to 30-40
cm diameter). It is used with conifers, such us Junipers, Yews and
Pines, as well as with deciduous trees, such us Beeches, Figs,
Apples and Zelkovas. This operation consists in let new roots grow on the
trunk or branch part you want to use. The most suitable period is February
for European trees and May for tropical species, when there are the
perfect light, humidity and warm conditions. After making a deep round
cutting along the whole bark, you apply a certain amount of sphagnum on
the wound and wrap it with plastic film; as covering you use silver
paper, which will assure dark for the growth of the new little roots.
You have just to change the silver paper at intervals to check the growth
stage. After a period, which can vary from 2 months for a fig to 2-3
years for a conifer, you will remove the new plant and pot it. You can
use this technique also to improve a tree nebari. In this case you will cut
the bark just beyond the soil level. So radial roots will grow and
thicken as years pass. Cutting: in this
case the trunk or the branch are directly cut off and
put in a pot to root. Wooden cuttings allow obtaining even impressive
specimens in a short time, but they are suitable just for species having
great germinative capacity from dead wood, such as Olives, Phillirees,
Bouganvillaes and Figs. You have to remove all the vegetation,
which would lack nourishment, in order to help the tree use its energetic
reserve for the new roots. Green wooden cuttings are good for deciduous
trees and conifers and are very common in Juniperus chinensis cultivation
to get soft-needled trees. In this case you will use a soft twig with a
tuft of needles on its top. To help the birth of new outside roots, you
can use powdery or liquid hormones and put the plant into its pot. Sucker: this term
refers to a bud developing at the trunk base; you can use it as
a new root if you put it into the soil, or as a new tree, once
you have kept it from its mother-plant. Olives and Figs are good producer
of suckers.
