Fertilization in the Bonsai Ligustrum must be carried out during the vegetative state, with the exception of the hottest period from mid-July to mid-August, the frequency of interventions depends on the need to integrate the nutritive elements, as it can quickly decrease according to the size of the plant. root system. It is preferable to use liquid fertilizer added to the water, even if the powdered one is absorbed more slowly. Wet the plant before fertilizing.PRUNING STICKING, WIRE AND TIE RODS
There are two types of pruning, that of training to give the Ligustrum Bonsai a well-defined shape, usually it is done during the vegetative season, until the end of August, the branches must be pruned with well sharpened and disinfected shears for a clean cut without fringing so as not to damage the plant and subsequently be treated with mastic or healing paste, also useful for keeping animal parasites away. Finally there is the maintenance one which is used for the correction of branches that do not have a habit, broken or sick branches and can be performed at any time of the year. During the whole vegetative season it is necessary a constant pinching of the new foliage with the use of scissors for the cutting of the leaves, this technique must be performed only on the shoots that have reached 5-6 pairs of leaves, cimadano to two pairs.
The wires and the tie-rods are not much loved by the Bonsai Ligustrum so it is advisable to carry them out only if strictly necessary and remove them promptly before they affect the trunk and branches. The wires are made of copper, easy to bend and are wrapped with rubber material so as not to mark the plant during assembly, the tie rods instead are usually fixed directly to the vessel. This operation is performed during the vegetative season, on young branches, which are more elastic and flexible and easy to shape, it is advisable to water the plant an hour earlier to make the branches even more manageable, preventing them from breaking and creating a Bonsai trauma.
In the Bonsai Ligustrum the repotting technique must be performed during the vegetative growth period, towards the end of spring and early summer, every 2-3 years. Important is the choice of the vessel that must have the right size according to the plant and must allow aeration and oxygenation to the substrate and therefore to the radical mass, the substrate must ensure a good drainage and preferably be composed at 50% of universal soil, at 25 % peat and the remaining 25% from sand. Before inserting it in the vase, it is advisable to place a grid or gravel on the drainage holes to prevent water from dragging away part of the soil and finally it is useful to block the passage to animal pests. It is also necessary to intervene on the radical mass, intervening on the thicker and more woody roots, leaving room for those more capillaries that serve for the nourishment of the plant.
Bonsai ligustrum: PARASITES
The most fearsome animal pests for the Ligustrum Bonsai are the cochineals, the aphids and the moschini miners of leaves it is possible to intervene manually to remove them by spraying all over the foliage of the pine oil and subsequently eliminate the incrustations by brushing with a toothbrush, or after identifying the insect is possible to intervene with a chemical or biological insecticide, starting with a half dose and eventually increasing it later. The diseases that can damage it are the fungi, it is possible to treat them with fungicides to remove them completely.
