The right month to multiply evergreen shrubs to be used as a hedge is August. Late summer, heat and refreshing thunderstorms in fact offer the right conditions to obtain the cuttings of essences such as abelia, aucuba, berberis, cotoneastro, cherry laurel, evonimo, lavender, lonicera and skimmia.

In the case of evergreen shrubs, the taking of the cutting for the multiplication must be done during the crescent moon, that is when the curved part is facing west (hump to the west). This is because the flow of the sap favors and increases the chances of engraftment.

The branches to be used as cuttings must be cut from the mother plant with a sharp knife, taking care to take even a small portion of the tissues from the main branch (the so-called heel). The lower leaves of the cutting must be removed, while the leaflet of the intermediate ones must be halved. Only the leaves at the apex should be left intact.

Procure the cuttings, they should be planted in boxes about 15 centimeters away from each other, taking care to do so in a rather loose soil. Future seedlings should always be kept cool and with the base slightly damp, but away from stagnant water that would favor the formation of mold and mildew.

The rooted cuttings of the evergreen shrubs they can be potted in the spring of the following year and grown in pots for about a year. Or they can be immediately planted in the ground and pruned regularly to make them branch and strengthen. Within a few years, they will form a thick, lush hedge.

The evergreen shrubs that we have cited can be reproduced with the same system, even if they have very different characteristics in some cases.

Abelia. It is a family of evergreen shrubs where the variety only grown in the garden is a hybrid of species originating in China. In some years it reaches a height and width of 100-120 centimeters. Dark green leaves, new bronze colored leaves, white-pink flowers in summer.

Cotoneastro. Originally from China and the Himalayas, they are evergreen shrubs of many species, large with deciduous leaves, and dwarfs. Cotoneaster horizontalis originally from western China reaches a maximum height of one meter. Herringbone branches, dark green leaves and red berries that stay long in winter.

Berberis vulgaris. is an evergreen shrub of the Berberidaceae family. Deciduous leaf, with sturdy thorny branches, it grows slowly until it reaches a maximum height of 3 meters. The leaves come out in mid-March, and the flowers are born between May and June and, from August until October, red berries sprout about one centimeter long.

Cherry laurel. The specific name derives from laurus (laurel) and cerasus (cherry) due to the similarity of the leaves. It is a fast growing shrub-tree that can reach 7 meters. The leaves are dark green and the flowers are white (flowering April-June). The fruits are drupes of about 1 centimeter, red-purple when unripe and black-bluish when ripe. Leaves and fruits contain hydrogen cyanide and are poisonous to humans.

Cotoneastro. Native to China and the Himalayas, they are evergreen shrubs of many species, large with deciduous leaves, and dwarfs. Herringbone branches, dark green leaves and red berries that stay long in winter.
