The yellow jasmine - general information
In the language of flowers, yellow jasmine indicates gentleness and elegance. Indeed, although small and inconspicuous, the flowers of this shrub stand out for their bright color and unusual flowering season. Yellow jasmine was discovered in China and introduced to Europe in the mid-1800s by a Scottish botanist; since then, its popularity and diffusion have grown thanks to its resistance to cold climates and its rusticity, which allows it to grow with very little care. Its versatile nature allows it to be used to border flower beds, as a ground cover, or to use it to cover walls or parapets - in this case the plant must be provided with support. The small shiny leaves appear in spring, after flowering, gathered in tufts of three leaflets.
This plant is considered a rustic shrub, which requires little care and fits well in all climates, requiring no special attention. With regard to the soil, this plant adapts to any soil, even poor in organic matter; the newly planted shrub needs regular watering, so that its roots take root and develop easily; subsequently, it will settle for rainwater. If placed in a sunny position, the plant will give rich blooms, while in the shade the leaves will develop more. Furthermore, the particular resistance to smog and the ability to reduce noise pollution, thanks to the dense foliage which forms a barrier against external noise, make the flower ideal for city balconies and terraces. It is therefore excellent to give liveliness and color to our homes and bring a bit of green even to the city!
Pruning and reproduction
The pruning of the plant will be carried out at the end of flowering, in the months between March and April, before the leaves sprout on the branches. Light annual pruning will prevent the branches from growing excessively untidy and will contribute to the development of more leaves. To promote healing and, at the same time, avoid infestations, this operation must be performed with special and very sharp scissors, with which oblique and clean cuts will be made. As for the reproduction, it takes place by cuttings, of about 10-15 cm, to be taken in autumn and put to root in a mixture of sand and peat in equal parts. The seedlings thus obtained must be kept sheltered for 2 years and subsequently transplanted to facilitate their growth.
Yellow jasmine: Pests and diseases
The yellow jasmine it is exposed to attacks by two of the most common plant parasites: aphids and cochineal. Aphids: they live in colonies that enlarge quickly, sucking the sap of the plant which, consequently, perishes. A plant infested with these parasites has, on the underside of the leaves, clusters of small mobile, whitish or yellowish insects. They fight with specific pesticide treatments. Cochineals: these insects also feed on the plant sap; their presence is revealed by whitish spots on the underside of the leaves, which dry up, crumple and fall off. If the infestation is contained, the scale insects can be removed with a cotton swab soaked in alcohol; if, on the other hand, the invasion is extensive, it will be necessary to resort to pesticides.
