Tips

Robinia

Irrigation

The admirable tree comes exclusively from the north of the American continent and is classified in the relevant and varied family grouping of the Fabaceae. This ornamental and long-lived plant stands out for its thick and shiny foliage and above all for the aesthetic and perfumed inflorescences, with candid, pink or reddish hues. Resistant and vigorous, it will be adequately sprayed only in the spring and summer seasons, especially in the presence of torrid or sultry heat, while watering will be limited during cold periods or even suspended, if the climate turns out to be rainy. The advice, in any case, is to water the Robinia sparingly and only when the soil has dried up or dried up, in order to avoid possible damage to the structured roots.

Cultivation


The graceful Robinia will find an easy place in the embellishment of any type of open space, both rural and urban. Although capable of surprising adaptation, the tree will prefer a soft earth, slightly moistened and equipped with sufficient organic substances and efficient drainage. The thickness and depth of the chosen soil will also be very important, since the root system is very vigorous and must not find obstacles in its tumultuous growth. Periodically, at least every two years, the ornamental plant will be subjected to pruning operations, aimed primarily at modeling the shapes and posture. The work, however, must properly include the removal of all the now torn and old parts and of the withered inflorescences.

Fertilization


Regardless of the space chosen for the placement, the imposing tree will be moderately fertilized, in order to obtain the right and correct nutrients. Fertilization will normally be carried out in spring and autumn, with not too high frequencies. It is highly advisable to use fertilizer of a solid nature, granular with progressive and deferred transfer, possibly organic with a letamic texture. The fertilizer must be specific for green plants and contain a significant prevalence of potassium and phosphorus elements, to which must be added the necessary and necessary microelements, among which the ferrous component will stand out. Alternatively, liquid fertilizers can also be used, to be used with shorter times after having dissolved them in the spraying water.

Robinia: Exposure and pathologies


This rustic plant will adore a fully sunny and illuminated habitat, with direct exposure to solar radiation, nevertheless it will adapt with ease to partially or even significantly shady environments. It will not suffer any kind of adverse climatic conditions, nor generally the abrupt and sudden flows of air. Finally, the ornamental tree may not rarely be attacked by numerous insects and parasites, among which the cochineal is highlighted. It will be necessary to remove unwanted guests on the occasion, using a specific biological product or a suitable chemical insecticide. Another possible pitfall will be represented by various fungal diseases, all attributable to environmental conditions and easily remedied through the use of biological aids.
