Always remember to wait for the soil to be dry before proceeding with a new watering, because wet soils are poorly tolerated by this type of plant.
They do not need fertilization, the roots of the ginestrone live in symbiosis with nitrogen-fixing bacteria: these plants are often used to enrich very poor soils.
This variety of plants grow in any well-drained soil; they prefer calcareous, even stony or sandy soils; they do not like excessively compact or too humid soils. For this reason, it is advisable to check that the base of the plant does not form stagnations of water, which could affect the health of these specimens.
As far as the multiplication of this kind of shrub is concerned, it usually takes place by seed; plants produce small pods containing 4-5 seeds; when ripe, the semi-woody pod explodes, releasing the seeds, which are easily found around the plant.
