You may want to mark branches with string or tape so you don’t forget where you had planned to prune each branch. It is a good idea to identify which branches you want to prune before taking other steps so you know which tools you need and have a plan from the beginning. Even if the number of leaves with infections is relatively large, you should not prune more than 30% of the total number of leaves to avoid affecting the growth of Spanish broom. Pruning can effectively reduce the infection of disease. When Spanish broom grows, if there is aging yellowing leaves and diseased leaves, you need to prune the bottom of the yellowing aging leaves and leaves with spots caused by the infection of disease. Please make sure that the cuts are clean and tidy. Over pruning will hinder the normal and healthy growth of this plant. You can also prune it into a shape you like, but don't prune over 1/4 of the healthy branches and leaves of the Spanish broom. Pruning at the beginning of the growing season allows the Spanish broom to have the whole summer to devote to putting new growth into the remaining branches, flowers, and leaves. This timing makes it easy for you to find which branches are not productive and should be removed, since those branches won’t have any buds. The ideal timing is when the Spanish broom has developed buds but the buds have not opened yet. dissertation.Removing large branches (structural pruning) from the Spanish broom is best done during the dormant period in the winter, while late winter or early spring is the best time for minor maintenance pruning.

The linear pods are 5-10 cm long, more or less strigose, compressed, and many seeded. The stamens are monadelphous (united by their filaments forming a tube around the gynoecium). This may be contrasted with the two-lipped calyx of Cytisus monspessulanus. The calyx is split above, hence one-lipped, with 5 minute teeth. The banner and keel are longer than the wings, and the keel is pubescent along its lower edge. The fragrant yellow flowers are borne in loose terminal racemes, unlike those of Cytisus scoparius which are usually solitary in the axils. The oblance-oblong or narrower leaves are 1-3 cm long. The alternate leaves are simple, entire and more or less strigose, having short petioles. The shrub is virgately branched and contains no spines, unlike gorse ( Ulex europaeus). Spartium junceum is a perennial shrub, up to 3 m high, with long, slender, leafless or few-leaved, green, rushlike branchlets. General Description:The following description of Spartium junceum is adapted from Munz and Keck (1973). Dry summer plants create a severe fire hazard. Like other broom species, it offers strong competition to other plants and contributes to increased maintenance costs on lands where it becomes established. junceum is adapted to dryer sites where its lack of leaves and thick waxy stems resist dessication. Fruit Seeds can remain viable in soil for more than 80 years. Flowers The fragrant yellow flowers are borne in loose terminal racemes, unlike those of Cytisus scoparius which are usually solitary in the axils. Foliage Spanish broom has long, slender, leafless or few-leaved, green branches. Native Range: Meditteranean region & Canary Islands ( REHD) Īppearance Spartium junceum is a perennial shrub, that can grow up to 9.8 ft.
