Expert tips
The key tip
Genista hispanica demands poor, very well-drained soil and hot exposure. A garrigue plant that hates heavy limestone and dampness.
The common mistake
Growing it in rich, moist soil produces a soft plant with sparse flowers and winter sensitivity.
The pro's trick
After flowering (June), lightly trim to densify growth.
Care
Exposure
Spanish broom demands full sun for abundant flowering and compact growth. Plant it in a spot sheltered from cold winds if possible, though it's quite hardy. It tolerates light shade, but flowering will suffer.
Watering
Undemanding for water once established, this broom prefers dry conditions. Water moderately at planting and during prolonged droughts. Avoid excess moisture which promotes disease and root rot.
Soil Preparation
Choose light, well-drained and low-fertility soil. Poor or chalky soil poses no problem. Improve drainage if soil is heavy by adding sand or gravel. Avoid overly wet or compacted ground.
Pruning and Maintenance
Prune lightly after flowering to maintain a dense, well-branched bushy form. Remove dead or poorly positioned branches. Avoid severe pruning which could weaken the plant and reduce future flowering.
Fertilizing
Undemanding, Spanish broom needs only moderate feeding. Apply balanced fertilizer in spring if soil is very poor. Excessive nitrogen promotes foliage at the expense of flowering.
Diseases and Pests
Generally robust and not prone to disease. Overly wet soil can cause rot. Watch for aphids if the plant is water-stressed. Good air circulation and optimal drainage prevent most problems.
Did you know?
Spanish broom is a true master of spring flowering: its tiny, brilliant yellow flowers completely blanket the bush in an explosion of color. This generous flowering has made broom a classic in Mediterranean gardens for centuries, prized for its hardiness and ability to flourish even in poor soils where few plants thrive.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
