Care
Exposure
Ononis pusilla prefers a sunny exposure for abundant flowering. It tolerates light partial shade but flowers less generously in these conditions. Make sure to give it at least 6 hours of direct sunlight daily for optimal results.
Soil and drainage
This plant appreciates well-drained soil, even poor or stony soil, characteristic of Mediterranean environments. Avoid heavy and overly humid soils that promote root rot. Light, even sandy soil suits it perfectly.
Watering
Water moderately and wait for the soil to dry on the surface between waterings. Once established, Ononis pusilla is fairly drought-resistant. In winter, reduce watering, especially in cold weather. Avoid waterlogging which promotes fungal diseases.
Fertilization
Fertilizer is generally not necessary. As a legume, it naturally enriches the soil with nitrogen through root symbiosis. In very poor soil, a light application of balanced fertilizer in spring can stimulate growth and flowering.
Pruning
Perform light pruning after flowering (September-October) to maintain a compact shape and encourage branching. Remove dead or damaged stems. Avoid severe pruning that can weaken the plant.
Diseases and pests
Ononis pusilla is generally robust. The main problems are root rot if there is excess moisture and occasionally aphids. Ensure optimal drainage and regularly inspect the foliage to detect any pests early.
Did you know?
Ononis pusilla is part of the plants called 'butstop' due to its spiny stems that easily catch on clothing and animal pelts. This seed dispersal strategy earned it this picturesque nickname in traditional Mediterranean agriculture, where it grows spontaneously in fields and pastures.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
