Care
Exposure
Place this wild asparagus in full sun or partial shade. It appreciates warmth and light for dense foliage and good branching. Avoid heavily shaded areas that would slow growth.
Watering
Water regularly during the first year of establishment to encourage rooting. Once well established, it tolerates drought and needs little water in summer. Reduce watering in winter.
Soil
Prefer light, stony, and very well-draining soil to prevent root suffocation. Chalky and poor soils are not a problem; add sand or gravel to improve drainage if needed.
Pruning and maintenance
Prune lightly in spring to maintain a compact shape and encourage branching. You can cut back to 20–30 cm after winter if the clump becomes overgrown. Remove dead or weak wood.
Fertilising
It needs little fertiliser. A light application of balanced fertiliser in spring is quite enough. On very poor soil, a layer of compost on the surface in spring will maintain good vigour.
Diseases and pests
This species is generally little affected by diseases. Watch out for root rot in case of prolonged excess moisture. Red spider mites may appear in very dry and hot conditions.
Did you know?
The sharp-podded asparagus (Asparagus acutifolius) has been used since Greco-Roman antiquity, not for its edible shoots (although some forms are edible), but as a medicinal and fodder plant. Its deep roots made it valuable for stabilising steep Mediterranean slopes, and it features in traditional North African and Levantine dishes.
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.
