Care
Light exposure
Garden spurge prefers a sunny to partially shaded location. It tolerates full sun well and adapts to less bright spots, but will flower more generously in full light. Avoid heavily shaded areas to maintain balanced growth.
Watering
Water moderately, letting the soil dry out between waterings. This plant tolerates drought well and fears excess moisture, particularly in winter. Avoid wetting the foliage to prevent fungal issues.
Soil and drainage
Plant it in well-drained, light, rather poor soil. Soil that's too rich encourages vegetation at the expense of flowering. Amending with sand or perlite improves drainage if your soil is heavy.
Fertilizing
A light application of balanced fertilizer in spring is plenty. This frugal plant doesn't require regular feeding. Avoid excess nitrogen, which slows flowering.
Pruning and maintenance
Pinch young plants in spring to encourage a more compact, bushy shape. Remove faded flowers regularly to extend blooming. At season's end, leave a few flowers to set seed if you want natural reseeding.
Pests and diseases
Garden spurge is generally resistant. Watch for aphids and whiteflies in case of attack. Powdery mildew may appear in very humid conditions: ensure good air circulation and reduce leaf moisture. Chemical treatment is usually unnecessary for small pest populations.
Did you know?
Garden spurge owes its scientific name Euphorbia to Euphorbus, a physician from Numidia in antiquity. This plant is remarkable for its seed dispersal system: at maturity, its capsules contract abruptly and project seeds at a distance, allowing it to rapidly colonize gardens and vegetable patches—earning it the nickname of an opportunistic "weed" in horticulture.
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.
