Care
Watering
Water moderately during the growing season, allowing the soil to dry between waterings. Reduce watering drastically in autumn and winter. Avoid standing water which causes root rot. This euphorbia appreciates dryness and will tolerate dry periods well.
Light exposure
Place the plant in full sun for optimal development. It also accepts partial shade situations, but will flower less generously. Ensure good light levels to maintain a compact and vigorous habit.
Pruning and maintenance
Prune lightly after flowering to encourage branching and maintain a balanced shape. Remove damaged or diseased stems in late winter. Wear gloves when handling, the euphorbia's latex can be irritating.
Soil and substrate
Prepare a very well-draining substrate by mixing garden soil, sand and gravel. Euphorbias fear winter moisture: favor light and aerated soil. In humid regions, grow in pots or slightly raise the planting.
Fertilizing
Apply balanced or low-nitrogen fertilizer once or twice during the growing season (spring-summer). Limit fertilization on already rich soils. Excess nitrogen promotes foliage at the expense of flowering.
Diseases and pests
Watch for powdery mildew in case of excessive humidity. Aphids may occasionally affect young shoots. The main risk remains root rot due to excess water. Ensure optimal air circulation and impeccable drainage.
Did you know?
Euphorbias have fascinated since antiquity: the ancient Greeks named this family after Euphorbus, physician to the king of Mauritania. The characteristic milky latex of euphorbias was once used in traditional medicine, although its skin toxicity is well documented. Euphorbia serrata, with its finely serrated leaves, embodies the ornamental subtlety of this botanically remarkable family of remarkable diversity.
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.
