Euphorbia Milii is one of the most popular Euphorbias. It grows into a small thorny shrub which branches dark brown stems with sharp spines. Flowers are tiny but each is surrounded by a pair of kidney-shaped bright red or yellow bracts which look like petals.
Start watering in Spring fortnightly through Spring and Summer. In hottest months water weekly, but allow to dry out between waterings. After the flowering season ends, give less water. Never let the roots dry out completely for dry roots cause premature leaf-fall.
Apply standard liquid fertilizer every 2 weeks from late Spring to early Autumn. Feed once a month if plants continue to flower during the winter.
Move plants into pots one size larger in early Spring every second year.
Use a sharp knife and gardening gloves, cut off growing tips 3 or 4 inches long in Spring or Summer. Stop latex flow immediately by spraying the old plant and dipping the cuttings in water. Allow cuttings to dry out for a day before planting them in small pots containing moist equal parts mixture of peat moss and sand or perlite. Place the pots in bright light at normal room temperature.
A Sunny position is needed for best results. The brighter the sunlight, the longer its flowering season will be.
All parts of Euphorbias are poisonous and you should always bear this in mind if you cut or scratch yourself on a crown of thorns. Never allow the sap of the plant to get inside the wound, it is an extreme irritant and dangerous to the eyes.
Unlike many succulents, Euphorbia can become dehydrated if it is allowed to dry out.
Decorate on a windowsill well away from where it could be a hazard.
Cactus and succulent compost.
