Euphorbia baioensis is a small succulent that forms a shrub with greyish-green upright or decumbent stems. It is mainly branched from the base. Stems are cylindrical, up to 1 foot (30 cm) long, and up to 0.4 inches (2 cm) in diameter. They have 8 to 10 ribs with a pair of spines on each spine shield.

How to Grow and Care for Euphorbia baioensis

Light: Most Euphorbias are sun lovers, but some will tolerate partial shade. Place your indoor Euphorbias on windows with southern or southeastern exposure.

Soil: Euphorbias requires well-drained soil. They even thrive in poor, dry soils. Use a commercial mixture formulated for cacti and succulents or make your own potting mix.

Hardiness: Euphorbia baioensis can withstand temperatures as low as 35 to 50 °F (1.7 to 10 °C), USDA hardiness zones 10b to 11b.

Watering: Succulent Euphorbias can survive drought, but do not mean that they need it. From spring to fall, water when the top inch of soil feels dry. Reduce watering in winter, give them just enough water to prevent wilting.

Fertilizing: Every Euphorbia will benefit from fertilizer. Apply a balanced fertilizer in a 10-10-10 NPK formulation, diluted to 1/4 strength once a week during the growing season.

Repotting: Euphorbias do not need to be repotted every year. When your Euphorbia is outgrowing its pot, it is time to repot the plant in a larger pot and give it a fresh potting mix.

Propagation: The easiest and fastest method of propagation for many species is by using cuttings. Euphorbias can also be grown from seeds, but they can be difficult to germinate, even hard to find.
