How to Grow and Care for Euphorbia guiengola
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 require 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 guiengola 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. However, 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.
