Everything it needs
9 essentials at a glance
Watering
Euphorbia obesa prefers to dry out between waterings.
Water thoroughly when the top 1-2 inches of soil feel dry, typically every 2-4 weeks during the growing season (spring and summer). In fall and winter, reduce watering to once every 4-6 weeks. Signs of over-watering include yellowing or mushy stems, while under-watering may cause shriveling or browning of the plant.
Light
This plant thrives in bright, indirect light but can tolerate some direct sunlight.
Ideally, place it near a south or west-facing window where it can receive 4-6 hours of light daily. Too much direct sun can scorch the plant, while insufficient light may lead to leggy growth.
Soil
Euphorbia obesa prefers a well-draining cactus or succulent potting mix, ideally with a pH range of 6.0 to 7.0.
A mix of potting soil, sand, and perlite or pumice in equal parts is recommended to ensure proper drainage and aeration.
Humidity
This plant prefers low to moderate humidity levels, ideally around 30-50%.
To increase humidity, you can place a humidity tray filled with water and pebbles beneath the pot or use a room humidifier. Signs of low humidity stress include browning leaf tips or stunted growth.
Temperature
Euphorbia obesa thrives in temperatures between 65-80°F (18-27°C) and is hardy in zones 9-11.
It can tolerate brief periods of cooler temperatures down to 50°F (10°C) but should be protected from frost and extreme heat.
Fertilizing
Use a balanced, diluted liquid fertilizer with an NPK ratio of 10-10-10 during the growing season, applying every 4-6 weeks.
In fall and winter, refrain from fertilizing. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Pruning is generally not necessary for Euphorbia obesa, but you can remove any dead or damaged stems with sterilized pruning shears.
If the plant becomes too large, you can trim it back lightly in spring to maintain its shape.
Repotting
Repot every 2-3 years or when the plant outgrows its pot, typically in spring.
Choose a pot that is 1-2 inches larger in diameter. Signs it needs repotting include roots growing out of the drainage holes or stunted growth. To repot, gently remove the plant from its pot, shake off excess soil, and place it in fresh potting mix.
Propagation
Propagation can be done through stem cuttings or offsets.
For stem cuttings, cut a healthy stem, allow it to dry and callous for 1-2 days, then plant it in well-draining soil. Offsets can be gently removed from the parent plant and replanted. The best time for propagation is during the spring.

Summer
During summer, continue regular watering and ensure the plant receives adequate light. Monitor for pests and provide good air circulation.
Fall
In fall, gradually reduce watering as the plant enters dormancy. Stop fertilizing and prepare for cooler temperatures.
Winter
In winter, water sparingly, allowing the soil to dry out completely between waterings. Keep the plant in a warm location away from drafts.
