Baseball Plant

🌵 Euphorbia obesa Care Guide

Common Name: Baseball Plant
Botanical Name: Euphorbia obesa
Type: Succulent (not a true cactus)
Hardiness Zone: USDA 9–11 (frost-sensitive)
Growth Habit: Globe-shaped; grows up to 8 inches tall and 4 inches wide

☀️ Light
Bright, indirect light is ideal.

  • Outdoors: Partial sun or bright dappled light—avoid intense afternoon sun.

  • Indoors: A sunny windowsill (east- or south-facing) works great. Rotate regularly to keep its shape balanced.

💧 Water
Water sparingly—this plant is extremely drought-tolerant.

  • Growing season (spring/summer): Water when the soil is fully dry. About every 2–3 weeks depending on conditions.

  • Dormant season (fall/winter): Cut back drastically—once a month or less.

⚠️ Overwatering leads to root rot. Always err on the dry side.

🪨 Soil
Use a fast-draining succulent or cactus mix.

  • Add extra pumice or perlite if needed to ensure excellent drainage.

  • Avoid moisture-retaining soils or anything with peat moss.

🌡️ Temperature & Humidity

  • Prefers warm, dry climates.

  • Protect from temperatures below 50°F (10°C).

  • Humidity should stay low—avoid humid bathrooms or greenhouses.

🌱 Fertilizer
Feed lightly during active growth (spring and summer).

  • Use a diluted cactus or succulent fertilizer once a month.

  • Do not fertilize in fall or winter.

⚠️ Special Notes

  • Euphorbia obesa produces a toxic sap—wear gloves when handling.

  • It's dioecious: individual plants are either male or female.

  • Rarely offsets, so propagation is usually by seed.

  • Don't confuse it with similar round cacti—it’s a succulent, not a cactus!
