Quick Reference: These are semi-succulent (e.g., H. kerrii). They require intermediate temperatures and must dry out almost completely between waterings. Overwatering is the #1 killer.
Quick Facts Summary
- Growth Habit: Climbers with thick, hard, succulent-like leaves.
- Light: High light. They can tolerate (and enjoy) some direct morning sun to maintain leaf shape.
- Water: Drought tolerant. The soil should dry out 80%–100% before watering again.
- Optimal Temp: Intermediate. 18°C – 28°C (65°F – 82°F). They tolerate household room temps perfectly.
💧 Watering & Rot Risk
- The "Taco Test": Do not water until the leaves are slightly pliable (like a soft taco shell). If the leaf is rigid, do not water.
- Rot Risk: These species are highly prone to root rot if kept wet. Use a very chunky, porous mix with extra perlite or bark.
☀️ Light & Growth
- Light: Give them the brightest light possible without scorching noon sun. Low light will result in leggy vines with large gaps between leaves.
- Growth Speed: They can be slow starters. Be patient—once established, they are vigorous growers.
