Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours/day). Tolerates partial shade but blooms best in direct light.
Sunlight Tolerance Tips:
Acclimate gradually if moving from shade to sun; protect from intense midday heat in summer; ensure good air circulation to prevent fungal issues.
Care Requirements
Care Difficulty
easymoderate
Sunlight
full sun
Avoid sudden light changes; use shade cloth in extreme heat; rotate plant for even exposure.
Watering
every 7–10 days during active growth, less frequently in winter
Water deeply but infrequently; avoid overwatering; ensure excellent drainage.
Soil
well-drained, rocky, alkaline soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure soil dries between waterings; avoid heavy clay soils; amend with grit if needed.
Temperature
Prefers warm temperatures (65–85°F/18–29°C). Tolerates mild frosts but thrives in heat.
Protect from frost; water deeply in heat; adjust care seasonally.
Fertilizing
every 2–3 months during spring and summer
Fertilize sparingly; avoid high-nitrogen formulas; stop in winter.
Propagation
Methods
Stem cuttings taken in late spring or early summer.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Dip in hormone.
- Plant in medium.
- Keep moist and humid.
Best Time: Late spring to early summer when new growth is present.
Environment
Warm (70–75°F/21–24°C), high humidity (70–80%), and bright indirect light.
Medium
Well-draining mix of perlite and peat moss or cactus mix.
Hormone
Recommended to use rooting hormone for better success.
Timeline
Roots in 4–8 weeks; establish in 3–6 months.
Tools Needed
Pruners, rooting hormone, small pots, misting spray bottle.
Quick Tips
Use healthy, non-flowering stems; maintain humidity with a propagator; avoid direct sun.
Pruning & Repotting
Pruning Guide
Method
Selective thinning and heading back to promote branching.
Pruning Plan
Prune to maintain shape, encourage bushiness, and remove dead/damaged growth.
Tools
Sharp bypass pruners, pruning saw for larger stems.
Checklist
Disinfect tools; prune before flowering; remove dead wood; shape evenly.
Repotting Guide
Best Season
Early spring before active growth begins.
Pot Size
One size larger pot (e.g., +2–3 inches in diameter).
Method
Use fresh, well-draining soil; trim any circling roots; ensure pot has drainage holes.
Suggestions
Repot only when root-bound, typically every 2–3 years. Prefers slightly root-bound conditions.
Checklist
Check root crowding; use fresh soil mix; trim roots if needed; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; ensure drainage; adjust for season.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone without wetting foliage. Water early in the day to minimize evaporation and fungal risk.
Watering Schedule Tips
Water sparingly, allowing soil to dry between waterings. Reduce watering in winter to match dormancy.
Soil Improvement
Add perlite or coarse sand to improve drainage; incorporate compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis, leaf drop, or stunted growth in cold; wilting or scorching in excessive heat.
Cold Stress
Slows growth, may cause leaf drop or dieback in prolonged cold below 20°F (-6°C).
Solution: Provide frost protection in winter; plant in a sheltered location; avoid overwatering in cold.
Hot Stress
Leaves may wilt, scorch, or drop if exposed to extreme heat without adequate water.
Solution: Water deeply during heatwaves; provide afternoon shade; increase humidity around the plant.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; apply during active growth; avoid winter feeding.
Fertilizing Method
Use a balanced, low-nitrogen fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer). Avoid fertilizing in fall/winter.
