Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; can tolerate some direct morning sun but avoid harsh afternoon sun.
Sunlight Tolerance Tips:
Acclimate gradually to brighter light; protect from intense midday sun; place near east-facing windows indoors.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
bright, indirect light; partial shade
Rotate plant weekly for even light; use sheer curtains to filter strong light; avoid direct afternoon sun.
Watering
every 7–10 days during active growth, reduce in winter
Water deeply but infrequently; ensure soil dries between waterings; avoid waterlogging.
Soil
well-draining, organic-rich potting mix
pH: Slightly acidic to neutral (pH 5.5–6.5).
Use a mix with good aeration; avoid heavy garden soil; ensure pots have drainage holes.
Temperature
Prefers 65–80°F (18–27°C); cooler temperatures (50–60°F or 10–15°C) at night can promote blooming.
Avoid sudden temperature changes; protect from drafts; maintain consistent warmth during active growth.
Fertilizing
every 2–4 weeks during active growth (spring to fall), none in winter
Fertilize after watering to prevent root burn; switch to phosphorus-rich fertilizer before blooming season.
Propagation
Methods
Stem cuttings
Step-by-Step Propagation Guide
- Cut a healthy stem segment.
- Let it callus for 1–2 days.
- Plant in moist medium.
- Maintain humidity.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–80%), warm (70–75°F or 21–24°C), indirect light.
Medium
Well-draining mix of peat, perlite, and sand or cactus mix.
Hormone
Optional but recommended for faster rooting.
Timeline
Roots in 3–6 weeks; establish in 3–6 months.
Tools Needed
Sharp knife, rooting hormone, pots, well-draining medium.
Quick Tips
Use a clear plastic bag to maintain humidity; avoid overwatering new cuttings.
Pruning & Repotting
Pruning Guide
Method
Cut stems just above a node or joint; avoid tearing the plant.
Pruning Plan
Remove dead or overgrown stems to encourage new growth and better flowering.
Tools
Clean, sharp pruning shears or scissors.
Checklist
Sterilize tools; cut at an angle; remove diseased or damaged stems.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
One size larger pot (e.g., +2–3 inches in diameter).
Method
Remove plant gently; trim roots if crowded; repot in fresh, well-draining soil with a slightly larger pot.
Suggestions
Repot every 2–3 years or when roots fill the pot; promotes better growth and flowering.
Checklist
Use fresh soil; ensure drainage; water lightly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water thoroughly; ensure drainage; avoid wetting foliage.
How to Apply Water Properly
Water at the root zone until water drains from the bottom, ensuring even moisture without saturating. Water in the morning to allow foliage to dry.
Watering Schedule Tips
Water thoroughly when the top inch of soil feels dry, typically every 7–10 days in spring/summer, reducing to every 2–3 weeks in fall/winter. Adjust based on humidity and temperature.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate organic matter for fertility.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, or bud drop in extreme heat; stunted growth or root rot in cold.
Cold Stress
Slows growth, causes leaf discoloration, and increases susceptibility to root rot.
Solution: Move to a warmer location; insulate pots; avoid cold drafts; reduce watering.
Hot Stress
Leaves may scorch, wilt, or drop; flowers may fade quickly.
Solution: Provide shade; increase humidity; water more frequently but avoid overwatering.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; apply during active growth; avoid winter feeding.
Fertilizing Method
Use a balanced liquid fertilizer (20-20-20) diluted to half strength every 4–6 weeks during spring/summer; cease in fall/winter.
