Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; can tolerate morning direct sun but avoid harsh afternoon rays.
Sunlight Tolerance Tips:
Gradually acclimate to brighter light to prevent scorching; place in a spot with filtered light if outdoors, or near an east-facing window indoors.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
partial shade to full sun with protection from intense afternoon sun
Rotate plant weekly for even growth; use sheer curtains to filter intense light; avoid direct afternoon sun.
Watering
every 7–10 days during active growth, reducing to every 14–21 days in winter
Water thoroughly until it drains from the bottom, allow soil to dry between waterings, and avoid wetting foliage to prevent fungal issues.
Soil
well-draining, fertile, slightly acidic potting mix
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes; avoid compacted soil; top-dress with compost annually.
Temperature
Prefers 65–85°F (18–29°C); cooler temperatures (55–60°F or 13–15°C) at night promote better flowering.
Avoid sudden temperature changes; maintain consistent warmth; protect from cold drafts.
Fertilizing
every 4–6 weeks during growing season with balanced liquid fertilizer, none in winter
Flush soil occasionally to prevent salt buildup; switch to a phosphorus-rich fertilizer to encourage blooms.
Propagation
Methods
Stem cuttings with at least two nodes.
Step-by-Step Propagation Guide
- Take cutting, apply hormone, plant in medium, maintain humidity, wait for roots, pot separately.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–90%), warm temperatures (70–75°F or 21–24°C), and indirect light.
Medium
Well-draining mix of peat, perlite, and sand.
Hormone
Rooting hormone is recommended for faster and more reliable rooting.
Timeline
Roots develop in 3–6 weeks; new growth appears in 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, plastic wrap or propagator, misting bottle.
Quick Tips
Use healthy, non-flowering stems; keep soil consistently moist but not waterlogged; provide bottom heat if possible.
Pruning & Repotting
Pruning Guide
Method
Cut stems just above a leaf node or bud, remove crossing branches, and thin out dense growth.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove dead or overgrown stems.
Tools
Clean, sharp pruning shears or scissors, disinfectant.
Checklist
Disinfect tools, prune at the right time, make clean cuts, remove debris, reshape evenly.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Increase pot size by 2–3 inches in diameter; ensure good drainage holes.
Method
Remove plant gently, trim roots if necessary, place in a new pot with fresh soil, water lightly, and avoid direct sun for a few days.
Suggestions
Repot every 2–3 years or when roots fill the pot; necessary to refresh soil and provide space for growth.
Checklist
Choose right pot, prepare new soil, handle roots carefully, water after repotting, acclimate slowly.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water deeply, ensure drainage, avoid wetting leaves, adjust for season.
How to Apply Water Properly
Water directly at the root zone, ensuring even saturation to a depth of 6–8 inches, and allow excess water to drain completely to prevent waterlogging.
Watering Schedule Tips
Water deeply once the top inch of soil feels dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate compost for fertility; use a layer of gravel at the bottom of the pot.
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves, wilting, bud drop, or stunted growth indicate temperature stress.
Cold Stress
Low temperatures slow growth and can cause leaf drop or damage delicate tissues.
Solution: Move to a warmer location, protect from drafts, and cover with a frost cloth if temperatures drop below 50°F (10°C).
Hot Stress
Excessive heat can lead to leaf scorch, wilting, and reduced flowering.
Solution: Provide shade during peak heat, increase humidity, and ensure adequate watering.
Fertilizing Guide
Fertilizing Checklist
Check season, dilute fertilizer, apply to moist soil, avoid contact with roots, rinse between feedings.
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring to early fall); avoid fertilizing in winter.
