Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; avoid direct sunlight which can scorch leaves.
Sunlight Tolerance Tips:
Acclimate gradually to new light conditions; place in east or north-facing windows indoors; use sheer curtains to filter intense light.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
bright, indirect light
Rotate plant weekly for even growth; adjust light exposure seasonally.
Watering
every 7–10 days, allowing soil to dry slightly between waterings
Water thoroughly but allow soil to dry between waterings; avoid wetting leaves to prevent fungal issues.
Soil
well-draining, peat-based potting mix
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes; avoid compacted soil.
Temperature
Ideal range 60–75°F (15–24°C); prefers cooler temperatures at night.
Avoid sudden temperature changes; maintain consistent indoor temperatures.
Fertilizing
every 2 weeks during active growth (spring and summer), every 3 months with slow-release fertilizer
Fertilize after watering to prevent root burn; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings or leaf cuttings.
Step-by-Step Propagation Guide
- Select healthy leaf or stem.
- Cut below node.
- Apply hormone (optional).
- Plant in medium.
- Maintain humidity.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–90%), warm temperatures (70–75°F), and indirect light.
Medium
Peat-based mix with perlite or sand for good drainage.
Hormone
Rooting hormone can be used but is not strictly necessary.
Timeline
Roots develop in 4–8 weeks; new growth appears in 2–3 months.
Tools Needed
Sharp scissors, rooting hormone, propagation tray, humidity dome.
Quick Tips
Use healthy, disease-free cuttings; maintain consistent moisture.
Pruning & Repotting
Pruning Guide
Method
Snip stems just above a leaf node or junction; remove entire leaves if heavily damaged.
Pruning Plan
Remove spent flowers and yellowing leaves to encourage new growth and maintain appearance.
Tools
Clean, sharp scissors or pruning shears.
Checklist
Sanitize tools; prune dead/damaged parts; avoid over-pruning.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
One size larger pot (e.g., +2–3 cm in diameter).
Method
Gently remove plant; trim roots if necessary; place in new pot with fresh soil; water lightly.
Suggestions
Repot every 1–2 years or when roots fill the pot; use fresh potting mix to refresh nutrients.
Checklist
Check root health; use fresh soil; ensure proper drainage; water lightly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water thoroughly; ensure drainage; discard excess water.
How to Apply Water Properly
Water directly at the root zone until water drains from the bottom; ensure excess water is removed to prevent waterlogging.
Watering Schedule Tips
Water when the top inch of soil is dry; reduce frequency in winter to prevent root rot. Adjust based on humidity and temperature.
Soil Improvement
Add perlite or coarse sand to improve drainage; incorporate organic matter for fertility.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, or stunted growth in extreme heat or cold.
Cold Stress
Slows growth, causes leaf discoloration, and may lead to root damage.
Solution: Move to a warmer location; insulate pots; avoid cold drafts.
Hot Stress
Leaves may wilt, curl, or develop brown edges; flowers may drop prematurely.
Solution: Provide shade; increase humidity; water more frequently but avoid overwatering.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer strength; apply after watering; follow seasonal schedule.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); reduce or stop in fall/winter.
