Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours/day); adjust for intense summer sun with partial afternoon shade.
Sunlight Tolerance Tips:
Acclimate gradually to intense light; protect from scorching; move indoors in harsh conditions.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Rotate plant for even light; use sheer curtains in summer; avoid direct indoor light.
Watering
every 7–10 days during active growth, less frequently in winter
Water thoroughly until runoff, allow soil to dry between waterings, and avoid overhead watering.
Soil
well-draining, slightly alkaline soil with organic matter
pH: Slightly acidic to neutral (6.0–7.0).
Use raised beds for drainage; avoid heavy clay; amend with organic matter.
Temperature
60–85°F (15–29°C); prefers cooler winters (50–55°F/10–13°C) for dormancy.
Protect from frost; avoid sudden temperature swings; ensure good air flow.
Fertilizing
every 4–6 weeks during spring and summer, none in winter
Fertilize every 4–6 weeks during growth; avoid over-fertilizing; flush soil occasionally.
Propagation
Methods
Stem cuttings or air layering.
Step-by-Step Propagation Guide
- Select healthy stem, cut below node, apply hormone, plant in medium, maintain humidity.
Best Time: Spring or early summer when growth is active.
Environment
High humidity (70–80%), warm (70–75°F/21–24°C), indirect light.
Medium
Well-draining mix of peat, perlite, and sand.
Hormone
Rooting hormone recommended for faster rooting.
Timeline
4–8 weeks for roots; 6–12 months to establish.
Tools Needed
Pruners, rooting hormone, propagation tray, humidity dome.
Quick Tips
Use healthy, non-flowering stems; maintain consistent moisture; provide bottom heat if needed.
Pruning & Repotting
Pruning Guide
Method
Thinning cuts and heading back to maintain structure.
Pruning Plan
Shape plant, remove dead/diseased wood, and encourage airflow.
Tools
Pruning shears, loppers, gloves.
Checklist
Sterilize tools, prune dead/diseased wood, shape plant, clean up debris.
Repotting Guide
Best Season
Early spring before active growth begins.
Pot Size
One size larger pot (2–3 inches wider); ensure drainage holes.
Method
Use fresh well-draining soil, trim roots if needed, ensure proper drainage, water lightly after repotting.
Suggestions
Repot every 2–3 years or when roots fill the pot; essential for growth and health.
Checklist
Prepare new pot, remove plant gently, trim roots, add fresh soil, water lightly.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water deeply, ensure drainage, avoid wetting foliage.
How to Apply Water Properly
Water at the root zone, ensure even saturation to a depth of 6–8 inches, allow excess to drain, and water in the morning.
Watering Schedule Tips
Water deeply once the top inch of soil is dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or sand for drainage; incorporate compost for fertility; ensure good aeration.
Temperature Stress Management
Signs of Temperature Issues
Leaf drop, yellowing, stunted growth, or bud failure.
Cold Stress
Slows growth, causes leaf drop, and may lead to frost damage below 20°F (-6°C).
Solution: Move indoors or to a protected area; use frost cloth; ensure good air circulation.
Hot Stress
Wilting, leaf scorch, and reduced flowering in excessive heat above 90°F (32°C).
Solution: Provide shade, increase humidity, water deeply, and avoid midday watering.
Fertilizing Guide
Fertilizing Checklist
Use balanced fertilizer, follow dilution rates, fertilize during active growth, avoid winter.
Fertilizing Method
Balanced slow-release fertilizer (10-10-10) in spring/summer; reduce or stop in fall/winter.
