Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Rotate plant for even light exposure; use sheer curtains to filter intense sun; avoid sudden light changes.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly until runoff, ensure good drainage, and avoid waterlogging roots.
Soil
well-drained, loamy soil with some organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0)
Use a mix of potting soil and perlite; avoid heavy clay soils; ensure pots have drainage holes.
Temperature
Prefers warm temperatures, 60–75°F (15–24°C); tolerates mild frosts but thrives in mild climates.
Monitor temperature changes; protect from drafts; adjust care based on seasonal shifts.
Fertilizing
every 4–6 weeks during spring and summer
Dilute fertilizer to half strength; apply after watering; stop in fall to prepare for dormancy.
Propagation
Methods
Stem cuttings
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Dip in rooting hormone.
- Plant in medium.
- Keep moist and humid.
Best Time: Spring or early summer when plant is actively growing
Environment
High humidity, indirect light, and warm temperatures (70–75°F or 21–24°C)
Medium
Peat-based mix with perlite or sand for good drainage
Hormone
Recommended to promote root development
Timeline
Roots in 3–6 weeks; establish in 2–3 months
Tools Needed
Pruning shears, rooting hormone, small pots, misting spray bottle
Quick Tips
Use healthy, non-flowering stems; maintain humidity with a plastic bag; keep out of direct sun.
Pruning & Repotting
Pruning Guide
Method
Cut stems just above a leaf node or bud; remove crossing or crowded branches
Pruning Plan
Encourage bushy growth and flowering; remove dead or weak stems to improve air circulation.
Tools
Pruning shears, loppers (for larger stems), gloves
Checklist
Sterilize tools; prune at the right time; make clean cuts; dispose of pruned material.
Repotting Guide
Best Season
Early spring before active growth starts
Pot Size
One size larger pot; ensure good drainage holes
Method
Remove plant gently; trim roots if needed; place in new pot with fresh soil; water lightly
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for growth and health.
Checklist
Check root bound status; prepare new pot; use fresh soil mix; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water deeply; ensure drainage; adjust for season.
How to Apply Water Properly
Water directly at the root zone, apply until water drains from the bottom, and water in the morning to reduce evaporation.
Watering Schedule Tips
Water deeply once a week during active growth; reduce frequency in winter to every 2–3 weeks, allowing soil to dry between waterings.
Soil Improvement
Add perlite or sand for drainage; incorporate compost for fertility; ensure aeration with organic matter.
Temperature Stress Management
Signs of Temperature Issues
Leaf drop, wilting, or stunted growth in cold; scorching or leaf burn in excessive heat.
Cold Stress
Slows growth, may cause leaf drop, and can lead to dieback in prolonged cold.
Solution: Protect from frost with a cover; move indoors in freezing conditions; ensure good air circulation to prevent mold.
Hot Stress
Leaves may scorch, wilt, or drop; growth may slow due to excessive heat.
Solution: Provide shade during peak heat; increase watering; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Check season; dilute properly; apply to moist soil; avoid contact with leaves.
Fertilizing Method
Use balanced liquid fertilizer every 4–6 weeks during growing season (spring/summer); avoid fertilizing in winter.
