Care Requirements
Care Difficulty
easymoderate
Sunlight
full sun to partial shade
Rotate plant for even light; use sheer curtains in intense sun; avoid direct indoor light for prolonged periods.
Watering
every 7–10 days during active growth, reduce in winter
Water deeply but infrequently; avoid overwatering; ensure good drainage.
Soil
well-drained, sandy or loamy soil
pH: Slightly acidic to neutral (6.0–7.0).
Ensure pots have drainage holes; avoid heavy clay soils; test pH periodically.
Temperature
Prefers moderate temperatures (60–75°F/15–24°C); tolerates mild frosts but avoid prolonged cold.
Avoid sudden temperature changes; protect from drafts; maintain consistent room temperature indoors.
Fertilizing
every 2 months during growing season, none in winter
Apply fertilizer after watering; flush soil occasionally to prevent salt buildup; use organic options for gentle feeding.
Propagation
Methods
Stem cuttings or division.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Dip in hormone.
- Plant in medium.
- Keep moist.
Best Time: Spring or early summer when plant is actively growing.
Environment
Warm (70–75°F/21–24°C), high humidity, indirect light.
Medium
Well-draining potting mix with perlite or sand.
Hormone
Optional, but recommended for faster rooting.
Timeline
Roots in 3–6 weeks; establish in 2–3 months.
Tools Needed
Pruners, rooting hormone, small pots, misting spray bottle.
Quick Tips
Use healthy, non-flowering stems; maintain humidity with a plastic bag; avoid direct sun.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips for bushiness; cut just above a leaf node or bud.
Pruning Plan
Prune to maintain shape, encourage bushiness, and remove dead or weak growth.
Tools
Pruning shears, sharp scissors, disinfectant.
Checklist
Disinfect tools; prune during dormancy; remove dead or diseased parts.
Repotting Guide
Best Season
Spring, before new growth begins.
Pot Size
One size larger pot; ensure it’s not too big.
Method
Remove plant gently; trim roots if needed; use fresh soil; ensure drainage.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for growth.
Checklist
Check root bound status; use fresh soil mix; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water early in the day; ensure drainage.
How to Apply Water Properly
Water directly at the root zone until soil is moist but not waterlogged. Ensure excess water drains away to prevent standing moisture.
Watering Schedule Tips
Water sparingly, allowing soil to dry completely between waterings. Reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or sand for drainage; incorporate compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, stunted growth, or leaf drop.
Cold Stress
Slows growth, may cause leaf discoloration or dieback in prolonged cold.
Solution: Move to a warmer location; apply a layer of mulch for insulation; avoid overwatering.
Hot Stress
Leaves may scorch, wilt, or drop; growth may slow in extreme heat.
Solution: Provide partial shade during peak heat; increase watering cautiously; improve air circulation.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer label for NPK ratio; dilute correctly; apply during active growth.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks during growing season; avoid fertilizing in winter.
