Care Requirements
Care Difficulty
easymoderate
Sunlight
partial shade to full sun, with protection from intense midday sun
Rotate plant for even growth; use sheer curtains to filter intense light; provide shade during peak sun hours.
Watering
every 5–7 days, allowing soil to dry slightly between waterings
Keep soil consistently moist but not waterlogged; avoid letting roots sit in water; adjust based on season and growth stage.
Soil
well-draining, fertile potting mix with added organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use a mix with good drainage, avoid heavy clay soils, ensure pH is within optimal range.
Temperature
Prefers 60–75°F (15–24°C); cooler temperatures at night; avoid exposure to frost or extreme heat.
Protect from frost, avoid sudden temperature changes, maintain moderate warmth.
Fertilizing
every 2 weeks during active growth with balanced liquid fertilizer, reducing frequency in winter
Fertilize after watering to prevent root burn; flush soil occasionally to prevent salt buildup; avoid over-fertilizing.
Propagation
Methods
Stem cuttings
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting, remove lower leaves, apply rooting hormone, plant in medium, keep moist and humid.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity, indirect light, and warm temperatures (65–75°F).
Medium
Well-draining potting mix with perlite or sand
Hormone
Rooting hormone is recommended for faster root development.
Timeline
Roots develop in 2–4 weeks; new growth appears in 6–8 weeks.
Tools Needed
Pruning shears, rooting hormone, small pots, misting spray bottle.
Quick Tips
Use healthy, non-flowering stems; maintain consistent moisture; provide bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips, remove leggy stems, deadhead spent flowers.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove spent flowers to promote continuous blooming.
Tools
Clean pruning shears, gloves.
Checklist
Sanitize tools, prune during active growth, remove dead/damaged parts, shape as desired.
Repotting Guide
Best Season
Spring, before new growth begins.
Pot Size
One size up from current pot; ensure good drainage.
Method
Use fresh well-draining soil, gently tease out roots, place in slightly larger pot, water thoroughly.
Suggestions
Repot every 1–2 years or when roots outgrow the pot; beneficial for growth and blooming.
Checklist
Choose appropriate pot, prepare new soil, handle roots carefully, water after repotting, place in suitable light.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water thoroughly, ensure drainage, adjust for season, avoid wetting foliage.
How to Apply Water Properly
Water thoroughly at the root zone until it drains from the bottom; ensure even moisture distribution; water in the morning to reduce evaporation.
Watering Schedule Tips
Water when the top inch of soil feels dry; increase frequency in hot, dry conditions; reduce in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate organic matter for fertility; ensure proper aeration.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, stunted growth, or yellowing leaves.
Cold Stress
Slows growth, may cause leaf discoloration, and increases susceptibility to disease.
Solution: Move to a warmer location, insulate pots, and avoid cold drafts.
Hot Stress
Leaves may wilt, scorch, or drop; growth may slow or stop.
Solution: Provide shade, increase humidity, and water more frequently during heatwaves.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer, apply during growing season, flush periodically, avoid contact with stems.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season; reduce or stop in winter.
