Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; can tolerate partial shade, especially in hot climates.
Sunlight Tolerance Tips:
Acclimate gradually to intense sunlight; protect from harsh afternoon sun to avoid scorching; adjust placement based on indoor/outdoor conditions.
Care Requirements
Care Difficulty
easymoderate
Sunlight
full sun to partial shade
Rotate plant for even growth; use sheer curtains to filter intense light; avoid direct midday sun.
Watering
every 7–10 days, allowing soil to dry slightly between waterings
Water thoroughly but allow soil to dry between waterings; avoid overwatering, especially in winter.
Soil
well-draining, loamy soil with added 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 cool to moderate temperatures (60–70°F or 15–21°C); tolerates cooler conditions but avoid frost.
Avoid sudden temperature changes; keep away from heating/cooling vents; maintain consistent room temperature.
Fertilizing
every 4–6 weeks during active growth (spring and summer)
Dilute fertilizer to prevent burn; fertilize only when actively growing; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings or division; stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting, remove lower leaves, dip in hormone (optional), plant in medium, keep moist and humid.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–90%), indirect light, and warm temperatures (65–75°F or 18–24°C).
Medium
Well-draining mix like perlite and peat moss or cactus mix.
Hormone
Optional but recommended for faster rooting.
Timeline
Roots in 2–4 weeks; establish in 2–3 months.
Tools Needed
Pruners, rooting hormone, small pots, humidity dome or plastic bag.
Quick Tips
Use healthy, non-flowering stems; maintain humidity; avoid direct sun during rooting.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips or cut stems just above a leaf node; deadhead regularly.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove spent flowers for prolonged blooming.
Tools
Clean, sharp scissors or pruners.
Checklist
Sanitize tools, prune dead/leggy stems, deadhead spent flowers, shape as needed.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
One size up (e.g., from 4-inch to 6-inch pot); ensure good drainage.
Method
Use fresh well-draining soil, gently tease out roots, place in a slightly larger pot, water lightly after repotting.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for growth and soil freshness.
Checklist
Choose new pot, prepare soil, handle roots gently, water sparingly, place in appropriate light.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water thoroughly, ensure drainage, adjust for season.
How to Apply Water Properly
Water at the base of the plant, ensuring even moisture reaches the root zone; allow excess water to drain away to prevent waterlogging.
Watering Schedule Tips
Water when the top inch of soil feels 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
Wilting, yellowing leaves, or stunted growth in extreme heat or cold; bud drop in fluctuating temperatures.
Cold Stress
Slows growth and can cause leaf damage or death in temperatures below 50°F (10°C).
Solution: Protect from drafts and cold windows; move indoors in fall/winter; use a heat mat if needed.
Hot Stress
Leaves may wilt, scorch, or drop in temperatures above 80°F (27°C); growth may slow.
Solution: Provide shade during peak heat; increase humidity; water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Check growth phase, dilute fertilizer, apply to moist soil, avoid winter feeding.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); avoid fertilizing in winter.
