Care Details
Ideal Sunlight Coverage:

Sunlight Tolerance Tips:
Acclimate gradually to intense light; protect from direct midday sun to prevent scorching; adjust placement based on indoor/outdoor conditions.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Rotate plant for even light exposure; use sheer curtains to filter intense sunlight; avoid sudden light changes.
Watering
every 7–10 days, allowing soil to dry between waterings
Water thoroughly but infrequently; ensure soil dries between waterings; avoid overwatering.
Soil
well-draining, sandy loam with moderate organic content
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 60–75°F (15–24°C); tolerates cooler temperatures but avoids frost; thrives in moderate warmth.
Protect from frost; avoid sudden temperature swings; maintain moderate warmth for optimal growth.
Fertilizing
every 4–6 weeks during active growth with balanced liquid fertilizer
Fertilize during active growth; avoid over-fertilizing; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings in soil or water.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Remove lower leaves.
- Dip in rooting hormone (optional).
- Plant in medium.
- Maintain humidity.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm, humid environment with indirect light.
Medium
Well-draining potting mix or perlite and peat moss mixture.
Hormone
Optional but recommended for faster rooting.
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 for bushier growth; cut just above a leaf node or bud.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove dead or diseased parts.
Tools
Clean, sharp pruning shears or scissors.
Checklist
Sanitize tools; prune dead/damaged growth; shape plant; avoid over-pruning.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Increase pot size by 2–3 inches in diameter.
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 outgrow the pot; beneficial for growth and health.
Checklist
Check root bound status; prepare new pot; use fresh soil; 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 at the base of the plant, ensuring moisture reaches the root zone; allow excess water to drain away; water in the morning to reduce evaporation.
Watering Schedule Tips
Water deeply once 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 aeration with organic matter.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, or stunted growth in cold; scorching or leaf curl in excessive heat.
Cold Stress
Slows growth, may cause leaf discoloration, and increases susceptibility to disease in prolonged cold.
Solution: Move to a warmer location; provide a heat source if needed; avoid cold drafts.
Hot Stress
Leaves may wilt, scorch, or drop; growth may slow due to excessive heat.
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 contact with foliage.
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season; reduce or stop in winter.
