Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily); tolerates partial shade in hot climates.
Sunlight Tolerance Tips:
Acclimate plants gradually to direct sun to prevent scorching; provide afternoon shade in extreme heat; adjust indoor placement to mimic natural light 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 sudden light changes.
Watering
every 7–10 days during growing season, reduce in winter
Water thoroughly but infrequently; ensure soil dries between waterings; avoid overwatering.
Soil
well-draining, loamy soil with moderate organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use raised beds for better drainage; avoid compacted soil; amend with organic matter annually.
Temperature
Warm temperatures (65–85°F or 18–29°C); prefers stable conditions; sensitive to frost.
Protect from frost; avoid sudden temperature swings; maintain consistent warmth.
Fertilizing
every 4–6 weeks during active growth
Apply fertilizer after watering to prevent root burn; flush soil occasionally to prevent salt buildup; reduce feeding in dormancy.
Propagation
Methods
Stem cuttings or seeds; stem cuttings are faster and more reliable.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Remove lower leaves.
- Apply rooting hormone.
- Plant in medium.
- Keep moist and warm.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm, humid conditions with indirect light; maintain consistent moisture.
Medium
Well-draining potting mix with perlite or sand; can also root in water.
Hormone
Rooting hormone is recommended to speed up root development.
Timeline
Roots develop in 2–4 weeks; new growth appears in 6–8 weeks.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining medium.
Quick Tips
Use healthy, non-flowering stems; keep cuttings out of direct sun; maintain humidity with a plastic bag.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips for bushier growth; cut back leggy stems to encourage branching.
Pruning Plan
Prune to maintain shape, encourage bushiness, and remove dead or diseased growth.
Tools
Pruning shears, sterilizing solution, gloves.
Checklist
Sterilize tools; prune during dormancy; remove dead/diseased parts; shape as desired.
Repotting Guide
Best Season
Spring, before the growing season begins.
Pot Size
One size larger pot (e.g., +2 inches in diameter); ensure good drainage.
Method
Remove plant gently; trim roots if crowded; place in a slightly larger 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 with drainage; trim roots if needed; use fresh soil.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water deeply; ensure drainage; avoid wetting leaves.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone; water early in the day to minimize evaporation; allow excess water to drain away.
Watering Schedule Tips
Water deeply once the top inch of soil is 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, leaf drop, or chlorosis in cold; scorching or stunted growth in excessive heat.
Cold Stress
Growth slows or halts; leaves may turn yellow or brown; risk of frost damage.
Solution: Move to a warmer location; provide frost protection; avoid cold drafts.
Hot Stress
Leaf scorch, wilting, or reduced flowering; soil dries out quickly.
Solution: Provide shade during peak heat; increase watering frequency; use mulch to retain moisture.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type; dilute properly; apply during active growth; avoid winter feeding.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season; avoid fertilizing in winter.
