Care Details
Ideal Sunlight Coverage:

Sunlight Tolerance Tips:
Acclimate the plant gradually to direct sunlight to avoid scorching. Place in a spot with filtered light if outdoors, or near an east-facing window indoors.
Care Requirements
Care Difficulty
easymoderate
Sunlight
partial shade to full sun
Rotate plant weekly for even growth; avoid direct midday sun; adjust light exposure seasonally.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly until it drains from the bottom, avoid letting the plant sit in water, and adjust frequency based on season and weather.
Soil
well-drained, fertile, humus-rich soil
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 (15–21°C). Can tolerate cooler nights down to 50°F (10°C).
Keep away from drafty windows; maintain consistent room temperature; protect from extreme heat or cold.
Fertilizing
every 4–6 weeks during spring and summer
Fertilize only when actively growing; flush soil occasionally to prevent salt buildup; use a balanced formula.
Propagation
Methods
Stem cuttings in spring or early summer.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting, remove lower leaves, dip in rooting hormone (optional), 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 consistent warmth around 65–75°F (18–24°C).
Medium
Peat-based potting mix with perlite or sand for drainage.
Hormone
Optional, but rooting hormone can improve success rates.
Timeline
Roots typically form in 3–6 weeks; new growth may take 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, misting spray bottle.
Quick Tips
Use healthy, non-flowering stems; maintain humidity with a plastic cover; keep out of direct sun.
Pruning & Repotting
Pruning Guide
Method
Cut stems back to a healthy bud or lateral branch, avoid cutting into old wood.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove dead or weak stems.
Tools
Clean, sharp pruning shears or scissors.
Checklist
Disinfect tools, prune at the right time, remove dead/damaged growth, shape the plant.
Repotting Guide
Best Season
Early spring before active growth starts.
Pot Size
Choose a pot one size larger than the current one, with drainage holes.
Method
Gently remove the plant, trim any circling roots, place in a new pot with fresh soil, water lightly.
Suggestions
Repot every 2–3 years or when the plant becomes root-bound.
Checklist
Check root boundness, prepare new pot, trim roots if needed, use fresh soil, water lightly.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water thoroughly, ensure proper drainage, adjust for season.
How to Apply Water Properly
Water at the base of the plant, ensuring the root zone is moistened. Water deeply to encourage deep roots, and water in the morning to reduce evaporation and fungal risk.
Watering Schedule Tips
Water regularly during spring and summer, allowing the top inch of soil to dry out between waterings. Reduce frequency in fall and winter to prevent root rot.
Soil Improvement
Add perlite or coarse 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.
Cold Stress
Slows growth and can cause leaf drop or damage if exposed to prolonged cold below 50°F (10°C).
Solution: Move the plant to a warmer location, protect from drafts, and avoid sudden temperature drops.
Hot Stress
Leaves may scorch, wilt, or drop if exposed to excessive heat above 80°F (27°C) without adequate shade or water.
Solution: Provide shade, increase humidity, and water more frequently during hot spells.
Fertilizing Guide
Fertilizing Checklist
Check growth phase, dilute fertilizer, apply to moist soil, avoid winter feeding.
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during spring and summer. Avoid fertilizing in fall and winter.
