Care Details
Ideal Sunlight Coverage:

Sunlight Tolerance Tips:
Acclimate gradually to intense sunlight; protect from harsh afternoon sun to prevent leaf scorch; adjust placement based on seasonal light changes.
Care Requirements
Care Difficulty
easymoderate
Sunlight
full sun to partial shade
Rotate plant for even light exposure; use shade cloth in extreme heat; monitor for sunburn signs.
Watering
every 7–10 days during active growth, less frequently in winter
Water thoroughly until it drains from the bottom; allow soil to dry between waterings; avoid overwatering.
Soil
well-draining, sandy or loamy soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use coarse sand or grit for drainage; avoid heavy clay soils; test pH periodically.
Temperature
Warm temperatures, ideally 70–85°F (21–29°C); tolerates mild frosts but prefers stable warmth.
Protect from frost; avoid drafts; maintain consistent warmth; adjust care for seasonal shifts.
Fertilizing
every 4–6 weeks during growing season, none in winter
Fertilize only when actively growing; avoid over-fertilizing to prevent salt buildup; flush soil occasionally.
Propagation
Methods
Stem cuttings; division of clumps.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Remove lower leaves.
- Apply rooting hormone.
- Plant in medium.
- Keep moist.
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 root in water initially.
Hormone
Optional but recommended for faster rooting.
Timeline
Roots develop in 3–6 weeks; new growth appears in 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining mix.
Quick Tips
Use healthy, non-flowering stems; keep cuttings out of direct sun; maintain humidity with a plastic bag.
Pruning & Repotting
Pruning Guide
Method
Selective cutting of stems; pinch back tips to encourage branching.
Pruning Plan
Remove dead or damaged growth; shape the plant to encourage bushiness; control size.
Tools
Pruning shears, gloves, disinfectant.
Checklist
Disinfect tools; prune in early spring; remove dead/damaged parts; shape evenly.
Repotting Guide
Best Season
Early spring before active growth begins.
Pot Size
One size larger pot; ensure good drainage holes.
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 fill the pot; beneficial for growth and soil refresh.
Checklist
Choose appropriate pot; prepare new soil mix; handle roots carefully; 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; water early in the day to minimize evaporation; ensure excess water drains 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 aeration.
Temperature Stress Management
Signs of Temperature Issues
Leaf drop, wilting, or browning edges in cold; scorching or yellowing in excessive heat.
Cold Stress
Slows growth, may cause leaf drop or damage; vulnerable to frost injury below 28°F (-2°C).
Solution: Move to a sheltered location; use frost cloth or mulch for protection; avoid sudden temperature drops.
Hot Stress
Leaves may wilt, curl, or scorch; growth may slow under prolonged high 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 foliage contact.
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); cease in fall/winter.
