Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours/day); tolerates partial shade but may become leggy.
Sunlight Tolerance Tips:
Acclimate gradually to intense sunlight; protect from harsh afternoon sun in summer; place in brightest spot indoors.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun
Rotate plant weekly; use sheer curtains in summer; avoid north-facing windows indoors.
Watering
every 2–3 weeks during active growth, less in winter
Water thoroughly until it drains from the bottom, ensure soil dries between waterings, and avoid overhead watering to prevent fungal issues.
Soil
well-drained, sandy or loamy soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use gritty mix; avoid heavy clay soils; topdress with mulch to retain moisture.
Temperature
Prefers 65–85°F (18–29°C); tolerates mild frost but thrives in warm conditions.
Avoid drafts; protect from frost; maintain consistent warmth during active growth.
Fertilizing
every 3 months with slow-release fertilizer during active growth
Fertilize only when actively growing; flush soil occasionally to prevent salt buildup; use a low-nitrogen formula.
Propagation
Methods
Stem cuttings or seed; stem cuttings are more reliable for home growers.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Remove lower leaves.
- Dip in rooting hormone.
- Plant in medium.
- Keep moist and warm.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm (70–75°F), high humidity (70–80%), and bright indirect light.
Medium
Well-draining mix of perlite and peat moss or cactus/succulent soil.
Hormone
Recommended to use rooting hormone for faster and more reliable rooting.
Timeline
Roots may appear in 4–8 weeks; establish in new pot after 3–6 months.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining medium.
Quick Tips
Use fresh cuttings; maintain humidity with a plastic bag; avoid direct sun during rooting.
Pruning & Repotting
Pruning Guide
Method
Selective thinning and heading back to shape the plant and improve air circulation.
Pruning Plan
Prune to maintain shape, encourage bushiness, and remove dead or overgrown branches.
Tools
Pruning shears, loppers (for larger branches), gloves.
Checklist
Sterilize tools; prune dead/damaged branches first; make clean cuts just above buds.
Repotting Guide
Best Season
Early spring before active growth starts.
Pot Size
Move to a pot 1–2 inches larger in diameter; avoid overpotting.
Method
Remove plant gently; trim roots if necessary; use fresh, well-draining soil; ensure drainage holes are clear.
Suggestions
Repot every 2–3 years or when roots fill the pot; may become root-bound and thrive in crowded conditions.
Checklist
Check root boundness; prepare new pot with drainage; use fresh soil mix; water lightly 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 root zone, apply slowly to allow deep penetration, ensure excess water drains away, and water in the morning to reduce evaporation.
Watering Schedule Tips
Water deeply but infrequently, allowing soil to dry out between waterings. Reduce watering in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand to improve drainage; incorporate compost for fertility; ensure pots have drainage holes.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis, leaf drop, or stunted growth in extreme cold; wilting or scorching in excessive heat.
Cold Stress
Slows growth, may cause leaf drop, and increases susceptibility to root rot.
Solution: Move to a warmer location; insulate roots with mulch; reduce watering in cold periods.
Hot Stress
Leaves may scorch, growth may slow, and water demand increases.
Solution: Provide partial shade during peak heat; increase watering frequency; mist foliage in extreme heat.
Fertilizing Guide
Fertilizing Checklist
Check growth phase; dilute fertilizer; apply to moist soil; avoid winter feeding.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); avoid fertilizing in winter.
