Care Details
Ideal Sunlight Coverage:
Bright indirect light for 4–6 hours daily; tolerates partial shade, especially in warmer months.
Sunlight Tolerance Tips:
Acclimate gradually to direct sun to prevent scorching; protect from intense midday sun; adjust light exposure based on season.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
partial shade to full shade
Rotate plant for even growth; use sheer curtains for filtered light; avoid direct afternoon sun.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly but infrequently; ensure good drainage; avoid wetting foliage.
Soil
well-draining, rocky, slightly acidic soil
pH: Slightly acidic to neutral, pH 5.5–6.5.
Use a mix of peat, perlite, and sand; avoid heavy clay soils; ensure pots have drainage holes.
Temperature
Cool to moderate temperatures, ideally 50–65°F (10–18°C); prefers cooler conditions in winter.
Avoid sudden temperature changes; maintain consistent cool conditions; protect from frost.
Fertilizing
every 4–6 weeks during spring and summer
Dilute fertilizer to prevent burn; fertilize only during active growth; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings or division; stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Take a healthy cutting.
- Apply rooting hormone if used.
- Plant in medium.
- Maintain humidity.
- Wait for roots.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–80%), indirect light, and temperatures around 60–70°F (15–21°C).
Medium
Well-draining mix of peat, perlite, and sand; can also root in water initially.
Hormone
Optional but recommended for faster rooting.
Timeline
Roots typically form in 3–6 weeks; new growth may take an additional 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, humidity dome or plastic bag.
Quick Tips
Use healthy, non-flowering stems; maintain consistent moisture; provide bottom heat if possible.
Pruning & Repotting
Pruning Guide
Method
Pinch back stems or use clean cuts just above a leaf node.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove dead or weak stems.
Tools
Pruning shears, sterilizing solution, gloves.
Checklist
Sterilize tools; prune dead or weak stems; shape the plant; clean up debris.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Increase pot size by 1–2 inches in diameter; ensure good drainage holes.
Method
Remove plant gently; trim roots if necessary; repot in fresh, well-draining soil; water lightly.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for rejuvenation.
Checklist
Prepare new pot; trim roots if needed; use fresh soil; water sparingly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water thoroughly; ensure drainage; avoid leaf wetting.
How to Apply Water Properly
Water directly at the root zone until water drains from the bottom, ensuring even moisture without saturation. Water in the morning to allow foliage to dry.
Watering Schedule Tips
Water moderately during active growth (spring-summer), allowing soil to dry slightly between waterings. Reduce frequency in fall-winter to prevent root rot.
Soil Improvement
Add perlite or sand for drainage; incorporate organic matter for fertility; ensure aeration with coarse materials.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, or stunted growth in excessive heat; leaf drop or browning in cold stress.
Cold Stress
Slows growth, causes leaf discoloration, and may lead to root damage if temperatures drop below 40°F (4°C).
Solution: Protect from drafts; use a space heater in extreme cold; ensure adequate insulation if outdoors.
Hot Stress
Leaves may scorch, wilt, or drop; growth may cease in temperatures above 75°F (24°C) without adequate humidity.
Solution: Provide shade; increase humidity with misting or a pebble tray; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; fertilize during growing season; 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.
