Care Details
Ideal Sunlight Coverage:
Full sun to partial shade; 6–8 hours of direct sunlight per day, with some afternoon shade in hot climates.
Sunlight Tolerance Tips:
Acclimate plants gradually to full sun if moved from shade; protect from intense midday sun to prevent scorching; adjust placement based on seasonal light intensity.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Monitor for leaf scorch, provide shade during peak heat, rotate plants for even light exposure
Watering
every 7–10 days during growing season, reduce in winter
Water thoroughly but infrequently; ensure good drainage; avoid wetting foliage.
Soil
well-drained, loamy soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Test soil pH, amend with compost, ensure good drainage, avoid compacted soil
Temperature
Prefers warm to hot conditions; ideal range 70–85°F (21–29°C); tolerates heat well but may struggle below 50°F (10°C).
Adjust watering in extreme heat, protect from frost, ensure good air circulation
Fertilizing
every 4–6 weeks during active growth
Fertilize in early morning or evening, stop during dormancy, flush soil occasionally to prevent salt buildup
Propagation
Methods
Stem cuttings or division; stem cuttings are the most common method for home growers.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting, remove lower leaves, dip in rooting hormone (optional), plant in moist medium, keep humid and warm.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm, humid environment with indirect light; maintain temperatures around 70–75°F (21–24°C).
Medium
Well-draining potting mix, such as a mix of peat, perlite, and sand.
Hormone
Rooting hormone is optional but recommended for faster root development.
Timeline
Roots typically develop in 3–6 weeks; new growth may appear in 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, misting spray bottle
Quick Tips
Use healthy, non-flowering stems, maintain high humidity, avoid direct sunlight
Pruning & Repotting
Pruning Guide
Method
Use clean, sharp tools; make cuts just above a leaf node or branch junction.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove dead or diseased parts.
Tools
Pruning shears, sterilizing solution, gloves
Checklist
Sterilize tools, prune dead/damaged parts, shape the plant, clean up debris
Repotting Guide
Best Season
Early spring before active growth begins.
Pot Size
Increase pot size by 1–2 inches in diameter; avoid oversized pots.
Method
Remove the plant gently, trim any circling roots, place in a slightly larger pot with fresh soil, water lightly.
Suggestions
Repot every 2–3 years or when the plant becomes root-bound; beneficial for maintaining vigor.
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 deeply, ensure drainage, avoid foliage wetting
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone; allow excess water to drain away; water in the morning to reduce evaporation.
Watering Schedule Tips
Water deeply once the top inch of soil feels dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add compost or well-rotted manure for fertility; mix in perlite or sand for drainage; ensure aeration with organic matter.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis or wilting in excessive heat; stunted growth or leaf drop in cold stress.
Cold Stress
Low temperatures slow growth and can cause root damage or dieback; prolonged cold may lead to plant death.
Solution: Protect with mulch in winter; move potted plants indoors or to a sheltered location; avoid overwatering in cold conditions.
Hot Stress
Excessive heat can cause leaf scorch, wilting, or reduced flowering; may lead to dehydration if water needs are not met.
Solution: Provide afternoon shade; increase watering frequency; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type, dilute properly, apply during growing season, avoid winter feeding
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength; apply every 4–6 weeks during the growing season (spring to early fall); avoid fertilizing in winter.
