Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily); tolerates partial shade but may become leggy.
Sunlight Tolerance Tips:
Acclimate gradually if moving from shade to sun; protect from intense midday sun in summer; ensure good air circulation to prevent fungal issues.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Rotate plant for even growth; use sheer curtains to filter intense light; avoid placing near reflective surfaces that intensify sunlight.
Watering
every 7–10 days during active growth, less frequently in winter
Water thoroughly until runoff, allow soil to dry between waterings, avoid overhead watering to prevent fungal issues.
Soil
well-draining, loamy soil with some organic matter
pH: 5.5–6.5 (slightly acidic).
Ensure pots have drainage holes; avoid heavy clay soils; test soil pH annually.
Temperature
Prefers 60–75°F (15–24°C); tolerates mild frosts but thrives in temperate climates.
Protect from sudden temperature drops; avoid placing near drafty windows or heat vents; maintain consistent temperatures for optimal growth.
Fertilizing
every 2–3 months during spring and summer with balanced slow-release fertilizer
Apply fertilizer before watering to prevent root burn; use a fertilizer with higher nitrogen content for leafy growth; flush soil occasionally to prevent salt buildup.
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, apply rooting hormone, plant in medium, maintain humidity, keep warm and bright.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–90%), warm temperatures (65–75°F), indirect light.
Medium
Well-draining mix of perlite and peat moss or cactus potting mix.
Hormone
Recommended to use rooting hormone for faster and more reliable rooting.
Timeline
Roots typically form in 4–8 weeks; new growth may take 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, plastic bags or propagator, misting bottle.
Quick Tips
Use healthy, non-flowering stems; keep soil consistently moist but not waterlogged; provide bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Use clean cuts just above a leaf node or branch junction; avoid leaving stubs.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove dead or diseased wood.
Tools
Pruning shears, loppers, disinfectant (e.g., rubbing alcohol), gloves.
Checklist
Disinfect tools, prune dead/diseased wood first, make clean cuts, remove crossing branches, clean up debris afterward.
Repotting Guide
Best Season
Early spring before the active growing season begins.
Pot Size
Increase pot size by 2–3 inches in diameter; ensure good drainage holes.
Method
Remove plant gently, trim any circling roots, place in a new pot with fresh soil, water thoroughly, avoid fertilizing for a month.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for younger plants to encourage growth.
Checklist
Choose appropriate pot, prepare new soil mix, inspect roots, position plant correctly, water well, place in appropriate light.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water deeply, ensure drainage, adjust for season.
How to Apply Water Properly
Water directly at the root zone, ensuring even saturation to a depth of 6–8 inches, allow excess water to drain freely, water early in the morning to minimize evaporation.
Watering Schedule Tips
Water deeply once the top 1–2 inches of soil are dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate compost for fertility; use pine bark or peat moss to lower pH if needed.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis (yellowing leaves), leaf drop, stunted growth, or browning leaf edges.
Cold Stress
Leaves may curl, turn brown, or drop; growth slows or halts; risk of root damage in freezing conditions.
Solution: Move to a sheltered location or indoors during frosts; use frost cloth for outdoor protection; ensure well-draining soil to prevent cold waterlogging.
Hot Stress
Wilting, leaf scorch (brown/burnt edges), reduced growth, or premature leaf drop.
Solution: Provide shade during peak heat, increase watering frequency, use mulch to retain soil moisture, ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type, dilute correctly, apply during growing season, avoid winter feeding.
Fertilizing Method
Use a balanced, slow-release fertilizer in spring; dilute liquid fertilizer to half-strength monthly during growing season; avoid fertilizing in winter.
