Care Details
Ideal Sunlight Coverage:
Bright indirect light or partial shade; 4–6 hours of sunlight per day; adjust for intense summer sun.
Sunlight Tolerance Tips:
Acclimate gradually to direct sun to avoid scorching; protect from harsh afternoon sun; suitable for both indoor bright spots and outdoor partial shade.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
partial shade to full sun
Avoid direct midday sun; rotate plant for even growth; provide dappled light in summer.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly but infrequently; ensure proper drainage; adjust based on season and weather.
Soil
well-draining, loamy soil with some organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use a mix of potting soil and perlite, avoid heavy clay soils, ensure pots have drainage holes.
Temperature
Prefers moderate temperatures, 60–75°F (15–24°C); tolerates mild frosts but avoid prolonged cold.
Protect from frost, avoid sudden temperature swings, maintain moderate warmth year-round.
Fertilizing
every 4–6 weeks during spring and summer, none in winter
Fertilize lightly and frequently, flush soil occasionally to prevent salt buildup, stop in fall/winter.
Propagation
Methods
Stem cuttings or seed; stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Take cutting, apply hormone, plant in medium, maintain humidity, wait for roots.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–90%), warm temperatures (70–75°F), indirect light.
Medium
Well-draining mix of peat, perlite, and sand or cactus mix.
Hormone
Rooting hormone is recommended to improve success rates.
Timeline
Roots may develop in 4–8 weeks; establish in new pot after 3–6 months.
Tools Needed
Pruning shears, rooting hormone, pots, misting spray bottle.
Quick Tips
Use healthy, non-flowering stems, keep consistently moist, provide bottom heat if possible.
Pruning & Repotting
Pruning Guide
Method
Thinning cuts to open up the plant, heading back to encourage branching.
Pruning Plan
Shape the plant, remove dead/diseased growth, encourage bushier growth.
Tools
Pruning shears, loppers (for larger branches), sterilizing solution.
Checklist
Sterilize tools, prune dead/diseased wood, shape as desired, clean up debris.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Increase pot size by 2–3 inches in diameter; ensure good drainage.
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 health.
Checklist
Check root bound status, prepare new pot, trim roots, add fresh soil, water lightly.
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; avoid wetting foliage; allow excess water to drain away.
Watering Schedule Tips
Water deeply once the top inch of soil feels 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, yellowing, stunted growth, or browning leaf edges.
Cold Stress
Slows growth, may cause leaf drop or dieback in severe cases.
Solution: Move to a warmer location, protect from drafts, use frost cloth if outdoors in cold weather.
Hot Stress
Wilting, leaf scorch, or reduced flowering due to excessive heat.
Solution: Provide shade, increase humidity, water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Check season, use diluted fertilizer, apply to moist soil, avoid contact with roots.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); avoid fertilizing in winter.
