Care Details
Ideal Sunlight Coverage:
Bright indirect light for 4–6 hours; tolerates partial shade, especially in hot climates.
Sunlight Tolerance Tips:
Acclimate plants gradually to direct sun; protect from intense afternoon sun to prevent leaf scorch; adjust placement based on seasonal light changes.
Care Requirements
Care Difficulty
easymoderate
Sunlight
partial shade to full shade
Rotate plant for even growth; use sheer curtains to filter harsh light; move outdoors in spring/summer for brighter light.
Watering
every 7–10 days, allowing soil to dry slightly between waterings
Water thoroughly but allow soil to dry slightly between waterings; avoid overhead watering to prevent leaf diseases.
Soil
well-draining, loamy soil with organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use a mix of potting soil and perlite; avoid overwatering in heavy soils; test pH if leaf color dulls.
Temperature
Prefers 60–75°F (15–24°C); cooler temperatures enhance leaf color; tolerates mild frost.
Avoid sudden temperature shifts; protect from drafts; maintain moderate humidity.
Fertilizing
every 4–6 weeks during active growth with balanced liquid fertilizer
Apply fertilizer after watering to prevent root burn; flush soil occasionally to prevent salt buildup; stop fertilizing in fall.
Propagation
Methods
Stem cuttings or division; stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Take a 3–4 inch cutting, remove lower leaves, dip in rooting hormone, plant in medium, keep moist and humid.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–80%), indirect light, and consistent warmth (65–70°F).
Medium
Well-draining mix of peat, perlite, and sand; can also use a cactus mix.
Hormone
Rooting hormone is recommended to speed up root development.
Timeline
Roots develop in 3–6 weeks; new growth appears in 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, plastic wrap or propagator
Quick Tips
Use healthy, non-flowering stems; maintain humidity with a cover; keep out of direct sun.
Pruning & Repotting
Pruning Guide
Method
Snip flower stalks at the base; trim leggy stems just above a leaf node.
Pruning Plan
Remove spent flower stalks to encourage reblooming; trim leggy growth to maintain shape.
Tools
Clean bypass pruners or sharp scissors
Checklist
Sanitize tools, prune dead/leggy growth, remove spent flowers, shape as needed
Repotting Guide
Best Season
Early spring before new growth begins.
Pot Size
One size up from current pot; ensure good drainage holes.
Method
Gently remove plant, trim roots if needed, place in a slightly larger pot with fresh soil, water lightly.
Suggestions
Repot every 2–3 years or when roots fill the pot; helps refresh soil and prevent overcrowding.
Checklist
Choose appropriate pot, prepare fresh soil, handle roots carefully, water after repotting
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water deeply, ensure drainage, avoid wetting leaves
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone; water early in the day to minimize evaporation and fungal growth.
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 good aeration.
Temperature Stress Management
Signs of Temperature Issues
Leaf wilting, discoloration, or curling; stunted growth in extreme heat or cold.
Cold Stress
Slows growth and may cause leaf damage below 20°F (-7°C); roots are sensitive to freezing.
Solution: Mulch heavily in winter; protect from frost with a cover; move potted plants indoors if temperatures drop below freezing.
Hot Stress
Leaves may scorch or wilt in prolonged heat; growth may slow or stop.
Solution: Provide shade during peak heat; increase humidity with misting; ensure consistent watering.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer, apply during growing season, avoid winter feeding
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); avoid fertilizing in winter.
