Care Details
Ideal Sunlight Coverage:
Partial shade to full shade; 3–4 hours of morning sun or dappled light is ideal; avoid intense afternoon sun.
Sunlight Tolerance Tips:
Acclimate gradually to brighter light; protect from harsh direct sun; place in a shaded area outdoors or filtered light indoors.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
partial shade to full shade
Avoid direct afternoon sun; provide dappled light; rotate plant for even growth
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly but infrequently; ensure good drainage; avoid wetting foliage.
Soil
moist, well-draining, humus-rich soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use organic matter, ensure good drainage, maintain slightly acidic pH
Temperature
Cool to moderate temperatures, ideally 50–70°F (10–21°C); prefers cooler conditions, especially during dormancy.
Protect from frost, avoid heat stress, maintain moderate temperatures
Fertilizing
every 4–6 weeks during spring and summer
Dilute fertilizer to prevent burn; fertilize during active growth; stop in winter.
Propagation
Methods
Stem cuttings or division; stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings, remove lower leaves, dip in rooting hormone, plant in medium, maintain humidity, and wait for roots.
Best Time: Early spring or late summer when the plant is actively growing.
Environment
High humidity, indirect light, and consistent warmth (65–75°F or 18–24°C).
Medium
Peat-based mix with perlite or sand for good drainage.
Hormone
Rooting hormone is recommended to improve success rates.
Timeline
Roots may develop in 3–6 weeks; establish in new pots within 1–2 months.
Tools Needed
Pruning shears, rooting hormone, small pots, humidity dome or plastic bag
Quick Tips
Use healthy cuttings, maintain humidity, provide indirect light, check for roots after 3 weeks
Pruning & Repotting
Pruning Guide
Method
Snip spent flowers and dead stems at the base; avoid cutting into healthy growth.
Pruning Plan
Remove spent flower stems and dead foliage to encourage reblooming and maintain plant health.
Tools
Clean bypass pruners or sharp scissors
Checklist
Remove dead flowers, cut back damaged stems, clean tools, dispose of debris
Repotting Guide
Best Season
Early spring before new growth begins.
Pot Size
One size up from the current pot; ensure good drainage holes.
Method
Gently remove the plant, trim any dead roots, place in a slightly larger pot with fresh soil, and water lightly.
Suggestions
Repot every 2–3 years or when the plant becomes root-bound; beneficial for maintaining vigor.
Checklist
Choose appropriate pot, prepare fresh soil, trim roots if needed, water lightly after repotting
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 without saturating the soil; water early in the day to allow foliage to dry.
Watering Schedule Tips
Water deeply once the top inch of soil is dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or sand for drainage; incorporate compost for fertility; ensure soil is loose and airy.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf scorch, stunted growth, or premature leaf drop in extreme heat; root rot or slow growth in excessive cold.
Cold Stress
Slows growth, may cause leaf discoloration, and increases susceptibility to root rot if soil remains wet.
Solution: Ensure well-drained soil, protect from frost, and provide a sheltered location in cold climates.
Hot Stress
Leaves may scorch, wilt, or drop; growth may become stunted due to heat stress.
Solution: Provide shade during peak heat, increase humidity, and water more frequently without overwatering.
Fertilizing Guide
Fertilizing Checklist
Use balanced fertilizer, dilute properly, fertilize monthly in growing season, cease in winter
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength; fertilize monthly during the growing season (spring to early summer) and avoid fertilizing in winter.
