Care Details
Ideal Sunlight Coverage:
Partial shade to full sun (4–6 hours of direct sunlight or bright indirect light); prefers afternoon shade in hot climates.
Sunlight Tolerance Tips:
Acclimate gradually to direct sun to avoid leaf scorch; place in dappled light or filtered shade in intense summer sun; indoors, use a south-facing window with sheer curtains.
Care Requirements
Care Difficulty
easymoderate
Sunlight
partial shade to full sun
Rotate plant for even growth; provide shade during peak summer heat; avoid direct afternoon sun in hot regions.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly but infrequently; ensure soil dries slightly between waterings; avoid overwatering, especially in winter.
Soil
rich, moist, well-drained loam
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure good drainage; enrich with organic matter; avoid compacted soil.
Temperature
Cool to moderate temperatures (60–75°F or 15–24°C); tolerates cooler spring and fall conditions but avoids extreme heat.
Avoid sudden temperature changes; protect from frost; ensure good air circulation in hot weather.
Fertilizing
every 4–6 weeks during spring and summer
Apply fertilizer after watering to prevent root burn; stop feeding in late fall to allow dormancy; use a balanced NPK ratio.
Propagation
Methods
Seed propagation is most common; stem cuttings can also be used for vegetative propagation.
Step-by-Step Propagation Guide
- Seeds: sow in spring, keep moist.
- Cuttings: take 4–6 inch cuttings, remove lower leaves, plant in medium, maintain humidity.
Best Time: Early spring for seeds; late spring to early summer for stem cuttings.
Environment
Warm (65–75°F or 18–24°C), high humidity (70–80%), and bright indirect light for cuttings; cooler (50–60°F or 10–15°C) for seeds after germination.
Medium
Seed: well-draining soil mix; Cuttings: moist perlite or sand with some peat.
Hormone
Optional for cuttings, but rooting hormone can improve success rates.
Timeline
Seeds: germination in 2–4 weeks; Cuttings: roots in 3–6 weeks, establishment in 2–3 months.
Tools Needed
Pruners, rooting hormone (optional), pots, well-draining medium, humidity dome (optional).
Quick Tips
Use fresh seeds for best germination; mist cuttings regularly; avoid overwatering cuttings to prevent rot.
Pruning & Repotting
Pruning Guide
Method
Deadhead spent flowers; trim leggy stems to just above a leaf node; cut back old growth to encourage new shoots.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove spent flowers to promote reblooming.
Tools
Pruning shears, clean scissors, gloves.
Checklist
Sanitize tools; prune dead or damaged stems; remove spent flowers; shape as needed.
Repotting Guide
Best Season
Early spring before new growth begins.
Pot Size
One size larger pot (e.g., +2 inches in diameter); ensure good drainage.
Method
Remove plant gently, trim roots if crowded, place in a slightly larger pot with fresh soil, water thoroughly.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for container-grown plants to refresh soil and provide space.
Checklist
Check root bound status; prepare new pot with drainage; trim roots if needed; use fresh soil mix.
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; water until it drains from the bottom but avoid waterlogging; water in the morning to allow foliage to dry.
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; use mulch to retain moisture.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, stunted growth, or flower bud drop in extreme heat or cold.
Cold Stress
Slows growth, may cause leaf discoloration, and can lead to frost damage in freezing temperatures.
Solution: Protect from frost with a cover; move potted plants indoors; avoid placing near cold drafts or windows in winter.
Hot Stress
Leaves may scorch, wilt, or drop; growth may slow due to excessive heat and water loss.
Solution: Provide shade during peak heat; increase watering frequency; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Check season; dilute fertilizer; apply to moist soil; avoid contact with leaves.
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during the growing season (spring to early fall); avoid fertilizing in winter.
