Care Details
Ideal Sunlight Coverage:

Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight; protect from harsh midday sun in hot regions; adjust placement based on seasonal light changes.
Care Requirements
Care Difficulty
easyeasy
Sunlight
full sun to partial shade
Rotate plant for even growth; use shade cloth in extreme heat; avoid deep shade for prolonged periods.
Watering
every 7–10 days during active growth, less frequently in winter
Water thoroughly but infrequently; ensure soil dries between waterings; avoid overhead watering.
Soil
well-draining, sandy loam
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes; avoid heavy clay soils; amend with organic matter for better texture.
Temperature
Thrives in warm conditions; ideal range 60–80°F (15–27°C); tolerates mild frosts but prefers mild winters.
Avoid sudden temperature fluctuations; 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; use a balanced NPK ratio; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings or division; stem cuttings root easily in warm conditions.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Remove lower leaves.
- Dip in rooting hormone.
- Plant in moist medium.
- Keep warm and humid.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm, humid environment with indirect light; maintain consistent moisture.
Medium
Well-draining potting mix, such as a mix of perlite and peat moss.
Hormone
Optional but recommended for faster rooting.
Timeline
Roots develop in 2–4 weeks; new growth appears in 6–8 weeks.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining soil mix.
Quick Tips
Use clean tools to prevent disease; maintain high humidity for faster rooting; avoid direct sunlight.
Pruning & Repotting
Pruning Guide
Method
Use clean, sharp tools; cut just above a leaf node or bud; remove spent flowers to encourage reblooming.
Pruning Plan
Remove dead or overgrown stems to encourage bushier growth; prune after flowering to maintain shape.
Tools
Pruning shears, sterilized knife, gloves.
Checklist
Sterilize tools; prune dead or damaged stems; shape plant as desired; clean up debris.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Increase pot size by 1–2 inches in diameter; ensure good drainage.
Method
Remove plant gently; trim any circling roots; 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.
Checklist
Choose appropriate pot size; prepare new soil mix; 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; allow excess water to drain away; water early in the day to minimize evaporation.
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 coarse sand to improve drainage; incorporate compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, or stunted growth in extreme heat; leaf drop or browning in cold stress.
Cold Stress
Growth slows or halts; leaves may turn brown or black; susceptible to frost damage in prolonged cold.
Solution: Provide frost protection in winter; move potted plants indoors; use mulch to insulate roots.
Hot Stress
Leaves may scorch, wilt, or drop; growth may become leggy; flowering may be reduced.
Solution: Provide partial shade during peak heat; increase watering; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type; dilute properly; apply during active growth; avoid winter feeding.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength; fertilize every 4–6 weeks during growing season; avoid fertilizing in winter.
