Care Details
Ideal Sunlight Coverage:

Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight to avoid scorching. For indoor placement, use a south-facing window with filtered light.
Care Requirements
Care Difficulty
easyeasy
Sunlight
full sun to partial shade
Rotate plants for even light exposure; use sheer curtains to diffuse harsh sunlight; monitor for signs of sunburn.
Watering
every 7–10 days during active growth, reduce in winter
Water deeply but infrequently; ensure good drainage; avoid waterlogging.
Soil
well-draining, sandy loam with moderate organic content
pH: Slightly acidic to neutral (6.0–7.0).
Ensure soil is not compacted; avoid heavy clay mixes; test pH periodically.
Temperature
Cool to moderate temperatures (15–20°C). Tolerates cooler conditions but avoids frost.
Avoid sudden temperature fluctuations; protect from drafts; maintain consistent humidity.
Fertilizing
every 4–6 weeks during growing season, none in winter
Apply fertilizer to moist soil to prevent root burn; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings or self-seeding.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Remove lower leaves.
- Dip in rooting hormone (optional).
- Plant in moist medium.
- Maintain humidity.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm (18–24°C), humid, and bright but indirect light.
Medium
Well-draining soil mix with perlite or sand.
Hormone
Optional, but can help speed up root development.
Timeline
Roots develop in 2–4 weeks; new growth appears in 6–8 weeks.
Tools Needed
Pruning shears, rooting hormone, small pots, misting spray bottle.
Quick Tips
Use healthy, non-flowering stems; keep soil consistently moist but not waterlogged; provide bottom heat if possible.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips or trim leggy stems to promote branching.
Pruning Plan
Light pruning to maintain shape and encourage bushier growth.
Tools
Clean, sharp pruning shears or scissors.
Checklist
Sterilize tools; prune during dormancy or after flowering; remove dead or damaged growth.
Repotting Guide
Best Season
Early spring before active growth begins.
Pot Size
One size up; ensure pot has drainage holes.
Method
Use fresh, well-draining soil; gently tease out compacted roots; place in a pot 1–2 inches larger in diameter.
Suggestions
Repot every 2–3 years or when roots outgrow the container.
Checklist
Prepare new pot with drainage; trim any circling roots; water lightly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water early morning or late evening; ensure proper drainage.
How to Apply Water Properly
Water at the base, ensuring moisture reaches the root zone without wetting foliage. Water until it drains from the bottom, then discard excess to prevent standing water.
Watering Schedule Tips
Water moderately during active growth (spring/summer), allowing soil to dry slightly between waterings. Reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, stunted growth, or premature flowering.
Cold Stress
Slows growth and can cause leaf damage or death if temperatures drop below 5°C.
Solution: Provide frost protection in cold climates; move potted plants indoors during freezes.
Hot Stress
Leaves may wilt, scorch, or drop; flowering may be reduced in excessive heat.
Solution: Provide shade during peak heat; increase watering frequency; improve air circulation.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; fertilize during growing season only; avoid contact with leaves.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks during active growth. Avoid fertilizing in winter.
