Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours/day); tolerates partial shade in hot climates; adjust exposure based on seasonal light intensity.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight; protect from harsh midday sun in summer; place in brightest spot indoors if grown as a houseplant.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Rotate plant weekly for even growth; use sheer curtains to filter intense light; avoid sudden light changes.
Watering
every 7–10 days during active growth, reduce in winter
Water deeply but infrequently; ensure excellent drainage; avoid wetting foliage to prevent fungal issues.
Soil
well-draining, rocky or sandy soil with some organic matter
pH: 6.0–7.5 (slightly acidic to slightly alkaline).
Ensure pots have drainage holes; avoid heavy clay soils; top-dress with gravel for extra drainage.
Temperature
Prefers cool to moderate temperatures (60–70°F/15–21°C); tolerates cooler nights; avoid extreme heat.
Avoid placing near drafty windows; use shade cloth in summer; maintain consistent temperatures for best growth.
Fertilizing
every 4–6 weeks during growing season, none in winter
Apply fertilizer after watering to prevent root burn; stop feeding in late autumn; use a low-nitrogen formula for flowering plants.
Propagation
Methods
Stem cuttings or division; stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Take 3–4 inch cuttings.
- Remove lower leaves.
- Dip in rooting hormone.
- Plant in medium.
- Maintain humidity.
- Keep warm and bright.
Best Time: Late spring to early summer when the plant is actively growing.
Environment
Warm (65–75°F/18–24°C), high humidity (70–80%), and bright indirect light.
Medium
Well-draining mix of perlite and peat moss or cactus/succulent potting mix.
Hormone
Recommended to use rooting hormone for faster and more reliable rooting.
Timeline
Roots typically form in 3–6 weeks; new growth may appear in 2–3 months.
Tools Needed
Sharp pruners, rooting hormone, small pots, humidity dome or plastic bag, well-draining medium.
Quick Tips
Use healthy, non-flowering stems; keep soil consistently moist but not waterlogged; provide bottom heat if possible.
Pruning & Repotting
Pruning Guide
Method
Deadhead spent flowers; trim back leggy stems; shape the plant as needed with clean cuts.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and promote more blooms; remove spent flowers to extend flowering period.
Tools
Sharp, clean pruners or scissors, gloves.
Checklist
Use clean tools; prune dead or damaged stems; deadhead regularly; shape lightly as needed.
Repotting Guide
Best Season
Early spring before new growth begins.
Pot Size
Increase pot size by 1–2 inches in diameter; ensure good drainage holes.
Method
Gently remove plant; trim any dead roots; place in a slightly larger pot with fresh, well-draining soil; water lightly after repotting.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial to refresh soil and provide more space.
Checklist
Choose appropriate pot size; use fresh soil mix; handle roots gently; water sparingly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply at base; ensure drainage; avoid overhead watering.
How to Apply Water Properly
Water directly at the root zone until soil is moist but not waterlogged; ensure excess water drains freely; water early in the day to allow foliage to dry.
Watering Schedule Tips
Water sparingly, allowing soil to dry between waterings; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite, coarse sand, or pumice to improve drainage; incorporate organic matter like compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf scorch, stunted growth, or premature flowering in excessive heat; leaf drop or root rot in cold stress.
Cold Stress
Slows growth, may cause leaf discoloration, and increases susceptibility to root rot if soil remains cold and wet.
Solution: Move to a warmer location; insulate roots with mulch; avoid overwatering in cold conditions.
Hot Stress
Leaves may scorch, growth may stall, and flowering can be reduced in prolonged high temperatures.
Solution: Provide afternoon shade; increase humidity; water deeply but infrequently to keep roots cool.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; apply during growing season; avoid winter feeding; follow label instructions.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks during active growth; avoid fertilizing in winter.
