Care Details
Ideal Sunlight Coverage:
Full sun to partial shade (4–6 hours of direct sunlight daily). Tolerates light shade, especially in hot climates.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight to prevent scorching. In hot regions, provide afternoon shade. Indoors, place near a south-facing window with filtered light.
Care Requirements
Care Difficulty
easymoderate
Sunlight
full sun to partial shade
Rotate plant for even growth; use sheer curtains to diffuse intense light; monitor for leaf burn.
Watering
every 7–10 days during growing season, reduce in winter
Water thoroughly until runoff, allow soil to dry partially between waterings, and avoid overhead watering to prevent fungal issues.
Soil
well-drained, fertile loam
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure soil is not waterlogged; amend heavy clay soils with organic matter; test pH periodically.
Temperature
Prefers cool to moderate temperatures (60–75°F or 15–24°C). Tolerates cooler nights and can withstand light frosts.
Protect from frost; avoid placing near heat sources; maintain consistent temperatures for best growth.
Fertilizing
every 4–6 weeks during active growth
Apply fertilizer to moist soil to prevent root burn; avoid over-fertilizing, which can harm the plant; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings or division of clumps in spring or early summer.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings with at least two nodes.
- Remove lower leaves.
- Dip in rooting hormone (optional).
- Plant in moist medium.
- Keep humid and warm.
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 with perlite or sand for cuttings; moist, rich soil for division.
Hormone
Optional, but rooting hormone can improve success rates for stem cuttings.
Timeline
Stem cuttings may root in 3–6 weeks; division establishes quickly within a growing season.
Tools Needed
Pruning shears, rooting hormone, small pots, misting spray bottle.
Quick Tips
Keep cuttings out of direct sun; maintain high humidity with a plastic cover; check for roots after 3 weeks.
Pruning & Repotting
Pruning Guide
Method
Deadhead spent flowers; cut back leggy stems to encourage branching; remove any dead or damaged growth.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove spent flowers to promote reblooming.
Tools
Pruning shears, clean scissors, gloves.
Checklist
Sterilize tools; prune after flowering; remove dead/damaged growth; shape as desired.
Repotting Guide
Best Season
Early spring before new growth begins.
Pot Size
One size larger pot (e.g., +2 inches in diameter).
Method
Remove plant gently; trim any circling roots; place in a slightly larger pot with fresh, well-draining soil; water thoroughly.
Suggestions
Repot every 2–3 years or when roots fill the container to prevent overcrowding.
Checklist
Choose appropriate pot size; use fresh soil mix; handle roots carefully; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; ensure drainage; avoid wetting foliage.
How to Apply Water Properly
Water directly at the root zone, ensuring even saturation to a depth of 6–8 inches. Ensure excess water drains freely to prevent root rot. Water in the morning to allow foliage to dry.
Watering Schedule Tips
Water deeply once a week during active growth, reducing frequency in winter to every 2–3 weeks. Adjust based on rainfall and soil moisture retention.
Soil Improvement
Add compost or well-rotted manure to enhance fertility and structure; mix in perlite or sand for better drainage.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, stunted growth, or leaf drop in extreme heat or cold.
Cold Stress
Low temperatures slow growth and may cause leaf discoloration or dieback, especially if prolonged below freezing.
Solution: Mulch heavily around the base in winter; move potted plants to sheltered locations; avoid overwatering in cold conditions.
Hot Stress
Excessive heat can lead to wilting, leaf scorch, and reduced flowering, especially in direct sun without adequate water.
Solution: Provide shade during peak heat; increase watering frequency; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; fertilize during active growth; avoid winter feeding.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks during spring and summer. Reduce or stop fertilizing in fall and winter.
