Care Details
Ideal Sunlight Coverage:
Full sun to partial shade (4–6 hours of direct sunlight daily); tolerates light shade in hot climates.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight; protect from harsh afternoon sun in summer; adjust placement based on seasonal light intensity.
Care Requirements
Care Difficulty
easyeasy
Sunlight
full sun to partial shade
Morning sun is ideal; provide shade during peak heat; rotate pots for even growth.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly but infrequently; ensure good drainage; avoid wetting foliage.
Soil
well-draining, sandy loam with moderate organic content
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure good drainage; avoid heavy clay soils; enrich with organic matter if needed.
Temperature
Prefers cool to moderate temperatures (60–75°F or 15–24°C); thrives in cooler spring and fall conditions.
Avoid sudden temperature changes; protect from frost; ensure good air circulation in heat.
Fertilizing
every 4–6 weeks during spring and summer
Fertilize sparingly to prevent leggy growth; stop feeding in late summer to prepare for dormancy.
Propagation
Methods
Stem cuttings or self-seeding; easily propagated from soft stem cuttings taken in spring or early summer.
Step-by-Step Propagation Guide
- Take 3–4 inch cuttings.
- 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 (65–75°F or 18–24°C), humid environment with bright, indirect light.
Medium
Well-draining potting mix (e.g., peat-based mix with perlite or sand).
Hormone
Optional, but rooting hormone can speed up root development.
Timeline
Roots typically form in 2–4 weeks; plants can be transplanted after 6–8 weeks.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining soil mix.
Quick Tips
Use clean tools to prevent disease; maintain consistent moisture; provide bottom heat if possible.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips or cut stems just above a leaf node; deadhead spent flowers regularly.
Pruning Plan
Light pruning to maintain shape and encourage bushier growth; remove spent flowers to promote reblooming.
Tools
Clean pruning shears or scissors.
Checklist
Use clean tools; prune after flowering; remove dead or damaged stems.
Repotting Guide
Best Season
Early spring before active growth begins.
Pot Size
One size larger pot (e.g., 2 inches wider in diameter).
Method
Gently remove the plant; trim any circling roots; repot in fresh, well-draining soil with a slightly larger pot.
Suggestions
Repot every 1–2 years or when the plant becomes root-bound; beneficial for maintaining vigor.
Checklist
Choose appropriate pot size; use fresh soil; ensure good drainage; water lightly 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 without saturating the soil; water early in the day to minimize evaporation and fungal growth.
Watering Schedule Tips
Water deeply once the top inch of soil feels dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or sand for drainage; incorporate compost for fertility; ensure soil is loose and airy.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, or stunted growth in extreme heat; leaf drop or frost damage in cold.
Cold Stress
Plants may become dormant or suffer tissue damage in temperatures below 32°F (0°C).
Solution: Protect with a frost cloth or move to a sheltered location; avoid overwatering in cold conditions.
Hot Stress
Leaves may scorch, wilt, or drop in prolonged heat above 85°F (29°C).
Solution: Provide shade during peak heat; increase humidity; water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; apply during growing season; avoid winter feeding.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks during active growth (spring and early summer); avoid fertilizing in winter.
