Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours/day) with some afternoon shade in hot climates; adjust for seasonal light intensity.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight; protect from harsh afternoon sun; adjust placement based on indoor/outdoor conditions.
Care Requirements
Care Difficulty
easymoderate
Sunlight
full sun to partial shade
Rotate plants for even light exposure; use sheer curtains to filter intense sun; monitor for sunburn signs.
Watering
every 7–10 days during active growth, reduce in winter
Water at the base to avoid foliage wetting; ensure soil dries slightly between waterings; avoid overwatering.
Soil
well-draining, loamy soil with average fertility
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure soil is loose and airy; avoid waterlogging; amend with compost annually.
Temperature
Prefers cool to moderate temperatures (60–75°F/15–24°C); tolerates cooler nights and mild frosts.
Monitor microclimates; use shade cloth in summer; protect from late spring/early fall frosts.
Fertilizing
every 4–6 weeks during spring and summer
Fertilize lightly after flowering; avoid feeding in winter; use compost as a natural alternative.
Propagation
Methods
Stem cuttings or division; stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Dip in rooting hormone.
- Plant in medium.
- Maintain humidity.
Best Time: Early spring or late summer when temperatures are moderate and growth is active.
Environment
Warm (65–75°F/18–24°C), humid (70–80%), and bright but indirect light; protect from drafts.
Medium
Well-draining mix of peat, perlite, and sand; or a standard seed-starting mix.
Hormone
Recommended to use rooting hormone for faster and more reliable rooting.
Timeline
Roots typically form in 3–6 weeks; plants may take 1–2 growing seasons to mature.
Tools Needed
Pruning shears, rooting hormone, small pots, misting bottle, plastic bags or propagator.
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 regularly; cut back stems to just above a healthy leaf node or bud.
Pruning Plan
Remove spent flowers to encourage reblooming; trim back after flowering to maintain shape and vigor.
Tools
Sharp bypass pruners, clean scissors, gloves.
Checklist
Clean tools; deadhead spent blooms; trim weak or damaged stems; shape as needed.
Repotting Guide
Best Season
Early spring before new growth begins; avoid repotting during flowering or extreme temperatures.
Pot Size
Increase pot size by 2–3 inches in diameter; ensure good drainage holes.
Method
Gently remove plant; trim roots if crowded; place in new pot with fresh soil; water thoroughly.
Suggestions
Repot every 2–3 years or when roots fill the container; beneficial for rejuvenation and growth.
Checklist
Choose appropriate pot; prepare fresh soil mix; handle roots carefully; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water deeply; ensure drainage; avoid wetting foliage.
How to Apply Water Properly
Water thoroughly until it drains from the bottom, ensuring root zone saturation; water early in the morning to minimize evaporation and fungal issues.
Watering Schedule Tips
Water deeply once a week during active growth, reducing frequency in winter; adjust based on rainfall and soil moisture.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate compost for fertility; use raised beds if drainage is poor.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf scorch, stunted growth, or premature flowering in extreme heat; leaf drop or browning in cold stress.
Cold Stress
Low temperatures slow growth and may cause root damage if not protected; frost can damage tender foliage.
Solution: Mulch heavily in winter; protect from frost with row covers; avoid planting in frost pockets.
Hot Stress
Excessive heat can lead to wilting, flower bud drop, and reduced vigor; may require increased watering.
Solution: Provide afternoon shade; increase watering frequency; use reflective mulch to reduce soil heat.
Fertilizing Guide
Fertilizing Checklist
Choose balanced fertilizer; apply in spring; avoid over-fertilization; water after application.
Fertilizing Method
Use a balanced, slow-release fertilizer in early spring; avoid high-nitrogen formulas; reduce or stop feeding in late summer/autumn.
