Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily). Tolerates partial shade but may produce fewer blooms.
Sunlight Tolerance Tips:
Acclimate plants gradually if moving from shade to sun. Protect from intense midday sun in hot climates. Ensure good air circulation to prevent fungal issues in humid conditions.
Care Requirements
Care Difficulty
easymoderate
Sunlight
full sun
Full sun is best; rotate pots for even growth; avoid deep shade.
Watering
every 7–10 days during active growth, less frequently in winter
Water thoroughly but infrequently; ensure soil dries between waterings; avoid overwatering to prevent root rot.
Soil
well-draining, sandy loam with moderate organic content
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure good drainage; amend with organic matter; avoid heavy clay soils.
Temperature
Prefers warm temperatures (65–85°F or 18–29°C). Tolerates heat well but may struggle in prolonged extreme heat or frost.
Protect from frost; water deeply in heat; ensure good air circulation.
Fertilizing
every 4–6 weeks during spring and summer
Use a balanced fertilizer; dilute to half strength; fertilize during active growth only.
Propagation
Methods
Stem cuttings or division. Stem cuttings are the most common method for home growers.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Dip in rooting hormone (optional).
- Plant in medium.
- Keep moist and warm.
Best Time: Late spring to early summer when the plant is actively growing.
Environment
Warm (70–75°F or 21–24°C), humid environment with indirect light.
Medium
Well-draining potting mix (e.g., perlite and peat moss) or vermiculite.
Hormone
Rooting hormone is optional but recommended for faster rooting.
Timeline
Roots typically form in 2–4 weeks; plants can be transplanted after 6–8 weeks.
Tools Needed
Pruners, rooting hormone, small pots, well-draining medium.
Quick Tips
Use healthy, non-flowering stems; keep consistently moist; provide bottom heat if possible.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips to encourage branching; cut spent flowers just above a leaf node.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove spent flowers to prolong blooming.
Tools
Clean, sharp pruners or scissors.
Checklist
Use clean tools; prune dead or damaged stems; deadhead regularly; shape as needed.
Repotting Guide
Best Season
Early spring before new growth begins.
Pot Size
Increase pot size by 1–2 inches in diameter.
Method
Gently remove the plant; trim any dead roots; place in a slightly larger pot with fresh, well-draining soil; water thoroughly.
Suggestions
Repot every 2–3 years or when the plant becomes root-bound. Young plants may need repotting annually.
Checklist
Choose appropriate pot size; use fresh soil; trim roots if necessary; 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 at the base of the plant, ensuring moisture reaches the root zone. Water early in the morning to minimize evaporation and fungal issues. Allow excess water to drain away completely.
Watering Schedule Tips
Water deeply once a week during active growth; reduce frequency in winter to every 2–3 weeks. Adjust based on rainfall and soil moisture.
Soil Improvement
Add perlite or coarse sand to improve drainage; incorporate compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis (yellowing leaves) in excessive heat; stunted growth or bud drop in cold stress.
Cold Stress
Low temperatures slow growth and can cause leaf damage or dieback. Frost can be fatal.
Solution: Provide frost protection in cold climates (e.g., row covers, mulch). Plant in a sheltered location. Avoid overwatering in cool conditions.
Hot Stress
Excessive heat can lead to wilting, leaf scorch, or reduced flowering.
Solution: Water deeply during heatwaves; provide afternoon shade if possible; mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Use balanced fertilizer; dilute properly; apply during growing season; avoid winter feeding.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks during the growing season (spring to early fall). Avoid fertilizing in winter.
