- Suitable For:
- Is Weed: No
- Allergenicity: low
Environmental Needs
- Climate: {"temperatureRange":"10–35°C"}
- Hardiness: {"zones":"9–11"}
- Misting: rarely required, only if ambient humidity is very low
- Drainage: Fast-draining to prevent waterlogging.
- Soil Type: Well-draining, loamy soil with added organic matter; tolerates poor soils but performs better with enrichment.
Maintenance Level
- Maintenance Level: moderate
- Toughness Level: moderate
- Pruning Frequency: Annually in late winter or early spring; light pruning can be done after flowering.
- Pruning Intensity: Moderate; remove up to one-third of old growth to rejuvenate the plant.
Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily); tolerates partial shade but blooms less prolifically.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight; protect from harsh afternoon sun in hot climates; ensure good air circulation to prevent leaf scorch.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Rotate plant regularly for even growth; use shade cloth if needed in extreme heat; avoid placing in drafty areas.
Watering
every 7–10 days during active growth, less frequently in winter
Water thoroughly but infrequently to encourage deep roots; ensure soil dries slightly 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 pots have drainage holes; avoid heavy clay soils; amend with organic matter for better aeration.
Temperature
Thrives in warm conditions (65–85°F or 18–29°C); prefers stable temperatures; may struggle below 50°F (10°C).
Avoid sudden temperature fluctuations; protect from frost; maintain consistent warmth during active growth.
Fertilizing
every 4–6 weeks during growing season, none in winter
Avoid over-fertilizing to prevent leggy growth; fertilize after watering to prevent root burn; use organic options like compost for slow release.
Propagation
Methods
Stem cuttings; softwood cuttings root most readily.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Dip in rooting hormone.
- Plant in medium.
- Keep moist and warm.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm (70–75°F or 21–24°C), humid, and bright but indirect light; protect from direct sun.
Medium
Well-draining mix of perlite and peat moss or cactus mix.
Hormone
Recommended to use rooting hormone for faster and more reliable rooting.
Timeline
Roots typically form in 3–6 weeks; establish in new pot within 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining medium, misting bottle.
Quick Tips
Use clean tools to prevent disease; maintain consistent moisture; provide bottom heat if possible for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Selective pruning of individual stems; pinch back tips to encourage branching.
Pruning Plan
Prune to maintain shape, encourage bushiness, and remove dead or overgrown stems; best done after flowering or in early spring.
Tools
Pruning shears, sharp knife, gloves.
Checklist
Sterilize tools; prune dead or diseased wood first; make clean cuts just above a leaf node; dispose of clippings properly.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Increase pot size by 2–3 inches in diameter; ensure good drainage holes.
Method
Remove plant gently; trim roots if necessary; place in a new pot with fresh soil; water thoroughly after repotting.
Suggestions
Repot every 2–3 years or when roots fill the container; beneficial for container-grown plants to refresh soil and provide space.
Checklist
Choose appropriate pot size; prepare fresh soil mix; handle roots carefully; water and place in appropriate light.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply at the base; ensure proper drainage; adjust frequency with seasons.
How to Apply Water Properly
Water at the base of the plant, targeting the root zone; apply until water begins to drain from the bottom; water early in the morning to minimize evaporation and fungal growth.
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 retention.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate compost for fertility; use mulch to retain moisture and improve soil structure.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis (yellowing leaves), stunted growth, bud drop, or leaf necrosis (browning/tissue death).
Cold Stress
Low temperatures slow growth, cause leaf drop, and may lead to frost damage or death in prolonged cold.
Solution: Move potted plants indoors or to a sheltered location; apply a thick layer of mulch for ground plants; use frost cloth for protection during cold snaps.
Hot Stress
Excessive heat can cause wilting, leaf scorch, or reduced flowering; may lead to dehydration if water needs are unmet.
Solution: Provide afternoon shade if possible; increase watering frequency; use mulch to retain soil moisture; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Choose balanced fertilizer; apply at recommended dilution; fertilize during active growth; avoid winter feeding.
Fertilizing Method
Use a balanced, slow-release fertilizer in spring; apply a diluted liquid fertilizer monthly during growing season; reduce or stop in winter.
