Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours/day); tolerates partial shade but blooms best in direct light.
Sunlight Tolerance Tips:
Acclimate gradually to intense sun; protect from harsh afternoon sun in hot climates; ensure good air circulation.
Care Requirements
Care Difficulty
easymoderate
Sunlight
full sun
Rotate plant for even light; use sheer curtains in intense sun; avoid sudden light changes.
Watering
every 7–10 days during active growth, less frequently in winter
Water thoroughly but infrequently; ensure soil dries between waterings; avoid overwatering.
Soil
well-drained, rocky, or sandy soil with low fertility
pH: Slightly alkaline to neutral (pH 6.5–7.5).
Use gritty mix; avoid heavy clay; ensure pots have drainage holes.
Temperature
Hardy in USDA zones 4–8; tolerates cold but prefers moderate temperatures (60–75°F); heat-tolerant once established.
Protect from frost; avoid sudden temperature swings; adjust watering for heat.
Fertilizing
every 4–6 weeks during spring and summer
Fertilize during active growth; avoid over-fertilizing; flush soil occasionally to prevent salt buildup.
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 hormone.
- Plant in medium.
- Keep moist.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm (70–75°F), humid, and bright indirect light.
Medium
Well-draining mix like perlite and peat moss or cactus soil.
Hormone
Rooting hormone is recommended for faster rooting.
Timeline
Roots in 3–6 weeks; establish in 2–3 months.
Tools Needed
Pruners, rooting hormone, small pots, well-draining medium.
Quick Tips
Use healthy, non-flowering stems; maintain humidity with a plastic cover; avoid direct sun.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips for bushiness; cut back stems to healthy nodes.
Pruning Plan
Prune to maintain shape, encourage bushiness, and remove dead/damaged growth.
Tools
Pruning shears, gloves, disinfectant.
Checklist
Disinfect tools; prune dead/damaged growth; shape plant; clean up debris.
Repotting Guide
Best Season
Early spring before active growth begins.
Pot Size
One size up (e.g., +2 inches in diameter); avoid oversized pots.
Method
Remove plant gently; trim roots if needed; use fresh well-draining soil; ensure drainage holes.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for growth and soil health.
Checklist
Check root bound status; prepare new pot; use fresh soil; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water deeply; ensure drainage; adjust for season.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone; allow excess water to drain away; water in the morning to minimize evaporation.
Watering Schedule Tips
Water deeply once the top inch of soil is dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or sand for drainage; incorporate compost for fertility; ensure good aeration.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf scorch, stunted growth, or premature leaf drop.
Cold Stress
Slows growth; may cause leaf drop or dieback in extreme cold; roots can freeze in poorly drained soil.
Solution: Mulch heavily in winter; protect from frost; ensure well-drained soil to prevent root damage.
Hot Stress
Leaf scorch, wilting, or reduced flowering in prolonged heat; may require more frequent watering.
Solution: Provide afternoon shade; increase watering; use mulch to retain moisture.
Fertilizing Guide
Fertilizing Checklist
Check season; dilute fertilizer; apply to moist soil; rinse pot periodically.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength; apply monthly in spring/summer; avoid fertilizing in fall/winter.
