Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours/day); tolerates partial shade but may become leggy.
Sunlight Tolerance Tips:
Acclimate gradually if moving from shade to sun; protect from intense midday sun in hot climates; ensure adequate light indoors near a south-facing window.
Care Requirements
Care Difficulty
very easyeasy
Sunlight
full sun to partial shade
Rotate plant for even growth; use sheer curtains to filter harsh sun; avoid sudden light changes.
Watering
every 7–10 days during active growth, less frequently in winter
Avoid overwatering to prevent root rot; water deeply but infrequently; ensure good drainage.
Soil
well-drained, sandy loam
pH: Slightly acidic to neutral (6.0–7.0).
Use a mix of potting soil and sand; avoid heavy clay soils; ensure pots have drainage holes.
Temperature
Adaptable, but thrives in 60–85°F (15–29°C); tolerates mild frost but prefers warmth.
Avoid sudden temperature swings; protect from frost; ensure good air flow in warm conditions.
Fertilizing
every 4–6 weeks during spring and summer
Fertilize only when actively growing; flush soil occasionally to prevent salt buildup; use a balanced formula.
Propagation
Methods
Stem cuttings or division.
Step-by-Step Propagation Guide
- Take a cutting.
- Let it callus for a few days.
- Plant in medium.
- Keep moist and warm.
Best Time: Spring or early summer when plant is actively growing.
Environment
Warm (70–75°F), high humidity, indirect light.
Medium
Well-draining mix like cactus soil or perlite and peat moss.
Hormone
Optional, but can speed up rooting.
Timeline
Roots in 2–4 weeks; establish in 1–2 months.
Tools Needed
Pruners, rooting hormone (optional), small pots, well-draining mix.
Quick Tips
Use sterile tools; keep cuttings out of direct sun; maintain humidity with a plastic bag.
Pruning & Repotting
Pruning Guide
Method
Cut stems just above a leaf node or junction; remove spent flowers.
Pruning Plan
Remove dead or overgrown stems to maintain shape and encourage bushiness.
Tools
Pruning shears, gloves, disinfectant.
Checklist
Disinfect tools; prune dead/damaged stems; shape as desired; dispose of clippings.
Repotting Guide
Best Season
Spring, before active growth begins.
Pot Size
One size larger pot (e.g., +2 inches in diameter).
Method
Remove plant gently; trim roots if needed; place in new pot with fresh soil; water lightly.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for growth and health.
Checklist
Choose appropriate pot; prepare new soil; handle roots carefully; 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 directly at the root zone, ensuring even moisture without saturating; allow excess water to drain freely; water early in the day to minimize evaporation.
Watering Schedule Tips
Water sparingly, allowing soil to dry between waterings; increase frequency in active growth periods (spring/summer) and reduce in dormancy (fall/winter).
Soil Improvement
Add perlite or sand for drainage; incorporate compost for fertility; ensure aeration with coarse materials.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, stunted growth, or leaf drop.
Cold Stress
Slows growth, may cause leaf discoloration or dieback in prolonged cold.
Solution: Move to a warmer location; protect from drafts; cover if frost is expected.
Hot Stress
Leaf scorch, wilting, or reduced flowering in extreme heat.
Solution: Provide shade during peak heat; increase watering; improve air circulation.
Fertilizing Guide
Fertilizing Checklist
Check growth phase; dilute fertilizer; apply to moist soil; avoid contact with foliage.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength; apply monthly during growing season (spring/summer); avoid fertilizing in fall/winter.
