Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily); tolerates partial shade but may produce fewer leaves.
Sunlight Tolerance Tips:
Acclimate plants to full sun gradually if moved from shade; protect from intense midday sun in hot climates; ensure good air circulation to prevent fungal issues.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Rotate plant for even growth; use sheer curtains to filter harsh sunlight; place outdoors in summer for optimal growth.
Watering
every 7–10 days during active growth, less frequently in winter
Water thoroughly but infrequently; ensure soil dries between waterings; avoid wetting foliage.
Soil
well-draining, loamy soil with moderate organic content
pH: Slightly acidic to neutral (pH 6.0–7.0)
Use a cactus or succulent mix as a base; avoid heavy clay soils; ensure pots have drainage holes.
Temperature
Prefers warm temperatures (65–85°F or 18–29°C); thrives in Mediterranean climates; sensitive to frost.
Protect from frost; avoid sudden temperature changes; maintain consistent warmth for best growth.
Fertilizing
every 4–6 weeks during spring and summer
Apply fertilizer after watering to prevent root burn; stop fertilizing in fall to prepare for dormancy; use organic options like compost tea for gentle feeding.
Propagation
Methods
Stem cuttings
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
Medium
Well-draining mix of perlite and peat moss or cactus mix
Hormone
Recommended to use rooting hormone for faster root development
Timeline
Roots typically form in 3–6 weeks; new growth may appear in 2–3 months
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining medium
Quick Tips
Use healthy, non-flowering stems; maintain high humidity with a plastic cover; keep out of direct sunlight.
Pruning & Repotting
Pruning Guide
Method
Cut back stems to just above a leaf node or bud; remove any dead or diseased wood
Pruning Plan
Prune to maintain shape, encourage bushiness, and remove dead or weak growth; best done in spring before new growth begins.
Tools
Pruning shears, sharp knife, gloves
Checklist
Sterilize tools; prune in early spring; remove dead wood; shape the plant; clean up debris.
Repotting Guide
Best Season
Spring, just before the growing season begins
Pot Size
One size larger pot (e.g., from 4-inch to 6-inch pot)
Method
Remove plant gently; trim any circling roots; place in a slightly larger pot with fresh, well-draining soil; water thoroughly after repotting
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for maintaining vigor and preventing root-bound conditions.
Checklist
Choose appropriate pot size; prepare fresh soil mix; gently remove plant; prune roots if necessary; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water deeply; ensure drainage; avoid wetting leaves.
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 reduce evaporation.
Watering Schedule Tips
Water deeply once the top inch of soil feels dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate compost for fertility; ensure soil is loose and airy.
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves, stunted growth, or leaf drop in cold; wilting or scorching in excessive heat.
Cold Stress
Growth slows or halts; leaves may turn yellow or brown; risk of frost damage or death in temperatures below 20°F (-6°C).
Solution: Move to a sheltered location or indoors before frost; use frost cloth for protection; ensure good drainage to prevent root rot.
Hot Stress
Leaves may wilt, scorch, or drop; growth may slow; essential oils may diminish in quality.
Solution: Provide afternoon shade; increase watering frequency; mist leaves during extreme heat; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type; dilute correctly; apply during growing season; avoid winter feeding.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks during growing season (spring and summer); avoid fertilizing in winter.
