Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily); tolerates partial shade but may become leggy with insufficient light.
Sunlight Tolerance Tips:
Acclimate new plants to full sun gradually over 1–2 weeks; protect from intense midday sun in summer; ensure good air circulation to prevent fungal issues.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun
Full sun is essential; avoid deep shade; rotate pot for even growth.
Watering
every 7–10 days during active growth, reduce to every 3–4 weeks in winter
Water thoroughly but infrequently; ensure soil dries between waterings; avoid overwatering, especially in winter.
Soil
well-draining, sandy or loamy soil with low organic content
pH: Slightly acidic to neutral (pH 6.0–7.0)
Ensure soil dries between waterings; avoid heavy clay soils; amend with grit for drainage.
Temperature
Thrives in warm conditions (65–85°F / 18–29°C); tolerates mild frosts but prefers frost-free environments.
Protect from frost; ensure good air circulation; adjust watering with temperature changes.
Fertilizing
every 6–8 weeks during spring and summer with a balanced, low-phosphorus fertilizer
Dilute fertilizer to half strength; apply to moist soil; avoid contact with roots.
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 (70–80°F / 21–27°C), high humidity (70–80%), and bright indirect light.
Medium
Well-draining mix of perlite and peat moss or cactus mix
Hormone
Recommended to use rooting hormone for better success.
Timeline
Roots may develop in 4–8 weeks; establish in new pot after 3–6 months.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining medium
Quick Tips
Use fresh cuttings; maintain humidity with a plastic cover; avoid direct sun during rooting.
Pruning & Repotting
Pruning Guide
Method
Selective cutting of stems to shape the plant; remove crossing or weak branches.
Pruning Plan
Prune to maintain shape, encourage bushiness, and remove dead or diseased growth.
Tools
Pruning shears, sterilizing solution, gloves
Checklist
Sterilize tools; prune during dormancy; remove dead/diseased parts; shape evenly.
Repotting Guide
Best Season
Early spring before active growth starts.
Pot Size
Increase pot size by 2–3 inches in diameter.
Method
Remove plant gently; trim roots if necessary; repot in fresh, well-draining soil with a slightly larger pot.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for younger plants to encourage growth.
Checklist
Use fresh soil; ensure good drainage; handle roots carefully; water lightly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; ensure drainage; adjust frequency seasonally.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone; allow water to drain freely; water early in the morning to minimize evaporation and fungal risk.
Watering Schedule Tips
Water deeply once every 7–10 days during active growth in spring and summer; reduce frequency to every 3–4 weeks in fall and winter. Adjust based on rainfall and soil dryness.
Soil Improvement
Add perlite, coarse sand, or pumice to improve drainage; incorporate compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis or leaf drop in extreme cold; wilting or scorching in excessive heat.
Cold Stress
Growth slows or halts; leaves may turn yellow or brown; risk of root rot if soil remains wet in cold.
Solution: Provide frost protection in winter; ensure well-draining soil; reduce watering in cold periods.
Hot Stress
Leaves may wilt, scorch, or drop; growth may slow; increased water demand.
Solution: Provide afternoon shade if possible; increase watering frequency; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Use low-phosphorus fertilizer; dilute properly; fertilize during growing season only.
Fertilizing Method
Use a balanced, low-phosphorus fertilizer (e.g., 5-10-5) every 4–6 weeks during spring and summer; avoid fertilizing in fall and winter.
