Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily). Tolerates partial shade but may become leggy.
Sunlight Tolerance Tips:
Acclimate new plants to full sun gradually to prevent scorching. Place in a location with unobstructed sunlight outdoors; indoors, use a south-facing window.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun
Rotate plant for even growth; use sheer curtains to filter intense midday sun; avoid sudden light changes.
Watering
every 2–3 weeks, less in winter
Water thoroughly but infrequently; allow soil to dry between waterings; avoid overwatering, especially in winter.
Soil
well-drained, loamy soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes; use a cactus/succulent mix as a base; avoid overwatering to prevent compaction.
Temperature
Tolerates a wide range (20–30°C ideal), but can survive temperatures down to -7°C. Prefers warm, dry conditions.
Avoid placing near drafty windows or heat sources; protect from frost in winter; ensure good air circulation in hot weather.
Fertilizing
every 3–4 months during active growth
Fertilize only during active growth; use a balanced formula; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings or seeds. Stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Take a 10–15 cm cutting.
- Remove lower leaves.
- Apply rooting hormone.
- Plant in medium.
- Keep moist and warm.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm (20–25°C), humid environment with bright, indirect light.
Medium
Well-draining mix of perlite and peat moss, or cactus/succulent soil.
Hormone
Rooting hormone is recommended to improve success rates.
Timeline
Roots may develop in 4–8 weeks; establishment can take several months.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining medium.
Quick Tips
Use healthy, non-flowering stems; maintain consistent moisture; provide bottom heat if possible.
Pruning & Repotting
Pruning Guide
Method
Selective thinning and heading back to shape the plant and improve air circulation.
Pruning Plan
Prune to maintain shape, remove dead/damaged branches, and encourage bushier growth.
Tools
Pruning shears, loppers (for larger branches), gloves.
Checklist
Use sharp, clean tools; make cuts at a 45-degree angle; remove dead or crossing branches; disinfect tools between cuts.
Repotting Guide
Best Season
Early spring before the growing season begins.
Pot Size
One size larger pot (e.g., +5–7 cm in diameter).
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. Necessary to refresh soil and provide space for growth.
Checklist
Choose appropriate pot size; prepare fresh soil mix; handle roots carefully; water after repotting; place in shade for a few days.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; ensure proper drainage; adjust frequency seasonally.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone. Water until it drains from the bottom, then allow excess to drain away. Water early in the morning to minimize evaporation.
Watering Schedule Tips
Water deeply every 1–2 weeks during active growth (spring/summer), reducing frequency to monthly in winter. Adjust based on rainfall and soil dryness.
Soil Improvement
Add coarse sand, perlite, or compost to improve drainage and aeration. Avoid heavy clay soils.
Temperature Stress Management
Signs of Temperature Issues
Leaf drop, wilting, or browning leaf edges in extreme heat; stunted growth or leaf discoloration in cold stress.
Cold Stress
Low temperatures slow growth and can damage leaves and branches, especially if prolonged or coupled with wet soil.
Solution: Protect from frost with frost cloth or mulch; ensure soil is well-drained to prevent root rot; move potted plants to a sheltered location.
Hot Stress
Excessive heat can cause leaf scorch, wilting, and reduced vigor, especially if combined with drought stress.
Solution: Provide partial shade during peak heat; increase watering frequency; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Use appropriate fertilizer; apply at correct dilution; fertilize during growing season only; avoid contact with roots.
Fertilizing Method
Use a balanced, slow-release fertilizer in spring. Dilute liquid fertilizer to half-strength if used monthly during growing season. Avoid fertilizing in winter.
