Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily). Adjust for intense summer sun by providing partial shade during peak hours.
Sunlight Tolerance Tips:
Acclimate gradually if moving from shade to full sun; protect from harsh midday sun to prevent scorching; ensure outdoor placement in open, sunny areas.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun
Rotate plant for even sun exposure; use shade cloth in extreme heat; avoid sudden light changes.
Watering
every 7–10 days during active growth, less frequently in winter
Water deeply but infrequently; ensure excellent drainage; avoid overwatering, especially in winter.
Soil
well-drained, sandy or loamy soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes; avoid heavy clay soils; use gritty mixes for container planting.
Temperature
Prefers warm temperatures (65–85°F or 18–29°C). Tolerates mild frosts but thrives in Mediterranean climates.
Protect from frost; ensure good air circulation in heat; adjust watering with temperature changes.
Fertilizing
every 4–6 weeks during spring and summer, none in winter
Fertilize only in spring; use half-strength if needed; avoid high-nitrogen formulas.
Propagation
Methods
Stem cuttings taken in late spring or early summer.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Dip in hormone.
- Plant in medium.
- Keep moist and warm.
Best Time: Late spring to early summer when new growth is firm but not woody.
Environment
Warm (70–75°F or 21–24°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 3–6 months.
Tools Needed
Pruning shears, rooting hormone, small pots, misting spray bottle.
Quick Tips
Use firm, non-woody stems; maintain humidity with a plastic cover; avoid direct sun.
Pruning & Repotting
Pruning Guide
Method
Selective thinning and heading back to shape the plant and improve air circulation.
Pruning Plan
Prune to maintain shape, encourage bushiness, and remove dead or weak growth.
Tools
Pruning shears, loppers (for larger branches), gloves.
Checklist
Check for dead/damaged branches; sterilize tools; prune before active growth; dispose of clippings.
Repotting Guide
Best Season
Early spring before the growing season starts.
Pot Size
Increase pot size by 2–3 inches in diameter.
Method
Remove old soil gently; trim any circling roots; repot in fresh, well-draining soil with a slightly larger pot.
Suggestions
Repot only when root-bound, typically every 2–3 years. Overpotting can lead to waterlogging.
Checklist
Check root-bound status; prepare new pot with drainage; use fresh soil mix; water lightly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil dryness; water deeply; ensure drainage; reduce in winter.
How to Apply Water Properly
Water thoroughly at the root zone until water drains from the bottom, ensuring even moisture without waterlogging. Water in the morning to allow foliage to dry.
Watering Schedule Tips
Water sparingly, allowing soil to dry completely between waterings. Reduce watering significantly in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand to improve drainage; incorporate compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis or leaf drop in cold stress; wilting or scorching in excessive heat.
Cold Stress
Low temperatures slow growth and may cause leaf drop or dieback, especially below 20°F (-6°C).
Solution: Provide frost protection in winter; move potted plants indoors or to a sheltered location; use mulch to insulate roots.
Hot Stress
Excessive heat can lead to wilting, leaf scorch, or reduced flowering if water and light are not managed.
Solution: Provide afternoon shade; increase watering frequency; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Check season; use balanced fertilizer; apply sparingly; avoid late-season feeding.
Fertilizing Method
Use a balanced, slow-release fertilizer in early spring. Avoid fertilizing in late summer or fall to prevent new growth vulnerable to cold.
