Care Requirements
Care Difficulty
easymoderate
Sunlight
full sun to partial shade
Rotate plant weekly for even growth; use sheer curtains to filter strong light; move outdoors in spring/summer.
Watering
every 7–10 days, allowing soil to dry between waterings
Water thoroughly but infrequently; ensure soil dries between waterings; avoid wetting foliage.
Soil
well-draining, loamy soil with added organic matter
pH: Slightly acidic to neutral (6.0–7.0).
Use a mix with good drainage; avoid heavy clay soils; ensure pots have drainage holes.
Temperature
Ideal range 60–75°F (15–24°C); prefers cooler temperatures in winter.
Avoid sudden temperature changes; protect from drafts; adjust watering with temperature shifts.
Fertilizing
every 2–4 weeks during active growth (spring and summer), with a balanced liquid fertilizer
Fertilize only when actively growing; flush soil occasionally to prevent salt buildup; avoid over-fertilizing.
Propagation
Methods
Stem cuttings
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Dip in hormone.
- Plant in medium.
- Keep moist.
Best Time: Spring or early summer when plant is actively growing.
Environment
Warm (70–75°F), 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 faster root development.
Timeline
Roots develop in 3–6 weeks; new growth appears in 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, misting spray bottle.
Quick Tips
Use healthy, non-flowering stems; keep soil consistently moist but not waterlogged; provide bottom heat if possible.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips, cut above leaf nodes, and remove leggy or crossing stems.
Pruning Plan
Shape plant, encourage bushiness, and remove dead/damaged growth to improve health and appearance.
Tools
Clean, sharp pruning shears or scissors.
Checklist
Sanitize tools; prune during active growth; remove dead/diseased parts; shape evenly.
Repotting Guide
Best Season
Spring, before active growth begins.
Pot Size
Increase pot size by 1–2 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 soil freshness.
Checklist
Check root bound status; prepare new pot with drainage; use fresh soil mix; 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 deeply at the root zone until water drains from the bottom; allow excess to drain; water in the morning.
Watering Schedule Tips
Water when the top inch of soil is dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate compost for fertility; ensure good aeration.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, or yellowing in cold; scorching or stunted growth in excessive heat.
Cold Stress
Slows growth, causes leaf drop, and may lead to root rot if soil remains cold and wet.
Solution: Move to a warmer location; protect from drafts; ensure soil dries between waterings.
Hot Stress
Leaves may scorch, wilt, or drop; growth may slow due to excessive transpiration.
Solution: Provide shade during peak heat; increase humidity; water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Check growth phase; dilute fertilizer; apply to moist soil; stop in dormant season.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); cease in fall/winter.
