Environmental Needs
- Climate: {"temperatureRange":"5–20°C"}
- Hardiness: {"zones":"7–9"}
- Misting: rarely required, only if ambient humidity is very low

- Maintenance Level: low
- Toughness Level: moderate
- Pruning Frequency: As needed after flowering; remove yellowing or dead leaves throughout the growing season.
- Pruning Intensity: Light pruning; primarily for tidiness and to prevent disease.
Care Details
Ideal Sunlight Coverage:
Bright indirect light for 4–6 hours daily; tolerate partial shade; avoid intense midday sun, especially in summer.
Sunlight Tolerance Tips:
Acclimate gradually to brighter light; protect from direct sun to prevent leaf scorch; adjust placement seasonally to avoid excessive heat or cold.
Care Requirements
Care Difficulty
easymoderate
Sunlight
partial shade to full sun
Rotate plant weekly for even growth; provide shade during peak summer hours; monitor for signs of sunburn.
Watering
every 7–10 days during active growth, reduce in winter
Water deeply but infrequently; ensure soil dries between waterings; adjust frequency based on season and growth stage.
Soil
well-draining, sandy loam with some organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Avoid heavy clay soils; ensure pots have drainage holes; amend with grit if needed.
Temperature
Cool to moderate temperatures, ideally 50–65°F (10–18°C); prefers cooler conditions during dormancy; avoid extreme heat or cold.
Keep away from drafty windows; maintain consistent temperatures; avoid placing near heat sources.
Fertilizing
every 4–6 weeks during spring and summer
Dilute fertilizer to half strength; fertilize only during active growth; stop before dormancy.
Propagation
Methods
Division of bulbs or offsets; occasionally by seed.
Step-by-Step Propagation Guide
- Carefully dig up bulbs.
- Separate offsets.
- Replant at appropriate depth.
- Water lightly.
Best Time: After flowering, when bulbs are mature; late summer for offsets.
Environment
Cool, shaded environment with moderate humidity; avoid direct sun during rooting.
Medium
Well-draining potting mix with added perlite or sand; can also be propagated in situ by dividing clumps.
Hormone
Not typically required for bulb division; optional for seed propagation.
Timeline
Offsets may take 1–2 years to mature; seeds can take 1–3 years to germinate and establish.
Tools Needed
Garden trowel, clean knife or shears, small pots or designated garden space.
Quick Tips
Handle bulbs gently to avoid damage; ensure offsets have roots before separating; plant at the same depth as the parent bulb.
Pruning & Repotting
Pruning Guide
Method
Snip spent flower stalks at the base; remove dead leaves carefully without damaging the bulb.
Pruning Plan
Minimal pruning required; focus on removing spent flowers and dead foliage to encourage bulb health.
Tools
Clean, sharp scissors or pruners.
Checklist
Remove dead or damaged foliage; cut spent flowers; clean tools after use.
Repotting Guide
Best Season
Late summer or early fall, after dormancy ends but before active growth begins.
Pot Size
Use a pot one size larger if repotting; ensure adequate drainage holes.
Method
Gently lift bulbs; remove old soil; inspect for damage; replant at the same depth in fresh, well-draining soil.
Suggestions
Repot only when bulbs become crowded or every 2–3 years; avoid disturbing bulbs unnecessarily.
Checklist
Check bulb health; use fresh soil; ensure proper depth; water lightly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply at base; ensure drainage; adjust for season.
How to Apply Water Properly
Water directly at the base of the plant, ensuring moisture reaches the root zone without wetting foliage; allow excess water to drain freely; water in the morning to minimize evaporation and fungal risk.
Watering Schedule Tips
Water sparingly during spring growth, allowing soil to dry slightly between waterings; reduce watering significantly in summer dormancy and winter; avoid overwatering to prevent rot.
Soil Improvement
Add perlite or coarse sand to improve drainage; incorporate compost for fertility; ensure soil is loose and airy.
Temperature Stress Management
Signs of Temperature Issues
Yellowing or browning leaves; stunted growth; bud drop; wilting despite adequate water.
Cold Stress
Low temperatures can halt growth and cause root damage; prolonged cold may lead to tissue death.
Solution: Protect from frost; move indoors during cold snaps; ensure good air circulation to prevent mold.
Hot Stress
Excessive heat can cause leaf scorch, wilting, and premature dormancy; may lead to dehydration.
Solution: Provide shade during peak heat; increase humidity; water more frequently but carefully to avoid root rot.
Fertilizing Guide
Fertilizing Checklist
Use balanced fertilizer; dilute properly; apply during growing season; avoid dormant periods.
Fertilizing Method
Use a balanced, diluted liquid fertilizer every 4–6 weeks during active growth (spring); avoid fertilizing in summer dormancy or winter.
