Plant Needs
Sunlight
Full sun to partial shade; host crocus requires consistent bright light to produce viable stigma
Watering
Water host crocus sparingly; allow top 2–3 cm of soil to dry completely between waterings to prevent bulb rot
Temperature
Host crocus is hardy to -10°C; requires cool winter dormancy (5–10°C) to trigger autumn flowering

Care Guide
Watering
Water host crocus lightly every 7–10 days during active leaf growth
Fertilization
Apply diluted balanced liquid fertilizer once monthly during leaf development. Do not fertilize during dormancy, as bulbs are not actively growing
Eggshell powder topdress：Crush dried eggshells into a fine powder; sprinkle a thin layer on the soil surface around host crocus bulbs in early spring to boost calcium levels and improve soil structurePruning
- Remove yellowing foliage from host crocus after flowering to redirect energy to bulb development
- Deadhead spent host flowers promptly to prevent unwanted seed formation
