Tulip guides list aphids, tulip fire, gray mold, virus symptoms, and bulb rot among possible problems. The outdoor source does not make any symptom diagnostic.
How to care for indoor tulips
For indoor tulips, chill planted bulbs in darkness at roughly 4.4–7.2°C for 12–16 weeks before moving them into light.

Find a bright, steady position
Light and temperature
Indoor forcing uses approximately 4.4–7.2°C in complete darkness for about 12–16 weeks before the flowering phase. This is a cold-treatment requirement, not a year-round room target.
Check the mix, drainage and pot
Watering, drainage and repotting
Water thoroughly after planting and keep the potting mix from drying during cold storage, while avoiding sodden compost. This is seasonal forcing guidance, not a year-round indoor schedule.
Use a well-drained commercial potting mix in a container with drainage holes, and plant the bulb with its nose slightly above the mix. No hybrid-specific repot practice is established.
Feed only during active growth
Fertilizer and active growth
For garden or outdoor-container growth, RHS recommends a potassium-rich liquid fertilizer weekly from March while tulips are growing. That interval is not validated for every forced indoor hybrid.
