I apologize for any confusion earlier. The term "fire ball poinsettia" may not refer to a specific variety of poinsettia, and it's possible that there might be a local or unique name associated with a particular cultivar.

In general, caring for poinsettias, regardless of the specific variety, involves the following guidelines:

Light:

• Place the poinsettia in a location with bright, indirect light. Avoid direct sunlight, especially during the intense midday sun.

Temperature:

• Poinsettias prefer temperatures between 65-75°F (18-24°C). Avoid exposing them to drafts, cold air, or sudden temperature changes.

Watering:

• Keep the soil consistently moist but not waterlogged. Water the plant when the top inch of the soil feels dry. Ensure the pot has drainage holes.

Humidity:

• Poinsettias appreciate higher humidity levels. You can increase humidity by placing a tray of water and pebbles near the plant or using a humidifier.

Fertilization:

• Fertilize the poinsettia with a balanced, water-soluble fertilizer every 2-4 weeks during the growing season (spring and summer). Reduce or stop fertilizing in the fall and winter.

Pruning:

• If you want a bushier plant, pinch back the tips of the stems in early summer. Be cautious not to prune too late in the season as it may affect flowering.

Reblooming (optional):

• If you want the poinsettia to rebloom the following year, it requires a period of darkness for about 12-14 hours each night starting in late September or early October. This mimics the natural conditions that induce flowering.

If "fire ball" is a specific cultivar or if there are unique care requirements associated with it, I recommend checking with the plant's supplier or the specific nursery where it was obtained for more detailed information.
