Rex Begonia 'Curly Fireflush': Care and Dormancy

Identifying Your Begonia

Your plant is likely a Rex Begonia 'Curly Fireflush'—known for its striking spiraled foliage with reddish undersides. These rhizomatous begonias have specific needs but reward with stunning leaves.

Light & Temperature

• Best: Eastern or western exposure (partial sun). Tolerates low light but colors intensify with some direct morning/afternoon sun.
• Winter: Provide as much light as possible. Temperatures above 60°F (16°C).

Watering: The Weight Method

Rex begonias rot easily if kept too wet. Water by pot weight:

1. Water thoroughly until drainage occurs. Feel the pot's weight—this is "wet weight."
2. Wait until the pot feels considerably lighter and the soil surface is pale, not dark.
3. Water again. Frequency varies from days to weeks depending on conditions.

Winter Dormancy

Rex begonias often enter a semi-dormant period in winter. Leaves may look dull or drop. Do not overwater. Keep barely moist, provide light, and avoid cold drafts. They revive in spring.

Key Takeaway

If the plant appears to "die" in winter, it's likely dormant, not dead. Resume normal care in spring—new growth will emerge from the rhizome.
