What Is the Ideal Temperature Range for spotted begonia?
Polka dot begonia exhibits moderate resilience to temperature variations but is sensitive to extremes. It can tolerate cold down to 5℃ (41℉) and withstand heat up to 43℃ (109℉). This tolerance affects care requirements significantly; during cold spells, ensure polka dot begonia is protected from frost, and in extreme heat, provide shading and adequate hydration. Symptoms of distress under cold conditions include leaf drop and darkened edges, while overheating may cause wilting and scorched leaves. To counter overcooling, move polka dot begonia to a warmer spot and consider using a plant cover. For overheating, relocate to a cooler area and increase watering frequency.
