No, dahlias don't love intense heat; they prefer warm conditions.
Dahlias thrive in warm summer days and cool nights, mirroring their native environment in the mountains of southern Mexico and Central America. Ideal daytime temperatures for dahlias are between 80-85°F (27-29°C), with nighttime temperatures around 65-70°F (18-21°C). When temperatures consistently rise much higher than this, dahlias can suffer.
Here's a breakdown:
- Ideal Conditions: Warm days and cool nights.
- Too Much Heat: Excessive heat can lead to smaller blooms, reduced flower production, and overall stress on the plant.
- Mitigation: In hotter climates, providing afternoon shade and ensuring adequate watering can help dahlias cope. Mulching can also help keep the soil cooler.
Therefore, while dahlias appreciate warmth, extreme heat can be detrimental. Providing them with optimal growing conditions, including protection from intense sun and consistent moisture, is essential for healthy growth and abundant blooms.
