Cultivation Factors
Environmental Factors
Temperature: The Sunflower’s Thermostat
Like most living beings, sunflowers thrive within a specific temperature range. Optimally, they bask in temperatures between 60-85°F (16-29°C). When temperatures soar above this range, sunflowers may wilt and struggle to absorb essential nutrients. On the contrary, when the mercury dips below 50°F (10°C), these golden giants shiver and their growth slows considerably.
Extreme temperatures can hasten a sunflower’s demise. Prolonged exposure to scorching heat damages their leaves and flowers, leading to sunburn and dehydration. In contrast, freezing temperatures can shatter their stems and freeze the delicate sap within, causing irreversible damage. Therefore, providing your sunflowers with a constant and moderate temperature is crucial for their well-being and longevity.
