It is the time of year when people flock to sunflower fields and capture the beauty of the flower, but what does it take for sunflowers to thrive?


What You Need To Know

  • Sunflowers peak in the summer

  • These flowers like temperatures in the 70s and ample sunshine

  • There are several sunflower farms throughout Wisconsin

Sunflowers' keys to success

As someone who studied meteorology and agricultural sciences in college, I always like seeing what conditions certain crops grow best in. And when it comes to the ever-popular sunflower, I thought I'd take a closer look.

Let's start with the amount of light it requires. As the name suggests, sunflowers do best in ample sunshine. Since sunflowers are heliotropic (they follow the sun), more sunlight leads to the plant remaining straight.

As for water, like most plants, an average amount of water is necessary. What does that mean? Check the soil conditions. If the soil is too dry, you will need to water. If the soil is over-saturated, you will need to allow time for it to dry out.

During periods of drought, a sunflower will stop blooming. Despite Wisconsin seeing some serious stretches of drought this summer, it seems that the sunflowers fields were still able to succeed (I'm sure with the help of additional watering).

Finally, let's talk about temperatures. I definitely have something in common with sunflowers: I love temperatures in the 70s. And sunflowers do best when the temperature is anywhere from about 70 to 78 degrees.

This is good news for Wisconsin farmers due to the cooler temperatures we see during the summer months.
