Best Soil for Sunflowers

It is a beautiful scene to see sunflowers in bloom, especially during summer. The bright-yellow blooms are like smiles on stems to make summer days sunnier. Fortunately, growing sunflowers is quite easy as they are pest-resistant, fast-growing, and heat-tolerant. 

You can use sunflower blooms to decorate your home, just leave them on their stalks for a beautiful garden, or harvest them for their seeds, which make for a tasty snack. If you plan to grow your own sunflowers, here are some tips on choosing the best soil.

Although you can buy starter plants at a home improvement store or a nursery, you can also try growing sunflowers with seeds. Just sow the seeds directly into the soil. If you already have your preferred variety of sunflowers, buy the seeds. Then plant those seeds following these steps:

  • Plant the seed after spring when the soil is at least 60˚F. The best time to plant is between March and May.
  • Plant the seeds in the soil less than 1-inch deep and around 6-inches away from each other. Thin the seedlings when they reach 6-inches in height to leave the healthiest plants with 12-inches of spaces between them.
  • For continuous blooms, keep your planting staggered. Sow a new row of seeds every 2 to 3 weeks. This is a process called succession planting that will give you continuous blooms until winter.
  • It will take between 80 and 120 days for the sunflower seeds to grow from the time you plant the seed in the soil until the flowers bloom. This will depend on the variety too.
