How to Grow Zinnias for Cut Flowers

Follow these easy steps to grow zinnias in a cut flower garden.

  1. Plant zinnia seeds or starts after the threat of frost has passed. Your zinnias may not survive if planted out when the weather is still too cold.
  2. Leave sufficient space between plants to reduce chances of powdery mildew later in the season. The appearance of powdery mildew can tarnish the appearance of zinnias you plan to cut for indoor vases. Space them out at least 12 to 18 inches for larger varieties and 6 to 8 inches for smaller ones like dwarf zinnias.
  3. Water as needed, taking care not to splash the leaves if possible. Keep the foliage dry for best chances of avoiding mildew or fungus.
  4. Deadhead spent zinnia blossoms to keep the flowers coming. Zinnias will continue blooming rather than switching the focus to seed production. (Learn more about deadheading zinnias.)
  5. Cut and come again. Prolific zinnias should produce plenty of flowers to cut and keep your garden looking amazing!
