How to grow productive Zinnia flowers from seed in your backyard

Gardeners across the world have fallen in love with Zinnia flowers, and the good news is they are really easy to grow from seed! 

Zinnias don't like being transplanted. So if you live in a warmer climate sow Zinnia seeds direct where they will grow, germination should occur in 3-7 days depending on soil temperature.

If you live in a cooler climate, you will need to start them in a greenhouse environment. Using peat pots (biodegradable pots) that can then be directly sown into the ground will help prevent transplant shock. Transplant when they are young and if transplanting from regular pots try not to disturb the root system. 

Zinnias are frost sensitive, so wait until the last frost has passed to plant.

Zinnias are heat lovers, so plant in full sun with good air circulation, this will prevent them from getting powdery mildew. 

Space between 15 - 30cm apart (depending on the variety) and rows 30 - 45cm apart. 

When established try not to water the leaves, water the base of the plant. They don't like to be water logged.

Zinnias are annuals, when flowering, deadheading any flowers that have died will encourage more to grow!
