How to grow

Sow seeds indoors in trays or pots 4 to 6 weeks before your last frost. Zinnias are very cold sensitive, so wait until all danger of frost has passed before planting outside. Zinnias can also be direct-seeded into the garden once weather is consistently warm.

Harvesting & Vase Life

Use the “wiggle test”: Grab the stem about 8 in down from the flower and gently shake it. If the stem is droopy or bends, don’t cut yet. If the stem is stiff and remains erect, it is ready to harvest. Zinnias are notorious for making their water murky. To combat this, add a few drops of bleach to the water. Expect a vase life of 7 days.
