Learn how to grow celosia from seed and enjoy these unusual, colorful blooms in the garden or in bouquets all summer long!
Celosia seeds
Celosia seeds are tiny black spheres. You should start the seed indoors for 4 to 6 weeks before planting outdoors.
Planting Celosia seeds
Bury the seeds about 1/4 inch into the soil. Cover the seed starting tray with plastic wrap to keep the soil moist, opening once a day for air circulation. Keep the soil moist by misting but not too soggy.
Temperature and Humidity
Keep the temperature between 70 and 80 degrees during the 7 to 14 day germination process.
Watering
Keep the soil moist during the germination period, but not soggy. Once the seedlings are up allow the soil to dry out some before hardening.
Lighting
Celosia seedlings need light to germinate; so place the seed tray in natural or artificial light daily.
Hardening off
To prevent transplant shock, acclimate your celosia seedlings to outdoor conditions by gradually increasing their exposure to outdoors once night temperatures are above 55 degrees.
