Starting Celosia from Seed
For earliest bloom time, sow seeds indoors 4-6 weeks prior to last frost. To start indoors, fill individual peat pots with a fertile commercial soil starter and moisten. Celosia does not perform well when roots are disturbed so bury seeds ¼” into the soil. Place in a room with a constant temperature of 65-70°F. Cover with clear plastic wrap to maintain the soil moisture and temperature. Keep the soil moist. When seedlings appear, remove the plastic wrap and move to a sunny location.
You can start hardening off seedlings when temperatures reach above 55°F. For the first few days place in a protected area for a few hours gradually increasing the length of time they are exposed to the elements.
In warmer climates, celosia can be sown from seed directly into the garden. Wait until after the last frost and the soil has reached at least 60°F. Sow liberally ½” below the soil surface. Keep moist until seedlings emerge. Thin to the recommended spacing by keeping only the strongest seedlings.
When to Plant Celosia
Sow seeds indoors 4-6 weeks prior to last frost. Seeds germinate in 14-21 days.
In warmer climates, celosia can be sown from seed directly into the garden following last frost. Soil should be at least 60°F.
