Celosia Seeds,
Jessica Mix Cockscomb

Start Jessica Mix indoors 3 to 4 weeks ahead of transplanting out after your last frost, or sow it directly in place once frost has passed. Cover the seed lightly in fine, moist soil and keep it warm, around 75-80 F, until germination; sprouts appear in 14 to 21 days. Space plants 14 inches apart in full sun. Flowering begins around 90 days from sowing.

• Seeds germinate in 14-21 days.
• Surface sow seeds and cover with a layer of soil, making sure that seeds are well covered, as light inhibits germination.
• Direct sow in place after last frost or start indoors 4-6 weeks before last frost.
• Ideal germination temperature is 65-70 F.

• Celosia can handle a wide range of soil and they appreciate full sun.
• Space 9-12 inches apart. Plants range in height from dwarf to 3.5 feet tall depending on variety.
• While the plants are considered drought-tolerant, keep them well-watered during germination and establishment as water stress can cause premature blooming.
• Cut flower growers should pinch the main growing stem when plants reach 12 inches tall to encourage multiple branching versus single chunky stems.

PESTS/SPECIAL CONSIDERATIONS

• Typically pest-free, though aphids may be a problem but can be treated with organic insecticidal soap.
• This warm weather-loving plant may suffer from botrytis and rot if consistently exposed to temperatures cooler than 60 F and high humidity. Space plants farther apart to promote better air circulation and do not plant too early when the weather is still cold.

• Flowers are mostly self-pollinating, but insects can cross-pollinate different varieties. In order to prevent errant insect pollination, separate different varieties by 1/4 mile.
• Save seeds when flower heads have turned brown; just place heads in a paper bag and shake seeds free.
• Keep seeds in a cool, dry dark place.
• Seeds remain viable for 3-5 years when stored properly.
