Celosia Seeds,
Asian Garden

Plant this one only once frost is behind you: start seed indoors 3 to 4 weeks before a transplant date that falls after your last frost, or sow in place after frost. Expect germination in 14 to 21 days at 65-70 F, with the seed covered no more than 1/8 inch in fine, moist soil, since light aids germination. Plants want full sun and 6 to 8 inches of space, and they begin flowering about 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.
