Growing Tips

Edible Flowers

When to Start

 

Spring: Start indoors 4-6 weeks before the last frost date. (April/May for GA)

Direct Sow: After the danger of frost has passed.

How to Grow

 

Start indoors 4-6 weeks before the last frost date or direct after all danger of frost has passed. Sow the seeds into seed cells to a depth of 1/4 inch. Celosia seeds need the dark to germinate. Seeds can be a little slow to germinate and can take 2-3 weeks before sprouting. Transplant after hardening off and after all danger of frost has passed. Thin or space 9-12 inches apart.

 

Care

 

Celosia likes full sun and can tolerate a wide range of soil conditions. Keep the soil moist during germination and establishment to prevent water stress. Once Celosia has established it is drought tolerant. If growing for cut flowers, it is recommended to cut the main flower stem once the plant reaches 12” tall. This will encourage the plant to create more branches for more flowers versus having only one main stock.

Humidity can create problems for celosia, space plants further apart to create more air circulation.

Seed Saving

Isolation Distance

 

Self-pollinating. However, insects can cross-pollinate with different varieties. Separate different varieties by 1/4 mile.

 

Instructions

 

Select healthy, robust plants free of any signs of disease or insect infestation for seeds. Seeds carry the traits of the parent plant. Choose plants that exhibit the traits you wish to preserve. Consider bloom size, color, and shape, as well as blooming time.

Allow the biggest and healthiest blooms to mature on the plant.

Clip the flower head from the stem once the flower head has turned brown. Place the flower head in a paper bag and shake it to loosen the seeds. The seeds should readily shake from the pods. Seeds settle to the bottom of the bag. Remove plant debris by hand.
