Comet Radish Seeds (25 days)

AAS winner


A very popular market radish in the 1950's, the Comet radish has a long history, including an All American Selections Win in 1936.

Comet radish has a ruby red skin and crisp snow white flesh, with a globed and almost perfectly round shape, making it a popular super market variety for years. 

Comet radish is early at 25 days and many enjoy its crunchy flesh earlier at only 3/4" to 1" in diameter.  

One of the few radishes that can be grown in hot weather and still develop to size. 

1942 Burpee Seed Catalog says about comet radish seeds...."Bred to meet the increasing demand for an early radish that has the same qualities as Vick's Scarlet Globe, but with a rounded instead of an olive-shaped root.  Comet fille the bill; the roots are globe to olive-shaped, small tap-roots, bright scarlet and for eating and keeping qualities it is surpassed by none; it will remain crisp and solid for a long time."

Planting Tips for Heirloom Radishes:

Radishes are a cool season crop and are quick to mature.  These heirloom seeds can be planted in spring or fall.  Due to the small size of these seeds and vegetables, most people will use a furrow technique when planting.  Sow in shallow furrow and cover with ¼” of sifted compost or light sand.  Later after the first few true leaves appear, it is best to then thin to final spacing.  Remember, larger spacing will result in larger heirloom radishes but they will take longer to mature.

Be sure to seed every few weeks if you desire a steady crop of heirloom radishes out of your garden.  Nothing can be easier to grow.  Consistent watering will tend to elimnate woody roots and make a better tasting radish.

Seeding Care for Heirloom Radishes:

Heirloom seeds are hardy, but always take care with your garden seeds to give them the appropriate amount of moisture - don't let the vegetable seeds dry out prematurely, and don't overwater and possibly have them rot.
