Flash Collards


55 days. Flash is a dark-green-leaved collard that has earned a reputation for its vigor, high uniformity, and impressive yields. The 16-23 inch, smooth, broad-leaved plants are very slow to bolt, offering longer, more dependable harvests. An excellent cutting green with a mild, sweet flavor especially if exposed to a little frost. High in iron, calcium, potassium, phosphorus, and vitamins A, B, C, and E. Rapid regrowth after harvest.

Brassica oleracea, Acephala Group Collards are among the best vegetable sources of vitamin K. This nutrient is said to limit neuronal damage in the brain, aiding in the prevention, or delaying onset of Alzheimer's disease.

Days to maturity are calculated from date of direct seeding.

• Collards are a cool-season crop that performs best in spring and fall
• In wet climates, ensure adequate plant spacing to reduce pest and disease isssues

Direct Sowing
• Cover seed with loose soil, vermiculite, or sifted compost and water evenly
• Sow June—July for a fall crop

• Start indoors 4-6 weeks before anticipated transplant date
• Work in 1/2 cup of TSC's Complete fertilizer around each plant
• Start May—July for transplanting June—August for a fall crop

Insects & Diseases
Common insects: See Brassica Insect Information below
Common diseases: Leaf spot, black rot, fungal diseases, mold, mildew, club root
Disease prevention: Dispose of diseased material, proper crop rotation of 3-4 years, apply Greencure® for mildews

• Store at 36°F and 95% relative humidity

Brassica Insect Information
Aphids: Control aphids with ladybugs or a hard spray of water, Neem oil or Pyrethrin. Also, select varieties that mature later in the season when aphid populations decline.
Cabbage worms, loopers, and root maggots: The first sign of cabbage worms will be off-white butterflies fluttering near the plants. They lay their yellowish-colored eggs on the undersides of leaves, which hatch into caterpillars that can cause severe root and head damage. To control light infestations, spray plants with Bacillus thuringiensis (B.t.). For heavy infestations, bait cabbage worms by mixing wheat bran into a B.t. solution. Add 1 tablespoon of molasses. Broadcast the bran mixture around the base of plants. Reapply as necessary. Using Reemay or Summer Insect Barrier can also provide control.
Flea beetles: Flea beetles chew tiny pinholes in leaves. Early control is essential to minimize the damage. Spray infected plants with Pyrethrin. Using floating row covers such as Summer Insect Barrier can also provide control.
Symphylans: In some areas of the US, symphylans (also known as garden centipede) can severely impede the plant growth of many crops. Only 1/4 inch long, white, and very active, they eat the root hairs of developing plants. Using larger transplants helps reduce damage. Contact your local county extension agent if you suspect you have a problem.

Delicious and Super Easy to Grow

These Flash Collards are some of the best I've tasted - so much better than the variety I see at the store and at roadside stands. Much more tender as well. These were virtually pest-free and grew last year in my South Carolina garden (with subsequent plantings) from fall through early June without bolting or bugs (last seeding in late February).
Best greens in the garden!

I LOVE these collards. I direct sowed them in the garden last July and they survived the near record cold snap we had this winter when most of my kale died. This stuff grows when most things won't and it tastes great. It's April now and all of them are sprouting (the sprouts are delicious!) and the leaves still taste great. If you like cooking greens (or greens in your smoothies) fall through spring, grow this variety. You can't go wrong!
