RUBY BALL IMPROVED

RUBY BALL IMPROVED

Product Description:

78 days. Over the years, we have tested hundreds of cabbage varieties at our London Spring research farm, and Ruby Ball Improved remains a great all-season red cabbage. Firm, 6–8 inch round heads have a mild, sweet flavor and weigh a manageable 3–4 pounds. We have seen this variety stand unfazed in the garden for 6 weeks without splitting, which allows the gardener extended fresh harvests. Ruby Ball Improved stores moderately well after harvest.

Ruby Ball

First time trying Ruby Ball cabbage. My seedlings didn’t all germinate and I am having trouble with them growing strong. I live in the mountains at 7000 ft and don’t think they will survive when I set them out. They are still inside and protected. They are tiny and aren’t strong enough to withstand our winds and cool nights. My regular green cabbage seedlings are strong, big and thriving. They are ready to be set outside this week the 2nd week of June. I have to search for varieties of vegetables that have the ability to withstand cooler temps.

So sorry to hear that! We do germ test all of our seeds and to ensure we sell only top performing seed, we have established germination standards that are higher than prescribed by the Federal Seed Act. Our minimum germination standard for cabbage is 75% and the most recent test for this variety passed at 89%. As always, our products are backed by our full guarantee. We want you, our customers, to be 100% satisfied with the seed, plants and supplies that you purchase from us. If anything you buy from Territorial proves to be unsatisfactory, we will either replace the item (if available) or refund the purchase price, whichever you prefer (for up to 1 year from purchase). You can also reach out to us for any troubleshooting! Contact our customer service (Monday-Friday 8AM-5PM Pacific Time) at either 800-626-0866 or info@territorialseed.com

Brassica oleracea, Capitata Group Cabbage holds the esteemed position of the vegetable that contains the least amount of fat per serving. As an excellent source of vitamin C and antioxidant phytonutrients, cabbage is a great defender against cancer. Red cabbage is rich in anthocyanins, which have anti-inflammatory properties.

Days to maturity are calculated from date of transplanting; add 25-35 days if direct seeding.

Culture
• Sudden temperature changes or high applications of fertilizer may result in poor head shape and reduced yields
• Consistent and even watering is necessary

Direct Sowing
• Sow March—June
• Not recommended for fall plantings

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

Insects & Diseases
• Common insects: See Brassica Insect Information below
• Disease prevention: 5-7 year crop rotation

Harvest & Storage
• Early types: Mature fast and burst quickly, so they must be harvested promptly
• Later types: Hold in the field longer
• When cutting heads from stems, include 2 or 3 wrapper leaves to protect against bruising
• Over-mature heads can split, especially if they are exposed to moisture fluctuations
• Late storage types will keep for up to 6 months when kept at 36°F and at 100% relative humidity; early types will store 1-2 months

Brassica Insect Information
Aphids: Control aphids with ladybugs or a hard spray of water 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.
