Scallions/Bunching Onions

Red Baron Onion Conventional & Organic

Red Baron Onion Conventional & Organic

ON544

60 days. Long-day variety. An extremely versatile red onion that maintains its vibrant burgundy color at all stages of growth. When planted in the summer, Red Baron can be harvested in the early fall as a scallion. When plants reach 12-14 inches tall, they will start forming small bulbs, which are mild flavored and wonderful in salads or pickled. In areas that can overwinter onions, Red Baron will form a 3-4 inch bulb the following spring that stores relatively longer than other red onions.

Culture
• Onions are photoperiodic plants — they regulate their stages of growth by day length
• Onions will make top growth until the critical light duration is reached, then bulbing begins
• The amount of growth and development prior to bulbing will determine the bulb size
Long-day varieties do well in northern states where summertime day length is between 14-16 hours
Short-day varieties do well in southern states and bulb when day length is 10-12 hours; they won't get very large in northern states
• Dividing line between short-day and long-day varieties is generally accepted as 36° latitude, roughly along the Kansas/Oklahoma border
Day-neutral and intermediate-day varieties start bulbing when day length is 12-14 hours; generally grow sucessfully anywhere
• Onions prefer light, sandy, loamy soils
• Apply 1/4-1/2 cup of TSC's Complete fertilizer per 5 row feet, 1-2 inches below transplant or seed

Direct Sowing
• Thin to the strongest plant when 4-5 inches

Transplanting
• Sow up to 10-12 seeds in a 4-6 inch pot
• If tops reach over 5 inches before transplant, cut to 3 inches
• When planting out carefully separate the seedlings and place in a shallow trench
• Fill trench around seedlings and water in well

Insects & Diseases
Common insects: Onion thrips and maggots
Insect control: Monterey B.t. or Neem oil
Common diseases: See chart below
Disease prevention: 5-7 year crop rotation

Harvest & Storage
• As bulbs approach maturity, withhold water so protective paper can form
• After about half the tops have fallen, push over the remainder; wait about 1 week then harvest
• Cure in a warm (75-80°F), shaded, well-ventilated location until outer skin and necks are dry
• Store in a cool, dry, well-ventilated area
• Check occasionally and immediately remove any sprouting or rotting onions

What is pelleted seed?
Seed that has been coated with a clay-based material to form a larger, round shape. This makes planting by hand or mechanical seeder easier and allows for more controlled sowing of small seeds such as carrots or lettuce. All pelleted seed has a National Organic Program (NOP) approved coating.
