Red Ruby onions (Allium cepa) is a variety of onion known for their deep red color and mild, sweet taste. They are an excellent choice for salads, sandwiches, and grilling. They are a long-day onion variety, which means they require a longer period of daylight to start forming bulbs.
To grow Red Ruby Onions, you will need:
Well-drained, fertile soil
Red Ruby Onion seed or seedlings
Start seed indoors 8-10 weeks before the last frost date or sow seed directly into the ground in early spring.
Transplant seedlings to the garden after all danger of frost has passed and the soil has warmed up. Space the plants about 3-4 inches apart in rows that are 12-18 inches apart.
Water the onion regularly, keeping the soil consistently moist but not waterlogged.
Fertilize the onion with a balanced fertilizer every 4-6 weeks.
Keep the onion free of weeds and remove any diseased or damaged leaves to help prevent disease.
When the onion tops start to fall over and turn yellow, stop watering and wait a week before harvesting.
