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
- Full sun
- Red Ruby Onion seed or seedlings
Growing Instructions:
-
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.
