How to Grow Early White Grano PRR Onion from Seed
Onion seeds are a cool hardy vegetable that can be sown directly 6-8 weeks prior to final spring frost or about 4-6 weeks before the first autumn frost. Seeds may also be begun indoors for early starts. Soil should be well-tilled, nitrogen-rich, with a pH of 6.0-7.0. For outdoor sowing, create a shallow 1" deep trench for a minimum of 12".
Onion seed is very small, so sprinkle generously into the trench and lightly cover with about 1/4" of soil. As seedlings begin to sprout from the row, trim back to favor the strongest starts every 4-6" apart. "Long-day" onions grow best in the northern half of the country while "short-day" thrives in the southern half.
If you have a long enough growing season, onion seeds can be directly sown in the ground. However, the get a jump start, you can also start them indoors 8 to 10 weeks before your last frost date. The early greens on indoor onion seedlings can be trimmed and eaten or left alone to help the bulb grow. If you'll have indoor seedlings for several weeks, trimming the greens can help prevent tangling and help produce stronger plants.
TIP: Remember, Organic onions are shallow rooted and benefit from ample amounts of water to form proper bulbs. About an inch a week.
Early White Grano PRR Onion in the Vegetable Garden
Onion is a cold hardy favorite able to be sown in either spring or fall for an effortless biannual harvest. Onions are often started in the garden from store-bought bulbs, but growing from seed allows for a greater variety of selection among the red, yellow, white, and sweet cultivars.
Early White Grano forms large globe shaped vidalia-type onions. Early White Grano is a short day variety, but works well as an indeterminate day variety of onion as well. When planting, look to see if a "long-day" or a "short-day" onion variety is best suited for the summers in your region. Try an onion crop in the garden bed alongside similar garlic, shallots, or leeks.
Harvesting Early White Grano PRR Onion
Most onions sown in the spring are ready for harvest about 90 days from sowing and seeds planted in the fall can mature as early as May or June the following year. Onions are ready to harvest once the plants" greens have dried out, yellowed, and begun to bow over. Loosen the soil from the bulb to check for consistent coloring while allowing the bulb to further dry. Sweet onions do not store as well as more pungent yellow and brown varieties.
