Description

F1 Hybrids
Cherry Mountain
Saffron F1 Grano
Diamond Swan F1

One packet yields three different colored, widely adapted, intermediate day length onions. These high-yielding, long keeping varieties include: brilliant red Cherry Mountain and golden-bronze Saffron F1 Grano types, and silvery Diamond Swan F1. All three of these powerhouse hybrids germinate quickly and grow strongly, producing heavy early yields of firm, big, crunchy bulbs with shiny, papery wrapper skins. These onions store well and are endlessly versatile for salads, sautés, stews, soups, and casseroles.

Details

Cold Winters: Feb – April 
Mild Winters: Jan – Apr, Sept – Oct 
Sun/Shade: Full Sun
Sow Seeds: 1 inch apart, 1/4 inch deep 
Days To Germinate: 10 – 14 days 
Days To Harvest: 85 – 105 days 

FOR BEST RESULTS
Sow seeds in early spring as soon as soil can be worked; in mild winter areas, seeds can also be sown in fall to overwinter for a head start in spring growth. To Start Early Indoors: Sow 1 in. apart in a container of seed starting mix and cover 1/4 in. deep. Provide a strong light source until seedlings are 2 to 3 in. tall. Transplant 4 in. apart, burying crowns 1 in. deep. To Start Outdoors: Sow seeds in well-worked, fertile soil in full sun. Space 1 in. apart in rows 8 in. apart. Cover 1/4 in. deep, firm soil well over seeds, and keep evenly moist. Thin seedlings gradually to a final 4 in. spacing, using the tasty thinnings.

GROWING NOTES
Before planting, thoroughly work compost or well-aged manure and bonemeal into the soil. Keep onions well weeded and mulch plants once soil warms up to conserve moisture. Feed onions lightly with an all-purpose fertilizer several times during the growing season.

HARVEST AND USE
Harvest midsummer when bulbs are sized up and about half the onion tops are bent over. Stop watering and bend the rest of the tops down. After another 7 to 10 days or when tops are dry, pull the bulbs. If possible, let the onions dry in the sun for 5 to 7 days. Store bulbs in a cool, airy place.
