About Texas Early Grano Onion: Texas Early Grano onions come from the horticultural researches of Texas Agricultural Experiment Station of Texas A&M University. In their search for a high yielding, sweet onion that produced an early crop, they selected a variety from Spain and continued to improve it over a period of several years. In 1944, Texas A&M University released this new variety of onion as Texas Early Grano.
Harvesting Texas Early Grano Onion: When the tops of the onions turn yellow or flop over, they have matured and are ready to be harvested. Pull them from the earth, brush off the dirt, and leave them to cure in the sun for a week. If the weather turns rainy, bring them inside to cure in a dry, well ventilated place. When the skin dries, cut the tops down to 1" and trim the roots. Store in a cool, dry place. Texas Early Grano onions do not store well for long periods of time.
Texas Early Grano Onion Germination: Since onions take a few months to mature from seed, gardeners with a short growing season may want to start their seed indoors. Plant the seeds 1/2" deep in a flat 2-3 months before the last frost date; keep the soil moist and at room temperature. When the tops begin to flop over, cut them off to 3" to focus the growing on the roots. Four weeks before the last frost or when the soil reaches at least 50 degrees F, transplant the seedlings 6" apart in rows 12" apart. For direct sowing, sow three seeds per inch 1/2" deep in light, rich soil and full sun.
Thin the seedlings 2-6" apart, depending on the desired size. Thinned onions can be transplanted or used for fresh eating. For companion planting benefits, plant onions with members of the cabbage family, lettuce, or tomatoes; avoid planting onions with peas or beans. In areas with warmer winters, onions may be grown as a fall or winter crop. Growing Texas Early Grano Onion Seeds: Onions need moisture especially in their first several weeks of growth, and they cannot fight against weeds; mulching onions can help with both moisture and weed control. Texas Early Grano onions are quite disease resistant.
