Texas Early Grano

Family: Amaryllidaceae Vegetable

Sun-warmed and sweet from the start, Texas Early Grano forms tender, golden bulbs with a softly layered bite and a clean, aromatic finish.

Expect a mild, juicy sweetness that shines fresh, while its crisp texture holds beautifully for quick sautés and caramelizing-style browning in the pan. A warm-season favorite for gardeners who want early harvest satisfaction—90 days to maturity with bulbs that reward attentive thinning and steady growth.

Culinary Notes

Chef's Note

Texas Early Grano gives you sweet onion flavor without the aggressive raw bite—its crisp layers stay intact under fast heat. It browns quickly in a pan, so it’s ideal when you want that jammy edge without waiting for slow, deep caramelization.

Best Uses

thin slicing for quick fresh salads where it stays crisp
hot skillet sauté with butter to get glossy, golden edges without harshness
shallow caramelization for jammy, spoonable onions
pizza/tart topping where it cooks fast and turns tender

Frequently Asked Questions

What pest or disease commonly affects Allium cepa (Texas Early Grano) and how can I control it?

Onions (Allium cepa) are especially prone to purple blotch (Alternaria porri) and downy mildew when leaves stay wet. Improve airflow by spacing plants, water at the soil line (not over the foliage), and remove heavily spotted leaves early to slow spread. If the problem persists, use a labeled sulfur or copper fungicide at the first signs and repeat according to label directions.

How often should I water Texas Early Grano during the main bulb-growing phase?

During bulb swelling (roughly mid-season through the last several weeks), keep the soil consistently evenly moist but not soggy—about 1 inch (2.5 cm) of water per week split into 1–2 deep irrigations. If the soil dries out completely, bulbs can stall and split; if it stays wet, disease risk rises. Check by feel 2–3 inches down—water when it’s dry at that depth, and taper once tops begin to yellow.

How do I know when Texas Early Grano onions are ready to harvest?

Harvest when most of the tops (typically about 50–70%) have fallen over and the necks start to dry down, usually around 90 days. Gently lift one bulb to confirm the skin is tight and papery and the bulb size feels fully formed. Stop watering 1–2 weeks before harvest so the necks dry for better curing and storage.
