    Choose Bulb or Bunching Onions

    • Yellow bulb selections: Explore Texas 1015Y, Spanish Sweet Yellow, Texas Grano Early and Walla Walla. Check each listing and regional guidance for its day-length adaptation and planting window.
    • Red bulb selections: Compare Red Burgundy, Red Creole and Red Grano for flavor, maturity and kitchen use.
    • Crystal White Wax: A white onion choice for suitable pickling preparations and other meals.
    • Bunching onions: Crimson Forest and Long White offer a different harvest focus from full-sized bulb onions. Follow their own spacing and harvest instructions.

    Match Onion Day Length to Your Region

    Bulb onions respond to seasonal day length, not simply the hours of direct sun in a bed. Short-, intermediate- and long-day types have different bulbing requirements, so variety selection and timely planting matter. This collection should not be assumed to contain every day-length type. Bunching onions are grown primarily for tender green tops and bases rather than a large storage bulb.

    Planting Tips for Success

    • Plan your starting method: Follow each variety's guidance for direct sowing or starting seedlings and transplanting.
    • Allow establishment time: Bulb onions need suitable early growth before seasonal conditions trigger bulbing. Late planting can limit size.
    • Choose full sun: Prepare fertile, well-drained soil and use spacing appropriate to the intended harvest.
    • Follow depth instructions: Avoid deeply burying developing bulb onions when transplanting.
    • Water consistently: Maintain even moisture during establishment and growth without saturating the soil.
    • Weed gently: Onions have shallow roots and compete poorly with weeds. Cultivate carefully.
    • Feed thoughtfully: Follow soil-test recommendations and crop-stage guidance rather than heavy fertilizer feeding throughout the season.

    Harvest and Store for Your Intended Use

    Harvest bunching onions at the tender stage recommended for the variety. For mature bulb onions, watch for natural top fall and other variety-specific maturity signs. Lift carefully and cure storage-suitable bulbs in a dry, sheltered, well-ventilated place. Use fresh-use onions and damaged bulbs promptly. Keeping quality varies by variety, harvest condition and storage care; do not assume sweet onions will keep as long as storage types.

    Cooking Ideas for Your Harvest

    • Fresh: Slice suitable bulb onions for salads and sandwiches, or chop bunching onions for toppings.
    • Everyday cooking: Sauté onions as a foundation for soups, sauces and skillet meals.
    • Roasted and caramelized: Develop savory sweetness through roasting or slow cooking.
    • Pickles: Use a reliable refrigerator-pickle recipe or a tested preservation recipe for shelf-stable canning.

    Kitchen suggestions apply to harvested onions, not planting seeds. These products are seeds, not live onion plants, bulb sets or harvested produce.
