Onion Seeds - All In One For Home Gardens
Quality Onion seeds for home gardens, raised beds, and edible garden plots.
Onion, commonly known as Bulb Onion, is a cool-season vegetable plant cultivated for its layered underground bulbs and upright hollow leaves. The plant develops slender green foliage that grows above the soil while the bulb gradually enlarges beneath the surface. Onions grow best in well-drained fertile soil with full sunlight and moderate temperatures. They are commonly planted in vegetable gardens and raised beds where consistent moisture and loose soil support uniform bulb development during the growing season.
