Yellow Onion Seeds

Yellow onions are a staple in cooking, known for their robust flavor and versatility. They have a slightly sweet and tangy taste when raw, which becomes milder and sweeter when cooked. Yellow onions are excellent for caramelizing due to their natural sugars, adding depth and richness to dishes like soups, stews, and sauces. They are also commonly used in sautés, stir-fries, and as a base for many recipes.

Growing Instructions

Starting your seeds

You can start Yellow Onion seeds indoors using a heat mat to encourage germination. Once the seedlings sprout and grow a few sets of leaves, move them outdoors. Keep the soil moist and provide 6–8 hours of sunlight daily. When direct sowing Yellow Onion seeds, plant them about 1/4 inch deep in well-drained soil, spacing them 4–6 inches apart in rows 12–18 inches apart to give them enough room to grow.

Harvesting your seeds

To harvest onions, wait until the tops have fallen over and turned brown. Gently lift the onions from the soil, and allow them to cure in a dry, shaded area for a couple of weeks. Once the outer layers are dry and papery, trim the tops and roots, and store the onions in a cool, dry place.
