Onions come in several different varieties, each suited to different growing conditions and tastes. Some common varieties of onion seeds include:

- Yellow onions: These are the most widely used onions and what most people think of as the traditional yellow onion. Varieties include Texas SuperSweet and Sweet Vidalia onions. Yellow onions have a mild flavor and store well.

- Red onions: Red onions have a sweet, mild flavor and add color and nutrition to dishes. Well-known varieties are Red Wing and Candy.

- White onions: White onions tend to be slightly stronger in flavor than yellow onions. Popular varieties are White Lisbon and White Sweet Spanish.

- Green (scallion) onions: Also known as spring onions or green onions, these varieties are harvested with both the green tops and white bulbs. Common types are Evergreen White and Welsh Onion.

Preparing the Soil for Onion Seeds

Onions grow best in loose, nutrient-rich soil with a neutral pH between 6.0 to 7.0. To prepare the soil:

- Remove any weeds and debris from the planting area.

- Till or fork the soil to loosen it and incorporate organic matter like compost or well-rotted manure. This will improve drainage and increase nutrients.

- Onion Seeds prefer soil with high phosphorus and potassium levels so you may want to add a balanced organic fertilizer or composted chicken manure.

- Rake the soil smooth and break up any clumps so individual seeds can be planted at a uniform depth.

Planting and Germinating Onion Seeds

Most onion varieties are planted as seeds four to six weeks before the last expected spring frost date. Here are tips for successful germination:

- Plant onion seeds 1/4 inch deep and 1/2 to 1 inch apart in rows 12 to 18 inches apart.

- Firm the soil gently over seeds with a rake or flat board to ensure good seed-soil contact.

- Keep the soil uniformly moist until seeds sprout, which usually takes 7-14 days. Do not let soil dry out.

- Once seedlings emerge, reduce watering but do not let soil completely dry out.

- Thin emerging seedlings to their final spacing as needed once they have two true leaves for best bulb development.
