Preparing for Planting
Getting ready to plant onions involves a few key tasks. You need to choose the right time, select suitable onion varieties, and prepare your soil. Each step plays an important role in growing healthy onions.
Choosing the Right Time
Timing is crucial for planting onions. The best time depends on your location and the type of onion. For example, long-day onions grow well in northern areas. You want to plant them in early spring when the soil is workable.
If you live in southern regions, you can choose intermediate varieties like Yellow Granex or White Bermuda. These onions do better with shorter days. Check local planting calendars to find the exact dates for your area.

Selecting Onion Varieties
Choosing the correct onion variety can make a big difference. Long-day onions, like the popular Candy, need around 14-16 hours of daylight. These are great for northern climates.
For those in warmer areas, select shorter-day onions such as Yellow Granex or White Bermuda. Intermediate varieties also work well when day length varies. Think about what you like to eat and how your local climate affects growth.
Soil Preparation and Fertilization
Healthy soil is essential for growing onions. Start by testing your soil’s pH level. Ideally, it should be between 6.0 and 7.0 to support onion growth.
Add organic matter, such as compost or well-rotted manure, to improve soil structure. This helps clay soil by creating better drainage and aeration. Before planting, mix in an organic fertilizer that is rich in nitrogen. This will feed your onions as they grow.
Prepare your planting area by removing weeds and debris. A clean bed will help prevent diseases. Loosen the soil and level it out for uniform growth. Your onions will thrive with the right preparation.

Planting and Caring for Onions
To grow onions successfully, you need to know how to sow seeds or transplant seedlings. You also have to consider proper watering and air circulation. Let’s look at these key steps closely.
Sowing and Transplanting
When starting from seeds, sow your onion seeds indoors about 8-10 weeks before the last frost date. Use seed trays and a light potting mix for best results.
Keep the soil moist to help with germination. Once the seedlings grow to about 4-6 inches tall, they can be transplanted outside. Make sure the weather is warm enough and transplant on a cloudy day, if possible, to reduce stress on the plants.
If you choose to plant onion bulbs instead, look for healthy, firm bulbs. Space them about 4 inches apart in rows. This gives them enough room to grow and develop properly.
Watering and Air Circulation
Water your onions regularly, especially during dry spells. The soil should stay moist but not waterlogged. A good rule is to water about 1 inch per week.
Good air circulation is important to prevent diseases like onion rot. Space your plants adequately to allow for airflow. If you are growing them in a greenhouse, open vents when temperatures rise. This keeps the environment healthy for your onions.
Managing Bulbing and Harvesting
As the onions grow, watch for signs of bulbing, which usually starts in late spring. When the onion tops start to fall over, it’s a sign that they are ready for harvest.
Gently lift the bulbs with a garden fork, being careful not to damage them. After harvesting, let the bulbs dry in a warm, airy place for several days. Once dried, you can store them in a cool, dark space.
Remember to check regularly for pests or diseases, as they can affect growth. Keeping your onions healthy leads to better yields.
