Planting onions is a rewarding and straightforward gardening activity.
- Choose the appropriate onion type for your region.
- Plant onion bulbs at a depth of one to two inches.
- Space the onion bulbs five to six inches apart.
- Water the onions after planting and provide regular moisture.
- Fertilize with nitrogen for larger bulbs but stop once bulbing begins.
To successfully plant onions in your garden, first, determine if you need short-day or long-day onions based on your local climate and daylight hours. Next, plant the onion bulbs at a depth of one to two inches in well-prepared soil that has been enriched with organic matter. Ensure the bulbs are spaced five to six inches apart to allow for growth and air circulation, which prevents disease.
After planting, water the onions immediately to help establish roots. Onions need about an inch of water per week, so make sure to maintain consistent moisture, especially during dry periods. This practice encourages strong and healthy growth. Provide the onions with regular feedings of nitrogen-rich fertilizer to support their development. However, be ready to stop fertilizing once the onions start forming bulbs, as this could otherwise inhibit their growth.
Remember, growing onions is fast, easy on the wallet, and a joy when harvest time comes around. With just a little tender loving care, you’ll enjoy the fruits of your labor in delicious meals and preserve them through quick and simple pickling recipes.
Onions are a great addition to home gardens or raised beds. They take up very little space, and they are easier to grow than you think. However, it’s important to know how deep to plant onions to ensure that you get the best onion crop at the end of the growing season.

How I Plant Onions

Onion bulbs or sets are small onions grown from seed the previous year. They are harvested as immature bulbs instead of being allowed to mature, and they are easy to find in mesh bags at your local garden centers. Here is how deep to plant onions bulbs when starting a new garden.
Start by sorting through the large and small bulbs. Large bulbs are ideal for growing green onions, and bulbs smaller than a dime are perfect for growing bulb onions. Plant the onion bulbs an inch to two inches deep in garden soil and space them five to six inches apart with rows twelve to fifteen inches apart.
If you live in an appropriate climate with a mild winter, plant short-day onions in October or November for a June harvest and long-day onions in the early spring for a late summer crop.
How Deep I Plant Onions from Seed
Unlike onion bulbs or sets, onion seeds are bulbs that have not grown yet, and sowing them produces onion seedlings for transplanting during the current growing season. Learn how deep to plant onions from seed and how far to space them for optimal growth.
Before the last frost in early spring, fill a seed starting tray with pre-moistened potting soil and sprinkle onion seeds evenly over the top. Cover them with an eighth of an inch of soil. Press the dirt down lightly and keep the tray in a warm area where the temperature is around 70 to 75°F to encourage germination.
When you’re ready to transplant the seedlings in the garden, harden them off, gently remove them from the container, and transplant them three to four inches apart in a prepared garden setting.
How I Plant Onion Bulbs
How do you plant onion bulbs? The quick and easy way to grow onions is from bulbs since seeds take longer to grow. Discover how to plant onion bulbs, the best way to plant onion sets, give your plants care as they grow, and when the onions are ready for harvesting.
Pick a full sun area for your garden and prepare it with organic matter before planting. In early spring or fall, depending on the onion type and the best time to plant onions in your zone, plant the onion bulbs with the recommended onion spacing and depth, and water them right after planting.
Fertilize the onions every few weeks with nitrogen to promote large bulbs. However, stop feeding the plants once the bulbing process begins. After you stop fertilizing, mulch them with a half-inch layer of straw to retain moisture and prevent weeds.
Ideal green onion growing conditions yield tastier onions. Water your onions as needed during dry spells to ensure they receive about an inch of water each week to prevent bolting and flower stalks.
Thrips and onion maggots are common pests of onions. There is no difference between yellow and white onions and other types regarding these bugs. Thrips are tiny insects as fat as a sewing needle and easy to eliminate with insecticidal soap, while fine mesh netting over your plants keeps onion maggots away.

Using My Fresh Garden Onions to Make Pickles
Making pickles is an excellent way to use garden onions before they go bad. The pickling process helps preserve the onions, and the result is a unique and tasty condiment for adding to burgers and hot dogs. This recipe can use all types of onions and uses vinegar and honey for a tasty combination.

Let them cool, put the lid in place, and keep the quick-pickled onions in the fridge for up to two weeks.
