Onions are a staple in many kitchens, and growing your own onions can be a rewarding experience. However, growing onions in Florida can be a challenge due to the state's hot and humid climate. In this article, we will provide a guide on how to grow onions in Florida successfully.
Onion Bulb Development
Onions grow from bulbs, which are essentially modified stems. The bulb provides the nutrients needed for the plant to grow and produce leaves, stems, and flowers. When planting onions, it is essential to choose the right type of bulb.
There are two main types of onion bulbs:
- Seeds: Onion seeds take longer to mature, but they produce larger onions. They are also cheaper than sets.
- Sets: Onion sets are small bulbs that have already begun to grow. They are faster to mature than seeds, but they produce smaller onions.

Growing Onions from Seed
Growing onions from seed is a cost-effective way to produce large onions. However, it takes longer than growing onions from sets. Here are the steps to grow onions from seed:
- Start the seeds indoors: In Florida, it is best to start the seeds indoors in late fall or early winter. Fill a seed tray with potting soil and plant the seeds about ¼ inch deep. Keep the soil moist and place the tray in a warm area with plenty of sunlight.
- Transplant the seedlings: After a few weeks, the seedlings will emerge, and you can transplant them into larger containers or directly into the ground. If transplanting directly into the ground, make sure the soil is well-draining and has plenty of organic matter.
- Plant the seedlings: When planting onion seedlings, make sure they are at least 1 inch apart. Plant them about 1 inch deep, with the top of the bulb just above the soil surface. Water the seedlings regularly, but do not overwater them.
Planting Onion Sets
If you want to grow onions quickly, you can plant sets. Onion sets are small bulbs that have already begun to grow, so they mature faster than seeds. Here are the steps to plant onion sets:
- Choose the right time: Onion sets can be planted in Florida in the fall or early winter.
- Prepare the soil: Before planting, prepare the soil by adding plenty of organic matter. The soil should be well-draining, and the pH should be between 6.0 and 7.5.
- Plant the sets: Plant the sets about 1 inch deep, with the pointed end facing up. Space them about 4 inches apart. Water the sets well after planting.
- Mulch the onions: Mulch around the onions with organic material such as straw, grass clippings, or leaves. This helps to retain moisture and suppress weed growth.

Full Sun and 1 Inch Deep
Onions need full sun to grow properly. Choose a spot in your garden that gets at least 6 hours of direct sunlight per day. Onions also need to be planted about 1 inch deep, with the top of the bulb just above the soil surface. If planted too deep, the onions may not develop properly.
Green Onions
Green onions are a popular addition to salads and other dishes. They are also easier to grow than regular onions. To grow green onions:
- Plant the seeds: Plant onion seeds about ¼ inch deep in well-draining soil. Water the soil regularly to keep it moist.
- Thin the seedlings: When the seedlings are about 4 inches tall, thin them out so that they are about 2 inches apart.
- Harvest the green onions: Harvest the green onions when they are about 6-8 inches tall. Cut them off at the base of the plant, leaving about an inch of the stem in the ground. The green onions will regrow, and you can continue to harvest them until they start to produce bulbs.
Onions in Florida
Growing onions in Florida can be a challenge due to the state's hot and humid climate. Here are some tips to help you grow onions successfully in Florida:
- Choose the right variety: Some onion varieties are better suited for Florida's climate than others. Look for varieties that are heat-tolerant and have a short growing season.
- Plant at the right time: Onions should be planted in Florida in the fall or early winter. This allows them to mature before the hot summer months.
- Water regularly: Onions need regular watering to develop properly. However, be careful not to overwater them, as this can lead to rot.
- Fertilize: Onions need plenty of nutrients to grow properly. Use a balanced fertilizer every 4-6 weeks to ensure they are getting the nutrients they need.
Conclusion
Growing onions in Florida can be challenging, but with the right knowledge and techniques, it is possible to produce a bountiful crop. Whether you choose to grow onions from seed or sets, make sure to choose the right variety for Florida's climate, plant at the right time, and provide plenty of water and nutrients. With a little care and attention, you can enjoy the delicious taste of fresh, home-grown onions all year round.
