Growing onions in 5 gallon buckets is a popular option for gardeners who lack space or have poor soil quality in their yards. It is a convenient and space-saving method of growing onions, especially for those who live in apartments or have limited yard space. Using 5 gallon buckets to grow onions can be a great way to get fresh, homegrown onions without the need for a large garden plot.
To grow onions in 5 gallon buckets, you will need to make sure that the soil is well-draining and that the bucket has adequate drainage holes. Onions require a lot of moisture, so it is important to keep the soil consistently moist but not waterlogged. You can grow up to 6-8 onions in a 5 gallon bucket, but using a larger container will allow you to grow more. With the right conditions, you can grow onions in 5 gallon buckets just as successfully as you would in a traditional garden bed.
Choosing the Right Bucket – Can You Grow Onions in 5 Gallon Buckets?
When it comes to growing onions in 5-gallon buckets, choosing the right bucket is crucial. In this section, I will discuss the two most important factors to consider when selecting a bucket: size and type, and drainage requirements.
Bucket Size and Type
The first thing to consider when selecting a bucket is its size. A 5-gallon bucket is the perfect size for growing onions. However, keep in mind that the bucket should be at least 10 inches deep to provide enough room for the onions and their roots to grow under the soil. Additionally, make sure to choose a bucket that is wide enough to accommodate the number of onions you want to grow.
The type of bucket you choose is also important. Food grade buckets are the best option for growing onions since they are made from high-density polyethylene (HDPE) and are safe for growing food. Avoid using buckets that were previously used to store chemicals or other non-food items.
Drainage Requirements
Proper drainage is essential for growing onions in buckets. Without adequate drainage, the soil can become waterlogged, which can lead to root rot and other problems. To ensure proper drainage, drill several drainage holes in the bottom of the bucket using a drill. Make sure to space the holes evenly to allow water to drain evenly.
In addition to drainage holes in the bottom of the bucket, you can also drill holes around the sides of the bucket. This will allow excess water to drain out of the bucket more easily. However, be careful not to drill too many holes, as this can cause the soil to dry out too quickly.
By choosing the right size and type of bucket and ensuring proper drainage, you can create the ideal growing environment for your onions.
Preparing the Soil
When it comes to growing onions in 5 gallon buckets, preparing the soil is crucial for a successful harvest. In this section, I will cover the soil composition, pH levels, and nutrients required for growing onions in a container.
Soil Composition – Can You Grow Onions in 5 Gallon Buckets?
The first step in preparing the soil is to choose the right potting soil. A good quality potting soil should be light, well-draining, and rich in organic matter. I recommend using a potting mix that contains peat moss, perlite, and vermiculite. These ingredients will provide good aeration, drainage, and moisture retention, which are essential for growing healthy onions.
It’s important to note that onions prefer a slightly acidic soil with a pH level between 6.0 and 6.5. If the soil is too alkaline, the onions may not grow properly. To adjust the pH level, you can add sulfur or aluminum sulfate to the soil.
pH Levels and Nutrients
Onions require a variety of nutrients to grow properly. A good potting soil will contain some nutrients, but you may need to add more depending on the quality of the soil. I recommend adding compost to the soil to provide additional nutrients. Compost is rich in organic matter and contains a variety of nutrients that are essential for plant growth.
In addition to compost, you can also add a slow-release fertilizer to the soil. A balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium is ideal for growing onions. Be sure to follow the instructions on the fertilizer package and don’t over-fertilize, as this can damage the plants.
Preparing the soil is an important step in growing onions in 5 gallon buckets. By choosing the right potting soil, adjusting the pH level, and adding compost and fertilizer, you can provide your onions with the nutrients they need to grow healthy and strong.
Selecting Onion Varieties – Can You Grow Onions in 5 Gallon Buckets?
Growing onions in a 5-gallon bucket is possible, but it is important to choose the right type of onion variety to ensure a successful harvest. When selecting onion varieties, there are a few key factors to consider.
Long-Day vs Short-Day Onions – Can You Grow Onions in 5 Gallon Buckets?
Onions are classified as either long-day or short-day varieties based on the number of daylight hours required for bulb formation. Long-day onions require 14-16 hours of daylight to form bulbs, while short-day onions require 10-12 hours of daylight.
For those living in the northern hemisphere, it is best to choose long-day onion varieties. These onions require a longer period of daylight to form bulbs, which is ideal for the longer days of summer. On the other hand, short-day onion varieties are more suitable for those living in the southern hemisphere, where daylight hours are shorter.
Seed, Sets, or Seedlings
When it comes to planting onions, there are three main options: seeds, sets, or seedlings.
Seeds are the most economical option, but they require a longer growing period. Onion sets are small, immature bulbs that are easy to plant and grow quickly. Seedlings are the most convenient option, but they can be more expensive than seeds or sets.
When growing onions in a 5-gallon bucket, it is recommended to use either onion sets or seedlings. These options are better suited for container gardening and will produce a higher yield in a smaller space.
Overall, selecting the right onion variety is crucial for a successful harvest. By considering factors such as long-day vs short-day onions and the type of planting material, you can ensure that your onions thrive in a 5-gallon bucket.

- Avoid planting onions in the same location year after year to prevent a buildup of soil-borne pathogens.
By following these tips, you can help ensure that your onions stay healthy and productive, even in a small space like a 5-gallon bucket.
Harvesting and Storing Onions – Can You Grow Onions in 5 Gallon Buckets?
As the onion bulbs mature, they develop a papery outer layer and the tops start to yellow and fall over. This indicates that the onions are ready to be harvested. However, it is important to harvest onions at the right time to ensure that they store well.
When to Harvest – Can You Grow Onions in 5 Gallon Buckets?
Onions should be harvested when the tops have fallen over and started to dry out. This usually happens in late summer or early fall, depending on when you planted them. To check if the onions are ready, gently push the soil away from the bulb and check the size of the bulb. If the bulb is the size of a golf ball or larger, it is ready to be harvested.
It is important to harvest onions when the weather is dry. Wet weather can cause the onions to rot in storage. If the weather is wet when the onions are ready to be harvested, leave them in the ground for a few more days to dry out.
Curing and Storage
After harvesting, the onions need to be cured before they can be stored. Curing is the process of drying the onions in a warm, dry place for several weeks to toughen the outer layer and extend their storage life.
To cure onions, spread them out in a single layer in a warm, dry, well-ventilated area such as a garage or shed. Avoid direct sunlight as it can cause the onions to sunburn. Leave the onions to cure for 2-3 weeks, turning them occasionally to ensure even drying.
Once the onions are cured, cut off the tops and roots and brush off any loose dirt. Store the onions in a cool, dry, well-ventilated area such as a pantry or cellar. Do not store onions near potatoes as they release moisture and gases that can cause onions to spoil. Onions can be stored for several months if they are properly cured and stored.
Harvesting and storing onions is a simple process that requires a bit of patience and attention to detail. By following these simple steps, you can ensure that your onions are ready to use whenever you need them.
Advantages of Bucket Gardening – Can You Grow Onions in 5 Gallon Buckets?
As an avid gardener with limited space, I have found that bucket gardening is a great solution for growing plants in a small area. There are several advantages to using buckets for gardening, which I will discuss below.
Space Efficiency
One of the biggest advantages of bucket gardening is that it is space-efficient. If you have a small patio or backyard, you can still grow plants by using containers. Buckets are an ideal container for gardening because they are deep enough to accommodate the root system of many plants, yet they are also narrow enough to fit in a small space. You can stack buckets on top of each other to create a vertical garden, which is perfect for small spaces.
Mobility and Control – Can You Grow Onions in 5 Gallon Buckets?
Another advantage of bucket gardening is that it allows for mobility and control. Buckets are easy to move around, which means you can position them in the best spot for your plants. If you have a plant that requires more or less sunlight, you can easily move the bucket to a different location. Additionally, buckets allow for better control over the soil and water conditions. You can easily monitor the moisture level of the soil and adjust it as needed. Buckets also prevent soil erosion and weed growth.
Bucket gardening is a great solution for those with limited space who still want to enjoy the benefits of gardening. Buckets are space-efficient, mobile, and provide better control over soil and water conditions. Whether you have a small patio or a large backyard, bucket gardening is a great way to grow plants and vegetables.
Companion Planting and Crop Rotation
Compatible Plants – Can You Grow Onions in 5 Gallon Buckets?
When growing onions in 5-gallon buckets, companion planting can be an effective way to improve the health and yield of your crop. Companion planting involves growing two or more plants together that benefit each other in some way. Some plants have natural abilities to repel pests or attract beneficial insects, while others can improve soil health and nutrient levels.
Carrots, for example, are a great companion plant for onions. Onions and carrots have different root depths, so they don’t compete for nutrients in the soil. Carrots can also help to improve soil structure, making it easier for onions to grow and absorb nutrients. Additionally, the strong smell of onions can help to repel carrot flies, which can damage carrot crops.
Other compatible plants for onions include potatoes, beans, tomatoes, cucumbers, eggplants, garlic, peas, peppers, and radishes. These plants can help to improve soil health, repel pests, and attract beneficial insects.
Rotation Benefits
Crop rotation is another important practice to consider when growing onions in 5-gallon buckets. Crop rotation involves planting different crops in the same area each year to help prevent soil-borne diseases and pests from building up. It can also help to improve soil health and nutrient levels.
When rotating crops, it’s important to avoid planting onions or other alliums in the same area for at least three years. This is because alliums can attract soil-borne pests and diseases that can damage onion crops. Instead, consider planting crops like tomatoes, peppers, or beans in the same area to help break up the pest and disease cycle.
In addition to crop rotation, it’s important to practice good sanitation when growing onions in 5-gallon buckets. This includes removing any dead plant material and avoiding planting onions or other alliums near each other. By following these practices, you can help to ensure a healthy and productive onion crop.
