10 Onion Growing Problems and How to Prevent Them

Do you enjoy cooking with onions? You can cultivate your own and have a steady supply for several months. Onions can be refrigerated or dehydrated to extend their shelf life, or they can be stored fresh in bulbs. Onions, on the other hand, can be a bit difficult to cultivate because of their sensitivity to temperature fluctuations, which can impact the size of their bulbs. If you want to grow onions in your garden but have run into trouble, here are 10 onion growing issues and solutions.

Choosing the Wrong Onion Type

When it comes to producing onions, one of the most common mistakes people make is planting the wrong variety at the wrong area. Ordering onion sources online generally causes this issue. Depending on your planting needs, you can choose from three types of onions that are ready to go: short-day, long-day, or intermediate-day. The best sort to buy depends on where you live and what you plan to use it for, such as bulbs or toppers. If you wish to plant bulbs, make sure you pick one that is adapted to your geographic location’s climate. On the internet, there are charts that show the most suggested kinds for various locations.

Planting Onion Sets or Transplants without Knowing the Source

Onion transplants look like green onions with long stems and a tuft of roots at the bottom, whereas onion sets seem like miniature onion bulbs. If you don’t know what variety and where the onions came from, you’re likely to expect to harvest onion bulbs from sets and spring onions for transplanting. The type and placement of the onion sets or transplants that gardeners use can have a big impact on how well they do in the long term.

Even today, the weather has a significant impact on how well onions grow. To learn more about the types of sets or transplants to use in your location, visit your local university extension or join a local onion growing association. When planted in a different climate, onions utilized in other places may not produce the same results.

Choosing the Wrong Size of Sets and Transplants

Choosing the wrong size transplants or sets while planting onions is a common blunder. New gardeners frequently pick the largest plant in the group. There is a precise onion harvesting size that you should use if you want a specific result. The width of a pencil is a good guideline when choosing transplants to use. Choose large bulbs for green onions and medium ones for huge bulbs when putting together a pair.

Using Seeds to Grow Onions

Seeds can be difficult to grow before the frost season in areas with short day climates. Developing onions’ greens takes a long period since onions need time to obtain nutrients for growth. Folks with shorter days are more likely to plant their seeds too late. When dealing with this issue, it’s imperative that seeds are planted 10-12 weeks before the first frost.

Planting Transplants with the Wrong Depth and Distance

Planting transplants too deep or too near together is another common blunder. They should be planted at a depth of one inch or at a depth that allows them to stand on their own. The distance between the transplants should be 6-8 inches in order for the bulbs to grow huge. As a result, they have plenty of room in the soil to obtain the nutrients they need.

Feeding is insufficient

Growing onions are heavy feeders. They need huge amounts of nitrogen in the soil regularly to sustain good leaf growth. This can be done by synthetic nitrogen fertilizers. However, if you wish to avoid synthetic ones, there are also organic sources like Milorganite, Chicken manure, and Corn gluten meal.

Not using the Right Amount of Water

To grow properly, onions require a lot of water. If the weather isn’t cooperating, make sure to water them frequently to keep them from bolting. Avoid letting the onions become too wet, however. Soil should not retain water for an extended period of time, which is why drainage is required. Raised beds are an option if the soil contains a high amount of clay; otherwise, dig your onions into the ground.

Lacking Excessive exposure to the sun

Onions, although not being fruit-bearing plants, enjoy the light just as much as the rest of the plant kingdom. Ensure that other plants will not obstruct the sun during the onions’ growing phase if you plan to plant them next to them.

With Weeds All Around Me

Onions are heavy feeders, therefore they require as much soil nutrition as possible while they are growing. Weeds compete for nutrients with other plants. During the onion’s growth phase, be sure to eliminate any undesired plants that have sprouted near the onion bed.

Bolts’ Visual Aesthetic

To begin with, onions have bolts, which are white, teardrop-shaped structures found in the core of the stalks that will eventually become blossoms. They’re attractive, but the bulbs won’t grow as large and won’t be able to be utilized for cooking if you have them. Temperature changes are frequently to blame for these problems. After the spring rains and before the start of the summer months, you can start mulching around the onions to avoid this. You can also water the soil frequently when it gets hotter during the day to keep it cool.

Putting a Cover on Bare Bulb

There may be moments before harvest when the bulbs are visible above ground. Despite the fact that it may seem alluring to bury them in soil, as is done with potatoes, this is not recommended because it might lead to stem rot.

removing the leaves and stems

Some onion growers break the stems of their onions and set them on top of the soil, hoping this will encourage the bulb to grow larger. Others simply plant the onions whole. Onion nutrients comes from the stem, therefore cutting it off isn’t a good idea. They’ll require it until they reach their full adult size, though. These stems will naturally fall off once they’ve reached their full maturity.

These helpful hints can come in handy if you decide to create an onion garden. When onions are growing, they can display a wide range of characteristics, and one of these is where you live. For further information on which onions to utilize and other strategies you can employ when trying to grow these plants, you should speak with your local university garden extension office.
