Here’s everything you need to know about when to plant onions zone 7, including the best times of year, how to make sure you get a good crop, and how to avoid common problems.
Onion Set Planting Guide.
The best planting time for onions is in the fall. Onions can be planted in the spring, but the yield will be lower than if they were planted in the fall. They can also be planted in the summer, but again this will result in a lower yield compared to planting them in the fall.
Planting Onions in the Fall.
Planting onions in the fall is a great option for avid gardeners who want to have onions all winter. The process of planting bulbs in late fall or early winter helps them grow through their dormancy period and bloom earlier than they otherwise would. This allows your garden to provide food year round, rather than just during the summer months.
The first step of this process is choosing which kind of onion you want to plant; there are many varieties that will work well with this method, but it’s important to remember that some varieties won’t store well once harvested, so choose ones that will be suitably sweet when harvested. In addition, if possible try not to use those with thick necks; these tend not have as much flavor as other types because they don’t get enough sunlight through their underground growth period which makes them more susceptible to disease problems later on down the road (which could ruin any potential crop). Once these decisions have been made then all that remains before starting your fall planting season is preparing your soil and deciding where each bulb should go!
If done correctly then by late autumn most types should begin showing signs of life again despite being dormant since early summertime last year–which means lots more delicious goodness coming soon!
Onions are easy to grow from seed. They grow best in full sun, but will tolerate partial shade. A well-drained sandy soil is ideal for onions, but they will also do well in heavier soils as well. They should be planted in early spring when the soil temperature reaches 45 F degrees or higher. It takes about eight weeks for these seeds to germinate and another two months before you can harvest your first crop of green onions! We recommend starting your seeds indoors 6-8 weeks before transplanting them into their permanent location outside once the chance of frost has passed and daytime temperatures are above 75 F degrees during the day and 60 at night. Keep sowing more seeds every 2-3 weeks until early July or so if you want an extended season.”
Thin out your onion seedlings.
Once your seedlings have reached about 2 or 3 inches tall, thin them by snipping off some of the seedlings that are too close together. This prevents onions from forming a tight cluster and allows them to grow larger. For example, you should be able to fit two fingers between each onion plant in a row when they’re mature.
Leave your rows at least eight inches apart (and 24 inches apart if you’re growing sweet onions).
Sow your onions directly into the garden a few weeks before the last frost date.
Planting onion seeds directly into the garden is easy and inexpensive. You can also plant onion seed in the fall, but it is better to plant them in the spring for a better bulb yield. Onion plants are perennials that grow back year after year if you leave them undisturbed and take good care of them. The only time you need to harvest your onions will be when you want to use them or sell them at the farmers’ market or grocery store!
Transplant onions to the garden a few weeks after the last frost date.
Planting onions from seed is an easy way to get a head start on your garden. To plant onion seeds, simply sprinkle them evenly over the soil and cover with soil. Do not cover the seeds with more than 1/4″ of soil as they need light to germinate. If you’re planting onion seeds in a container or raised bed, be sure to give them plenty of room so that they have room to grow before being transplanted into rows or borders.
For those who don’t want to wait for onions from seedlings and would rather buy sets instead, here’s how:
Select bulbs that are firm and plump but not soft or wrinkled; avoid any bulbs whose outer skin has split open at all—this indicates that the bulb may be too old or damaged for good results;
Separate each bulb into individual cloves by twisting apart its neck (where it meets its stem);
After separating the cloves, soak them overnight before planting—you can speed up this process by placing them in warm water right away instead;
Plant at least 4 inches deep with pointed end up;
Common Causes of Onion Growing Problems.
To as great a degree as possible, you want to avoid having your onions fail to thrive. There are several common causes of onion growing problems that can be avoided or at least minimized with the right precautions. These include:
Pests and diseases
Inadequate sunlight (or too much sunlight)
In addition, there are two other issues that are less often considered but can cause serious problems for your plants: planting time and soil type/composition. If you choose to plant your onions in an area where they have not previously grown before, even if it is within their zone range, this can lead to unexpected results and is best avoided by starting with seeds if necessary instead of direct planting (that said, many people do this successfully). Additionally, some soils may hold more water than others; while this may seem like a good thing because it means less work for you during dry seasons when rainfall is sparsely spread out over several weeks instead of hitting hard all at once like hail does on hot summer days when temperatures rise above 80 degrees Fahrenheit (27 Celsius).
In addition to these preventive measures, you can also use companion planting to help deter pests and diseases. Companion planting is a method of growing plants that are mutually beneficial (or non-harmful) to each other. For example, carrots planted near onions help deter carrot fly. Some popular companion plantings include:
Carrots and beans
Cucumbers and radishes
Potatoes and tomatoes

Onion planting season is between April and June.
Onion seeds must be planted about 1/4 inch deep in the ground and spaced about 2 inches apart from each other.
Onions can grow as tall as 8 inches, so make sure that your plants have enough space around them so they do not shade their own seedlings or leaves.
With that, you should be well on your way to planting onions in zone 7!
