How Long Does It Take For Red Onions To Grow

In a friendly tone: I love onions. Not because they’re tasty, but because they’re the quintessential sign of fall. They make you feel like it’s cold outside and that pumpkin spice latte is just around the corner. That’s why I’m writing this blog post, to boost your feelings of fall nostalgia and remind you that it’s time to plant some tiny seeds in the ground. I’ve done this enough times in my life to know what works and what doesn’t, so here are my best tips for growing onions from seed to harvest. Because if there’s one thing I’ve learned from onions, it’s that there are no shortcuts when it comes to growing them from seed.

How long do onion seeds take to grow?

How long does it take for onion seeds to sprout?

Onion seeds can take up to 14 days to germinate. The time it takes for them to sprout depends on the temperature, as well as how old your onion seed is when you plant it. If you’re planning on growing onions from seed outdoors, it’s best not to plant them until after the last frost date in your region—about three months before your average first frost of the year.

How long does it take for onions to mature?

You may have heard that onions take a long time to grow. In fact, it is true. Onions can take anywhere from 80-120 days to reach maturity, depending how you plant them. If you plant them in the fall, they will likely take longer than if you plant them in the spring or winter because the soil isn’t warm enough for them to grow quickly.

If you do decide on planting your onions in the fall though, don’t worry too much—you won’t need to check on them every day like some other plants would require! Because onion bulbs are so hardy and sturdy (not unlike their namesake), they can also handle being left alone for several weeks at a time without rotting away before their time has come!

When do onions need to be harvested?

In order to harvest your onions, you must wait until they are mature. A mature onion will be dry and firm to the touch. If you squeeze one lightly, it should bounce back into its original shape without any effort. When you look at a bunch of mature onions, their color will be a deep, rich color that is slightly darker than when they were immature.

When harvesting your onions from the ground or from the plant (the latter being much easier), you want to make sure that there are no green leaves left on them at all. You can tell an onion if it’s ready for harvest by gently squeezing its base—if they’re ready then there’ll be no give whatsoever; if there’s still some give then leave them for another week or so before checking again as this means they’re not fully developed yet!

What are the best conditions for growing onions?

Most onions require a lot of sun, so if you live in an area with a short growing season, consider starting your onion plants indoors under artificial lights. If you don’t have the right conditions outside, grow them inside. Growing onions can also be done in large containers on patios or balconies.

Onions are fast-growing—they germinate quickly and produce bulbs quickly. They can suffer from root rot if they are planted too deep (roots should never be buried more than 2 inches deep). The best way to prevent this is by adding plenty of organic matter to the soil before planting; it will loosen the soil and make it less likely that roots will become waterlogged or unable to breathe properly.

Depending on the variety of onions you plant, onions may need between 80-120 frost-free days to grow.

Onions are a versatile vegetable that can be grown in many different climates and seasons. Onions have a long growing period, lasting from 60-90 days depending on the variety and time of year they’re planted. This means you can grow onions in the spring, summer or fall!

Onions are an excellent source of vitamin C, folate and potassium — all important nutrients for overall health. Onions are also used in many recipes for soups, stews, sauces and more!

There are a variety of factors that will determine how long it takes for onions to grow including the onion variety, the soil conditions and temperature. The most important thing to consider is the frost-free period so you can plan accordingly when starting your onions.
