Time & Duration

When to grow brussels sprouts from seed?

Since it will take you quite a long time to grow brussels sprouts, you should sow seeds early in the year in spring around two weeks before you expect the last spring frost of the season.

Alternatively, you could also start growing brussels sprouts in late summer to harvest them right before winter.

Do brussels sprouts grow year-round?

While you could grow brussels sprouts year-round, those plants will still require cool outdoor temperatures to grow well and this means that you should not grow brussels sprouts in summer but rather in spring and fall when temperatures are not too hot outdoors.

Do brussels sprouts grow fast?

It can take many months to grow brussels sprouts from seed.

Hence, it is not an optimal plant for impatient people and if you want to see results quickly, you should rather grow lettuce, spinach or carrots instead of growing brussels sprouts.

Prepare the soil!

How long does it take to grow brussels sprouts?

It will take you between 90 and 140 days to grow brussels sprouts from seed to harvest.

This also greatly depends on the climatic conditions you provide to your plants and also how well you care for them.

Also your level of experience in gardening plays a major role since the fewer mistakes you make, the faster you will be able to grow brussels sprouts at home.

Do brussels sprouts grow back every year?

As soon as you harvest brussels sprout plants, they will most likely not grow back.

Consequently, if you want to get brussels sprout yields for many years to come, you will have to plant new seeds for every growing season every year.

How long do brussels sprout plants live?

Once you harvest brussels sprout plants, you will usually also remove the plant material and the life of your plants will be over.

However, if you let brussels sprouts grow naturally without harvesting them, they can live for up to 8 months until the first strong winter frost hits and your plants decay.

How long does it take until brussels sprouts flower?

Brussels sprouts usually flower between one and two months after you’ve planted the seeds.

However, it can also take significantly longer if you don’t provide optimal growing conditions to your plants and you should therefore optimize those factors to grow sprouts as fast as possible.

Can you grow brussels sprouts in fall?

While the best time to grow brussels sprouts is in spring, you could also grow brussels sprouts in fall as long as you make sure that you wait until hot summer months are over but also plant brussels sprouts early enough so that they will mature before the first strong winter frost arrives.

Can you grow brussels sprouts in winter?

Starting to grow brussels sprouts in winter is not a good idea at all since you would have to do so indoors to protect brussels sprout plants from frost.

However, you would not be able to provide cool temperatures sprouts need to grow well indoors and this would greatly lower your yields.

Location & Climate

Will brussels sprouts grow in shade?

Even though brussels sprouts love cool weather, you should still not grow them in complete shade since your plants also need a certain level of sun exposure to grow well.

Hence, instead of growing sprouts in shade, make sure to grow them in a spot where they get at least a few hours of sunlight.

Will brussels sprouts grow in partial shade?

Partial shade is a great environment to grow brussels sprouts since you will be able to provide sufficient sunlight to your plants while you will still be able to protect your plants from excessive sun exposure, radiation and heat.

Do brussels sprouts grow best in full sun?

While brussels sprout plants like a certain level of sun, too much of it will be rather harmful to your plants.

Consequently, don’t grow brussels sprouts in full sun but rather choose a site where your plants get a decent mix of sun and shade.

Will brussels sprouts tolerate frost?

Even though brussels sprouts like cool weather, they are still not resistant to frost.

Thus, make sure to wait with growing brussels sprout seedlings outdoors until you don’t expect frost anymore so that your plants will not decay.

Do you have to protect brussels sprouts from the sun?

While there is no need to actively protect brussels sprouts from the sun, you should rather choose a partially shady spot for your plants so that they get a healthy mix of sun and shade and are protected from excessive sun exposure in a completely natural manner.

How much space do you need to grow brussels sprouts?

Brussels sprout plants can grow quite big both in the vertical as well as in the horizontal and this means that you should provide lots of space to your plants.

Hence, make sure that you plan at least 4 square feet of space for each plant so that brussels sprouts don’t have to compete for nutrients with each other.

Will brussels sprouts grow indoors?

While you could try growing sprouts indoors, you would most likely not be successful since brussels sprouts need the cold to grow well and it would just be too hot indoors.

Consequently, instead of growing sprouts indoors, you should rather grow them outdoors.

Can you grow brussels sprouts without a garden or balcony?

If you can’t grow brussels sprouts outdoors since you don’t have a garden or a balcony, your only option to grow sprouts at home would be to do it indoors.

However, you would run into many problems and I therefore suggest you wait with growing sprouts until you move to a home where you will have access to a balcony or a garden to provide decent growing conditions to your plants.

Can you grow brussels sprouts in small flats?

Since brussels sprout plants can get quite big and also like the cold, you should not grow sprouts in small flats since those plants would just take away too much space from you.

Instead, wait with growing sprouts at home until you move to a bigger place.

Can you grow brussels sprouts in an aquarium?

While you could try growing brussels sprouts in an aquarium that you fill with potting soil, you would still not be able to make sure that water will run off properly and waterlogging would likely become an issue.

In turn, the roots of your plants may start to rot and you should therefore not grow brussels sprouts in aquariums but rather use conventional flower pots instead.

Can you grow brussels sprouts in a terrarium?

Growing sprouts in a terrarium is not a good idea since waterlogging may become an issue and once you fill a terrarium with potting soil, it also becomes quite heavy and inflexible to move.

Hence, don’t grow sprouts in a terrarium but rather use more conventional methods instead.

Growing brussels sprouts in buckets is perfectly fine as long as you make sure that water will be able to run off properly and also that you use big buckets so that your plants get sufficient nutrients to grow fast and to develop healthy crops.

Can you grow brussels sprouts in bags?

You may also want to try growing brussels sprouts in bags.

However, from my experience, this only works if you use really big fabric bags since they are much stabler compared to plastic bags and water will also be able to run off much better.

Can you grow brussels sprouts in hanging baskets?

Since brussels sprout crops can get quite heavy, it is not a good idea to grow sprouts in hanging baskets unless you make sure that your baskets have a really solid foundation and will not fall down during your gardening project.

Can you grow brussels sprouts in rainy climatic zones?

Since brussels sprouts grow well with cool temperatures, you will be perfectly fine to grow them in rainy climatic zones as long as it is not too hot outdoors.

Also make sure to choose a sunny spot around your home to utilize every precious hour of sunlight your plants can get.

Can you grow brussels sprouts in tropical climatic zones?

Since brussels sprouts are cool-weather plants, you should never try growing them in the tropics since temperatures outdoors would just be far too hot and humid and you should rather grow tomatoes and other vegetables that are much more used to the heat.

Can you grow brussels sprouts in regions with permafrost?

While brussels sprouts like cool weather, too much of it will do more harm than good to your plants.

Consequently, you should not grow brussels sprouts in regions with permafrost outdoors but rather use a heated greenhouse that may protect your plants from excessive frost exposure.

The crops of brussels sprouts grow on sorts of vines.

However, the actual plant is rather solid and will look a little bit like kale or other sorts of salad plants.

If you don’t know what sprout plants look like right now, make sure to have a look at one of the videos in this article to get more information in this regard.

Do brussels sprouts grow underground?

Brussels sprouts don’t grow underground. Instead, the whole plant grows above the soil surface and this means that you will also harvest sprout crops above the ground.

In turn, this will make it quite easy for you to determine the optimal harvesting time since you will see the progress your plants make every day and can decide when the right time has come in this regard.

What is the best orientation for growing brussels sprouts?

Since brussels sprouts like the cold, you should not grow them in full sun in south orientation but rather grow them in east or west orientation where sprouts get a healthy mix of sun and shade.

Don’t grow sprouts in north orientation since your plants would just not get sufficient sunlight.

Can you grow brussels sprouts with indirect sunlight?

Instead of growing sprouts with direct sunlight in your garden, you could also grow sprouts with indirect sunlight by using a greenhouse.

However, from my experience, you get better results by just growing sprouts with direct sunlight in your garden instead of in greenhouses on average.

Where do brussels sprouts grow best?

Brussels sprouts grow best in a partially shady spot in your garden where they get a good mix of sun and shade and also get enough space so that they don’t have to compete for sunlight and nutrients with each other.

Never try growing sprouts in dark rooms since your plants would just not get sufficient sunlight to grow well.

Instead, make sure to grow brussels sprouts in bright rooms or even better, do it outdoors instead of indoors to get the best results.

Soil Requirements

Can you reuse soil for growing brussels sprouts the next year?

There is no need to dispose of the soil you’ve already used. Instead, you can use this soil for growing brussels sprouts and other plants for many years as long as you loosen it after every growing season and also add some fertilizer to the soil so that it gets rich in nutrients again.

Do brussels sprouts grow well in waterlogged soil?

Sprouts don’t grow well in waterlogged soil at all.

Instead, the roots of your plants may start to rot and it is therefore crucial that you make sure that excess water will be able to run off properly to protect the roots of your plants and to assure healthy growth in the long run.

How much you have to water brussels sprouts greatly depends on temperatures outdoors and also on how you plant sprouts.

For instance, if you grow sprouts in your garden, you will not have to water your plants during rainy periods of the year at all since your plants can just get rainwater from the soil.

However, during dry periods of the year, you will have to water brussels sprouts on a regular basis to assure an optimal water supply for your plants.
