Time & Duration

When to grow mustard greens from seed?

Since mustard greens grow well in cool weather, the best time to grow mustard greens is spring and fall.

Of course, you can also grow your first batch of mustard seeds in spring, grow other plants in summer and come back to the second batch of mustard seeds in fall to optimize your growing schedule.

Does mustard grow year-round?

While you can grow mustard greens year-round, mustard still grows best during cool periods of the year.

Consequently, if you try growing it in summer, you will most likely not get satisfying yields and I therefore recommend you just grow mustard greens during spring and fall in the main season.

Prepare the soil!

Do mustard greens grow fast?

Compared to most other garden vegetables, mustard greens grow quite fast.

In fact, it will only take around one month to grow mustard greens from seed to harvest while you would have to wait many months to grow melons, pumpkins or even tomatoes to maturity.

How long does it take to grow mustard greens?

It will take you around 35 days to grow mustard greens from seed to harvest on average.

This also greatly depends on the growing conditions you provide to your plants and also on your skill level.

The more experienced you are, the faster you will be able to grow mustard to maturity.

Do mustard greens grow back every year?

Once you harvest the whole mustard plant, mustard greens will no longer grow back.

Hence, if you want to get multiple batches of yields per year, you would also have to sow multiple batches of seeds.

You should also not expect that mustard grows back next year and have to plant new seeds every time you want to get mustard yields in future years.

How long do mustard green plants live?

If you harvest mustard greens on time, your plants will live between one and two months.

However, if you don’t harvest them and just let them grow, your plants will live until the first strong winter frost arrives and this means that if you start growing mustard in spring, they can live up to 8 months in most regions with moderate temperatures.

How long does it take until mustard greens flower?

If you grow mustard greens just to harvest the plant material, you will never see mustard plants flower since they just need more time.

Thus, if you want to save mustard seeds instead, you should let your plants grow for a few months until your mustard plants produce the first flowers.

Can you grow mustard greens in fall?

Growing mustard greens in fall is definitely possible.

Just make sure that you wait until hot summer months have passed but don’t wait too long since otherwise, your plants would not be ready to harvest before winter frost arrives.

Can you grow mustard greens in winter?

Growing mustard greens in winter is not a good idea since mustard is sensitive to frost and you would therefore have to grow it indoors.

In turn, you would not be able to provide natural growing conditions to your plants and this would result in much slower growth behavior.

Location & Climate

Will mustard greens grow in shade?

While mustard grows well with cool climatic conditions, you should still not try growing it in complete shady since your plants would just grow much slower.

Instead, make sure that mustard plants get at least a few hours of sunlight per day on average to assure healthy growth of your plants.

Will mustard greens grow in partial shade?

Mustard greens grow well in partial shade since they get sufficient hours of sunlight while they are still being protected from excessive radiation and heat.

In fact, half-shady environments are the best spots to grow mustard greens and you will even get better results compared to growing mustard in full sun.

Do mustard greens grow best in full sun?

Mustard doesn’t grow best in full sun since mustard likes the cold and if you grow it in full sun, it will just be too warm for your plants.

Hence, make sure to choose a partially shady spot around your home to provide perfect growing conditions instead of exposing mustard to full sun all day long.

Will mustard greens tolerate frost?

While mustard greens like cool weather, they still don’t like frost at all.

Consequently, you should wait with transplanting mustard greens outdoors until you don’t expect frost anymore to protect your plants from frost exposure as best as possible.

Do you have to protect mustard greens from the sun?

There is no need to actively protect mustard plants from the sun.

Instead, just choose a spot where your plants get a healthy mix of sun and shade and your plants will be protected from excessive sun exposure in a completely natural manner.

How much space do you need to grow mustard greens?

Since mustard greens grow relatively small, you will not need more than one square foot of space per plant.

Hence, if you have a big garden, you can grow lots of mustard greens and can supply your family and friends with delicious salads.

Will mustard greens grow indoors?

While you could try growing mustard greens indoors, it is not a good idea since mustard plants need the cold to grow well and it would just be too warm indoors.

Rainy climatic zones are perfect environments to grow mustard greens since those plants love cool weather and don’t like too sunny climates that much.

However, still make sure that you choose a spot where your plants get some sun so that they can grow as fast and strong as possible.

Can you grow mustard greens in tropical climatic zones?

Since mustard greens don’t like the heat at all, it is not a good idea to grow them in the tropics.

Instead, you should rather grow bananas, coconuts, papayas, tomatoes and other plants that grow well in those extremely hot climates.

Can you grow mustard greens in regions with permafrost?

Permafrost is not a great environment to grow mustard since even though mustard likes the cold, it is not resistant to frost.

Consequently, if you want to grow mustard in regions with permafrost, you would need to use a greenhouse or grow mustard greens indoors instead of outdoors in the cold.

Do mustard greens grow on vines?

Mustard greens don’t grow on vines. Instead, they grow on plants that can grow big in the vertical but stay rather small in the horizontal.

Mustard greens will also not produce big crops and you will often just plant them to harvest the plant material for making delicious salads out of it.

Do mustard greens grow underground?

Mustard greens don’t grow underground.

Instead, in contrast to onions or garlic, the whole mustard plant grows above the soil surface and this makes it pretty easy for you to harvest mustard greens in time since you just need to look at the size and color of the leaves of your plants.

What is the best orientation for growing mustard greens?

Consequently, instead of growing mustard in water, make sure to use high-quality soil from the garden center.

Can you grow mustard greens with LED lights?

While LEDs or other artificial lighting could help you grow mustard greens indoors, the use of artificial lighting would also lead to a huge waste of energy and money.

Hence, instead of using artificial lighting, make sure to utilize natural sunlight as best as possible.
