Table of Contents

Time & Duration

When to grow collard greens from seed?

The optimal time to grow collard greens is in spring since collard is a cool-weather plant and likes the cold as long as temperatures don’t fall below the freezing mark.

Hence, make sure to grow collard early in the year to get the best results.

Does collard grow year-round?

While you could grow collard greens year-round, the best time to do so is still in spring so that collard is ready to harvest before hot summer months arrive.

If you want to harvest a second batch of collard greens per year, you might also want to start growing the second batch in fall to harvest it right before winter frost arrives.

Do collard greens grow fast?

You will be able to grow collard greens within two months and this is faster than with many other garden vegetables like tomatoes, cucumbers, melons or pumpkins.

Prepare the soil!

However, there are also some garden vegetables that are faster to grow, for example carrots, lettuce or spinach.

How long does it take to grow collard greens?

It will take you between 50 and 70 days to grow collard greens from seed to harvest.

How long it really takes you to grow collard greatly depends on the climatic conditions and also on how well you care for your plants.

The better growing conditions are, the faster you will be able to grow collard.

Do collard greens grow back every year?

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

Consequently, if you want to get new yields for future years, you will also have to sow new seeds every time and start your growing project right from the beginning.

How long do collard green plants live?

If you harvest collard greens in time, your plants will live between 2 and 3 months.

However, if you just let collard grow and don’t remove the plant from the ground, collard can live up to 7 months until the first strong winter frost arrives and your plants eventually decay.

How long does it take until collard greens flower?

Bolting of your plants usually happens when you plant collard greens too early in the year when it is still too cold outside.

In such a case, it will take your plants around one month until you see flowers on collard.

However, please note that you don’t want to see flowers on your collard plants unless you want to save seeds from them since those flowers would take away lots of energy from your plants and the quality of the plant material you harvest may suffer.

Can you grow collard greens in fall?

You can grow collard greens in fall in a decent manner as long as you wait long enough until temperatures outside are no longer too hot but also make sure that you start your gardening project in time so that you can harvest collard before winter frost arrives.

Can you grow collard greens in winter?

You should not try to grow collard in winter since it will just be too cold outdoors and your plants may just decay if you don’t protect them from frost.

Consequently, you would have to grow collard greens indoors where you would just not be able to provide decent growing conditions to your plants.

Location & Climate

Will collard greens grow in shade?

While collard greens grow well with cool climatic conditions, you should still not grow them in complete shade since collard needs at least a few hours of direct sunlight per day on average to grow well.

Will collard greens grow in partial shade?

Growing collard greens in partial shade is perfectly fine since your plants will get a decent mix of sun and shade and will therefore get sufficient sunlight while they are still being protected from excessive sun exposure and heat at the same time.

Do collard greens grow best in full sun?

Collard is not one of the plants that grow well in full sun. In fact, collard greens also need a certain amount of shade to grow well.

Hence, instead of growing collard in full sun, you should rather grow collard greens with a healthy mix of sun and shade to get the best results.

Will collard greens tolerate frost?

While collard is quite resistant to the cold, too much of it can greatly damage your plants and you should therefore not expose your collard plants to strong frost.

Instead, make sure to wait with growing collard outdoors until you don’t expect that temperatures fall below the freezing mark anymore.

Do you have to protect collard greens from the sun?

You should not actively try to protect collard greens from the sun.

However, since collard doesn’t like the heat, you should choose a spot where your plants get a good mix of sun and shade so that collard greens are protected from the sun in a completely natural manner.

How much space do you need to grow collard greens?

Since collard greens can grow relatively bushy, you should plan at least 2 square feet of space per plant.

Of course, if you have a big garden, you can provide your plants with even more space since more space also means higher yields on average since your plants will not have to compete for sunlight and nutrients with each other.

Will collard greens grow indoors?

Growing collard indoors is not a good idea since collard likes cool weather and you will just not be able to provide those cool conditions indoors.

Moreover, your plants would also take away lots of space from you.

You would also have to clean your home more often and I therefore recommend you rather grow collard outdoors instead of inside your four walls.

Can you grow collard greens without a garden or balcony?

In case you don’t have access to a garden or balcony, you would have to grow collard indoors.

However, there are many issues related to it and you would also not be able to provide natural conditions to your plants.

In turn, chances are that your yields would also be much lower compared to growing collard outdoors.

Can you grow collard greens in small flats?

Growing garden vegetables like collard in small flats is not a good idea since your plants would just take away too much precious space from you.

Consequently, I suggest you wait with growing collard greens at home until you move to a bigger place where you are no longer space-constrained.

Can you grow collard greens in an aquarium?

Some people also try growing collard in aquariums.

However, this is usually not a good idea since water will often not be able to run off and waterlogging may become an issue.

Thus, the roots of collard plants may start to rot and your plants may not grow well in the long run.

Can you grow collard greens in a terrarium?

You should also not try to grow collard greens in a terrarium since you would be quite inflexible when it comes to moving the terrarium since it will get quite heavy once it is filled with potting soil.

Moreover, waterlogging will also become an issue and you should therefore rely on conventional flower pots instead.

Can you grow collard greens in buckets?

Buckets are great alternatives to conventional flower pots when it comes to growing collard.

Just make sure that water will be able to run off properly and also that you use big buckets so that collard greens get sufficient nutrients and sunlight.

Can you grow collard greens in bags?

You might also want to grow collard greens in bags.

This is perfectly doable as long as you choose stable fabric bags where water can run off properly at the same time.

Also make sure to fill those bags with high-quality potting soil from the store to get the best results.

Can you grow collard greens in hanging baskets?

Since collard greens don’t produce heavy crops, you will also be able to grow them in hanging baskets in a decent manner and don’t have to fear that those hanging baskets or your plants may get destabilized in the long run.

Can you grow collard greens in rainy climatic zones?

Collard is a cool-weather plant and you will be able to grow it in rainy climatic zones.

However, still make sure that you provide a sunny spot for your plants so that they can use the rare occasions the sun comes out as well as possible.

Can you grow collard greens in tropical climatic zones?

The tropics are not a great place to grow collard since collard greens don’t like the heat at all.

Consequently, instead of growing collard, you should rather grow plants like bananas or tomatoes that are more used to the heat.

Can you grow collard greens in regions with permafrost?

You should not try growing collard in regions with permafrost since it would just be too cold outdoors and you would have to grow it in a heated greenhouse, which would cost lots of energy and money and growing collard at home would just not be worth it under those conditions.

Do collard greens grow on vines?

Collard doesn’t grow on vines but rather grows on rather compact plants.

You will also not be able to harvest collard crops at the end of the growing season but you will rather harvest the plant material that you can use for salads or other dishes.

Do collard greens grow underground?

Collard greens don’t grow underground. Instead, in contrast to garlic, potatoes or onions, the whole collard plant will grow above the soil surface and this will also make it quite easy for you to harvest your plants since you can see the progress your plants make every day.

What is the best orientation for growing collard greens?

While you could grow collard in south orientation, it would be even better to grow it in west or east orientation where collard greens are better protected from excessive sun exposure.

However, never try growing collard in north orientation since your plants would just not get sufficient sunlight.

Can you grow collard greens with indirect sunlight?

While you could also grow collard with indirect sunlight in greenhouses, you will get much better results by just growing it outdoors in your garden or on your balcony from my experience and I therefore recommend you just go for the most natural form of gardening.

Where do collard greens grow best?

Collard grows best if you provide a spot where your plants get a healthy mix of sun and shade while they are still being protected from heavy storms and other adverse conditions outdoors.

Consequently, growing collard greens in your garden or in raised beds is perfectly fine.

Where to grow collard greens in pots?

Growing collard greens in pots is perfectly doable as long as you use big pots and also place those pots in a half-shady environment where your plants get a good mix of sun and shade while they are still protected from harsh conditions and also from animals outdoors.

Where to grow collard greens indoors?

If you really want to grow collard indoors, you should choose a cool room while still making sure that your plants get sufficient levels of natural sunlight so that collard greens can grow in a decent manner.

Can you grow collard greens in water?

You should not try growing collard greens in water since your plants would just not get sufficient nutrients.

Instead, make sure to grow collard in high-quality soil so that your plants get everything they need to prosper and to deliver great yields.

Can you grow collard greens with LED lights?

You could also use LEDs to improve growing conditions for collard indoors.

However, from my experience, LEDs are not a suitable substitute for natural sunlight and the use of artificial lighting will also consume lots of energy.

Consequently, instead of relying on artificial lighting, make sure to use natural sunlight for your gardening projects as best as possible.

Can you grow collard greens in dark rooms?

Growing collard greens in dark rooms is not a good idea at all since your plants would just not get sufficient levels of sunlight and would not deliver great results.

Hence, instead of growing collard in dark rooms, grow it in bright rooms or, even better, outdoors.

Soil Requirements

Can you reuse soil for growing collard greens the next year?

You can reuse soil for growing collard multiple times as long as you make sure that you loosen the soil after each growing season and also make sure that you add some fertilizer to the soil so that every new generation of collard gets sufficient nutrients.

Do collard greens grow well in waterlogged soil?

Do collard greens grow best in acidic, neutral or alkaline soil?

Collard grows well in slightly acidic to neutral soil with an optimal soil pH of 6.4 – 7.

However, while this may sound complicated, you will be perfectly fine in this regard as long as you rely on a decent soil mix from the garden center.

Will collard greens grow in sandy soil?

Sandy soil is not a great medium to grow collard since it often doesn’t contain lots of precious nutrients.

Consequently, if the fraction in the soil is too big, you may want to add some high-quality soil from the garden center to provide better conditions for collard plants.

Will collard greens grow well in clay soil?

You should not grow collard greens in clay soil since it is just too solid and water will not be able to run off properly.

Consequently, waterlogging may become an issue and the roots of your plants may start to rot.

Will collard greens grow in compost?

While you should not grow collard greens in pure compost since it will just not have the right soil pH most of the time, you could mix compost and soil from the garden center and you will create a perfect soil environment to grow collard and many other plants.

Plant Care

Collard greens don’t need lots of water while they are still young.

However, once they grow bigger, the water demand of collard greens grows exponentially and watering collard greens can turn into real work.

Do you have to water collard greens on a regular basis?

If you grow collard greens outdoors in your garden, you will not have to water them during rainy periods of the year since your plants would just get sufficient rainwater from the soil.

However, during dry periods, you should water collard greens on a regular basis so that your plants don’t dry up.

Should you use filtered or unfiltered water to water collard greens?

You don’t have to spend any time filtering tap water for collard greens.

Instead, unfiltered water is perfectly fine to water collard as long as you don’t live in one of those regions where the fraction of lime in the water is too high.

Should you use rainwater to water collard greens?

Rainwater is great to water collard and many other garden vegetables.

Hence, if you want to rely on rainwater in this regard, make sure to install a rainwater barrel in your garden to collect water during rainy periods that you can use during dry periods of the year.

When to stake collard green plants?

While there is no real need for staking collard plants, you may still want to do so to stabilize your plants in a perfect manner.

However, you should still wait with staking collard plants until they reach a height of at least 3 inches.
