Benefits of Growing Kale in Containers


Kale is an annual plant that is grown from its seeds. It can thrive in a wide-range of temperatures but it’s mostly a cool-weather plant.

The enemy of most plants is winter. The kale, though, can survive at up to -15℃. 

Fun fact:

Kale actually becomes sweeter after a frost. 

Anyway, why should you grow kale in containers? Whether you are trying to grow the food variety or the ornamental kind, there are a number of benefits in container gardening. 

Easier to move around

Kale is generally easy to grow. You already have that going for you. 

When you put them in pots, it’s even easier to monitor their growth while also making sure they are in a comfortable environment. 

Let me elaborate

While kales thrive in cold environments, you don’t want snow to cover it. So, when it’s snowing out, you can just easily keep the potted plants away from the snow. 

The same could be said when it’s summer. Kale is a cold-weather crop. It’s also more delicious when it has experienced a bit of frost. 

So

When it’s the middle of summer and it’s really hot, you might want to keep the pots away from the heat of the sun.

Easy to care for them

Potted plants need more care because they don’t have a lot of leeway to grow. This means that during summer, you would have to constantly monitor the soil moisture. 

You also need to fertilize more frequently. 

On the brighter side

It’s very easy to water them appropriately because they are already in pots. 

It’s also easier to fertilize. 

Change decorations anytime

For ornamental plants, you can change their locations anytime you feel like it. 

In essence

You are changing the ambiance and how your home looks when you feel like it. That’s how easy it is with potted decorative plants. 

They would be great at upgrading the interiors of your home.

You know, with just a few pots of kale, you can already feed your entire family. And remember, there are so many ways to use the kale.

So, how do we plant kale?

Note on the containers:

Give the kale enough place to grow. Find a container that is around 12 inches in diameter. Something a little deeper, too, to give the roots a lot of room to grow. 

They should have proper drainage. 

2. Sow your seeds

Sow the seeds indoors. 

Also, it’s important that you plant the kale between the fall and early spring. Always remember that kale thrives better in the cold.

Spacing

For a small container, the kale can be at least four inches apart. You can adjust the space in between depending on the size of your container. 

Check the seed label about appropriate sowing and care for the particular cultivar you got. 

3. Allow containers to have access to sunlight

Kale may love the cold but it also needs to have sunlight to grow healthy. Make sure you put the container in a place where kale can have at least six hours of sunlight. 

4. Water as needed

To know if you need to water your kale, you need to touch the soil. If it’s dry, then you need to water. 

The soil needs to be moist at all times. 

5. Fertilize

You need to fertilize at least every week during the early growing season. Then you can adjust it every two weeks. 

6. Harvest

You can start harvesting kale in two months. That’s how fast it grows. 

But to make sure that you are not harvesting it too early, a good rule of thumb is when the size of the leaves are about the size of your hand. 

You’re ready to reap

Pick the leaves one by one starting with the outermost leaf. 

Leave the small ones, those in the middle, so they will continue to grow. 

The good news!

You may be able to harvest again in a week or so. 

That’s how amazing kale is!
