  • Kale microgreen seeds – you can purchase them either in the form of a distinct blend of microgreen seeds or regular vegetable seeds (the former is ideal for beginners)
  • Soil – with organic potting soil as the preferable option
  • Growing Medium – it could be a container, hemp mats, tray, or whatever medium you opt for maturating the kale
  • Light natural (sunny window) or artificial method (grow lights)

  • Nutrients (optional) specifically recommended if you intend to grow the kale microgreens hydroponically.

How to Grow Kale Microgreens in Soil?  

Getting Ready

Before everything else, prepare the seeds, a growing medium, and an empty spray bottle. The kale microgreen seeds you’re going to use must be from a reputable supplier. This one is important, or else you will end up with infected or weak growing plants.

If you intend to use a tray, a 10×20 dimension is sufficient. Get two trays – one to hold the plants and another to store the water underneath. Your growing medium could be sterilized soil for added nutrients to ensure it will grow bloomingly.

Some use earthworm castings, while others find coconut coir a much ideal alternative. Besides the adequate amount of nutrients your plants will get, they are also well-sheltered from extreme wet.


Stock up the tray or container with soil. Spread the seeds across the soil surface. You don’t have to overcrowd since the kale plants won’t be in there for longer, neither get it to space out uniformly or even out seamlessly.

Take a little bit more soil and then scatter over the microgreen seeds. Press down your hands lightly to lay them inside. Be sure not to compress too much.


For the last planting step, give your kale plants an appropriate drink of water. Use a clean spray bottle to do so. But be cautious! You don’t want them to dip in a pool of water. As long as they’re incredibly moist, you are good to go on the next step.

Cover Up

Only use a light-tight cover to keep all the sources of light out. Assuming you are using a 10×20 plant breeding tray, you can use the same tray measurement to cover the plants by flipping it upturned. Any covering materials will work, though, providing you keep the plants in absolute darkness.

Give Sunlight

After two or three days and you notice the initial signs of germination, it’s time to give your kale some light. Place the growing medium in an area where the sun loves to show up. Another alternative is to put it directly beneath a grow light. See the instructions indicated on the product to know how close the light should be and other related information.


Watering doesn’t only stop after the planting process. Like flowers and other plants, you also need to ensure the kale microgreens are receiving adequate water after uncovering them. You don’t have to mist them. Just pour small amounts directly inside the container or tray. Either use a hydroponic solution or water using pH balanced water.


What makes microgreens a popular indoor and outdoor plant is how quickly they develop. Within ten to twelve days, you can have them on your kitchen table and enjoy their healthful benefits.

To harvest, cut in the stem base with a sharp blade. You will know the plants are ready to harvest if the leaves are wide open and green. Rinse and dry well, then put between damp paper towels in a ziplock or plastic bag.

Store in your refrigerator to lengthen their shelf life. You can get them whenever you want to prepare healthy dishes.

How to Grow Kale Microgreens with a Grow Mat?

Soak the Mat and Seeds

First, you have to cut the mat with a size fitted to the growing medium you’re going to use. But if you already have a pre-cut mat, you can skip this step. Now, soak the grow mat and seeds in water for quite a few hours – around 6 to 8 hours (ideally for seeds).

Put the Grow Mat

Place the grow mat of your choice in a propagation tray or container. Sprinkle with a suggested amount of seeds as evenly as possible.

Keep in Dark

You may choose to put the plants in a moisture arena and keep them in the dark for up to four days. It promotes stalwart rooting and high sprouting.

Place Under A Natural or Grow Light

Otherwise, omit the step above and allow the plants to have access to sunlight or grow light. They will need it for approximately 8 to 10 hours regularly. It should not be too damp.

Give A Good Spray

While waiting for the new growth, mist with water once or twice every day. It will keep the mat properly saturated as well. Never allow it to dry out.

It’s Harvest Time!

Once ready, get a scissor, and harvest your crop. Enjoy having those delectable greens on your plate!

How to Grow Kale Microgreens on Wood Shavings?

This propagation process is sometimes called confetti. Wood shavings are not reusable and could be somewhat cluttered compared to other methods here.

But on a positive note, our mother nature would definitely approve of it to breed your kale microgreens due to its sustainable feature. Not to mention compostable.

Purchase it from the feed store or one specifically tailored for growing microgreens. The process is similar to flourishing kale plants in soil, only that you have to use the wood for stuffing the flat.

Soak the Wood Shavings

You first need to soak the wood shavings in water for a handful of hours, then fill in the flat. Put a little bit into place.

Add Seeds

Sprinkle the seeds squarely over the surface. You should leave some space between the seeds. Let’s say a half-centimeter or up to three centimeters.


Another good thing about using wood shavings is that they require less water since they have a decent amount of moisture. Be careful not to overdo watering the plants.

Care for Plants

Your seeds have now germinated. Finally! Allow the plants to get enough sunlight directly through the sun rays or grow light. Doing so will encourage healthy growth.


Grab a pair of scissors or a blade and then cut off piece by piece. Wash around three to four times before drying out on a paper towel. Store in a tightly sealed vessel until you are ready to use for your favorite recipes.

How to Grow Kale Microgreens on Growing Paper?

If you are looking for a clean alternative to wood shavings, the growing paper might satiate your interest. It holds moisture too. There’s no need to cut it out because most are perfectly sized to fit any standard container or tray. 

Soak the Paper

Soak for quite a few hours and do the same for the seeds as well. Have two tablespoons of kale seeds and put them in a clean glass or cup along with water.

Place In The Tray

Get the growing paper and place it in the lowermost of a container or tray. Make sure to exhaust surplus water thoroughly.

Sprinkle Seeds

Spread out the seeds across the paper. Using this method will require less intricate work as you won’t have to prepare any covering supply. Just leave it as it should be.

Add Water

Spray a virtuous amount of water as necessary to keep the paper moist and further assist with fast, healthful sprouting.


And just as you do in soil, mats, and wood shavings, set the plants in a sunny window or have a grow light in your space.

Ready to Harvest

The seedlings usually take one week or so to sprout before ready to cut off and consume.

How Can You Speed Up Growth?

We understand the excitement of picking your healthy kale microgreens after a few days of planting and taking care of them. Although relatively small, these green plants are a massive trend you can usually find anywhere – from food stores to corner cafes and restaurants. Add them to your sandwich, salad, and any recipes you adore.

However, do remember that growing kale microgreens is not all about reaping benefits. There are hitches, too, such as the likelihood of getting the plants infested or slow growth. To avoid such a scenario, the following are essential tips you should start taking on board now.

Tip #1: Invest in A Commercial Kit

Kale microgreens do not support expensive planting and growth, so a commercial kit is optional. But since we are talking about fast sprouting, why not take the valuable risk? You can choose a simple sprouter medium. If you like a fancy option, there’s an array of commercial kits with implanted seeds in the grow mat.

Tip #2: Consider the Best Lighting

Unless you’re living in an area where summer, spring, or fall mostly arises, you should not worry too much about your plants getting adequate sunlight. A window that faces west or east is your best pick. In case your climate temperature continually deals with winter, your plants need a sunny south-facing windowsill.

Kale microgreens are typically reaped very early than traditional plants, so spending hundreds of dollars on an over-the-top grow light is not recommended. Go for starker options, such as tabletop or gooseneck light. Another low-cost alternative is the fluorescent bulb. So long as it perfectly fits the tray or container.

When using a commercial grow light, leave it on for sixteen to eighteen hours daily. Some have an automatic timer feature so you can sleep at peace or do other errands without checking the time recurrently. It automatically turns the light off as soon as the plants have reached the desired light intensity.

Tip #3: Use A Heat Mat

A heat mat has been a go-to option when it comes to fast-tracking microgreen growth, and we’re sure you will also love adding it to your gardening supplies. It is waterproof initially used for seed starting. But today, many gardeners and plant enthusiasts are relying on it to nurture seeds quickly than before.

What this mat basically does is elevate the soil temperature – approximately ten degrees. Hence, creating an ideal environment for quick plant propagation. Fret not, as this material won’t cost you huge bucks. It comes at a relatively cheap price tag designed for long-term use.

Tip #4: Add Organic Fertilizer

Kale can protect itself against pests. However, its shielding capabilities have limitations as well. Cutworms, aphids, etc., can heavily affect your harvest.

If you don’t want to start from scratch, consider adding organic fertilizer. It is a natural, effective way to prevent diseases and pests from ruining your effort and lovely greens.

Tip #5: Plant Alongside Bordering Plants

As the saying goes, no man is an island. People tend to live happier and healthier in the company of others. The same goes for kale plants.

They generally flourish along with herbs and other varieties, including beetroot and cabbage. Not only will you get the germination faster, but you will also enjoy a fruitful of nourishing plants in your garden or backyard.
