This article will explore the process of growing kale from seed to harvest. We’ll cover everything from soil preparation to pest management so that you can enjoy a bountiful kale harvest right in your backyard.

What Is Kale?

Kale is a leafy green vegetable that has recently gained much popularity.

It’s unsurprising, given that it’s packed with essential nutrients like vitamins A, C, and K and minerals like calcium and iron.

But what exactly is kale, and where did it come from?

Kale is a member of the cabbage family and is closely related to other cruciferous vegetables like broccoli, cauliflower, and Brussels sprouts.

It’s believed to have originated in the eastern Mediterranean and Asia Minor, where it has been grown for over 2,000 years.

In the past, kale was primarily used as a decorative plant, with its leaves used as garnishes.

However, in recent years, kale has become increasingly popular as a nutritious and versatile vegetable that can be enjoyed in various ways.

Kale comes in various types, including curly, flat-leaf, and ornamental kale.

Each type has unique characteristics, ranging from flavor and texture to color and appearance.

Kale Can Survive Even the Coldest Winter

Kale is a hardy vegetable that can withstand cold temperatures and even snow. In fact, it tastes sweeter after being exposed to frost.

Choosing Your Kale Variety

Now that we know what kale is let’s talk about the different types of kale available and which one is right for you.

  • Curly Kale – This is the most common type of kale, with a crinkly texture and deep green leaves. It has a slightly bitter taste and is excellent for salads, smoothies, and stir-fries.
  • Lacinato (Dinosaur) Kale – This variety has dark green, long, narrow, smooth, flat leaves. It has a sweeter taste than curly kale and is excellent for making kale chips or sautéing.
  • Red Russian Kale – This type has red-tinted leaves with a flat, serrated edge. It has a slightly sweet taste and is excellent for adding color to salads or sautéing.
  • Ornamental Kale – This kale is not typically eaten but is grown for its beautiful appearance. It has a variety of colors and textures, making it perfect for adding interest to your garden.

When choosing your kale variety, consider your taste preferences, cooking methods, and the look you want to achieve in your garden.

Feel free to try different types of kale to see which one you like best.

Once you’ve chosen your kale variety, it’s time to move on to the next step: preparing your soil.

Preparing Your Soil

Before you can plant your kale, you must prepare your soil to ensure your plants have the nutrients and conditions they need to grow healthy and strong.

Here are the steps to follow:

  1. Choose a sunny spot – Kale loves the sun, so choosing a spot in your garden with plenty of direct sunlight is essential.
  2. Clear the area – Remove any weeds, rocks, or debris from where you plan to plant your kale. This will prevent them from competing with your plants for nutrients.
  3. Test your soil – It’s essential to test your soil to determine its pH level and nutrient content. Kale prefers soil with a pH level of 6.0 to 7.5. You can purchase a soil test kit at your local garden center or online.
  4. Add compost – Once you know the nutrient content of your soil, you can amend it as needed. Kale prefers well-draining soil that’s rich in organic matter. Adding compost to your soil will help improve its texture and fertility.
  5. Fertilize – If your soil is deficient in nutrients, you may need to fertilize it before planting your kale. Choose a balanced, organic fertilizer and follow the instructions carefully.

Planting Kale

Now that you’ve prepared your soil, it’s time to plant your kale.

Follow these steps for a successful planting:

  1. Choose the Right Time – Kale can be planted in spring and fall. Wait until the soil temperature reaches at least 50°F (10°C) before planting in the spring. In the fall, plant 6-8 weeks before the first frost.
  2. Space Your Plants – Kale needs plenty of room to grow, so space your plants 18-24 inches apart.
  3. Plant Your Seeds – If planting your seeds, plant them 1/2 inch (1.25 cm) deep and 3 inches (7.5 cm) apart. Once they’ve sprouted, thin them to the proper spacing.
  4. Water Your Plants – Keep your soil moist but not waterlogged. Water your plants deeply once or twice a week, depending on your climate and soil conditions.
  5. Mulch – Adding a layer of mulch around your plants will help keep the soil moist and prevent weeds from growing.

Caring for Your Kale Plants

Now that your kale is growing, caring for it properly is essential to ensure a successful harvest.

Here are some tips for caring for your kale plants:

  • Watering – Water your kale regularly, ensuring the soil stays moist but not waterlogged. Avoid watering from above, as this can lead to disease and pests.
  • Fertilizing – Kale is a heavy feeder and will benefit from regular fertilization. Use a balanced fertilizer every four to six weeks.
  • Mulching – As your kale grows, add more mulch around the base of the plants to keep the soil moist and prevent weeds.
  • Pruning – Prune your kale regularly by removing any yellowing or damaged leaves. This will help to keep your plants healthy and productive.
  • Protect from pests – Look for pests such as aphids and cabbage worms. Use row covers or organic insecticides to protect your plants.
  • Support – If you’re growing a tall variety of kale, you may need to provide support for the plants as they grow.

Harvesting and Storing Kale

Harvested kale

Kale is ready for harvest when the leaves reach the size you prefer.

However, you should avoid picking the baby leaves during the first month of growth, allowing the plant to establish itself before harvesting.

Generally, mature kale plants are ready for harvesting 55-75 days after transplanting, depending on the variety.

How To Properly Harvest Kale Leaves?

To harvest kale leaves, use a sharp pair of scissors or a knife to cut the stem about two inches (5 cm) above the soil level.

Cut the outer leaves first and leave the center of the plant to continue growing.

Don’t pull the leaves off the plant, or you may damage the growing point of the stem, which will slow down future growth.

Tips for Storing and Preserving Kale

Kale is best used fresh. However, you can store kale in the refrigerator for up to a week or two, depending on its freshness when harvested.

Follow these steps to store kale properly:

  1. Rinse the kale leaves in cold water and dry them thoroughly with paper towels or a salad spinner.
  2. Remove excess moisture from the leaves and wrap them in a damp paper towel.
  3. Store the wrapped kale leaves in a plastic bag or airtight container and keep them in the refrigerator’s crisper drawer.

Alternatively, you can blanch and freeze kale for long-term storage.

First, blanch the kale leaves for two minutes in boiling water, then cool them immediately in ice-cold water.

Dry the leaves thoroughly and pack them in freezer bags or containers.

Frozen kale will last for up to eight months in the freezer, and you can use it in smoothies, soups, stews, and casseroles.

Kale Can Be Used To Revitalize Your Skin

Some people use kale topically as a skincare ingredient due to its high levels of vitamin C and antioxidants.

Common Problems and Solutions

Even with proper care, kale plants may encounter some issues.

Here are a few common problems gardeners may encounter when growing kale and tips on addressing them.


Aphids, cabbage worms, and flea beetles are some of the most common pests that can infest kale plants.

To address these pests, you can use insecticidal soap, neem oil, or pyrethrin spray.


Kale can be susceptible to fungal diseases such as powdery or downy mildew.

These can be prevented by planting kale in well-draining soil and not overcrowding the plants.

Remove affected leaves and ensure proper airflow around the plants if you notice signs of disease.

Yellowing Leaves

If your kale leaves start to turn yellow, it could indicate a nutrient deficiency.

Add some organic fertilizer to the soil to give the plant nutrients.


Bolting is when the plant goes to seed prematurely, often due to hot weather. Once the plant starts to bolt, the leaves will become bitter and harsh.

Plant kale in cooler months or partially shaded areas to prevent bolting.


Congratulations, you’re now well-equipped to grow your very own kale garden!

Remember, choosing a suitable variety, preparing the soil, proper planting and caring techniques, harvesting at the right time, and addressing any problems are all crucial to a successful harvest.

So, grab your shovel and start growing this delicious and nutrient-rich superfood!
