kale Harvest Period

Although kale takes 55 to 80 days before maturity, you could harvest baby kale after 30 days. If the plant is four inches tall, you could start harvesting baby kale leaves. 

Then, mature leaves will be harvested upon a certain period of time. For plants that were directly seeded into the garden bed, it would normally take 70-80 days. But for transplanted, you could expect your plant to mature after 55 days. 

While the harvest period of this plant does not require a special season, here are some special scenarios that you should consider.

  1. Harvest during summer

    Extreme heat brought by summer could be a bit unrewarding. Leaves are tough and overly bitter which makes it inedible. 

    With that, use a stronger tool to cut the leaves from its stem. And to ensure that the tough and bitter leaves won’t be harvested for the next season, harvest 90% of the leaves from the stem. 

    Just make sure to retain a few leaves on the stem for the next season to come
  2. Harvest during winter

    Some experts recommend waiting until winter to harvest your crops. According to them, this time improves the taste of kale. 

    The frost increases the amount of sugar in kale which makes the leaves sweeter. This would be perfect for those people who don’t like kale because of its bitter taste.

Process Of Harvesting Kale

Now that you’ve got a clear picture of the right conditions to grow your kale into a healthy mature plant, let’s get to harvesting. Harvesting kale could be really rewarding since continuous harvest could be done. 

Process of Harvesting Kale

Kale leaves could be harvested when the leaves are about the size of your fist. Avoid waiting for the leaves to grow bigger, as the leaves become tough and inedible. Yellowing and discoloration of the leaves is also a sign of overmature leaves.

As you can see from your plant, the leaves are attached to a central stem. It will grow from the top of the stem, while the stem grows taller. 

Therefore, start picking on the outermost leaves or the leaves on the bottom-most part. These leaves are the most mature ones and the bigger ones. By starting on the outermost, the produce of the plant is maximized.

Do not cut the stem or the smaller leaves in the inner circle of leaves. This could stop the regrowth of new leaves, or worse, kill the plant.

The center area of the plant, which means the stem and the innermost leaves, will let the plant from producing throughout the year.

Therefore, do not overharvest. Harvest only a fistful of leaves and leave at least one third of the leaves on the stem. You could always come back to harvest again anyway.

But if the need arises, you could harvest the leaves, just leave 5-7 leave intact.

Harvesting Tips

Although leaving a few leaves after harvest could assure continual harvest for the next season, kale plant could only withstand 32 degrees Fahrenheit. Temperature lower than 32 degrees could hinder the growth of Kale and therefore cause death to the plant. 

But don’t worry, there are some ways to protect your plants from extreme temperature. Use row covers, hoop houses, cold frames, tarp with hay. These equipment could trap the heat and act as insulation. 

You could still harvest during the winter, but do not remove the covers. Just reach out to the bottom cover. Then, gradually pick the leaves. But you could always leave the kale to grow over winter and harvest in spring. 

On the other hand, summer could toughen the leaves which makes it inedible. But if you want to enjoy your kale leaves in summer, you could still do. Just harvest the leaves before it matures for normal texture.
