When and How to Harvest Kale

One of my favorite things about kale is its easy and prolonged harvest. It’s the ultimate cut-and-come-again option for your veggie garden.

Along with being quick and easy to pick, this leafy green is packed with antioxidants and vitamins A, C, and K. After plants mature, it takes just a few minutes to gather enough greens for a tasty and nutritious meal.

Kale is an easy vegetable to grow and harvest. However, you still have to know the right time and method to harvest.

The timing and methods you use depend on if you are growing plants for baby greens or mature leaves. Continue reading to learn how to get the most from this nutritious green.

When to Pick Kale

Kale is ready to pick approximately 60 days after seeds have been planted. At this point, healthy plants will have upwards of ten leaves, with small ones in the center and larger ones on the outside.

If you’re looking to grow baby kale, plants will be ready to pick and enjoy in 25 to 30 days after they are sown.

The harvest period usually occurs once in late spring or early summer, and again in autumn.

It is worth noting there isn’t a perfect time to pick this green. If you like smaller leaves, collect them earlier when they are younger. And if you prefer larger kale, wait until it sizes up.

If you wait too long, however, older leaves may become discolored and eventually fall off the plant. If this happens, just remove and discard any leaves that have gone bad and continue harvesting.

After the first harvest, you can come back for more when the leaves have grown to about the size of an adult hand. Depending on your growing zone and the time of year, you can gather new greens every one to two weeks.

How to Harvest Mature Kale

All varieties of this vegetable are harvested in the same way.

For mature plants, grasp the stem of a mature outer leaf at the base of the main stalk and pull down and out, away from the center, until it breaks. Repeat this process to pick all the greens you want.

Make sure to leave at least five central leaves on the plant so it can continue to photosynthesize and produce new growth.

Never pick the innermost portion with the smallest leaves, as that’s where new growth originates.

If your soil is soft or your plants are newly established, you can use a knife or scissors instead of your hands. This prevents you from pulling the whole plant out of the ground or snapping the main stalk.

If you see discolored or heavily insect-eaten leaves, make sure to remove these and discard them, or add them to the compost pile. This allows the plant to put its energy into new and healthy growth.

It’s also a good time to check for slugs, aphids, and other damaging pests.

How to Harvest Baby Kale

If you’re growing baby greens for salads, they will be ready in 25-30 days. The Red Russian variety is often grown for these small leaves.

Remove by using your fingers to pinch off individual leaves at the base of the stem. If you prefer, you can cut the stems with scissors or a knife.

My preferred method is to grab a handful and cut them off one to two inches above the ground, using a knife. This is a quick process that allows the plant to continue growing for future harvests.

When choosing where to cut, consider the growth point. On a kale plant, this is the central portion of the plant where stems converge and new growth emerges.

To allow new growth, cut the stems above the growth point.

To do this, cut just below where the stem connects to the larger leaves. This will leave the smaller ones intact so the plant can continue growing.

Grab Some Greenery

Now that you know how to pick them, go out and get yourself some of these nutritious greens. Their flavor and versatility will reward you for weeks to come.

Friends who inherited an old, large garden offered me an opportunity to come into their somewhat overgrown garden and dig up what I wanted to take home and try planting in pots on my balcony. As they had small beautiful chard popping up literally in the lawn, I took a few of those, and they have massive *stands* of what I now believe to be overgrown Russian Red kale. I have no experience with kale not planted from seed so I took a couple of those too, because why not. The chard is doing great. bright, fresh, growing well. My… Read more »

One thing that some gardeners like to do is allow their kale to overwinter and then bolt in the second season, as you’ve described, and then harvest the flower stalks for eating as “napini kale.” The stalks and flower clusters are edible before they bloom, and some kale cultivars are more tender than others.

Otherwise, yes, you could allow them to finish flowering and collect the seeds for replanting. ‘Red Russian’ is an heirloom cultivar, so it should grow true to seed, unless it’s been cross-pollinated with something else.

Briana, I’ve had a kale plant growing on my balcony for well over a year. I’ve made quite a few salads from the one plant. It is still healthy and growing strong. My question is regarding the stalk. With all the harvesting, the stalk is now bare and is about 8-10″ tall, with a full crop of leaves at the top. It’s almost like a palm tree! Is there a way to get the leaves to start growing down lower on the stalk at this point? Meanwhile, I’ve planted a second one next to it and it is also doing… Read more »

Hi Adrienne! Once the stalk has gotten that tall and is sprouting at the top like a palm tree (perfect description!), there’s no way to force it to produce leaves lower down again. If you decide to harvest the whole plant, you can always cook up the stalk – it’s tasty and so many people throw it out without realizing how good it is.
Your garden sounds incredible, what other plants do you have going besides kale?

Thanks for the reply! I just started some new kale seedlings. Two kale plants produce well, but it will be nice to have extra to add to smoothies.   So this year I decided to experiment with 3 raised garden beds, each 48″ long, and a variety of pots. I know I squeezed in more plants than advised, but so far it’s working out!   I have already harvested two nice sized broccoli florets, and now little ones are appearing. I’ll make a list below of what I’ve got growing. Any advice from you will be so appreciated!   Tomatoes… Read more »
