Did You Know?
1. Kohlrabi, a member of the cabbage family, is a unique vegetable that originates from Germany. Its name is derived from the German words “kohl” meaning cabbage and “rabi” meaning turnip.
2. Contrary to popular belief, kohlrabi is not a root vegetable; rather, it is an enlarged stem that grows above ground. This peculiar trait gives it a crisp and crunchy texture when consumed.
3. Although it seems like a one-time harvest, kohlrabi has the ability to regrow new shoots for a second harvest after the initial bulb has been harvested. This process is known as “ratooning,” and it allows for multiple harvests throughout the growing season.
4. Kohlrabi is rich in essential nutrients such as vitamins C and K, potassium, and fiber. Moreover, it is a low-calorie vegetable, making it a nutritious and guilt-free snack or addition to any dish.
5. In some cultures, kohlrabi leaves are not wasted but used as well. They are commonly cooked and consumed similarly to spinach or collard greens. This practice provides an additional source of nutrients and reduces food waste.
Factors That Can Affect Kohlrabi Bulb Growth
Kohlrabi plants are known for their edible bulbs that can be harvested and enjoyed. However, in some cases, these plants may not produce a bulb. There are several factors that can contribute to the absence of a bulb in kohlrabi plants.
One possible reason is that the plants were spaced too closely together. Proper spacing is crucial for kohlrabi plants to develop healthy bulbs. It is recommended to space them 6-9 inches apart to allow enough room for the bulbs to grow.
Extreme heat or frost can also be detrimental to the development of kohlrabi bulbs. These temperature extremes can stress the plants and inhibit bulb formation. Additionally, keeping kohlrabi plants in shade for an extended period can prevent bulb growth.
Lastly, water deprivation can also impact bulb growth in kohlrabi plants. Adequate and consistent watering is essential for the development of healthy bulbs. Lack of water can cause the bulbs to become stunted or fail to form altogether.
Important: even if the bulbs do not appear, the stems and leaves of kohlrabi are still edible and can be enjoyed in various dishes.
- Proper spacing (6-9 inches apart) is crucial for the development of healthy bulbs.
- Extreme heat or frost can inhibit bulb formation.
- Keeping kohlrabi plants in shade for an extended period can prevent bulb growth.
- Adequate and consistent watering is essential for the development of healthy bulbs.
Proper Spacing And Recommended Size For Harvesting Kohlrabi Bulbs
To ensure optimal growth and bulb formation in kohlrabi plants, proper spacing is essential. It is recommended to space the plants 6-9 inches apart. This spacing allows each plant to have sufficient room to develop a healthy bulb.
The recommended size for harvesting kohlrabi bulbs is when they are about 2-3 inches in diameter. At this size, the bulbs are tender and have the best texture and taste. If the bulbs become woody and cracked, it is often a result of leaving them in the ground for too long or exposing them to hot weather without adequate water.
Cracking in the bulbs can also be a sign of insufficient water or possibly an imbalance in nitrogen fertilizer. It is essential to maintain consistent watering and avoid over-fertilization to prevent cracking in the bulbs.
- Proper spacing of 6-9 inches between kohlrabi plants
- Recommended size for harvesting kohlrabi bulbs: 2-3 inches in diameter
- Bulbs becoming woody and cracked due to overexposure to heat and lack of water
- Cracking can also be caused by insufficient water or imbalanced nitrogen fertilizer.
Tips For Growing Kohlrabi From Cuttings
Growing Kohlrabi: Seeds vs. Cuttings
While growing kohlrabi from cuttings is possible, it is generally more reliable and simpler to grow them from seeds. However, if you choose to propagate kohlrabi from cuttings, here are some tips to follow:
- Start by taking cuttings with two or three leaves from a healthy kohlrabi plant.
- Place these cuttings in water until roots begin to form.
- Once the roots are a few inches long, pot up the cuttings and place them under a cold frame or cloche to protect them.
- After hardening off, plant the cuttings in the garden.
Note: Growing kohlrabi from seeds is often the preferred method as it offers better control over the plant’s growth and development.
Harvesting And Cutting Kohlrabi Stems For Optimal Growth
There are two main methods for harvesting kohlrabi stems. The first is to pull the whole plant, including the roots. The second method is to cut the stems off at the base, just above the soil line.
If you wish to continue the growth of the plant after harvesting, it is recommended to cut the skinniest part of the stem right below where it starts to widen, just above the soil line. This allows the plant to regenerate and potentially produce another bulb.
When cutting the tough stems of kohlrabi, it is advisable to use sharp and heavy-duty garden shears. These tools will make the cutting process easier and more efficient.
It is essential to note that leaving the remaining stem in the ground is only necessary if you want to save the seeds. Otherwise, it will not produce another crop. Additionally, it’s important to remember that only one kohlrabi grows per plant, so it’s crucial to harvest them before they become too large and lose their desirable flavor and texture.
Storing And Preserving Kohlrabi After Harvesting
After harvesting kohlrabi, proper storage is crucial to ensure its freshness and longevity. Kohlrabi can be stored for up to three weeks if stored correctly.
The best way to store kohlrabi is to place it in a sealed, perforated bag in the refrigerator. This method helps maintain the freshness and prevents moisture loss, which can lead to the deterioration of the vegetable.
Additionally, kohlrabi can also be preserved for later use by freezing it. To freeze kohlrabi, it is recommended to blanch it first by placing it in boiling water for a few minutes, then immediately transferring it to an ice bath to stop the cooking process. Once blanched, the kohlrabi can be placed in freezer-safe containers or bags and stored in the freezer until needed.
By following these storage and preservation methods, you can enjoy kohlrabi for an extended period even after harvesting.
In conclusion, while kohlrabi does not grow back after being cut, the bottom part of the stem can be left in the ground to allow for regeneration. It is essential to harvest kohlrabi when it reaches the recommended size of 2-3 inches in diameter for optimal texture and taste. Proper spacing, watering, and protection from extreme weather conditions are vital for healthy bulb growth. By following these guidelines, you can enjoy the nutritious and versatile kohlrabi in various culinary creations.

Frequently Asked Questions
Can you harvest kohlrabi more than once?
Yes, kohlrabi can be harvested multiple times if the bottom part of the stem is left in the ground. Although it is considered a biennial plant, leaving the stem intact allows for regrowth, ensuring the possibility of multiple harvests. However, it is crucial to note that in its second year, the kohlrabi plant will divert its energy towards flowering and seed production rather than generating another edible stem.
How long does kohlrabi last after picking?
Once harvested, kohlrabi can remain fresh for a considerable amount of time if stored properly. After being washed and having its leaf stems removed, kohlrabi can be stored in the refrigerator for several weeks. To further extend its storage life, it is recommended to place the kohlrabi in sealed perforated plastic bags. As a precautionary measure, it is advisable to keep kohlrabi away from raw meat and meat juices to prevent cross-contamination.
What happens if kohlrabi is left to grow too long?
If left to grow too long, kohlrabi transforms from a tender and flavorful vegetable into a tough and unpleasant experience. The bulb becomes woody and bitter, resulting in a less enjoyable eating experience. This is particularly true for spring-planted kohlrabi harvested in summer, as they are more likely to become fibrous if over-matured. Therefore, it is crucial to harvest kohlrabi at the right time to fully appreciate its delicious, crisp texture and mild flavor.
How long will kohlrabi keep?
When properly stored in the refrigerator, kohlrabi with its leaves attached can maintain its freshness for up to 4 weeks. However, if the leaves are removed, the kohlrabi can last for a slightly extended period of 2 to 3 months. Placing the kohlrabi in a perforated plastic bag within the vegetable crisper section helps to maintain its quality and texture during storage.
