Getting Started with Kohlrabi Gardening: Planning, Soil Preparation, and Seed Selection

Kohlrabi is a hardy and easy-to-grow vegetable that can thrive in a variety of climates and soil types. If you’re interested in growing it in your garden, there are a few things to consider before getting started.

First, you’ll need to plan your garden space. Kohlrabi plants should be spaced about 6-8 inches (15-20 cm) apart, so make sure you have enough room for your desired number of plants. Keep in mind that it can be grown in both traditional garden beds and containers, so choose the option that works best for your space.

Next, you’ll need to prepare the soil. Kohlrabi prefers well-drained soil with a pH between 6.0 and 7.5. If your soil is too acidic, you can add lime to raise the pH. If it’s too alkaline, you can add sulfur to lower the pH. Work in some organic matter such as compost or well-rotted manure to improve soil structure and fertility.

When it comes to seed selection, look for kohlrabi varieties that are suitable for your climate and growing conditions. Some popular varieties include Early White Vienna, Purple Vienna, and Grand Duke. Make sure to choose high-quality seeds from a reputable source, and follow the planting instructions on the packet carefully.

Before planting the seeds, it’s a good idea to soak them in water for a few hours. This can help speed up germination and ensure a higher rate of success. Plant the seeds about ¼ to ½ inch (0.6-1.3 cm) deep, and keep the soil moist but not waterlogged.

In conclusion, getting started with kohlrabi gardening involves careful planning, soil preparation, and seed selection. With the right conditions and a little bit of effort, you can enjoy a bountiful harvest of this delicious and nutritious vegetable.

Planting: When, Where, and How to Plant for Optimal Growth

Kohlrabi is a versatile and easy-to-grow vegetable that can thrive in a variety of conditions. To ensure optimal growth and a bountiful harvest, it’s important to pay close attention to when, where, and how you plant it.

When to Plant

Kohlrabi is a cool-season crop that prefers temperatures between 60-65°F (15-18°C). It can be grown both in the spring and fall, depending on your location and climate.

In regions with mild winters, kohlrabi can be planted in the fall for a winter harvest. In colder regions, it’s best to plant it in the spring after the last frost. For a continuous harvest throughout the growing season, plant new seeds every 2-3 weeks.

Where to Plant

Kohlrabi is a hardy vegetable that can grow in a variety of soil types. However, it prefers well-draining, fertile soil with a pH of 6.0-7.5. Before planting, prepare the soil by adding organic matter such as compost or aged manure.

Kohlrabi prefers full sun but can also tolerate partial shade, making it a great crop for areas with less than ideal sunlight.

How to Plant

Plant kohlrabi seeds ¼-½ inch (0.6-1.3 cm) deep and 1-2 inches (2.5-5 cm) apart. If planting in rows, space rows 12-18 inches (30-45 cm) apart. Thin seedlings to 4-6 inches (10-15 cm) apart once they are 2-3 inches (5-7.6 cm) tall.

Especially when the tubers start to form, you should ensure even soil moisture and water regularly, especially in dry conditions, otherwise the tubers will become woody. Mulch around plants to conserve moisture and suppress weeds.

Kohlrabi is relatively pest-resistant but can be susceptible to cabbage worms, aphids, and flea beetles. To prevent pest problems, use row covers or insecticidal soap.

With these tips, you can successfully plant and grow kohlrabi in your garden. Happy planting!

Caring for Kohlrabi Plants: Watering, Fertilizing, and Pest Management

Once your kohlrabi plants are established, it’s important to maintain proper care and upkeep to ensure a bountiful harvest. Here are some tips for watering, fertilizing, and pest management.


Kohlrabi plants require consistent moisture to thrive, so it’s important to water them regularly. The amount of water your plants need will depend on factors such as the weather and soil conditions. As a general rule of thumb, aim to give your kohlrabi plants about an inch (2.5 cm) of water per week, either through rainfall or irrigation. Be sure to water deeply, so that the soil is moistened all the way down to the roots.


To promote healthy growth and optimal yields, it’s important to fertilize your kohlrabi plants regularly. Prior to planting, work a balanced, slow-release fertilizer into the soil. Once the plants have sprouted, you can apply a side dressing of nitrogen-rich fertilizer every three to four weeks. Avoid over-fertilizing, as this can lead to excessive leaf growth at the expense of the edible bulb.

Pest Management

Kohlrabi plants are susceptible to a number of pests, including flea beetles, cabbage loopers, and aphids. To prevent these pests from damaging your plants, it’s important to take proactive measures such as:

  • Using row covers to protect young plants from flea beetles
  • Hand-picking cabbage loopers and other caterpillars
  • Spraying the plants with insecticidal soap to control aphids

In addition to pests, kohlrabi plants can also be susceptible to diseases such as clubroot and black rot. To prevent these diseases, be sure to rotate your crops and avoid planting it in the same spot for at least three years.

Managing Common Kohlrabi Diseases and Pests: Prevention and Treatment Strategies

Kohlrabi is a hardy plant that can tolerate some pests and diseases, but like any other plant, it is susceptible to certain issues. Knowing how to prevent and treat common kohlrabi problems can help ensure a healthy and bountiful harvest.


The first step in preventing diseases and pests is to keep your kohlrabi plants healthy. This can be achieved by maintaining proper soil conditions and providing adequate nutrients and water.

It is also important to plant kohlrabi at the right time and in the right location. Planting in well-draining soil with good air circulation can prevent fungal diseases. Planting at the right time can also help prevent issues such as bolting or insect infestations.

Another important prevention strategy is crop rotation. This means planting in a different location each year to prevent the buildup of pests and diseases in the soil.


If you do encounter problems with your kohlrabi plants, there are several treatment options available. Here are some of the most common issues and how to treat them:

  • Clubroot: This fungal disease can cause stunted growth and yellowing leaves. To prevent clubroot, plant kohlrabi in well-draining soil and avoid overwatering. If you notice signs of clubroot, remove the affected plants and treat the soil with a fungicide.
  • Aphids: These tiny insects can suck the sap from kohlrabi leaves and cause wilting and yellowing. To control aphids, spray your plants with a strong jet of water or use an insecticidal soap.
  • Cabbage worms: These green caterpillars can eat holes in the leaves of the plants. To control cabbage worms, handpick them off your plants or use an insecticide.
  • Flea beetles: These small black beetles can eat small holes in the leaves of kohlrabi plants. To control flea beetles, use row covers or spray your plants with an insecticide.
  • Downy mildew: This fungal disease can cause yellowing leaves and a white or gray fuzz on the undersides of leaves. To prevent downy mildew, avoid overwatering and plant kohlrabi in well-draining soil. If you notice signs of downy mildew, remove the affected leaves and treat the remaining plant with a fungicide.


By taking the time to prevent and treat common kohlrabi diseases and pests, you can help ensure a healthy and abundant harvest. Remember to keep your plants healthy, plant at the right time and in the right location, and practice good pest and disease prevention strategies. With these steps, you’ll be able to enjoy the delicious flavor and nutritional benefits of kohlrabi for years to come

Harvesting Kohlrabi: When and How to Harvest for Best Results

Kohlrabi is a cool-season crop that can be harvested 8 to 10 weeks after planting. It’s important to harvest it at the right time to get the best taste and texture. Harvesting too early or too late can result in tough or woody Kohlrabi.

When to Harvest

Kohlrabi should be harvested when the bulb reaches about 2 to 3 inches (5 to 7.5 cm) in diameter. It’s important not to let the plants grow too large, as this can result in a tough, woody texture. If you’re unsure when to harvest, you can gently squeeze the Kohlrabi bulb. It should feel firm and solid. If it feels soft or spongy, it may be overripe.

How to Harvest

To harvest Kohlrabi, use a sharp knife or garden shears to cut the stem about 2 inches (5 cm) above the bulb. It’s important to leave some stem attached to the bulb, as this can help to prolong its shelf life. Once you’ve harvested it, remove any leaves or stems and store it in a plastic bag in the refrigerator. Kohlrabi can be stored for up to a month if kept at a temperature of 32 to 40°F (0 to 4°C).

It’s important to harvest Kohlrabi regularly to encourage new growth and prevent the bulbs from becoming too large. If you notice any signs of disease or pest infestation, it’s best to harvest immediately and dispose of it to prevent the spread of disease to other plants in your garden.

In conclusion, harvesting Kohlrabi is an easy process as long as you know when to harvest and how to do it properly. Remember to keep an eye on your Kohlrabi and harvest it when it’s the right size for the best taste and texture.

Storing and Preserving Kohlrabi: Tips for Keeping Your Harvest Fresh

Kohlrabi, the versatile and nutritious vegetable, is a favorite among many gardeners. With its crisp texture and slightly sweet, earthy flavor, it’s no surprise why so many people choose to cultivate it in their gardens. However, once harvested, preserving and storing kohlrabi can pose a challenge. In this chapter, we’ll provide some tips for ensuring your kohlrabi remains fresh and delicious for as long as possible.

The first and foremost thing to keep in mind when storing kohlrabi is the importance of keeping it dry. Excess moisture can quickly lead to spoilage and rot, so it is crucial to store your kohlrabi in a dry place. One option is to wrap each bulb in a dry paper towel and place it in a perforated plastic bag in the crisper drawer of your refrigerator. This will help absorb any moisture and keep your kohlrabi fresh for up to four weeks.

Alternatively, you can store kohlrabi in a cool, dry place outside of the refrigerator. A root cellar or a cool basement is ideal for this purpose. Thoroughly clean the bulbs before storing them and remove any damaged or wilted leaves. Afterward, place them in a shallow container filled with moist sand or sawdust. This will help keep them cool and prevent them from drying out.

If you find yourself with a surplus of kohlrabi and cannot use it within a few weeks, consider preserving it for future use. Blanching and freezing is an easy option. First, peel and slice the kohlrabi into 1/4 inch (0.6 cm) thick pieces, then blanch them in boiling water for 2-3 minutes, and finally, plunge them into ice water to halt the cooking process. Once cooled, drain the kohlrabi well and place it in a freezer-safe container. It can remain in the freezer for up to eight months.

For those who enjoy pickled vegetables, pickling kohlrabi is another option. Slice it into thin rounds or matchsticks and pack them into a clean, sterilized jar. In a separate saucepan, combine equal parts water and vinegar, along with sugar, salt, and any desired spices. Bring the mixture to a boil and pour it over the kohlrabi in the jar. Seal the jar and let it sit at room temperature for a day or two before transferring it to the refrigerator. Your pickled kohlrabi will be ready to enjoy in just a few days.

In conclusion, storing and preserving kohlrabi need not be daunting. With a few simple tips and tricks, you can keep your harvest fresh and flavorful for months. Remember to keep the kohlrabi dry, store it in a cool place, and consider freezing or pickling it for later use.
