Growing Kohlrabi: From Seed to Table – A DIY Guide
Hey there, fellow gardening enthusiasts! I’m so excited to share my experience and tips on growing kohlrabi. This quirky vegetable, often called a “German turnip,” is surprisingly easy to grow and incredibly versatile in the kitchen. Don’t let its unusual appearance intimidate you; with a little guidance, you’ll be harvesting delicious kohlrabi in no time.
Understanding Kohlrabi
Before we dive into the nitty-gritty, let’s talk a bit about what kohlrabi actually is. It’s a member of the Brassica family, which also includes cabbage, broccoli, and kale. The part we eat is the swollen stem, which grows above ground. It comes in green, purple, and white varieties, and the taste is often described as a mild, sweet turnip or a slightly peppery cabbage.
Planning Your Kohlrabi Garden
Success with kohlrabi starts with proper planning. Here’s what you need to consider:
* Timing is Key: Kohlrabi thrives in cool weather. Plant it in early spring for a summer harvest or in late summer for a fall harvest. Avoid planting during the hottest months, as high temperatures can cause the kohlrabi to become tough and woody.
* Sunlight: Kohlrabi needs at least 6 hours of sunlight per day. Choose a location in your garden that receives plenty of sun.
* Soil: Well-drained, fertile soil is essential. Kohlrabi prefers a slightly acidic to neutral pH (6.0-7.5).
* Variety Selection: There are several kohlrabi varieties to choose from. ‘Early White Vienna’ and ‘Early Purple Vienna’ are popular choices for early harvests. ‘Grand Duke’ is a larger, later-maturing variety. I personally love the ‘Purple Vienna’ for its beautiful color and mild flavor.
* Spacing: Give your kohlrabi plants enough space to grow. Space them 6-8 inches apart in rows that are 12-18 inches apart.
Starting Kohlrabi from Seed
I usually start my kohlrabi seeds indoors about 4-6 weeks before the last expected frost. This gives them a head start and ensures a longer growing season.
1. Prepare Your Seed Starting Mix: Use a seed starting mix that is light and well-draining. I like to mix equal parts peat moss, vermiculite, and perlite.
2. Sow the Seeds: Fill your seed starting trays or pots with the mix and sow the seeds about ¼ inch deep. I usually plant 2-3 seeds per cell to increase the chances of germination.
3. Water Gently: Water the soil gently to moisten it, being careful not to dislodge the seeds.
4. Provide Warmth and Light: Place the trays in a warm location (around 70-75°F) and provide plenty of light. A heat mat can help speed up germination. If you don’t have a sunny window, use grow lights.
5. Thin Seedlings: Once the seedlings emerge (usually in 5-7 days), thin them to one plant per cell. Choose the strongest, healthiest seedling and snip off the others at the soil line.
6. Harden Off: Before transplanting the seedlings outdoors, you’ll need to harden them off. This means gradually exposing them to outdoor conditions over a period of 7-10 days. Start by placing them in a sheltered location for a few hours each day, gradually increasing the amount of time they spend outdoors.
Transplanting Kohlrabi Seedlings
Once the danger of frost has passed and your seedlings are hardened off, it’s time to transplant them into your garden.
1. Prepare the Soil: Amend the soil with compost or well-rotted manure to improve its fertility and drainage.
2. Dig Holes: Dig holes that are slightly larger than the root balls of the seedlings, spacing them 6-8 inches apart.
3. Transplant Carefully: Gently remove the seedlings from their trays or pots and place them in the holes. Make sure the top of the root ball is level with the soil surface.
4. Fill and Water: Fill the holes with soil and gently firm it around the plants. Water thoroughly.
5. Mulch: Apply a layer of mulch around the plants to help retain moisture, suppress weeds, and regulate soil temperature. I like to use straw or shredded leaves.
Direct Sowing Kohlrabi Seeds
If you prefer, you can also direct sow kohlrabi seeds directly into your garden. This is a good option if you live in an area with a longer growing season.
1. Prepare the Soil: As with transplanting, amend the soil with compost or well-rotted manure.
2. Sow the Seeds: Sow the seeds about ½ inch deep, spacing them 1-2 inches apart.
3. Water Gently: Water the soil gently to moisten it.

Caring for Your Kohlrabi Plants
Once your kohlrabi plants are established, they’re relatively low-maintenance. Here’s what you need to do to keep them healthy and productive:
* Watering: Kohlrabi needs consistent moisture, especially during hot, dry weather. Water deeply whenever the top inch of soil feels dry.
* Fertilizing: Fertilize your kohlrabi plants every 2-3 weeks with a balanced fertilizer. I like to use a liquid fertilizer diluted to half strength.
* Weeding: Keep the area around your kohlrabi plants free of weeds. Weeds can compete with the kohlrabi for nutrients and water.
* Pest Control: Kohlrabi can be susceptible to pests such as cabbage worms, aphids, and flea beetles. Inspect your plants regularly and take action if you see any signs of infestation. I prefer to use organic pest control methods, such as insecticidal soap or neem oil.
* Bolting Prevention: Bolting (premature flowering) can occur if kohlrabi is exposed to prolonged periods of hot weather. To prevent bolting, provide shade during the hottest part of the day and ensure consistent watering.
Harvesting Kohlrabi
The key to delicious kohlrabi is harvesting it at the right time. You want to harvest the bulbs when they are about 2-3 inches in diameter. Larger bulbs can become tough and woody.
1. Check the Size: Regularly check the size of the kohlrabi bulbs.
2. Harvest Carefully: Use a sharp knife to cut the bulb from the stem, leaving about an inch of stem attached.
3. Remove Leaves: Remove the leaves from the bulb. The leaves are also edible and can be cooked like spinach or kale.
4. Store Properly: Store kohlrabi bulbs in the refrigerator for up to several weeks.
Enjoying Your Kohlrabi Harvest
Kohlrabi is incredibly versatile in the kitchen. You can eat it raw, cooked, or pickled.
* Raw: Peel the bulb and slice it thinly. It’s great in salads, slaws, or as a crunchy snack.
* Cooked: You can steam, boil, roast, or stir-fry kohlrabi. It’s delicious in soups, stews, and gratins.
* Pickled: Pickled kohlrabi is a tangy and refreshing treat.
My favorite way to enjoy kohlrabi is to roast it with olive oil, salt, pepper, and a sprinkle of parmesan cheese. It’s simple, delicious, and highlights the natural sweetness of the vegetable.
Troubleshooting Common Kohlrabi Problems
Even with the best planning, you might encounter some problems while growing kohlrabi. Here are a few common issues and how to address them:
* Splitting Bulbs: Splitting can occur if the plants experience inconsistent watering. Ensure consistent moisture levels, especially during dry periods.
* Tough or Woody Bulbs: This is usually caused by harvesting the bulbs too late or by growing them in hot weather. Harvest the bulbs when they are young and tender, and provide shade during hot weather.
* Pest Infestations: As mentioned earlier, kohlrabi can be susceptible to pests. Regularly inspect your plants and take action if you see any signs of infestation.
Advanced Kohlrabi Growing Techniques
If you’re feeling adventurous, here are a few advanced techniques to try:
* Succession Planting: Plant kohlrabi every 2-3 weeks to ensure a continuous harvest throughout the growing season.
* Companion Planting: Plant kohlrabi with companion plants such as dill, chamomile, and mint to attract beneficial insects and deter pests.
