Grow Your Own Delicious Kohlrabi: A Beginner’s Guide
Hey there, fellow gardening enthusiasts! Ever wanted to try growing something a little different, something that looks like it came straight out of a sci-fi movie but tastes surprisingly delicious? Then kohlrabi is your answer! This quirky vegetable, often called a “German turnip” (though it’s not a turnip at all!), is incredibly easy to grow, even for beginners. I’m going to walk you through everything you need to know to cultivate your own kohlrabi crop, from seed to table.
What is Kohlrabi, Anyway?
Before we dive in, let’s talk 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 has a mild, slightly sweet flavor, similar to a turnip or radish, but much milder. You can eat it raw, cooked, or even pickled!
Choosing Your Kohlrabi Variety
There are several kohlrabi varieties to choose from, each with its own unique characteristics. Here are a few popular options:
* Early White Vienna: A classic, early-maturing variety with pale green bulbs. It’s known for its mild flavor and crisp texture.
* Early Purple Vienna: Similar to the white variety, but with a beautiful purple skin. The flesh is still white.
* Grand Duke: A hybrid variety that’s known for its disease resistance and uniform bulb size.
* Kossak: A giant variety that can grow to be quite large without becoming woody or tough.
* Superschmelz: Another giant variety, known for its excellent flavor and texture even when large.
I personally love growing both the Early White Vienna and Early Purple Vienna for their vibrant colors and reliable yields.
Getting Started: Planting Kohlrabi
Kohlrabi is a cool-season crop, which means it thrives in cooler temperatures. Here’s how to get your kohlrabi journey started:
When to Plant
* For a spring harvest: Start seeds indoors 4-6 weeks before the last expected frost. You can also direct sow seeds outdoors 2-4 weeks before the last frost.
* For a fall harvest: Direct sow seeds outdoors 6-8 weeks before the first expected frost.
I usually start my seeds indoors to get a head start, especially for the spring crop.
Starting Seeds Indoors
1. Gather your supplies: You’ll need seed starting trays or small pots, seed starting mix, kohlrabi seeds, and a spray bottle.
2. Fill the trays or pots with seed starting mix: Gently moisten the mix with the spray bottle. You want it damp, but not soggy.
3. Sow the seeds: Plant 2-3 seeds per cell or pot, about 1/4 inch deep.
4. Cover the seeds: Lightly cover the seeds with more seed starting mix.
5. Water gently: Use the spray bottle to gently water the seeds.
6. Provide warmth and light: Place the trays or pots in a warm location (around 70-75°F) and provide plenty of light. A sunny windowsill or a grow light will work well.
7. Keep the soil moist: Check the soil daily and water as needed to keep it moist.
8. Thin the seedlings: Once the seedlings have emerged and have a few true leaves, thin them to one plant per cell or pot. Choose the strongest seedling and snip off the others at the soil line.
Direct Sowing Seeds Outdoors
1. Prepare the soil: Choose a sunny location with well-drained soil. Amend the soil with compost or other organic matter to improve its fertility and drainage.
2. Sow the seeds: Sow the seeds directly into the soil, about 1/4 inch deep and 1-2 inches apart.
3. Water gently: Water the seeds gently to moisten the soil.
4. Keep the soil moist: Keep the soil moist until the seeds germinate.
5. Thin the seedlings: Once the seedlings have emerged and have a few true leaves, thin them to 4-6 inches apart.
Transplanting Kohlrabi Seedlings
Once your seedlings have developed a few true leaves and the weather has warmed up, it’s time to transplant them into the garden.
1. Harden off the seedlings: Before transplanting, you’ll need to harden off the seedlings. This means gradually exposing them to outdoor conditions over a period of 7-10 days. Start by placing them outdoors in a sheltered location for a few hours each day, gradually increasing the amount of time they spend outdoors.
2. Prepare the planting bed: Choose a sunny location with well-drained soil. Amend the soil with compost or other organic matter to improve its fertility and drainage.
3. Dig holes: Dig holes that are slightly larger than the root balls of the seedlings. Space the holes 4-6 inches apart.
4. Remove the seedlings from their containers: Gently remove the seedlings from their containers, being careful not to damage the roots.
5. Plant the seedlings: Place the seedlings in the holes and backfill with soil. Gently firm the soil around the base of the plants.
6. Water thoroughly: Water the seedlings thoroughly after planting.
Caring for Your Kohlrabi Plants
Kohlrabi is relatively low-maintenance, but there are a few things you can do to ensure a successful harvest.
* Watering: Kohlrabi needs consistent moisture to thrive. Water regularly, especially during dry periods. Aim for about 1 inch of water per week.
* 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.
* Mulching: Apply a layer of mulch around your kohlrabi plants to help retain moisture, suppress weeds, and regulate soil temperature.
* Pest control: Kohlrabi can be susceptible to pests such as cabbage worms and aphids. Inspect your plants regularly and take action if you see any signs of infestation. You can use insecticidal soap or neem oil to control these pests.
* Row Covers: Using row covers can help protect your young plants from pests and frost, especially early in the season.
Harvesting Your Kohlrabi
The best part! Kohlrabi is typically ready to harvest 50-60 days after planting.
* Harvest when the bulbs are 2-3 inches in diameter: This is when they’re at their most tender and flavorful. Larger bulbs can become tough and woody.
* Harvest by cutting the bulb at the soil line: Use a sharp knife to cut the bulb from the roots.
* Remove the leaves: Remove the leaves from the bulb. You can eat the leaves, too! They can be cooked like kale or spinach.
* Store the bulbs in the refrigerator: Kohlrabi bulbs can be stored in the refrigerator for several weeks.
Enjoying Your Kohlrabi
Now that you’ve harvested your kohlrabi, it’s time to enjoy it! Here are a few ideas:
* Raw: Peel the bulb and slice it thinly. Eat it as a snack or add it to salads.
* Cooked: Steam, boil, roast, or stir-fry the bulb.
* Pickled: Pickle the bulb for a tangy and refreshing treat.
* Grated: Grate the bulb and add it to coleslaw or other salads.
I personally love to roast kohlrabi with a little olive oil, salt, and pepper. It’s a simple and delicious way to enjoy this unique vegetable. I also enjoy grating it into salads for a bit of crunch and flavor.
Troubleshooting Common Kohlrabi Problems
Even with the best care, you might encounter a few problems while growing kohlrabi. Here are some common issues and how to address them:
* Bulbs are small or don’t develop: This could be due to insufficient watering, poor soil fertility, or overcrowding. Make sure to water regularly, fertilize as needed, and thin your plants to the proper spacing.
* Bulbs are tough or woody: This is usually caused by harvesting the bulbs too late. Harvest when they’re 2-3 inches in diameter.
* Plants are bolting (going to seed): This can happen if the plants are exposed to prolonged periods of hot weather. Try to plant your kohlrabi early in the spring or late in the summer to avoid the hottest temperatures.
