Growing Kohlrabi: A Beginner’s Guide to This Unusual Veggie
Hey there, fellow gardening enthusiasts! Ever heard of kohlrabi? It’s that quirky-looking vegetable that resembles a spaceship or a turnip from another planet. But don’t let its appearance fool you – kohlrabi is incredibly delicious and surprisingly easy to grow at home. I’m going to walk you through everything you need to know to cultivate your own crop of these crunchy, sweet delights.
What is Kohlrabi, Anyway?
Before we dive into the how-to, let’s talk about what kohlrabi actually is. It’s a member of the cabbage family, but instead of forming a head like cabbage, it develops a swollen stem just above the ground. This stem is the part we eat, and it tastes like a cross between a turnip and a cabbage, with a slightly sweeter, milder flavor. 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 variety that matures quickly and produces pale green bulbs.
- Early Purple Vienna: Similar to the white variety, but with a beautiful purple skin. The flesh is still white.
- Grand Duke: A hybrid variety known for its large size and excellent flavor.
- Kossak: Another large hybrid variety that’s resistant to bolting (going to seed prematurely).
I personally love growing both the Early White and Early Purple Vienna varieties 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 2-3 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 spring kohlrabi indoors to get a head start, especially if I’m aiming for an early harvest.
Where to Plant
* Sunlight: Kohlrabi needs at least 6 hours of sunlight per day.
* Soil: It prefers well-drained, fertile soil with a pH between 6.0 and 7.5. Amend your soil with compost or other organic matter to improve drainage and fertility.
I always make sure my kohlrabi patch gets plenty of sunshine and that the soil is nice and loose.
How to Plant
1. Starting Seeds Indoors:
* Fill seed trays or small pots with seed-starting mix.
* Sow seeds about ¼ inch deep.
* Water gently and keep the soil consistently moist.
* Place the trays in a warm location (around 70°F) or use a heat mat to speed up germination.
* Once the seedlings emerge, provide them with plenty of light. A grow light works wonders!
* Harden off the seedlings by gradually exposing them to outdoor conditions for a week before transplanting.
2. Direct Sowing Seeds Outdoors:
* Prepare the soil by removing any weeds and rocks.
* Sow seeds about ½ inch deep and 1-2 inches apart in rows.
* Water gently and keep the soil consistently moist.
* Once the seedlings emerge, thin them to 4-6 inches apart.
Caring for Your Kohlrabi Plants
Once your kohlrabi plants are in the ground, it’s time to provide them with the care they need to thrive.
Watering
Kohlrabi needs consistent moisture to develop properly. Water deeply and regularly, especially during dry spells. Aim for about 1 inch of water per week. I like to use a soaker hose to deliver water directly to the roots.
Fertilizing
Feed your kohlrabi plants with a balanced fertilizer every 2-3 weeks. You can use a liquid fertilizer or a granular fertilizer. Follow the instructions on the fertilizer package. I often use a fish emulsion fertilizer, which is a great organic option.
Weeding
Keep the area around your kohlrabi plants free of weeds. Weeds compete with your plants for nutrients and water. Hand-pull weeds regularly or use a hoe to cultivate the soil. Mulching around the plants can also help suppress weeds.
Pest and Disease Control
Kohlrabi can be susceptible to a few pests and diseases. Here are some common problems and how to deal with them:
* Cabbage Worms: These green caterpillars can devour the leaves of your kohlrabi plants. Hand-pick them off or use a biological insecticide like Bacillus thuringiensis (Bt).
* Flea Beetles: These tiny beetles can create small holes in the leaves. Cover your plants with row covers to prevent flea beetles from reaching them.
* Aphids: These small, sap-sucking insects can weaken your plants. Spray them off with a strong stream of water or use insecticidal soap.
* Clubroot: This fungal disease can cause the roots of your kohlrabi plants to swell and distort. Prevent clubroot by practicing crop rotation and maintaining a soil pH above 7.0.
I always keep a close eye on my kohlrabi plants for any signs of pests or diseases. Early detection is key to preventing serious problems.
Harvesting Your Kohlrabi
The best part of growing kohlrabi is, of course, harvesting and eating it!
When to Harvest
Harvest your kohlrabi when the bulbs are about 2-3 inches in diameter. This is usually about 50-60 days after planting. Don’t let the bulbs get too large, as they can become tough and woody.
How to Harvest
1. Use a sharp knife or garden shears to cut the bulb from the stem just above the soil line.
2. Remove the leaves from the bulb. You can eat the leaves, too! They taste similar to collard greens.
I always harvest my kohlrabi when it’s young and tender. The smaller bulbs are much sweeter and more flavorful.
Storing Your Kohlrabi
Kohlrabi can be stored in the refrigerator for several weeks. Remove the leaves and store the bulbs in a plastic bag. You can also freeze kohlrabi. Blanch the bulbs for 2-3 minutes, then cool them in ice water before freezing.
Enjoying Your Kohlrabi Harvest
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 into thin strips or cubes. Add it to salads, slaws, or veggie platters.
* Cooked: Steam, boil, roast, or stir-fry kohlrabi. It’s delicious in soups, stews, and side dishes.
* Pickled: Pickle kohlrabi for a tangy and refreshing treat.
I love eating kohlrabi raw in salads. It adds a nice crunch and a slightly sweet flavor. I also enjoy roasting it with other root vegetables.
Troubleshooting Common Kohlrabi Problems
Even with the best care, you might encounter a few challenges when growing kohlrabi. Here are some common problems and how to fix them:
* Bulbs are not forming: This could be due to insufficient sunlight, poor soil, or lack of water. Make sure your plants are getting enough sunlight, amend your soil with compost, and water regularly.
* Bulbs are cracking: This is usually caused by inconsistent watering. Water deeply and regularly, especially during dry spells.
* Bulbs are tough and woody: This is usually because the bulbs were allowed to grow too large before harvesting. Harvest your kohlrabi when the bulbs are 2-3 inches in diameter.
* Plants are bolting (going to seed prematurely): This can be caused by hot weather or stress. Choose bolt-resistant varieties and provide your plants with shade during hot weather.
