Growing Kohlrabi Like a Pro: From Seed to Table in Record Time!
Hey there, fellow gardening enthusiasts! I’m so excited to share my secrets for growing kohlrabi – that quirky, delicious, and surprisingly fast-growing vegetable – in your own backyard. Forget waiting ages for a harvest; with these tips and tricks, you’ll be enjoying fresh kohlrabi in no time!
Understanding Kohlrabi’s Needs
Before we dive into the nitty-gritty, let’s quickly cover what kohlrabi needs to thrive. Think of it as setting the stage for success!
* Sunlight: Kohlrabi loves sunshine! Aim for at least 6 hours of direct sunlight per day. The more, the merrier!
* Soil: Well-draining, fertile soil is key. Kohlrabi isn’t too picky, but it appreciates soil rich in organic matter.
* Water: Consistent moisture is crucial, especially during bulb development. Think evenly moist, not soggy.
* Temperature: Kohlrabi prefers cooler temperatures, ideally between 60-75°F (15-24°C). This makes it a perfect spring or fall crop.
* Fertilizer: A balanced fertilizer will give your kohlrabi a boost, especially during its early growth stages.
Choosing the Right Variety
Not all kohlrabi are created equal! Some varieties mature faster than others. Here are a few of my favorites for a quick harvest:
* Early White Vienna: This is a classic choice, known for its early maturity and mild flavor.
* Early Purple Vienna: Similar to the white variety, but with a beautiful purple hue.
* Quickstar: As the name suggests, this variety is super speedy, often ready in just 40-45 days.
* Kolibri: A vibrant purple variety that’s both fast-growing and visually appealing.
Starting from Seed: The Fast Track to Kohlrabi
While you can buy kohlrabi seedlings, starting from seed gives you more control and often results in a quicker harvest. Here’s how I do it:
Phase 1: Indoor Seed Starting (Optional, but Recommended)
Starting seeds indoors gives you a head start, especially if you live in an area with a short growing season.
1. Gather Your Supplies: You’ll need seed starting trays or small pots, seed starting mix (not regular potting soil!), kohlrabi seeds, a spray bottle, and a heat mat (optional, but helpful).
2. Sow the Seeds: Fill your trays or pots with seed starting mix. Moisten the mix with the spray bottle – it should be damp, not soaking wet. Sow 2-3 kohlrabi seeds per cell or pot, about ¼ inch deep.
3. Provide Warmth and Light: Place the trays or pots on a heat mat (if using) and under grow lights or in a sunny window. Kohlrabi seeds germinate best at temperatures between 65-75°F (18-24°C).
4. Keep Moist: Mist the soil regularly to keep it consistently moist. Don’t let it dry out!
5. Thin Seedlings: Once the seedlings emerge (usually in 5-7 days), thin them to one strong seedling per cell or pot. Snip off the weaker seedlings at the soil line with scissors.
Phase 2: Transplanting Seedlings (or Direct Sowing)
Whether you started seeds indoors or are direct sowing, this is where the magic happens in the garden!
1. Prepare the Garden Bed: Choose a sunny spot in your garden and amend the soil with compost or well-rotted manure. This will provide essential nutrients and improve drainage.
2. Harden Off Seedlings (If Transplanting): If you started seeds indoors, you’ll need to “harden them off” before transplanting. This means gradually exposing them to outdoor conditions over a week or so. Start by placing them outside for a few hours each day, gradually increasing the time until they can stay outside all day and night.
3. Transplant or Direct Sow:
* Transplanting: Dig small holes in the prepared garden bed, spacing them about 6-8 inches apart. Gently remove the seedlings from their trays or pots and plant them in the holes, making sure the top of the root ball is level with the soil surface. Water thoroughly.
* Direct Sowing: Sow kohlrabi seeds directly into the prepared garden bed, about ¼ inch deep and 1-2 inches apart. Once the seedlings emerge, thin them to 6-8 inches apart.
4. Water Regularly: Keep the soil consistently moist, especially during the first few weeks after transplanting or direct sowing.
Supercharging Growth: My Secret Weapons
Okay, now for the real secrets to growing kohlrabi fast! These are the techniques I use to give my plants an extra boost.
1. Fertilizing for Speed
Kohlrabi are heavy feeders, meaning they need plenty of nutrients to grow quickly.
* Pre-Planting: Incorporate a slow-release fertilizer into the soil before planting. I like to use a balanced organic fertilizer with an NPK ratio of around 10-10-10.
* Side-Dressing: Once the plants are established (about 2-3 weeks after transplanting or direct sowing), side-dress them with a nitrogen-rich fertilizer. This will encourage leafy growth and bulb development. I use fish emulsion or blood meal, but you can also use a synthetic nitrogen fertilizer. Be careful not to over-fertilize, as this can lead to leggy growth and poor bulb formation. Follow the instructions on the fertilizer label.
* Foliar Feeding: For an extra boost, I sometimes use a foliar feed. This involves spraying the leaves with a diluted fertilizer solution. The plants absorb the nutrients directly through their leaves, providing a quick and effective boost. I use seaweed extract or a diluted fish emulsion solution.
2. Watering Wisely
Consistent moisture is crucial for fast kohlrabi growth.
* Deep Watering: Water deeply and infrequently, rather than shallowly and frequently. This encourages the roots to grow deeper, making the plants more drought-tolerant.
* Mulching: Apply a layer of mulch around the plants to help retain moisture and suppress weeds. I use straw, wood chips, or shredded leaves.
* Avoid Overwatering: While kohlrabi needs consistent moisture, it doesn’t like to be waterlogged. Overwatering can lead to root rot and other problems. Make sure the soil is well-draining.
3. Pest and Disease Control: Staying One Step Ahead
Pests and diseases can slow down kohlrabi growth, so it’s important to be proactive.
* Row Covers: Use row covers to protect young plants from pests like flea beetles and cabbage moths.
* Handpicking: Regularly inspect your plants for pests and handpick them off. This is especially effective for larger pests like cabbage worms.
* Insecticidal Soap: If you have a serious pest infestation, use insecticidal soap. This is a safe and effective way to control many common garden pests.
* Crop Rotation: Rotate your crops each year to prevent soilborne diseases from building up.
* Good Air Circulation: Ensure good air circulation around your plants to prevent fungal diseases. Space them properly and prune away any overcrowded leaves.
4. Strategic Harvesting: Knowing When to Pick
Harvesting kohlrabi at the right time is crucial for optimal flavor and texture.
* Harvest Early: Kohlrabi is best harvested when the bulbs are small and tender, about 2-3 inches in diameter. Larger bulbs can become tough and woody.
* Check for Size: Regularly check the size of the bulbs. You can gently feel them to determine their size.
* Harvesting Technique: To harvest, simply cut the bulb from the stem with a sharp knife.
* Succession Planting: Plant kohlrabi seeds every 2-3 weeks for a continuous harvest throughout the growing season.
