How big do giant kohlrabi get?

Giant kohlrabi, also known as Kohlrabi Gigant, can reach impressive sizes when given the right growing conditions. This variety of kohlrabi takes around 60-90 days to mature and can grow to epic, mammoth proportions. The bulbs of this kohlrabi are the largest among all varieties, reaching up to 10 inches in diameter and weighing up to 10 pounds!

The size of giant kohlrabi is truly remarkable and can make a stunning addition to any garden or vegetable patch. When fully grown, these kohlrabi bulbs are a beautiful light green color, adding a vibrant touch to your garden.

To achieve such large sizes, it is important to provide the kohlrabi plants with optimal growing conditions. Here are a few tips to help you grow giant kohlrabi:

1. Soil preparation: Kohlrabi plants thrive in well-drained, fertile soil. Prepare the soil by adding organic matter such as compost or well-rotted manure to improve its nutrient content and drainage.

2. Spacing: Give each kohlrabi plant enough space to spread its roots and grow. Plant the seeds or seedlings at least 12-18 inches apart to allow for proper development.

3. Sunlight: Kohlrabi plants require full sun to grow well. Choose a location in your garden that receives at least 6-8 hours of direct sunlight per day.

4. Watering: Keep the soil consistently moist but not waterlogged. Regular watering is essential, especially during dry periods, to ensure proper growth and prevent the kohlrabi bulbs from becoming woody.

5. Fertilization: Apply a balanced fertilizer, high in nitrogen, phosphorus, and potassium, to promote healthy growth. Follow the instructions on the fertilizer package for application rates and timings.

6. Pest and disease control: Monitor your plants regularly for any signs of pests or diseases. Common pests that can affect kohlrabi include aphids, cabbage worms, and flea beetles. Use organic pest control methods or insecticidal soaps to keep them at bay.

7. Harvesting: Giant kohlrabi bulbs are ready to be harvested when they reach their maximum size, usually around 60-90 days after planting. Use a sharp knife or garden shears to cut the bulb from the stem just above the ground level. The bulbs should be firm and have a tender, buttery texture.

Personal Experience: I have grown giant kohlrabi in my own garden, and it was truly a sight to behold. The plants started off as small seedlings, and over time, they grew larger and larger. I was amazed at how quickly they reached their enormous size. When I finally harvested the bulbs, they were incredibly large and delicious. The taste was mild and slightly sweet, making them a versatile vegetable for cooking and eating raw in salads.

Giant kohlrabi can grow to impressive sizes, with bulbs reaching up to 10 inches in diameter and weighing up to 10 pounds. By providing the right growing conditions, including proper soil preparation, sunlight, watering, and pest control, you can cultivate these magnificent kohlrabi plants in your own garden. Enjoy the process of watching them grow and savor the delicious and tender bulbs when it’s time for harvest.
