INTRODUCING KOHLRABI SEEDS

Kohlrabi, with its peculiar shape, is a nutritionally rich vegetable high in vitamin C, fiber, and potassium, and is often eaten raw in salads. It is also easy to cook and adds a delicious flavor to your dishes. Kohlrabi is native to Europe but has since spread worldwide. Kohlrabi can be cultivated successfully in USDA hardiness zones 2 through 11, growing in cold easily.

PLANTING KOHLRABI SEEDS

Start indoors 3-4 weeks before transplanting outside 6-8 inches apart or sow the kohlrabi seeds directly into the garden bed. For a harvest in spring, 4 to 6 weeks before the last frost is ideal, or they can be planted in late summer for a fall crop. Plant seeds 1/4 inch deep and keep evenly moist. Kohlrabi germinates best in cool soil and seedlings can even handle light frost. It will usually sprout in 7-14 days.

MAINTAINING KOHLRABI PLANTS

Kohlrabi is mostly straightforward when it comes to care. Consistent moisture is necessary for tender bulbs, so regular watering is advised. A layer of mulch will provide significant help in that regard, while also controlling the weed growth. When the bulbs reach around 3 inches in diameter, they are ready to be harvested. They can also be harvested when smaller, for a more tender texture.

Growing kohlrabi at home is easy and rewarding. It is nutritious and fun to grow, plus it tastes great! Enjoy it raw to get that crunchy texture or cook it and enjoy its tender, turnip-like flavor. Its distinctive appearance plus its quick, easy growth make it an ideal plant for introducing children to the joys of gardening (and eating their veggies)!

Frequently Asked Questions

What are heirloom seeds?

Heirloom seeds are the types of seeds your grandparents grew. These varieties have been passed down from generation to generation. They’re old reliable open-pollinated varieties that aren’t typically grown commercially. Instead, they have a rich history that predates modern breeding techniques. You can learn more about open-pollinated, heirloom, and non-GMO seeds in our Survival Garden Training blog.

How do I know my seeds are fresh?

Every seed packet includes a "packed for" date, and we germination test each seed lot before packaging to ensure you receive viable, high-quality seeds that are ready to grow.

Are your seeds chemically treated?

No, we do not pre-treat our seeds. All of our garden seeds are untreated, open-pollinated, non-GMO, and heirloom varieties. They are kept in temperature-controlled cooler storage until they are packed and shipped to keep them pest and disease-free.

Will your seeds grow in my USDA Hardiness zone?

The seeds in our collections are specifically chosen from varieties that can be successfully grown from Zone 3 to Zone 10 USDA Hardiness Zones. However, individual varieties have specific needs to thrive in different environments. Each seed pack has optimal temperatures for germination and instructions on seed starting. Consult local frost dates to plan your garden and get the most out of your seeds.

What is the shelf life of these garden seeds?

Most seeds remain viable for 3 to 5 years or longer when stored properly. Check your seed packet for specific varieties. For best results, keep your seeds in a cool, dry place away from direct sunlight and moisture. Store them in an airtight container in a consistent temperature environment—a refrigerator or cool basement works well. Proper storage helps maintain germination rates and extends seed life well beyond the packed date.

Where are Survival Garden Seeds sourced?

The majority of our seeds are sourced in the United States, with a few exceptions when the seed is difficult to source domestically. Whenever we do have to source outside of the US, we ensure our seeds are safe to grow, non-GMO, heirloom varieties that meet our standards for germination and reliability.
