What's the secret for growing big kohlrabi?
What kind of fertilizer should I use? Should I apply a mulch to conserve moisture? I'm planning to use kelp and a 2-2-2 organic fertilizer. |

Why do you want to grow big ones? I have found the big ones are woody & tough--much prefer about the size of a small lemon.

One of my fellow community gardeners grows huge kohlrabi using seed from Germany. Iirc there's a variety called Giganti/Gigante/Gigant that produces larger than usual kohlrabi.

I have to grow a purple variety...it will get woody when it grows big.
I often read to give kohlrabi a liquid fertilizer...but what kind? Which npk should I use to fertiliize kohlrabi? |

Two very large varieties I know of are Granlibakken and Superschmelz. Don't quote me on their spelling.
It was several years ago, so I don't remember which one was nice, crisp and juicy, while the other had the texture of neoprene. ![]() Gary |

I have to grow the delicatesse (blue) Kohlrabi.
I have a fertilizer with vinasse + fishemulsion, npk 5-3-4. Will that work on kohlrabi? |

The 2 giant varieties posted above will grow huge. I think I tried Super ?? A few years ago. I don't know if that's the variety a fellow market grower used, but he regularly has things nearly the size of a basketball. And they are good not woody.
If you grow the old Vienna types, yes you have to pull them when they are about tennis ball size or they will be woody. But the hybrids like Grand Duke or Winner can get to about grade school soft ball size and still be good. One trick is that they need to grow fast to be tender. Look at the spacing of the leaves. If they are just about on top of each other they will be tough. If they are nice and wide apart, they will be tender. There is a newer hybrid purple variety too but I've never tried it and don't know the name. Carol |

When I plant them in the garden, how deep can I plant them?
Untill the first real leave? |

Is there a way to see if my kohlrabi is fully grown?
They are growing pretty good. ![]() |

He's growing huge.
I fertilize him with 3 times the concentration of the fertilizer I give to my tomatoes and peppers. ![]() |
