Because of its turnip-like appearance, kohlrabi is sometimes misclassified as a root vegetable. Leaves stand out like little spokes on the sides and top of the edible, enlarged stem. You'll welcome not only kohlrabi's unusual shape, but also its crisp texture and wonderful, delicately sweet, nutty, and very slightly peppery. Eat it like an apple, or try it steamed, sautéed, or pickled, too! One cup contains 140% of the recommended daily allowance of vitamin C.

Only a few germinated.
Douglas G Stark from TX
Owner Response: Hi Douglas, Thank you for taking the time to share your experience. We are sorry that you saw poor germination with this seed. The ideal soil temperature range for germination of this seed is 65- 80 degrees F and because seeds are small and sown shallowly they will require regular watering which may mean more than once a day in hot climates, like TX. Rest assured, quality is very important to us and each seed lot is tested regularly to ensure germination rates exceed both federal standards and our own. A customer service agent will be with you shortly to help troubleshoot the issue.

Did not form bulbs

3 out of 5 stars Jan 16, 2021
We tried to grow people Vienna kohlrabi in our raised bed. Good germination rate, but never formed bulbs (was shaped more like broccoli stems/leaves). Maybe something off w nutrient balance?
Jill from CT
Owner Response: Hi Jill, A soil test can be quite helpful in finding nutrient imbalances. Kohlrabi can fail to create a bulb if plants are too close, there is a nutrient imbalance, or if there is too much or too little water.

Poor Germination

2 out of 5 stars May 2, 2021
I started 40 seeds indoors in 3/4" soil blocks, covered with vermiculite, on a temperature controlled heat mat at 77 degrees F. Only had 3 germinate after 10 days. Had another variety of Kholrabi sown same way, same amount, on same heat mat and only had 2 not germinate out of those 40? Not sure why.
Lance from NH
