Kohlrabi Planting Information:

Kohlrabi does best in cool weather with abundant moisture to prevent the edible portion from becoming tough and woody. Plant your seeds indoors 4 to 6 weeks before setting them outside. Spring planting should occur as soon as the soil can be worked and after the last frost. Fall planting should be done in June, July, or August. Plants grow 9 - 12" tall.

Soil Requirements:

Requires fertile soil in a well-drained location in the garden. Apply mulch, grass clippings, or straw around the base of the plant.

Water Requirements:

Water well during dry and hot spells.

Fertilizer Requirements:

Use Slow Release (6 Month) Fertilizer when transplanting outdoors. Apply Miracle-Gro Liquid Fertilizer every two weeks.

Harvest Tips:

Harvest when bulbs are 3" in diameter.
