Start your plants indoors about four to six weeks before you plan to put them outside.

You can have a continuous crop if you plant your kohlrabi every two to three weeks. Make sure to place the seeds ¼ to ½ inch deep into the soil about 2 to 5 inches apart if planting seeds directly outside. Also, when growing kohlrabi, keep the soil well watered or you'll end up with tough,woody stemmed plants

After four to six weeks, plant the baby plants outdoors in well drained, rich soil. Growing kohlrabi is most successful in cooler weather. The early crops started indoors and then transplanted outdoors will provide you with a nice crop.

Just as some plants work well together, some plants do not. Aphids and flea beetles are pests that are attracted to kohlrabi as are cabbage worms and loopers. Thus, it wouldn’t be a good idea to group members of the cabbage family together with kohlrabi. It would just give more fodder to these pests.
