Tagged: Kohlrabi bulbs
Hi we have been growing kohlrabi for at least 30 years , the last two the kohlrabi has grown lots of leaves and no bulbs, we tried different varities purple and green both finished the same . any suggestions.
Kohlrabi bulb formation requires more phosphorus and potassium in the soil than nitrogen. Before you plant kohlrabi again, sprinkle an organic fertilizer across the planting bed that is higher in phosphorus and potassium than nitrogen–such as 5-10-10. Avoid nitrogen rich fertilizers where you plant kohlrabi or root crops.
