Rutabaga Size Issues
My rutabagas ran small again this season. This was in spite of timely planting (July 1), irrigation, and thinning (4 to 6 inches.) The tops were strong. Am I lacking a specific nutrient? The variety was Joan from High Mowing Seeds.
We apologize for the delay in answering.
The variety Joan is recommended for cooler growing areas. They are part of the brassica family or cabbage family. They require 90 days to mature and do better in cooler weather, and only one crop is usually gotten per year. The recommended date to plant is 100 days before the first frost date. You may need to do a soil test to see if what the nutrient level is. Sometimes if the nitrogen level is higher, you get larger tops and smaller roots.
