When is the best time to plant rutabagas in Iowa?
The rutabaga performs best when planted in summer for a fall crop. Sow seed at a depth of 1/4 to ½ inch from June 15 to July 15 in Iowa. Rows should be spaced 18 to 24 inches apart. Thin the planting within a few weeks of germination. After thinning, rutabaga seedlings should be spaced 6 inches apart.
‘American Purple Top’ and ‘Laurentian’ are suggested rutabaga varieties for home gardens. Both varieties produce globe-shaped, light yellow roots with purple tops. Their flesh is yellow.
