A standard winter and spring vegetable, of the easiest culture in deep soil (Fig. 311).
Parsnips are the better for the winter's freeze, although they are of good quality if taken up after the fall frosts and packed in soil, sand, or moss in the cellar.
The seed, which must be not over one year old, should be sown as early as possible in well-prepared soil, firmed with the feet or roller. As the seed germinates rather slowly, the ground often becomes crusted or baked over the seeds, in which case it should be broken and fined with a garden rake. This operation often means the success of the crop. Radish or cabbage seeds may be sown with the parsnip seed to mark the row and break the crust. One ounce of seed will sow 200 feet of drill. Thin to 6 inches apart in the row.
