Choose an area with heavy, well-draining soil that receives at least 6 hours of sunlight each day. Remove weeds, large rocks, and litter from the planting area. Leave small weeds and dead grass, they will enrich the soil when turned under. Spade or till the soil 8-12 inches deep. Loosening the soil will help the plant establish strong roots.
Plants grow best in soil with lots of organic matter. You may optionally add fertilizer or organic material such as compost, leaves, or rotted hay to mix into the soil at this point. For small gardens, scatter 2-3 tablespoons of fertilizer evenly and work into the top 2-3 inches of soil for each hill or 2 foot by 2 foot planting area. For larger gardens, scatter 2-3 pounds of a complete fertilizer for each 100 square feet of planting area. Work fertilizer or organic material into the soil and leave the surface smooth.
Form rows of soil beds 4-6 inches high and at least 12 inches apart. This formation of ridges will help with drainage. If planting in a garden bed, roots can be planted more densely, at a rate of 16 plants per square foot.
| Planting Depth: | 1/2 inch |
| Within-Row Spacing: | 3 inches |
| Between-Row Spacing: | 12-18 inches |
Watering: Water the plants deeply, soaking the soil to a depth of 6-8 inches, once a week. If there is no rainfall, water 2-3 times a week. Sandy soils may need to be watered more often than heavy clay soils.
Weeding: Keeping plants weed-free improves production. If plowing or hoeing, do not dig deeper than 1 inch to prevent from cutting the feeder roots.
Fertilizing: Once seedlings are established, 2-4 weeks after planting, you may optionally apply a complete fertilizer, without letting the fertilizer touch the plants. Read and follow fertilizer instructions for best application. Water plants after fertilizing.
Insecticides: Insecticides may be used to protect plants. Bt-based insecticides and sulfur are organic options that can be used for prevention. Sulfur also has fungicidal properties and helps in controlling many diseases. Before using a pesticide, read the label and follow cautions, warnings and directions.
Diseases: If spots or mold appear, treat plants with an approved fungicide. Neem oil, sulfur, and other fungicides may be used. When using fungicides always follow label directions.
Harvest parsnips after the first frost. Or, if harvesting earlier, store the harvested parsnips 2-3 weeks below 35F for best flavor. Parsnips have natural starches that enzymes will then break down into sugar when frozen, this gives the parsnips its unique earthy sweetness. Harvest parsnips by pulling from the tops until the roots separate from the soil.
