Planting Instructions:

Soil Preparation:

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 18 inches apart. This formation of ridges will help with drainage.

Planting:

Dill grows best in cooler temperature, between 55F-70F. Plant Dill in the spring when the soil temperature is at least 60F, about 2-4 weeks after the last frost in spring. Transplanting Dill is not recommended as plants have long taproots. For fall crops, direct sow seeds outdoors 14 weeks before the first frost. To plant, make holes 1/2 inch deep and spaced 12-18 inches apart down the rows of raised beds. Plant 2-3 seeds per hole. If choosing to thin to the strongest plant, determine the strongest and healthiest plant, then remove all other plants, narrowing to a single plant per hole. Cover seeds thinly with soil and water after planting. If you want a continuous supply of Dill throughout the fall, you can sow seeds every 2-3 weeks.

Care During the Season:

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 to deeply to prevent from cutting the feeder roots.

Fertilizing: Dill does not require frequent fertilization. If plants are smaller than expected, you may optionally apply a light dressing of a complete fertilizer, without letting the fertilizer touch the plants. 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.

Harvesting:

Dill is best harvested when the plant reaches about 6-8 inches in height and has developed a good amount of foliage, about 40-50 days after planting. For the leaves, simply snip off the top 1/3 of the plant, cutting above a leaf node, which will encourage further growth. If you're harvesting seeds, wait until the flower heads turn brown and dry out, then cut the entire flower stalk and place it in a paper bag to finish drying. Shake the bag to collect the seeds once they're fully dried. Dill grows quickly, so frequent harvesting of the leaves will help encourage continuous growth.
