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

Planting:

Scallions grows best in cool weather, thriving in 55F-75F soil temperatures. Plant in the spring as soon as the soil can be worked, about 2-4 weeks before the last frost in spring. Optionally, start indoors 8-10 weeks before the last frost in Spring. Harden off, then divide clumps 6 inches apart outdoors when the soil reaches 55F. For fall crops, direct sow seeds outdoors 2-4 weeks before the first frost. Established Scallions can be mulched and overwintered. To plant, make holes 1/4 inch deep and spaced 1-2 inches apart down the rows of raised beds. Plant 5 seeds per hole. Cover seeds thinly with soil and water after planting. Or, broadcast seeds and separate clumps to the desired spacing when seedlings come up. If you want a continuous supply throughout the fall, you can sow seeds every 2-3 weeks.

Planting Depth:	1/4 inch
Within-Row Spacing:	1-2 inches
Between-Row Spacing:	12-18 inches

Care During the Season:

Watering: Water the plants, soaking the soil to a depth of 6-8 inches, once a week. If there is no rainfall, water 2 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: You may optionally apply a light or diluted dressing of a complete fertilizer once a month during the growing season, 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:

Scallions can be harvested 30 to 60 days after planting, depending on the desired size. They can be harvested at any stage once they reach at least 6 to 12 inches tall and have a pencil-thin diameter. For a continuous harvest, carefully pull individual plants from the soil, or use scissors to cut the greens just above the soil line, allowing the bulbs to regrow. To store, rinse off excess soil and keep them in a plastic bag in the refrigerator.
