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 a low-nitrogen 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 low-nitrogen 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:

Plant Adzuki Beans in the spring after all danger of frost has passed and the soil temperature reaches at least 60F. For fall crops, direct sow seeds or transplant seedlings outdoors 10-12 weeks before the first frost. To plant, make holes 1 inch deep and spaced 3 inches apart down the rows of raised beds. Plant 1-2 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.

Planting Depth:	1 inch
Within-Row Spacing:	3 inches
Between-Row Spacing:	18-24 inches

Care During the Season:

Watering: Water the plants deeply, soaking the soil to a depth of 6-8 inches, once to twice a week. If there is no rainfall, water 3-4 times a week. Water especially during flowering and pod formation. Sandy soils may need to be watered more often than heavy clay soils. Mulching around plants can help retain moisture.

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 plants start forming pods, you may optionally apply 2 tablespoons of a low-nitrogen fertilizer around each hole, or 1-2 pounds per 100 square feet, 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:

Adzuki beans are ready to harvest when the pods are fully mature and have dried on the plant. This typically occurs about 90-120 days after planting, depending on the growing conditions. Look for pods that are brown, dry, and brittle, indicating the beans inside have reached maturity. If harvesting for fresh beans, pick the pods when they are plump and green, but for dried beans (the most common use), wait until the pods are completely dry. Harvest before frost, as cold weather can damage the beans. To collect, simply pull the pods from the plant and shell the beans, or pull up the entire plant to dry indoors if wet weather threatens.
