November 28, 2025 •

4 min read

According to agricultural research, amaranth leaves can be effectively dried to a low moisture content of around 4–10% for extended shelf life, confirming that amaranth does dry well. Both the leaves and seeds can be successfully preserved, as can the vibrant flower plumes for decorative purposes.

Quick Summary

Both amaranth leaves and seeds can be effectively dried for long-term storage, while its distinctive flower plumes are excellent for dried floral arrangements. Proper drying techniques depend on the plant part, but success relies on achieving a low moisture content to prevent spoilage. Key methods include air drying, dehydrating, and oven drying.

Key Points

Yes, Amaranth Dries Well: Both the nutritious leaves and protein-rich seeds of the amaranth plant can be successfully dried for long-term storage and use.
Leaves Require Controlled Drying: To prevent mold and preserve color, amaranth leaves should be dried in a dehydrator or a low-temperature oven, or air-dried in a warm, shady spot with good air circulation.
Drying Amaranth Seeds is a Multi-Step Process: Harvesting the seed heads, curing them by hanging, and then threshing and winnowing are necessary steps for a clean, dry seed yield.
Amaranth Flowers are Ideal for Dried Arrangements: The colorful, velvety plumes of amaranth are perfect for dried floral crafts and maintain their form well with proper air drying.
Proper Storage Prevents Spoilage: Store all dried amaranth products in airtight containers in a cool, dark, and dry place to prevent moisture absorption and keep them fresh.
Avoid Direct Sunlight: Exposing amaranth leaves and flowers to direct sun during the drying process will cause them to lose their vibrant color.
Watch Out for Mold: The most common mistake is not drying amaranth completely. Ensure all parts are bone-dry before sealing them in containers.

Drying Amaranth Leaves for Culinary Use

When it comes to drying amaranth leaves for consumption, proper preparation is key to preserving color and flavor. The process ensures you can enjoy this nutritious green long after the growing season has ended. A key step is pre-treatment, as blanching can help maintain a vibrant color, especially when using a cabinet or solar dryer.

Methods for Drying Amaranth Leaves

1. Air Drying on Screens

This is a simple and low-cost method. Spread the clean, patted-dry leaves in a single layer on screens or a mesh rack. Place the screens in a warm, shady, and well-ventilated area, away from direct sunlight, which can cause color degradation.

Process: Wash leaves thoroughly and pat dry. Arrange them on screens with good air circulation from below. Turn the leaves occasionally for even drying. This method can take several days, depending on humidity.
Pros: Requires no special equipment. Preserves nutrients well if done correctly.
Cons: Slower process. Susceptible to dust and requires the right climate conditions to prevent mold.

2. Using a Food Dehydrator

For a faster, more controlled process, a food dehydrator is an excellent investment. This method eliminates the risk of mold and provides consistent results.

Process: Set the dehydrator to a low temperature, typically under 110°F (43°C). Arrange a single layer of leaves on the trays. The drying time is significantly reduced, often taking just a few hours.
Pros: Fast and efficient. Prevents nutrient loss. Controlled environment minimizes risk of spoilage.
Cons: Requires special equipment and electricity.

3. Oven Drying (Small Batches)

This method is suitable for smaller quantities but requires careful monitoring to prevent scorching.

Process: Place a single layer of leaves on a baking sheet lined with parchment paper. Use the oven's lowest possible temperature, keeping the door slightly ajar to allow moisture to escape. Leaves will dry quickly, so check frequently.
Pros: Utilizes existing kitchen equipment. Quick for small amounts.
Cons: Less precise temperature control. Higher risk of burning leaves if not monitored carefully.

Harvesting and Drying Amaranth Seeds

Harvesting and drying amaranth seeds requires timing and patience to get a clean, dry yield. Amaranth seeds ripen about three months after planting, when the flower heads begin to dry and seeds can be shaken loose.

Steps for Drying Amaranth Seeds

Harvest the Seed Heads: When the flower plumes are dry and brittle, cut the entire stalk. You can also monitor for when seeds begin to fall with a gentle shake.
Hang to Cure: Hang the stalks upside down over a tarp or in a paper bag in a cool, dry place for several weeks to let them fully cure. This ensures all seeds are mature and dry.
Threshing: Vigorously shake the bag or rub the seed heads between your hands over a tray to release the seeds and chaff.
Winnowing: Separate the seeds from the lighter chaff. This can be done by pouring the mixture from one container to another in a steady breeze, allowing the wind to carry the chaff away.
Final Drying and Storage: Spread the seeds in a thin layer on a tray for a few days to ensure they are completely dry before storing. Store in an airtight container in a cool, dark, and dry place for up to 6 months.

Drying Amaranth Flowers for Crafts

For those interested in decorative uses, amaranth flowers are also excellent for drying and retain their color well if kept out of direct sunlight.

Love-Lies-Bleeding (Trailing): Hang these varieties upside down in a warm, dry place. The ropes will dry in about two weeks and retain their cascading shape.
Spike Varieties: For an upright form, place the cut stems in a vase with a small amount of water. As the plant absorbs the water, it will begin to dry, keeping its shape and color.

Problems to Avoid When Drying Amaranth

Mold: The most common issue arises from incomplete drying. Ensure leaves and seeds are bone-dry before storing. In humid conditions, a dehydrator or oven is safer than air drying.
Loss of Color: Direct sunlight is the enemy of dried flowers and leaves. Dry all plant parts in a dark or shady area to preserve their color.
Incomplete Threshing: With seeds, rubbing too gently won't separate all the seeds from the chaff. Be sure to rub the flower heads vigorously to release all the grain.
Rancidity: Amaranth seeds have oils that can go rancid over time. Proper storage in an airtight container in a cool, dark place is essential for maximizing shelf life.

Conclusion

In short, amaranth does dry well, offering versatile options for preserving its leaves, seeds, and ornamental flowers. The best method depends on the plant part and your available resources. For leaves, a dehydrator provides the most reliable and efficient results for long-term storage, while air drying is a low-cost alternative for dry climates. Successfully drying amaranth seeds for consumption or sowing requires a multi-step process of curing, threshing, and winnowing to ensure maximum dryness and purity. Finally, the dramatic flowers of amaranth can be easily preserved for everlasting floral displays with a simple air-drying technique. Following the right method for each component guarantees you can enjoy this versatile plant long after the growing season has ended.
