About Green Tails, Amaranth Seed, Amaranth Seed

Trailing amaranth features vivid, cascading tassels in a striking lime green, bringing bold texture and movement to any arrangement. Its long, flowing flower tails drape elegantly from tall plants reaching 4–5 feet, creating a dramatic visual effect both in the garden and in the vase. Ideal for fresh or dried use, this ornamental variety shines in bouquets and pairs beautifully with other amaranths. Planted in rows, it also forms a lush, eye-catching backdrop for smaller blooms, adding depth and dimension to your garden design.

Before Planting

Reserve a warm, sunny bed with loose soil and space for the selected amaranth’s mature height. Remove weeds before sowing because the tiny seedlings are difficult to cultivate, and avoid excess nitrogen where lodging is likely.

Planting

Direct sow amaranth after frost when soil is at least 65°F, or start indoors only 3–4 weeks earlier to avoid rootbound seedlings. Cover seed about 1/4 inch and maintain 70–75°F until emergence. Harden carefully, transplant into warm soil, and thin grain types to 10–18 inches or greens more closely.

Watering

Keep the seed zone damp through emergence, then shift to deeper irrigation as roots expand. Established plants handle short droughts, but grain and leaf production fall if they remain dry during flowering or rapid vegetative growth.

Fertilizer

A modest compost application is usually adequate. Side-dress leafy amaranth after repeated cutting only if color fades; grain and ornamental types need little nitrogen because lush, top-heavy stems lodge readily.

Harvesting

Harvest amaranth leaves while young and tender, taking outer leaves or cutting shoots above a node for regrowth. For grain, wait until flower heads dry and seeds release when rubbed; cut heads into bags, finish drying under cover, then thresh and winnow.

Tips

Stake tall ornamental forms before seed heads become heavy. For edible leaves, cut young tips repeatedly; for grain, isolate varieties if seed purity matters and remove volunteer plants before they become weedy.

Pests & Diseases

Damping-off, root rots, leaf spots, and white rust may affect amaranth. Watch for seedling collapse, dark roots, expanding leaf lesions, or pale raised pustules beneath leaves. Sow into warm, well-drained soil, rotate crops, avoid overhead irrigation, remove infected residue, and provide spacing that lets foliage dry quickly.

Flea beetles and caterpillars damage young leaves; tarnished plant bugs and aphids feed on shoots and seed heads. Inspect seedlings frequently, remove caterpillars, and control nearby pigweed relatives that harbor pests. Protect ripening grain with netting if finches or other birds become destructive.
