Amaranth Seeds,
Chinese Multicolor Spinach

The optimal time to plant Chinese Multicolor Spinach amaranth is in late spring to early summer, once the danger of frost has passed and the soil has warmed up. Ideal soil temperatures for germination range between 65 to 90°F. In regions with mild winters, amaranth can sometimes be planted as late as early fall. The plant grows vigorously during the warm months and can be harvested repeatedly throughout the growing season​.

Seeds should be surface sown and spaced approximately 6 inches apart to allow adequate room for growth. If using a container, select one that is at least 12 inches deep and wide, ensuring proper drainage. Covering the seeds with a fine layer of compost or soil helps retain moisture and supports germination.

Keep the soil consistently moist, as the plant does not tolerate drought well despite its heat tolerance. Applying mulch around the base of the plants can help conserve moisture, especially in hotter climates. When the plants reach 4 to 6 inches in height, pinching off the top rosettes of leaves can encourage bushier growth and more leaf production, which is beneficial for continuous harvest. Regular weeding is necessary to reduce competition for nutrients and water​.

• When plants have matured, cut down the entire flower stalk, place in a large bag and shake vigorously to remove seeds
• Alternatively, place a colander on top of a bowl and massage the flower heads until the seeds drop. Winnow by gently shaking the seeds and blowing lightly on them to remove the plant pieces from the seeds
• Amaranth is wind pollinated, so if you are saving seeds, different varieties should be planted 1,000 feet away from each other to prevent cross pollination. Also, keep away related plants such as celosia, cockscomb, lambsquarter and pigweed to avoid cross pollination

Note: Amaranth seeds remain viable 5 to 7 years after harvest
