A drop in temperature overnight aids germination. seeds can be started indoors for transplanting. Transplants can be started approximately 6 to 8 weeks before the spring arrives, but seeds should not be sown outdoors until all danger of frost has passed. Seeds should be sown to a depth of 1–2 cm in rows spaced 10 to 12 inches apart.
To harvest Red spinach just pick the individual leaves as needed for greens. Younger greens are great for salad, older greens are better cooked as a substitute for spinach. The time from planting to harvest is 20 to 30 days from seed. You can also cut your amaranthus dubius when it is between one and two feet tall. You must cut the whole stem, maybe six to ten inches above the ground. The stem will re-shoot and can be harvested again.
Seeds ripen about three months after planting, usually in the mid-to-late summer, depending on your climate and when you planted. They are ready to harvest when they begin to fall from the flower head. Give the tassel a gentle shake. If you see seeds falling from the tassel, it’s amaranth harvest time.
