How can I harvest seeds from the Amaranth

Try tying a large paper bag over the flowerhead when it looks ready to change to seeds.

Just an idea for folks looking to get red garnet amaranth seeds... Mr Fothergills sells a pack of microgreens called Flavours Of West Europe, which includes a pack of red garnet amaranth, along with cress and morgan field peas. It was the only Amaranth variety that Bunnings seems to sell, but I also figured it would be worth growing cress and field peas as well to see how well they do in my current growing situation.

I've recently started growing amaranth in pots. They have done really well indoors but they are getting too large and I have started putting them on the patio. I live in a hot dry climate 9B is what I'm getting for Phoenix Arizona. So my concern is if it can survive Heat more than winter as Winters do not get very cold here can you give me any tips for keeping it healthy here and a hot/warm dry climate? Would they survive if planted in the ground better? The ground here can be very hard. Do you think it would be safer to keep them in pot so I can bring them indoors and move around if needed?

We're about 150 miles west of Phoenix and have been growing the same stand of Amaranth for 6 years. Yours will be just fine.

Is there a strain of Amaranth that will re-seed itself and survive in zone 6 or 5 ?

If you can grow Amaranth to full maturity on your property then it will produce viable seed, but being in a cold climate will be pretty lucky if it will germinate without you actually starting the seeds indoors early enough to make it possible to grow from seed to full maturity again. But you could grow it and save your mature seed and start them each year in pots. Hope this helps. Happy Gardening!

almost if not all amaranth such as palmer amaranth, prostrate pigweed, Powell amaranth and many more are all able to self seed and germinate, as such they are classified as weeds more than as a horticultural crop. The winter actually helps them with that, it puts them into a dormant stage which is required prior to them germinating the next year. of course if there is a quick warm time and then it gets cold again the seed could start germinating too early and ultimately die off prior to the right temperatures staying. But in most cases the first reason above is why they autoreplenish at a incredible rate.

I've already harvested n cut back the tops. I grew them in a grow bag, is it possible to overwinter them inside my house under lights? If I do will the survive and grow flowers again?
