For best results, especially if you want to stagger plantings, start amaranth indoors first. If you sow seeds directly outdoors, wait until a week or two after the last frost to allow the soil to warm up. Same with transplanting—these are warm-weather plants and frost won’t do you any favors.
When should I plant amaranth seeds?
Amaranth prefers warm weather. If planting outdoors, sow Amaranth seeds after the soil has begun to warm in the spring. We recommend an indoor start, six to eight weeks before the last frost in your area.
When to Plant Amaranth in Florida As you may have already guessed, you need to pay very close attention to your local weather in the spring. Specifically, you are going to need to watch when the last frost occurs. In general, when there hasn’t been a frost for two weeks, you are SAFE to plant your amaranth outside in Florida!
How deep do you plant amaranth seeds?
Amaranth grows well in a variety of soil types. Generally speaking, those soils suitable for growing lettuce would make a nice place for growing amaranth. Your soil should be finely prepared to achieve the proper seed planting depth. Seeds should be planted no more than 1/4 inch deep.
Thanks to their plentiful seeds, amaranth plants will readily self-seed in the garden. As they sprout in spring, the volunteers can be thinned out to about 10 to 18 inches apart, or carefully dug up and transplanted elsewhere.
How to take care of amaranth?
Amaranth does best in full sun in the northern part of its range, but in warm southern climates, it can benefit from some shade in the afternoon. Amaranth grows well in average soils and will even grow adequately in poor soils. 4 temperature and humidity, 3 water, or 5 fertilizer too are a couple more ideas to investigate.
Ideally, amaranth needs a few inches of water once or twice a week. Rotate plants from year to year to avoid diseases. Don’t plant where you’ve had brassicas the previous year. If you want to make sure you have a continuous supply of leaves and flowers, you can plant amaranth 2 weeks apart.
Is amaranth fun to grow?
We all have plants we like to grow for “fun.” Amaranth is one of those fun plants for me. The leaves and seeds are an excellent source of nutrition, but I love just to watch the plants grow.
