Growth habit
I like warm and humid climate. Not afraid of drought, it is suitable for planting on wet land with abundant sunshine and fertile soil. Amaranth can be cultivated from spring to autumn, with suitable cultivation temperature in spring, long sunshine time, late bolting, tender quality and high yield. According to the market demand, it can also be cultivated in protected areas to achieve annual production.
Amaranth does not require much soil, but it grows well in alkaline soil. It has certain drought resistance and does not grow well in poorly drained fields.
The plot with flat terrain, convenient irrigation and drainage and few weeds should be chosen as the flat bed. Amaranth seeds are small, so the soil preparation must be fine, so that the ground is flat and the soil is fine, which is conducive to seedling emergence.
