What is the minimum soil temperature for planting cotton?

The minimum soil temperature for planting cotton is critical for ensuring optimal seed germination and seedling establishment. Cotton seeds require a soil temperature of at least 60 degrees Fahrenheit for effective germination to occur. However, planting at temperatures around this threshold can lead to slower germination and increased vulnerability to diseases and pests.

When considering the optimal temperature range, while 60 degrees is somewhat acceptable, many experts advise that a soil temperature closer to 65 degrees Fahrenheit is ideal. At this temperature, seeds will germinate uniformly and more quickly, leading to healthier seedlings that can better withstand environmental stresses. Thus, 65 degrees Fahrenheit is not only a safe minimum that promotes robust growth but also minimizes risks associated with lower temperatures, such as delayed emergence and poor stand establishment.

So, while 60 degrees is the bare minimum, 65 degrees is favored to ensure that cotton plants develop optimally right from the start.
