The most significant factor in deciding when to plant a crop is usually soil moisture. Adequate soil moisture is essential for seed germination and early plant establishment. If the soil is too dry at planting time, seeds may not germinate properly, leading to poor emergence and reduced yields. Conversely, overly wet soil can lead to issues such as seed rot or disease, which can also negatively impact crop establishment.

While seed cost, market prices, and frost dates can influence planting decisions, they do not have the same immediate and direct impact on the success of crop establishment as soil moisture does. Seed cost is a concern for overall production economics, market prices relate to the potential profitability of the crop later in the season, and frost dates help in determining the end of the growing season, but the health of the crop at planting time heavily relies on the available moisture in the soil. Thus, ensuring the right moisture level is paramount for optimal plant growth right from the start.
