Planting date is more important for cold weather crops than soil temperature because these crops must get ahead of weeds and diseases that come with warm weather. For cold weather crops, once you reach the planting date and soil temperature minimum, it is time to plant; unless an unusually hard freeze is predicted.

Organic, regenerative, and sustainable certifications are useful to indicate to consumers that agricultural practices are being used which are focused on the long term future of the land. But, these standards still need to continue to evolve. Many of them are still written to protect against the kinds of diseases that come with industrial agriculture. They are not written to encourage the natural disease suppression that comes with a diversified organic farm.
