Look up your climate zone. Then select your crop to plant, then check the calendar when you can plant. Read the notes about growing it.

Hi, I am interested in growing sunflowers in large quantities. I do own large open fields with the advantage of long hours of daily sunlight. I live in Lesotho, just outside of the capital town Maseru, completely surrounded by South Africa. It is currently winter but warming up very quickly with Spring coming in September, When is the best time to plant seeds?
