Factors Influencing Planting Times
Understanding various factors influencing planting times helps you better plan your Oklahoma garden. Two critical elements are frost dates and soil temperature.
Frost Dates
Frost dates dictate when you can safely plant. In Oklahoma, average frost dates vary by region. For instance, the last frost typically occurs between mid-April and late April, while the first frost arrives in late October to early November.
