This tool is a resource provided by Johnny’s Selected Seeds, designed to assist gardeners and growers in planning the timing of their seed starting activities. It functions by calculating the optimal dates for sowing seeds indoors, taking into account factors such as the plant’s days to maturity and the average last frost date in a specific geographic location. As an example, a user might input the number of days a tomato variety requires to reach maturity and their local average last frost date to determine when to begin the seed starting process indoors.
The significance of such a resource lies in its ability to improve the efficiency and success rate of seed starting. By accurately calculating the ideal sowing time, it helps prevent issues such as plants becoming root-bound before transplanting outdoors or seedlings being started too late in the season, potentially shortening the harvest window. Historically, growers relied on experience and general guidelines for timing seed starts. This calculator provides a more precise, data-driven approach, reducing guesswork and contributing to better overall crop yields.
