Prolonging the tomato harvest
With the average date of the first killing frost approaching, many home vegetable growers are anxiously keeping an eye on their fall crop of tomatoes. Waiting for green tomatoes to ripen can be nerve racking, especially this time of the year. The final ripening process depends upon temperature, humidity, light levels and other environmental factors. The optimum temperature range for ripening is between 68 and 77 degrees. Outdoor temperatures below or above the optimum range will slow down the ripening process.
