3-Pack of Clyde's very handy Vegetable Planting Slide Chart. One chart to put with tools and seeds. One chart to keep on hand as a quick reference when making garden plans. And .. One chart to share with a vegetable gardening friend. Chart presents gardening events in a time-phased format, using a horizontal calendar so that it is possible to see the entire Planting, Growing, and Harvesting period at a glance. Chart shows proper Indoor and Outdoor planting times relative to local spring and fall frost dates for 22 commonly grown garden vegetables. Since frost dates vary, the RED frost line slides, making Clyde's chart useful in most parts of the Northern Hemisphere, where frost is a critical gardening factor. A Listing of Local Spring and Fall frost dates is included in the directions, (US and Canada). The front of the chart presents the Spring Season, and the flip side acts as a guide for Fall gardeners.
