How to Plant an Annuals Garden

Maintaining Annuals Month by Month
The following chart lists the various gardening tasks to be done each year.

When they should be done depends on the climate in your area. This month-by-month chart indicates when each task should be performed based on the different average annual minimum temperatures in North America. Because conditions can differ, and dates of first and last freezes of the season vary each year, these are only approximate guides, but they will provide you with a general outline for your garden year.
