    The planting dates are generally based, and approximate on the warming and temperature of the soil.

    For the Louisville, Kentucky area home gardener – between the 3rd Week of April and Derby Day are good times to plant most anything and everything for a home garden.  Some gardeners have planted as early as March, and as late as the running of the Belmont.
    Because there are ‘new and improved’ hybrids of many of plants developed each year, more detailed information should be taken from the seed packets as to actual timing and planting specifications in your area.

    As you plan which foods that you’d like to grow in your garden, remember that among other things, you must also take the following into account:
