Note for Hot Climate Gardeners

Frost dates are the most common indicator for figuring out when to start seeds. However, if you live in a hot, dry climate, or at a high elevation, frost dates might not always be your best guide.

Check with your local extension office to get ideal planting dates relative to your unique conditions.

Get your seed starting dates automatically calculated for you!

Staying on course and starting seeds at the right time requires just a bit of planning and organization. Imagine a tool in which you type in your frost date, and it automatically calculates the following FOR 70 CROPS:

  • indoor seed starting dates
  • transplanting dates
  • direct sowing outside dates
    • succession planting (how many days between sowing for a continuous harvest)
  • spacing in the garden
  • days to harvest
  • companion planting suggestions
  • special soil amendments
  • PLUS, fall planting dates for each crop for a continuous, year-round harvest.

Sound amazing?

The good news: This tool exists, and it is just one of six tools you receive with my Complete Garden Planning System, which includes practical tools for planning your season from seed to harvest.
