How to use the Seed sowing and succession planting spreadsheet

There are two pages on the spreadsheet, and the areas you can influence the calculations are highlighted in yellow.

Insert your frost dates into the appropriate boxes highlighted in yellow at the top of the first page.

The given planting dates should work for most temperate climates. If you are approaching the antarctic/arctic or tropical zones will need to use techniques to either extend your season or shield cold loving crops from the heat.

Dates for succession and Autumn/Fall planting columns are triggered by you putting an X in the Autumn/Fall and Succession planting columns.

They are calculated by the first frost date, days of harvest, and recommend succession planting dates (which you can change on the second page).

If you want longer times between successions you can change the time in the second ‘Plant info’ sheet.

You might want only one or two plantings of a variety, or you might want as many as you can – so you can change this to suit.

Once you’ve got your first planting dates, you can establish the dates for starting seedlings indoors for those vegetables that you intend to transplant. 

For those vegetables that only produce for a limited time, remember that you can often use succession planting to extend the harvest. 

Do the above for each vegetable you’re growing and you’ve got a handy schedule for planting your garden, and if you keep notes and tweak it each year, it will only get better.

Be sure to write in your notebook what varieties you have grown and how they have done. This will help you decide which varieties to grow again next year.
