The calendar is the first filter

Plant only when the crop is ready

A range can be correct for the region and still be unsuitable for today. Check the crop and the garden before committing seed or plants.

  • The soil is warm and drains well.
  • The site has full sun and enough growing season remaining.
  • The slips are healthy and can be watered in promptly.

How to start sweet potatoes

Use slips rather than botanical seed. Plant only when the garden has enough heat for a long warm-season crop.

Match the sweet potatoes method

Use slips rather than botanical seed. Plant only when the garden has enough heat for a long warm-season crop.

Make the weather decision

A published window is a planning range. Wait when soil condition, moisture, heat or cold makes establishment unsafe.

When the simple answer breaks

Early and late decisions

The useful answer is an action when weather or the remaining season no longer fits the headline range.

The season is early

Use the protective edge of the range

Planting at the first possible date is reasonable only when the crop and forecast support it; a calendar is not a command.

The season is late

Count maturity before committing

Check the variety’s days to harvest and leave a margin for establishment. A late start can look healthy but still fail to produce usable roots before the season closes.
