Sweet Potato Project 2015

Are you ready to grow sweet potatoes for Madison Food Pantries?

Without funding, we have been working hard to make this project happen and are happy to announce that we will again be providing slips to local growers. However, things are a bit different this year.

If you’d like to participate, it’s a two step process:

1.      Provide a donation of at least $10 to the project via Slow Food Madison. You may take up to 20 slips to plant. Please note how many slips you would like in the “dedicate this donation” box.

2.      Pick up your slips at the Dane County UW-Extension office (directions here). Slips will arrive the week of June 8th.

Your donation to the project will cover the cost of your slips and the remaining will be grown by non-profit partner gardens to support food pantries.  If you choose to donate some of your harvest to a local pantry, you can find one here.

Curing and Donating Your Sweet Potatoes


The sweet potatoes will grow right up until the first frost.  At that point, you’ll need to dig them up. The latest 10 day forecast can help you keep track.


If you won’t be curing your sweet potatoes (read below), the best place to bring your donation is the Community Action Coalition, 1717 N Stoughton Rd, Madison. (map)

If you choose to drop them off at any other food pantries (map here) , please cure them first.

Also, once you donate, make sure to update us on how many pounds you donated.


The curing process heals any small wounds and enhances sweetness by converting the root’s starches to sugars. Ideally, the sweet potatoes should be kept in a space (greenhouse or 4-season porch) for about 10 days at 80-85°F at high humidity (85-90%). If that is not available, they can be cured next to a furnace for 2-3 weeks at 65-75°F. An option to achieve the required high humidity (85-90%) is to stack storage crates or boxes and cover them with paper or heavy cloth. Also, packing in perforated plastic bags will allow excess moisture to escape.


Once the sweet potatoes are cured, move them to a dark location where a temperature of about 55-60°F can be maintained during storage. Keep the sweet potatoes out of the refrigerator as they can be damaged by cold. Wrapping cured sweet potatoes in newspaper and storing them in a cool closet or basement is a great option. Stored properly in ideal conditions, sweet potatoes will last between 6-10 months!

Thank you and good luck!

1000 Pounds – Goodman Youth Grow Local Farm

Almost 1000 pounds! That’s how much sweet potatoes were harvested on Oct. 3rd at the Goodman Youth Grow Local Farm in Madison. Master Gardener Volunteers and youth farm interns worked with 100 elementary students from Kennedy & Van Hise Elementary Schools to harvest the sweet potatoes that were delivered to local food pantries.

Harvesting Soon

Most of our Beauregard sweet potato plants have reached the 100-day mark in their growing season so it’s time to consider harvesting procedures:

  • Due to the shorter growing season in our region, allow the plants to mature as long as possible before harvest.
  • Harvest should occur shortly before or directly after the first frost kills the vines. Roots continue to grow until vine die-off and are only susceptible when soil temperatures drop below 50 degrees; use a soil or meat thermometer to check.
  • After vine die-off, immediately remove the top growth to prevent decay from spreading the roots.
  • Dig about 1-2 feet from the base of the plant with a spade/pitch fork or shovel to uncover the your delicious, nutritious treasure.
  • Take care not to damage the roots as sweet potatoes lack the thick, protective layer like standard potato tubers. Sweet potatoes need to undergo the curing process to develop a thicker skin.
  • Resist temptation to clean the sweet potatoes before drying & curing as they may be damaged and become infected.

Watch for an updates soon about curing and donating ½ of your harvest!
