  • If Sweet Potatoes are in pots, bring them inside
  • If Sweet Potatoes are in the ground, cover them in burlap and hope they survive

Also, make sure not to plant your Sweet Potatoes in your garden too late.

  • Planting Sweet Potatoes too late will cause small Sweet Potatoes or even worse, no Sweet Potatoes.

  • Find the last average frost date HERE
  • And then subtract 42 days from it

Not only this, but I recommend again paying close attention to your local weather report.

It should also be noted that the best technique for bringing your Sweet Potato plants outside is to introduce them (in their pots) outside for an hour. And then increase the amount of time they spend outside each day by an hour until they have been outside for 8 hours.

This will “hardened” your Sweet Potato plant, increasing its chances of fighting off diseases, insects, droughts, and wet conditions.
