Growing Sweet Potatoes Indoors

The pantry is full of fall favorites like squash, pumpkins and sweet potatoes. But busy schedules may find a few things growing in the back of the cupboard. Don’t discard those sweet potatoes that sprout in storage. Make it a fun gardening activity for the family.

Plant the sprouting sweet potato in a container of well-drained potting mix. Plant it with the growing point just below the soil surface or lay it on its side and cover with potting mix. Grow your new plant in a sunny window and water as needed. Sweet potatoes make a great indoor plant.

To see what goes on below ground, try growing your sweet potato in water.  Stick 3 or 4 toothpicks around the middle of the sweet potato.  Set the toothpicks on the lip of a water-filled glass.  Keep the water covering the bottom half of the sweet potato. Place it in a bright location out of direct sun for rooting.

A bit more information: Take a look at other kitchen scraps you can grow into houseplants. Plant the base of the celery used in your dressing or the top of your pineapple. It’s a great way to move the garden indoors and keep little hands busy during the holidays.
