Sweet Potatoes

We are attempting to grow sweet potatoes in our garden for the first time this summer!  Unlike regular potatoes, sweet potatoes like it hot!  They are native to Central and South America. Their vines need room to grow so after our tomatoes, okra and other veggies cleared out of the garden, we planted two sweet potatoes that had gotten old in our pantry.  We first started them in a glass full of water on the kitchen counter.  Much like an avocado, they simply sprouted leaves and roots.

I realized that I started them a bit late. It is recommended they are started in April and May in Florida because they have a 95-120 day harvest.  We started ours in June.  However, they are doing well in the garden and myself and the little gardeners are looking forward to this experience.  

The next step is mulching.  They love mulch to help promote new vines & growth. Here are some other tips I found for planting, growing & harvesting sweet potatoes:

  • Plant sweet potatoes about 12 inches apart, and allow 3 feet between rows so the vines will have plenty of room to run.
  • Good root development depends on aerated soil (that’s why they like mulch). They are the ideal crop for areas with sandy soil.
  • About 2 weeks after planting, feed plants with a balanced organic fertilizer that contains potassium (the third number on the fertilizer label).
  • Sweet potatoes are not very sweet when first dug, but they are fine for sweetened pies or casseroles. They need a period to sit and “cure” to bring out their sweetness. Don’t wash before curing.
  • In late summer, sweet potatoes often produce flowers that resemble those of morning glory, a close botanical cousin.  
  • Taken from various online sources, including: http://www.bonnieplants.com/LearnGrowLibrary/HowtoGrowBonnieVarieties/tabid/128/ID/220/How-to-Grow-Sweet-Potatoes.aspx

We are looking forward to vines, flowers & curing potatoes later this summer! Fingers crossed!

Happy Gardening!
