Sweet Potatoes – Proper Fertilization
Q: I’m growing Beauregard sweet potatoes. One source says they are light feeders but another says they are heavy feeders. How should they be fertilized?
A: UGA gardening expert Bob Westerfield says he would class sweet potatoes in the medium feeder category. He fertilizes his at planting with 15-20 pounds of 10-10-10 fertilizer per 1000 square feet. Three weeks later he’s back with 15 pounds of 12-4-8 per 1000 square feet.
They then get one more feeding four weeks later with 12-4-8 again. Bob reports he gets a super yield each year if he can keep the deer and mice out of them!
