Best fertilizer for sweet potatoes

Jesse103 · May 10, 2021

I am planning on growing some sweet potatoes this year in grow bags. I have used grow bags for tomatoes for a few years now. This is my first try at growing sweet potatoes. I will be using Miracle Grow Potting Mix in the bags. Can anyone share with me the kind of fertilizer they use when growing sweet potatoes in bags? I would appreciate any information.

I've never done sweets in a bag but I'd go with something lower in nitrogen and higher on the phos and potassium. You don't want to really push the vines with nitrogen at the expense of the potatoes sizing up. Just a thought. I use 5-10-15 granular in my row of sweets

Thanks GoDawgs. I'm in Greenwood about 50 miles from Augusta.

Last year was my first time growing sweet potatoes.
I planted some in grow bags, some in containers both 15 gallon. Don't put more than 1 slip in each container they need room to grow. The grow bags were harder to get the potatoes out of, the plastic containers you just dump the whole thing out on a trap. I didn't use any kind of fertilizer, just half potting soil and compost.
