Growing Sweet Potatoes (Northern)

Question

I planted sweet potatoes in hilled, fertilized soil. I put black plastic over the hills for 2 weeks before planting the sweet potatoes. The average temp. here is between 57 at night and usually in the mid 60’s to 70’s during the day. Do I need to do more? Can I expect at least some potatoes? Do I need to put row covers over them? We have frosts in mid Sept.
