How to Plant Potatoes in a Cold Environment

Temperatures are supposed to go up to 80 this weekend, I think again. We don't plant potatoes here till the end of the month and that's like early. The only issue is if it gets too hot, too fast, the potato vines go. Tactical has asked me no fewer than four times in the last two days to come to this one part of my yard where my dog is buried. It's very obvious where her grave is because it's all about flower bulbs on it like in the grave. Show me what I can't weed whack over here.
