We used to plow the dirt up onto the sides of the plants, but I've just let them grow the way they are and they still produce. The biggest thing about potatoes is to have enough loose dirt below the seed potato. I planted some in a hole and filled it with hay. They went crazy and had a lot of produce.
FWIW, we are expected to hit 92 tomorrow and 97 on Thursday. The tomato plants are loaded. My garden is kind of wet with the 1.2" rain we had the other night. I noticed some tomato and pepper plants already have yellowing leaves from too much water.
Thanks. The plants are almost two feet tall and flowering. I dug around and not one sign of a spud.
I guess I’ll just wait and see.
