at 6 foot unless you got a ladder. lol jk i have no clue.

Stop when you want to. The only real rule is to cover the tubers deeply enough so sunlight can't touch the tubers, and it sounds like you're well past that point.

This was my first year too so it's good to hear what to do. Won't be long and I will stop too. Vines are so healthy!

A ladder. LOL Reminds me of a question I had from some Californians who had moved here to Kansas. "Why so many two story houses," they asked. I explained that in the winter, when you're snowed in, you go upstairs and jump out a window.

I keep wondering how much hilling actually does any good. No matter how high you hill them, they end up with the same number of vines, the same length vines, and the same number of leaves. IMO, at some point, the potato-producing potential of the leaves is reached and any more hilling is a waste of time. I have no idea what that height would be.

tcstoehr, hilling isn't for the leaves or stems, it's for the roots. Potato platns will form new tubers along the stem where it has contact with the soil.

I have read that it is best to stop hilling once they are in bloom, and that is exactly what I plan to do this year. Incidentally, my potato plants are doing excellent and I have found that they require little to no attention. I dug a trench about 10 inches deep, fertilized, put down tubers and covered with pine needles. Haven't had to water since and am hilling with more pine needles.
