As they grow, there will be a green plant that lets you know where the main steam is. After a while you may start to see potatoes coming to the surface. Cover these with more soil or straw. Keep covering any potatoes you see with more soil. Do not pick or eat green potatoes.
After a month, loosely turn soil of the largest green stalk and see how your potatoes are doing. You can harvest them at any size as long as they are not green. If they aren't big enough, push them back in the ground and cover.
I have had the best results with red and yukon gold but russets have done OK. I've gotten a few pounds of potatoes with almost no work and its great fun to grow something from what others would consider garbage.
While you're at it, throw any rotten tomatoes in the ground. The grape and cherry always grow in my garden.

My neighbor planted some Red Russets late February. That's the appropriate time for planting potatoes in our region. None have broken through the ground yet. That's a good thing because our official last frost date is April 15. We probably wont have any more frost this season, but Mother Nature knows best and she will decide when the potatoes should poke their foliage through the soil.
I, on the other hand, like to experiment. I bought two 5 lb bags of White Russets. They started to sprout before I could cook them all. I said 'What the heck, I'll cut off some sprouts and plant them indoors, just to see what happens'.
Well, my neighbor's spuds aren't up yet, but mine are. About a foot, actually. I think we've seen our last frost, but I believe it's still cold enough to hurt the foliage, if I were to I put them out now.
I'm going to send the local Ag Agent a picture of my potatoes and ask him how they should be treated at this time; wait a while, plant now, plant now with protection against cold? etc.
Everyone should know their local Ag Agent. Your taxes pays their salary. They are there to help you with gardening questions and there's no charge for their services. I haven't met one yet who wasn't very nice and very anxious to answer my questions.
PS: I planted several containers of Yukon Gold as well, and under the same conditions. None have sprouted. I assume they had been treated to prevent sprouting. Oh, well, guess I'll have to buy a bag of Yukon Gold seed potatoes. It'll be worth it. They arethe best potato I've ever tasted.

Fill the boxes with dirt and plant your potatoes, remember to water and weed. When it comes time, either break, tear, or dump the dirt from the boxes and pick up the 'taters!
The potatoes are easy to find, and are huge. This is the only way I can grow potatoes, that my husband likes to dig them. The straw doesn't blow away and we live in KS where there is wind from 0-50 mph all in one day some days.
Another easy method is to mulch up leaves in the fall and place potatoes on the partially decomposed leaves in the spring. Cover the pile with 1 to 1 1/2 feet of straw, mulching as needed to keep tubers covered.

I just found a bag of potatoes with sprouts as long as 10 inches; there is no smell to the bag. Can I plant them? And do I cut the potatoes in half with sprout attached or put the whole potato with sprouts in ground? I've never planted potatoes. Thanks for your help.

You just came upon what I did. In my case, a small bag of purple potatoes that are shriveled and have some very strong sprouts that made their way through the plastic bag!! Well, I did some searching this morning and I found a great guy who has a site called "Balcony Jungle." He shows a picture of how my potatoes look and then explains a very concise method of getting them planted. Here is the link for the page I found. Hope this will help you out like it did me!!
Good Luck! Mine are planted in a make-shift "self-watering" container as I write this!
Can I grow a plant from a potato eye?

You need a piece of potato with that least 2 eyes, after cutting the potato in sections it really should set out and dry a bit or dust it with sulfur, you cannot grow potato plants from just a sprout you really need a piece of potato attached. After planting your potato, once it's about 3 to 4 in. tall start piling dirt up around the stem (I usually dig the hole and slowly fill in as the potato grows.)
Now the sweet potato is a totally different thing you have to wait for them to sprout, once the sprouts are at least 3 in. long carefully snap off put it in small glass with a little bit of water once roots form that's when you plant them.
What is the best N.P.P. ratio for a good crop of spuds?
I have little space and want to plant potatoes. I have heard they do not go good near other vegetable plants. Which plants are good to plant next to potatoes?

Potatoes shouldn't be grown near tomatoes, I think because of risk of blight. They're supposed to do well near beans and corn though. Potatoes do well in tubs (especially early varieties) so you might consider growing them in containers where you could keep them away from other vegetables in the patch if need be.
Our potatoes are growing very long spindly tops and there are very few. There are only a few very small spuds per hill. Would it help to mow the tops off at some point to get more and bigger spuds? Any other suggestions would be helpful.
