if you filled them half to 2/3's with mix, then planted your seed potatoes. As the potatoes grow you continue to add more mix until the container is full. (Beach_bum) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ I agree with Beach_bum. Potato needs HILLing. So in the pot you keep adding soil as it grows. This will provide room for the tubers. ALSO, the plant draws the nutrients from the lower part of the soil. What you fill/hill with, does need to be fertile. A mixture of peat and pine fine will do(like 5-1-1). So here is what I would do: --- Fill about 10"(rich soil): REMEMBER that the roots will grow ONLY in this soil, not above it. --- Place the seed(s) on it. --- Cover with about 4" of soil Do hilling/filling as the plant grows.

I have never done this, but I have read about it may times. If you take a large trash can (with drainage holes drilled in) and fill it with 10-12 inches of soil. Then you plant your seed potatoes eye up (I think it was eye up....) I cant remember how many you can plant, but I seam to remember that they can be pretty close together. Then as the plant grows a bit you fill up the trash can up to the first set of leaves (the more roots they have the more potatoes they produce). You continue to do this until the dirt is above the trash can line in a mound. Make sure that the mound is lower around the edge of the trash can so that you can water. Then when ever you want to harvest the potatoes just dig down a bit and you have potatoes. Or you can dump everything out onto a tarp and get them all at once. There is another way to do it with wire caging and straw, but it seams much more complicated than filling up a trash can. Onions can be easily be grown in containers, it can be a small operation with one onion per small plastic pot or much larger. My grandfather grows all sorts of stuff in plastic feed troughs with holes drilled in, meant for horses and cattle purchased at the local hardware store. I would imagine that one or two feed troughs for give you plenty of onions. As an added bonus they are raised almost to waist height so you donÂt have to bend down hardly at all. I use old black heavy duty nursery pots for my plants. They arenÂt pretty but they were free and work great. I wouldnÂt personally grow potatoes in a bag, because you would have no way to Âmound up the soil, therefore increasing your yield . I have herd of people doing this with tomatoes pretty successfully so I guess you could use it for onions, but I think it would be easer and more successfully donÂt in containers. Either way good luck and congratulations on the new house.

Likewise I have never planted sweet potatoes in a container or bags. But have seen pictures of those who have and they just let the vines spread out over them and down to the ground. And from the reports I've read they produce well. Production is very hard to predict. Weather conditions can cause production to change a lot. The same varieties I dug up to nine pounds in 010 from didn't produce a pound after the hail and the hot, droughty summer last year. And the one I planted in mid July produced several tubers but none as large as the one they were produced from. I would say the most I dug last season was around 5 pounds. The same variety that produced nine pounds the year before. So very hard to predict. And then again growing in a bag, container may affect production also. Jay

Potatoes in bags? Question has already been answered. Rodney
