We had 6-8 potato plants grow after planting. We built up the dirt with bricks around them, but now all but two have died once covered with more dirt. I was told you could harvest once they flowered and they have been in the ground for a good two to three months. However, when we dug them up there was only two pea sized potatoes on one of the vines, which was disappointing to say the least. Any ideas?

Wait for ur plants to die off completely and then harvest meanwhile put some compost or veg peels , grass cuttings on the soil.. And if yur plant has disease I may suggest plant afresh in a fresh spot with heaps of compost and loose soil and give ur plant a bit of room.. Use season once a week and u ll be amazed by the produce:)

I had the same problem but I was growing them in winter, which season were you growing in? Generally the longer you leave the potatoes the larger they get, it should be harvest time when the plant starts to die. Give them a bit more time. Did you add any nutrients to the soil? Other than that I can't think of where you may have gone wrong, maybe the potatoes were disease infested, did the dying plants appear to be suffering from disease?

I have grown potatoes several times but never had flowers. I harvest potatoes (when I get sick of waiting for the flowers) but can't understand why everyones says "wait till it flowers". Do all varieties flower??

No, not all potato varieties flower. If you have the patience, wait until the plant dies, then you can be sure you've waited long enough. If I'm after new potatoes I start bandicooting at around the 90 day mark, or when the plant starts to look a bit ratty.

The potato plants in our pre-school are starting to die down and ready for harvest in about two weeks. The children are eager to harvest them. Can the pre-school catering cook, clean and cook the potatoes immediately after harvesting them, or do they have to cure first for 10 days? thank you Grandmother to a pre-schooler Sylvana

Sylvana - Yes, you can use the potatoes straight away. They will be delicious 'new' potatoes which just need their skins rubbed off before cooking. The drying time is to ensure that potatoes will keep in storage. It hardens the skins.

Technically you don't HAVE TO HILL any variety of potatoes. Here's how it works: you plant the seed potato (which is an extra small potato saved/stored from last year's harvest -- or a piece of a larger potato that you stored/saved from last year) -- the DEPTH THAT you PLANT that SEED POTATO determines your LOWEST POINT -- GENERALLY, and I do mean GENERALLY (like 95% of the potatoes) the potato plant will not create tubers LOWER than the depth you planted the seed potato at (so your seed potato is the BOTTOM of the plants tubers/potatoes). Which is why some people think the very bottom potato always rots, when in reality it is the seed potato and is expected to grow and will appear rotten. Which means if you don't hill up as your potato plant grows and you planted the seed potato shallow, there is not that much ROOM for the potato plant to put it's tubers, and larger tubers will usually "pop" out of the soil and turn green due to sun exposure. If you don't want to hill up, plant your seed potato deeper than recommended -- yes it will be fine -- the reason you plant shallow and mound up is because the potato plant will be able to get leaves into the sun sooner if it's seed potato was planted shallow, which means it will grow quicker because it is collecting light sooner -- then you mound up to offset that you planted the seed potato shallow, but you always leave lots of leaves exposed to the sun so the plant can collect sun and grow. It's a lot of extra work work to mound up soil-- and maybe speeds up the process "brings in the harvest" by 10 days or so.... My experience is planting seed potatoes a foot deep ((30cm) is fine -- yes the plant takes a little longer for it's leaves to surface -- but it's fine and you should not experience any problems - provided the soil is nice and loose. (hopefully that makes senses). I think in the future I will plant two potatoes side by side -- one deep, one using the mound method and record the progress and final outcomes... I have never done a tandem planting -- BUT I HAVE had potatoes spring up from deep down Once as I dug out one of these "self planted potatoes" I realized it was down about 30" (70cm) -- it was in a potato planting tower (old full size garbage can full of 3" holes all over) which I dumped and collect the potatoes from the year before, then just put the soil back, week by week, as I composted kitchen scraps directly into the soil... so no surprise that a potato was so deep -- it grew -- it put out potatoes and it's crop was average good... it spent a lot of energy growing up -- and perhaps I harvested too early based on the other potatoes-- but it made it and did OK, good size potatoes, good quantity. I would not recommend placing your seed potatoes that deep, but a foot (30cm) should be fine.
