I VE NEVER GROWN DUTCH CREAMS HOW DO YOU THINK THEY WOULD GROW IN CONTAINERS AS I AM CONDUCTING DIFFERENT METHODS WITH DIFFERENT TYPES OF SPUDS IN CONTAINERS BAGS DRUMS ETC

I have several boxes of small potatoes left over from a crop I grew from certified seed potatoes last summer. I would like to plant them this coming spring, (August onward) but they are already statrting to sprout. If I siply remove the sprouts now and keep them dry and in the dark, will they be suitable for planting in 12-16 weeks time? Thanks for anyones interest, Regards, Clive.

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.

I heard that the potato will stop sending nutrients to the tubers if the stalks are bent. One of the most successful potato harvests I have ever seen was a large container grown project where he used several layers (think of a layer cake) of horizontal plastic fencing and t-posts at each corner to hold the horizontal fencing to keep the stalks from bending at all and support them as they grew. They were able to get an absolutely massive yield with that method although he was sick all summer and didn't care for them or water them at all. I am not sure that the container growing was as pivotal in the results as just keeping the stalks from bending over. I have container grown before and will try it again this spring as well as ground growing using his methods to keep the stalks upright. I think another often overlooked issue is either too much or too little phosphorus and potash in 10-10-10 fertilizer. I think 'balanced' fertilizers can present real problems for root crops since they don't need or want balanced inputs. You will always have too much of something and too little of the other. Also there is a time delay on phosphorus while it stays in the upper part of the soil, so you can apply phosphorus to increase tuber formation, but it takes 3 months to disperse into the soil, while nitrogen sinks like a stone through soil an becomes almost immediately bio-unavailable (or runs off into the environment via water). So if you are using 10-10-10 you are going to end up poisoning your plants in order to get one or another nutrients available in the correct quantity. Plus factor in the time delay to bioavailability. I think it is better to thoroughly prepare soil before you put your garden to bed in the winter than prepare it in the spring (actually I have revived some fruit trees that were very old and no longer producing by fall fertilizing; I got almost $700 worth of organic pears and even more than this in apples last year through fall fertilizing). I also heard (and studied it last year in my own garden) that potatoes grow between the seed potato and the surface. If you bury them deep you will increase yields as there is more space for them to grow above the seed potato. But if you plant them shallow, they have a very narrow area to make potatoes in, significantly reducing production. This means in container gardening you need to put them at the very bottom of a 1'-6" (0.45 meters) tall container to get a full yield. I tried this method last year and doubled my production. I was putting them very close to the surface before last year. Also, potatoes need cool roots and won't produce anything at all if their roots are too hot in the container during the summer. Afternoon/evening shade is a must in Southern US zones or other hot environments. Or you could insulate or shade the container.
