Hi Diane, the small green berrys are actually seed pods, if you get these on your plants it means the potatoes are very happy where you've grown them and are in ideal conditions. If you use these seeds you can get a really good crop of genetically diverse potatoes unlike those grown from seed potatoes which will only produce clones. Cheers Tracey

Diane, Generally when plant leaves turn yellow it can be a sign of nitrogen deficiency. Perhaps you need to feed the spuds with some quick release fertiliser. It may also be that the plants are nearing maturity and dying back.... time to harvest? The green berries are perfectly normal and are the potato seeds. Kind of like a tiny tomato. If you were to plant these you would produce a new, unique variety of potato.

Is it too early in the year to plant now?
30 Jan 15, David (Australia - temperate climate)
Yes, too early, wait to August...August to Nov/Dec should be fine.

I am staying in NORTH WEST in MAHIKENG area and need to know best months to plant potatoes aswell a s the best seed suitable for our area...My other place consists of LOAM SOIL and the other is CLAY SOIL,,,I need to know which is best suited ?...Thanking you in advance...

Potatoes like loam sandy soil not clay in mpumulanga in a small town for many years there where a potato festival and the soil there is loam. By my also in mpumulanga we have turf soil similar to clay yet soil is very stiff hard like stone when it hasnt come in contact with rain and cracks up very deep below

Do potatoes mind clay soil. I heard they grow anyway and will help to break up the soil

The handbook-which I provided the location to in my prior reply is not very beginner'ish but it is comprehensive covering issues you may never encounter- but you do need the reference material. I have a few thoughts to add. 1. Hilling up while the plant is growing-if you are covering leaves I find this fundamentally wrong. Leaves are specialized and designed to collect light, they are not roots. So I opt to plant my seed potatoes deep enough on day one- however I tend to have the luxury of very well airated, light soil. This means the seed potato has a steady air supply and can sense the heat from the sun even at deeper depths 2. Your seedpotatoes need all their potassium Immediately. Potatoes strangely take up all their potassium that they need really early. -and don't uptake more. If there is not enough potassium in the very early stages your potatoes might have hollow heart (looks like hollow rotting middles). Late application of potassium tends to be useless 3. Potatoes seem to respond really well to the addition of microryzal fungi - in my area we source that under pine trees in a forest- we just take some forest floor duff with a dust pan and add to the potatoe planting soil. To sum up - your seed Potatoes should be about the size of chicken eggs (if larger cut up ensuring an eye on each piece and allow a few days to heal/scab up before planting). You need to chit them(make them sprout-place in dark so they sprout). Plant in soil with Compost, a sorce of potassium and microryzal fungi. If for some reason you cannot source any compost/pottasium/microryzal fungi -plant anyhow potatoes are tough -there is still a good chance they will be Okay -depends on the condition of you soil. In my area I can water deeply once per week. Harvest when about half the leaves have fallen over as if to die. If you harvest sooner you may be compromising on size-because as long as those leaves can collect light they can store the energy in the tubers. Good luck - it is so much easier than it sounds- and all those diseases in the handbook are rare and if the plants are strong (well fed) they can manage just fine, potaoes are pretty tough root crop. In other words- you can grow potatoe.
