Growing Potato

05 Jan 20 Sarah-Jane Wicks (Australia - temperate climate): We used seed potatoes to grow Kilgore in our school garden. As the tops have now died off we harvested them today, only to yield Ferny tiny potatoes. Less than 300g from a whole 3.6m x 1.2m garden bed. The potatoes were watered a minimum of 4-5days per week, were regularly fertilised and grown beside sweetcorn. How did this go so wrong. We yielded less than the bag of seed potatoes that we planted. The soil was beautiful and rich. We mounded around the growth for the first 6weeks. So disappointing. Any help greatly appreciated.

In future prepare the ground adding manures compost etc., don't over do it though. They WILL NOT require any more fertilising. When young a lightish watering each day or two. When bigger a good watering 2-3 times a week, depending on temperatures. Put your figer in the soil to see if wet or dry and water accordingly.
