Potato plants can fall over for various reasons. If, however, they look very healthy, it likely isn’t due to over- or under-watering, nor to disease or extreme temperatures. Sometimes the plants just get leggy, such as if the plants are too crowded, don’t have enough light, received too much nitrogen fertilizer, etc. And, when they reach a certain growth stage, falling over is fairly normal. Be sure to keep hilling them at intervals with mulch (such as straw) or soil, as this helps to give them support and encourages more potatoes to form underground. See the article above for more information. Good luck!
