Do potatoes still grow after the plant dies?

No, the potatoes (tubers) themselves don't grow bigger after the plant's main energy source (leaves/stems) dies completely, but leaving them in the ground for a couple of weeks allows their skins to toughen (cure) for storage, and they won't sprout new plants immediately unless it's warm, though they can eventually sprout new growth or overwinter if left too long in mild conditions, notes the Growfully blog and the Idaho Potato Commission. The tubers are mature when the vines yellow and die back, signaling the end of tuber growth, but waiting after this (to "cure") is key for keeping them, while harvesting too early means smaller potatoes and thin skins, according to The Country Basket and a YouTube video.

When to stop watering potatoes?

You should stop watering potatoes about 2-3 weeks before harvest, or when the foliage starts turning yellow and dying back, to help the skins toughen and prevent rot in storage.
