When the potatoes have just sprouted and the parts are very small, you can dig out a piece of the buds and bud eyes, and the remaining parts can still be eaten. At this time, the toxins are still concentrated in the bud eyes and nearby parts, and the toxins have not yet spread.

For potatoes with slightly larger buds, the toxin has spread, and the first part of the diffusion is the cortex. Therefore, for this kind of potato, in addition to digging out a piece at the bud eye, you should also cut off a piece near it.

In addition, potato buds do not germinate at the same time. Generally, the terminal buds germinate first, followed by the axillary buds close to the terminal buds, and buds in other parts germinate later. If the top bud grows larger and other buds have not yet sprouted, just cut off the top.
