You can do it either way but just pulling up 1 plant is easier. It can be difficult to do a part-harvest without harming the plant if you are inexperienced.

But if you want to try it and assuming you hilled up around the plants as needed, then coming in low down at ground level on the side of the hill with your hand and just sort of feeling around will usually net you a few.

Thanks Dave! I took your advice and pulled up one of my plants and I'm sure glad I did! I had 5 full size potatoes there which completely surprised me (we planted the seed potatoes only 9 weeks ago). I think I will re-plant one of the potatoes as a seed potato to hopefully get another crop in the fall.

Makes me want to go check mine. I have been waiting for flowers, but I havent seen any.

Congrats on your first spuds!
