I am continuing to dig potatoes. The snow peas are planted behind me and this weekend, I'll begin sowing seed for Asian greens in that bed.
@Mauldintiger may want to take notes. It isn't all spud wonderland on this glacial till between two great potato growing regions. Weather did it this year - June weather. Ups and downs, the cool weather didn't quite hit freezing in my garden but blasts of record heat aren't friendly to potatoes.
Luckily, I planted quite a lot of Red LaSoda. I haven't gotten into the Viking Purple yet but the LaSoda plants came in all sizes. I was kinda cringing when I dug some of the smaller plants ... right at 2# for each. Okay, good. First, don't ya know, I dug a couple of big plants. Never got those spuds weighed but we were pleased. Ate 'em right away, too!
There are 100sqft in that bed and 30+ plants. Too many Purple Majesty, the Vikings are in a little separate patch because I didn't find that seed until late. Anyway, the big LaSoda will make up for the low yield Majesty, all purple. There should be about 70# from that bed. The 20sqft of Vikings will give us the 100# of potatoes DW and I can eat before the serious sprouting renders them useless in January.
With all those square feet elsewhere and a basement, why don't you grow a late variety for a longer storage? You might well ask

. Well, I could but then there's the room that the onions and dahlias take up in the basement. And, those basement stairs ...!
At least, I've got early potatoes! (Trying to dig them slowly and eat them quickly so I have less to carry down those stairs!)
