Not sure, but it shouldn't reduce the yield. I've seen rows of potatoes that basically never flower and have standard harvest.

How long were they open? Potato flowers are hardly ever fertile and will just fall off after a while... Maybe a week of flowers that open and drop until they've all flowered, though the time frame is just a guess. FWIW, I have one variety that finished flowering about a week ago, and another variety that's about halfway through the flowering period, and a third variety that hasn't flowered yet.

When they flower, you can use that as sign that the potato tubers are starting to form, and about a week after all the flowers have dropped is approximately when you can dig around the base of the plants and expect to find new potatoes that you can harvest, tough you need to be careful not to break off the smaller spuds that are just developing, and, of course, doing this will reduce the main harvest of the full sized potatoes.

Heat would be my guess too, which is not good since it also inhibits tuber formation.


Yukon Gold flowers well and is somewhat fertile. Kennebec might be a different story and be one of the varieties that doesn't flower much.

Sorry, I got my facts wrong. I was remembering Yukon Gold for something else.


Apparently it does not flower well. Quote from potato breeder Tom Wagner

"...Yukon Gold potatoes. Most of the time the variety does not make flowers and I have to scan a field of Yukons to find a few flowers"
