Greg, I don't know about your timing there but I've planted my potatoes - probably a little early for this year.
Since you have had success growing Yukon Golds you probably have crowded them just a little or cut them into fairly large pieces so that they didn't try to grow too large and develop hollow heart. You may also think of the crop as one that can come out of the ground in early August at the latest. That may not be true with your other varieties.
I was kind of forced into harvesting some russets last year because they were planted with the early-maturing Yukons and with an early red. They probably could have benefited from another 3 weeks to their season.
You may want to check on the maturity listing for each variety so that you don't make that mistake. Or, separate the varieties so you can choose your harvest dates on something other than Yukon Gold's earliness.
Fingerlings are often late varieties. Reds are often early.
. . . just my 2Ã‚Â¢!
