I've planted potatoes in Michigan much later than the spring dates (late April/early May) that are suggested. They did well and matured before frost. I also have grown potatoes in a small container on a hot patio and that worked, too. I think potatoes can survive alot of stuff and yours will do okay if you keep them watered during hot dry spells and pick off any potato beetles that show up. I'm sure your planting dates for most things are much different than ours.

As for the real planting dates, this was taken from the Mother Earth News about potatoes.

"Since it takes potatoes two to three weeks to emerge from the ground, the earliest you should plant seed potatoes is two weeks before your last anticipated freeze date of 28 degrees Fahrenheit or lower."

Hope that helps.

I have not done it in over 50 years, but as a child in Virginia, most folks planted two crops of Irish potatoes. (Irish Cobblers, Green mountain and Early Rose). First was planted in mid March (St Patricks Day) dug in late June early July. Second planting in mid July, dug at frost. Worked well, depending on the weather, most times the early crop was best, but once in a while the second crop was better. If you nursed your vines through the Georgia summer, you should get a crop. Planting date here for the early crop is mid February. Summers are so hot I have not tried a late crop.

So I guess technically, for a late harvest (before frost) I planted them too EARLY instead of too late? And for a spring harvest they would be considered late? I guess it was probably June when I put them in. \

Well, I;ll keep them watered well, and hope for the best!!!we've had some nice rains lately!!
