How long for potatoes to sprout?

Lots of variables but a month is far longer than I have ever experienced. Within 10-14 days is average for me, sometimes earlier depending on weather/rain/planting depth, etc.

I'd carefully dig up one and see what is happening.

Mine took almost a month this year. A few still haven't come up. They're Yukon Gold.

a month doesn't seem like too long for here...cool wet weather

I just dug one up and it has five long shoots about four inches long. We have had cool wet weather too so maybe it's normal? Does it sound okay with what i saw when i dug it up?

Sounds fine to me. I've known them to take a month, particularly when they hadn't done much sprouting before planting.

Depends on alot of factors. Size of eyes, soil type, temps, depth, etc. Worst case scenario mine took almost a month once, and best case, as was already mentioned under good conditions, a week to 10 days. I got anxious once or twice and carefully probed a little into the soil and you can usually find the sprouts.

I did chit them but the eyes were not long by any means, I would say like 1/4 inch. Soil temp was probably too cold and has been too cold lately for much to happen. Depth was about 5 inches.
I guess I should just be patient? The sprouts I saw on the one I dug up today were white about four inches long and there were about five of them on the potato in all directions. Is this what it should look like? Are those the sprouts that poke up out of the soil and begin to produce leaves?
This is my first time for potatoes so I am not sure what to expect.

The potatoes will produce roots before leaves, so by the time the foliage comes up there is a spider of a plant down there. Most of my potatoes are just up, and yesterday I filled in missing spots.

In some years I have had to replant twice because of cold wet weather or voles. I hold back a few seed potatoes knowing I'll have holes to fill.

Aili.... yep, your fine. They'll break through eventually.

Thank you everyone for the information and reassurance!

I was getting concerned no youkon gold potatoes yet but after reading comments i feel better ill be patient

Mine took 1-2 weeks. It's been a month now and they look like this. I'm zone 6b. But they were already sprouted which I'm sure sped things up. I'm sure if you saw sprouts today, they'll come up soon.

Mine took 2 1/2 weeks, and they were pre-sprouted. The soil was still cold.

Yeah, mine aren't up yet after a couple of weeks, but I planted them deep. They'll eventually show up :-)

Mine takes about 2 weeks. I chit them and only cover 2 inches to start with so they get going quickly...then they get more dirt.

Planted on St. Patrick's day with only minimal chitting, mine took about 3-4 weeks to show up this year. Yukon Gold were the slowest at 28 days and Red Norland the fastest at 22 days. Dakota Pearl, Norkotah Russet, and Kennebec were in-between. All are growing well and between 18"-24" tall now.

I only plant yukon gold i just love them it has been a little cold in southern oregon a little unusual for may so im going to be patient, i don't give up easily thanks for the imput everyone

I planted my corn when the soil was warm but not the potatoes i guess i learn something every planting season

They take about a week in my pantry. LOL!

I do have sprouts i peeked and iam hopeful

yeah, my potatoes are finally up Iam so happy

I will send pictures soon
