Harvesting Potatoes

Tuesday, October 2nd, 2012

Q. When I told someone from Idaho that I thought potatoes were continually being planted and harvested all year long, he laughed at me. Isn’t that true?

A. If you account for all of the countries that grow potatoes in the world, you might win the bet. Somewhere, at any given point in time, potatoes are probably being planted and likewise harvested. Harvest usually happens once a year, and most areas only get one crop. In Idaho, we can store the potatoes grown and harvested between August and October in large potato cellars, sometimes referred to as a potato shed. This is where the potatoes are taken out of storage and washed, then sorted into consumer bags or foodservice cartons for fresh consumption. Below is a picture of what Idaho® potatoes typically look like in storage. These facilities can be as long as a football field! The 2012 harvest looks like it will be a nice crop—about 12 billion pounds of potatoes will be dug up in Idaho this season unless Mother Nature intervenes.

Growing Potatoes

Q: We want to grow Idaho® russet’s in our garden here in eastern Oklahoma. We are much warmer and more humid than Idaho and we wonder if the potatoes would do well here. Also, I have been unable to find where I can buy starts.  Do you know of any garden companies that sell them?

A: Only Idaho potatoes come from Idaho. As far as growing potatoes in your state… nearly all states grow potatoes, I’d check with the land grant college there or with the State Department of Agriculture.

When are Idaho Russet Burbanks Harvested?

Friday, December 30th, 2011

Q. When are Idaho russet burbanks harvested?

A. The Idaho Russet Burbank variety is typically harvested from mid-September to mid-October each year. It is a late maturing variety.  Others such as the Russet Norkotah from Idaho grow to maturity earlier and are typically harvested in mid-August to mid-September. Idaho rules and regulations require that bagged or carton potatoes carry the variety designation right on the package or noted on a quick lock enclosure tag on bags sold in retail outlets such as grocery stores. Potatoes are harvested once a year, then stored for consumption throughout the year. So, in November you may see both varieties mentioned earlier being sold side by side.

Potato Growing 101

Monday, July 18th, 2011

Q. I am a first time potato grower, with some success.  I have a very small patch, about 40 plants.
When do I harvest the potatoes to get the best yield?  Do I dig them all up at the same time?  Do I wash them before storing “in a cool, dry place”?  How does one “grow” seed potatoes?

A. For this type of question I think we need the expertise of the Idaho Potato Commission’s Industry Relations Director, Todd Cornelison.  Todd, any advice???

Absolutely, I’d be glad to share my knowledge!

My name is Todd Cornelison and I work for the Potato Commission, however, prior to that I was involved in a farming operation most of my life.

Potatoes normally grow in a 110-120 day season depending on the variety you planted. Like most plants, the longer they grow, the more yield you will get. However, you need to choose your harvest time based on the size of the potatoes you desire. You do this by occasionally digging up a plant and looking at the tubers under it. If the plants were planted at the same time, most of the potatoes under the plants will be about the same size. Now, when I say same size, I don’t mean all of the potatoes under the plant will be the same size, I mean you will have approximately the same size profile under each plant. So you look at the biggest potatoes and then the others to determine if your crop has the profile you desire, if so, begin your harvest. If you are not sure, you can harvest your plants at different times and give yourself different size profiles. Keep in mind that the bigger potatoes get, the rougher they tend to be, so it is difficult to get really uniform large potatoes.

Your best bet on storage is always to leave them as they were harvested, i.e. with a little dirt still on them. When you wash a potato, it tends to “wake” it up and it wants to grow again, that’s why potatoes sprout. You can limit this by not washing the potato, but you cannot stop it. Farmers here in Idaho manage their storages all winter long with a very precise mixture of humidity and cooling to keep the potatoes dormant. You probably don’t have that luxury so it is going to be very difficult for you to keep all of your potatoes until you can grow next season. This all depends on your growing area obviously.

As far as seed goes: you have already grown it! A potato sprouts, so if you put that potato back into the ground, it will produce another plant. Now keep in mind your seed will not be as healthy as the seed we use in Idaho because we limit the amount of generations that seed can go through prior to planting. In other words, potatoes cease to be seed after planted back a few years in a row. That doesn’t mean they won’t grow, it just means they don’t tend to be a virile as they were when they were younger. Your problem is going to be managing the potato sprouting during the offseason. Without proper storage and ventilation, a potato will sprout and get spongy and wrinkly, while this potato will probably still grow a plant, the plant will probably not be overly healthy. However, if you can manage the sprouting and storage over the offseason, your potatoes will grow when you put them back into the soil.

I hope this clarifies some of your questions.

Thanks
