Seed Potato List and Shopping Cart

We are in the process of changing our shopping cart with the list of seed potatoes. Please check back in August to see the new list.

Next Available Shipping - Nov. 1st

We are finished shipping the spring 2018 seed potatoes and are now collecting orders to ship out starting in November and through the winter. This will be the new crop of seed potatoes that we harvest in September and October. November is a good time to ship the new crop before deep freezing sets in for the winter. This is a good option for those in southern or maritime climates who can plant in January or February. This is also a good option for those who have a good place to store their seed potatoes. The ideal temperature for seed potato storage is 38 to 40 degrees F. At this temperature, the seed potatoes will store for 6 or more months. If the temperatures are warmer, they may only last 3 months. If the temperatures are freezing, they will suffer damage from freezing. Also, having higher humidity in the potato storage will help prolong the storage time.

Winter Shipping

The winter shipping time is December through February. In general we only ship to southern and warmer climates during this time. We will collect enough orders to fill up our trailer and then we'll take the orders down to Phoenix, AZ, where we can ship to southern areas without freezing the seed potatoes. There can be delays during this time of year because we have to make sure the seed potatoes don't freeze. You can check the current news on our website to see when our next winter shipping is scheduled and if there are any delays due to weather.

Early Orders - Shipping in Spring 2019

Many like to order early to ensure that they get the varieties that they want and to make sure that they get the job of ordering done. You are able to order now and specify a ship week later in the year, or a week in 2019 such as March through May. A good time to request shipping is 2 weeks before you plant, and a good time to plant is 2 weeks before your last frost.

Shipping to Idaho

Idaho only allows certified seed potatoes to be shipped into the state. Please choose varieties with "Certified Seed Potato" after the name. Do not choose varieties with only "Seed Potato". We cannot ship garlic or onions to Idaho at this time.

Certified Seed Potatoes

Our Certified Seed Potatoes are certified by the State of Colorado to be disease free. See the CCPGA website. Each certified variety will have the "Certified Seed Potato" designation. A non-certified variety will have the "Seed Potato" designation. All our non-certified varieties are in a 2 to 5 year process of becoming certified.

Naturally Grown Seed Potatoes

Our naturally grown seeds, seed potatoes, and garlic are grown without the use of chemicals, pesticides, fungicides, or synthetic based fertilizers, and are grown using the same philosophy and methods as contained in the Certified Organic Program.


We, at Potato Garden and Ronniger Potato Farm LLC, do not support the concept of GMO's, and will not knowingly acquire, grow, or sell any variety of seeds, seed potatoes, or garlic that contain GMO's (Genetically improved and/or genetically modified organisms).

PVP = Plant Variety Protection

A few of our varieties are Plant Variety Protected, (PVP). They are Canela Russet, Colorado Rose, Mountain Rose, Purple Majesty, Rio Colorado, and Rio Grande Russet. These are cultivars/varieties that are protected under the Federal Plant Variety Protection Act and are owned and controlled by the Colorado Certified Potato Growers Association (CCPGA). At this time CCPGA allows you to buy small quantities of PVP seed from us for your own garden use and also allows you to sell as food through CSA’s, at farmers markets, to restaurants, etc. Larger commercial ventures will need to pay a royalty. You are not allowed to grow these PVP cultivars/varieties for seed stock unless you first get full written consent from CCPGA. Give us a call if you need to grow seed stock and we can set it up. PVP lasts for 25 years.

Seed Potato Shipping

Shipping by UPS or by Mail

We ship Colorado Certified Seed Potatoes in small quantities from 1 to 200 lbs in 5, 10, 15, 20, 25 and 50 lb. boxes. During the checkout process, you'll be able to choose the shipping method and compare costs.

Orders from 200 lbs. to 1000 lbs. are shipped using UPS Hundred weight service. On-line orders for 200+ pounds are adjusted by us after we receive them or you may call for a shipping quote and also place your order by phone. Orders over 1,000 pounds are shipped by Freight. Definitely call us to set up these orders.

Your Shipping Date

Many customers like to place their orders early and have us ship at a later date. During the check out process you are asked for a ship date. As a minimum, please indicate a date that is two weeks before you are able to safely plant. The rule of thumb to follow, for the earliest planting time, is to plant two weeks before your last spring frost. Then of course, you can plant anytime after that, giving yourself at least 3 months growing season before a major fall frost.

Shipping in March through June

If your shipping week falls in the months of March through June, the plan is for you to receive your order later that week or the following week. Occasionally there are delays but we work hard every year to minimize this. Most customers find that shipping 2 weeks before they plant works well. Once received, the seed potatoes will last over a month before they will need to be planted.

Winter Shipping in December through February

During the winter we can ship using insulated boxes going to southern or warmer maritime climates. During extreemly low temperatures we will ship from Arizona so that the seed potatoes stay on a southern route. Because of the logistics of putting this together, delays of one to two weeks may occur. Please note that it does not work to ship to northern and/or colder climates in the winter.

ASAP Shipping

In the months of April and May, we have customers that place their orders and wish that we would ship them now or even yesterday. However, we have thousands of previously placed orders to pack and ship, starting with the earliest ones placed. So if you are placing your order in April or May, the approximate time for you to receive your seed potatoes is 2 to 2 1/2 weeks. You may put ASAP on your shipping date knowing that ASAP means 2 to 2 1/2 weeks for delivery.

How many seed potatoes do I need?

Potatoes in a Pound:

As an average, in 1 pound of seed potatoes, you will receive from 5 to 8 tubers. You can plant all the tubers whole. Or, to get more plants, you can cut a few of the larger ones so that you have at least one eye on each piece. In the picture below, you will see how to make 5 seed potatoes into 10. Use a multiple of 10 to figure out how many pounds you need. Figure 1 lb will plant 10 feet, 2 lbs will plant 20 feet, 3 lbs will plant 30 feet, and so on.

Potential Yield

To figure out potential yield, multiply the pounds planted by 10. So, if you plant 5 lbs. of seed potatoes, you should yield 50 lbs of potatoes. This is a good starting point for estimating the yield, however, many gardeners are able to bring in much higher yields due to great soil and great growing conditions.

Planting instructions are included with each order. You may also request that we mail you a printed catalog or you may download one to your computer.
