Knowing the growing zones and conditions is key to ‌growing potatoes in Utah

Though it is semi-arid and mountainous, it has a range of climates and planting zones, so you will need to check what your local conditions are.

The USDA plant hardiness zones in Utah range from:

  • 4a: covering minimum average temperatures between −30 °F (−34.4 °C) and −25 °F (−31.7 °C)

to

  • 9a: covering minimum average temperatures between 20 °F (−6.7 °C) and 25 °F (−3.9 °C)

For the parts of eastern Utah known as the rain shadow, rain is limited, but the State gets most of its rain from fronts moving in from the Pacific Ocean.

And, of course, the winter months bring in snow, especially along the Great Salt Lake.  

The varied conditions mean that, depending on availability, you can successfully cultivate most potato varieties in the State of Utah.

As long as your soil temperature is above 50°F (10°C), you should be fine.

However, some tips and tricks for growing potatoes in the desert will always prove valuable.

How to grow potatoes in Utah

Growing potatoes in Utah is not much different from growing them in the other 49 states.

As with most garden cultivation, you’ll get out what you put in, and using the well-adapted varieties shared above should get you great results.

Here are the basic steps.

1. Prime your soil

Even if you are living in a dust bowl, you can prepare a raised bed with well-drained soil with plenty of organic matter to feed the potato.

A sandy Utah soil that drains well will be on your side.

You can prep your Utah soil with liquid fertilizers or a one-inch layer of rich compost.

2. Prep your potatoes

Grow whole or partial potatoes in your backyard.

For the best results, get certified seed potatoes as they are more likely to be disease-free.

If you cut a potato into pieces, each piece should have at least one eye.

3. Chit your potatoes

You can speed up the growth of your potatoes using a process called chitting.

This involves simply leaving them out in a cool, dry place.

The light exposure will stimulate their sprouting, which can help them grow early varieties. 

4. Plant out your potatoes

You’re now ready to get those potatoes in some decent soil.

Plant your rows of seed potatoes, at a depth of between 4 and 6 inches with the seed potatoes being no less than 30 inches apart in a row.

Aim for planting only 10 seed potatoes per 100 square feet of your garden. 

5. Hill up the soil on your potato plants as they grow

Hilling up soil around your potato plants feeds them, supports the stem, and provides room for the developing tubers.

Create your mounds within four weeks of planting.

6. Consider mulching your potatoes

Mulching is a great way of preventing weeds and keeping warmth and moisture in the soil.

Black plastic can keep the heat in when growing earlies but you can also use grass clippings or straw as an effective mulch.

7. Control your watering

Overwatering can be a problem, especially in cooler weather.

Too much water increases the potential for blight and can give rise to waterlogged potatoes that rot easily.

After the most intense summer heat has passed, cut back on the water for your potatoes.

Err on the side of caution by watering your potatoes with no more than 2 inches of water per week. 

8. Harvesting your potatoes

Potato pests and diseases in Utah

Utah State University advises that these are the most common pests and diseases in the state:

Colorado potato beetle

These little yellow and black beetles can quickly defoliate your potatoes. The best method of control is hand-picking.

Flea beetle

These are small and shiny black beetles that target young potato plants, reducing their vigor and yield. They respond to insecticides.

Early blight

Even in desert climes, over-watering and watering late in the day can precipitate the appearance of black spots and rot on the leaves.

Manage blight by removing affected leaves and reducing watering.

Tips for growing potatoes in the desert

Growing potatoes in the Utah desert is not much different than growing them in more temperate climes.

There may be some advantages as the weather is drier, making it less easy for blight to take hold.

Here are some quick tips for growing potatoes in the desert.

Containers help you get conditions just right

By growing your potatoes in containers, you can achieve perfect soil conditions, even if you live in a dust bowl.

You can get a good crop of potatoes by growing in hessian sacks, empty bins, and even an old paddling pool!

Mulch, mulch, mulch 

Achieving the full sun your potatoes need will be no problem in the desert, but keeping your potatoes adequately watered may be.

A decent mulch makes all the difference in arid conditions as the water you add is retained in the covered soil. 

Try the hay method

It sounds crazy, but you can grow your potatoes in a hay bale!

Simply plant the potatoes deep in the hay bale and water.

You can enjoy a great crop of disease-free potatoes fed by the decomposing hay bale.

You may ‌get a longer growing season

If you start your potatoes early in Utah, you may be able to enjoy ‌up to four plantings in the year, because of the warmer desert temperatures.

Start your early potatoes, as early as the beginning of March depending on your last frost date. 

Rounding up

As you can see, growing potatoes in Utah does not have to be a challenge.

With well-adapted potato varieties available, you can easily get growing and enjoy your delicious crop!
