How to Plant Potatoes in Colorado

Potatoes are a versatile and nutritious vegetable that can be easily grown in Colorado’s unique climate and soil conditions. Whether you’re a seasoned gardener or a beginner, planting potatoes can be a rewarding and satisfying experience. In this article, we will guide you through the steps of planting potatoes in Colorado and answer some frequently asked questions to ensure a successful harvest.

Choosing the Right Variety:

Before you start planting potatoes, it’s essential to choose the right variety that suits Colorado’s climate. Some popular potato varieties that grow well in Colorado include ‘Russet Burbank,’ ‘Yukon Gold,’ ‘Kennebec,’ and ‘Red Pontiac.’ These varieties are known for their adaptability to cool climates and resistance to common potato diseases.

Preparing the Soil:

Potatoes thrive in loose, well-draining soil with a slightly acidic pH level between 5.0 and 6.0. Start by removing any weeds or rocks from the planting area. Colorado’s soil is typically alkaline, so you may need to amend it with organic matter like compost or peat moss to lower the pH level and improve drainage.

Planting Methods:

There are a few different methods you can use to plant potatoes in Colorado:

1. Traditional Hilling Method: Dig trenches about 6 inches deep and 12-15 inches apart. Place seed potatoes, which are small potatoes or potato pieces with at least two “eyes,” in the trenches about 12 inches apart. Cover the seed potatoes with 2-3 inches of soil and water well. As the plants grow, gradually add soil around the stems to create mounds, or hills, which protect the developing potatoes and encourage higher yields.

2. Raised Bed Method: If you have heavy clay or poorly drained soil, consider planting potatoes in raised beds. Build a raised bed about 8-12 inches high and fill it with a mixture of compost, peat moss, and garden soil. Plant the seed potatoes as described above and water thoroughly.

3. Container Method: If you have limited space, you can grow potatoes in containers like large pots or grow bags. Fill the container with a well-draining potting mix and plant the seed potatoes about 4 inches deep. As the plants grow, add more soil or mulch to cover the stems, leaving a few inches of foliage above the soil. Make sure the containers have good drainage to avoid waterlogged soil.

Watering and Care:

Potatoes require consistent watering throughout the growing season. Keep the soil consistently moist but avoid overwatering, as it can lead to rotting tubers. Water deeply once or twice a week, depending on rainfall and temperature. Mulching around the plants can help retain moisture and suppress weeds. As the plants grow, watch out for common pests like Colorado potato beetles and apply organic pest control methods if necessary.


Depending on the variety, potatoes can be harvested 70-120 days after planting. When the plants start to yellow and die back, it’s a sign that the potatoes are ready for harvest. Carefully dig around the plant with a garden fork or shovel, being cautious not to damage the tubers. Allow the newly harvested potatoes to cure in a cool, dark, and well-ventilated area for about two weeks before storing them.
