Planting potatoes in Colorado requires careful timing due to the state’s unique climate. Knowing the best time to plant is crucial for a successful harvest. This guide will explore the optimal planting window, considering different varieties and regional variations across Colorado.
Understanding Colorado’s Growing Season for Potatoes
Colorado’s growing season is shorter than many other states, characterized by cool nights and warm days. Understanding this is essential for determining when to plant potatoes. The last frost date is a key factor, as potatoes are sensitive to frost. Waiting until the danger of frost has passed is crucial. Soil temperature also plays a vital role. Ideally, the soil temperature should be around 45°F (7°C) at a depth of 4 inches for optimal potato growth.
Ideal Planting Time for Potatoes in Colorado’s Different Zones
Colorado’s diverse landscape means planting times vary across the state. Generally, late spring (May-June) is the recommended time for most of Colorado, but specific dates vary based on elevation and microclimates. Lower elevations, such as the Front Range, can often plant earlier than higher elevation areas like the mountains. For example, gardeners in Denver might be able to plant in late April or early May, while those in the mountains should wait until late May or early June. Knowing your specific hardiness zone can help you determine the ideal planting time.
Choosing the Right Potato Variety for Colorado
Different potato varieties have varying maturity periods. Early-season potatoes, like Yukon Gold and Red Norland, mature faster than mid-season or late-season varieties like Russet Burbank. Choosing the right variety for your area and desired harvest time is essential. If you have a shorter growing season, opting for early-season potatoes is often the best strategy.

When should I plant early-season potatoes?
Early-season potatoes can be planted as soon as the soil is workable and the danger of frost has passed.
When should I plant late-season potatoes?
Late-season potatoes require a longer growing season and should be planted earlier to ensure they mature before the first fall frost.
Preparing the Soil for Potato Planting in Colorado
Well-drained soil is crucial for potato growth. Amending the soil with compost or other organic matter improves drainage and provides essential nutrients.

Potato plants thrive in slightly acidic soil with a pH between 5.0 and 6.0.
Caring for Your Potato Plants in Colorado
Once planted, potatoes require consistent watering, especially during dry periods. Mulching around the plants helps retain moisture and suppress weeds. Hilling up soil around the stems as the plants grow protects the developing tubers from sunlight and encourages more potato production. This also protects the potatoes from turning green, which indicates the presence of solanine, a toxic compound.
Harvesting Your Colorado Potatoes
Harvest time depends on the potato variety and the planting date. Early-season potatoes can be harvested as soon as the tubers reach a desirable size, typically around 70-90 days after planting. Late-season potatoes require a longer growing season, usually 100-120 days. For more information on the best planting times, check out when to plant potatoes in colorado. Signs of maturity include the plant’s foliage beginning to die back.
