Gardening in Colorado is a unique adventure. Like you, I also cannot believe the unseasonably warm weather we are having so far in 2026! We wonder how this will play out for this year's planting season....

The climate, altitude, and soil conditions also all play a role in what grows best here. If you’re ready to dig in and grow your own food, you’re in the right place! I’m excited to share some of the top food crops for Colorado gardens that thrive in our local conditions. Whether you’re a seasoned gardener or just starting out, these tips will help you cultivate a bountiful and healthy garden.

Choosing the Right Crops for Colorado Gardens

Colorado’s growing season and weather is certainly unpredictable. That’s why selecting the right crops is crucial. You want plants that can handle cooler nights, intense sun, and sometimes (usually) dry soil. Here are some of the best crops to consider:

Leafy greens like spinach, kale, and Swiss chard grow quickly and tolerate cooler temperatures. These are our early season friends.
Root vegetables such as carrots, beets, and radishes do well in Colorado’s soil and can be planted early. Fort Collins has a long and storied history with beet farming!
Peas and beans are great for adding nitrogen to your soil and thrive in the spring and early summer.
Tomatoes and peppers love the sunny days but need protection from late frosts. We especially love growing shishito peppers and sweet 100 cherry tomatoes for snacking!
Squash and zucchini are prolific producers and enjoy the warm summer sun.

By focusing on these crops, you’ll maximize your garden’s productivity and enjoy fresh, homegrown food all season long.

How to Prepare Your Garden for Success

Starting with good soil is key. Colorado soils can be sandy or clay-heavy, so amending your garden beds with organic matter is a must. Compost, aged manure, and mulch will improve soil texture and moisture retention.

Here’s a simple preparation checklist:

Test your soil to understand pH and nutrient levels. Did you know the CSU College of Agricultural Sciences will test your soil for you? https://agsci.colostate.edu/soiltestinglab/

Use raised beds or containers if your soil is poor or compacted. If you don;t know, trust us, it's compacted :). We have roto-tilled around here....
Water wisely - early morning watering helps reduce evaporation. We also love using a motion-sensored sprinkler for squirrel deterrant and limited watering for our peach tree!

Remember, healthy soil leads to healthy plants. Don’t rush this step!

What is the 70/30 rule in gardening?

You might have heard about the 70/30 rule when planning your garden. It’s a helpful guideline that suggests 70% of your garden space should be dedicated to crops you and your family eat regularly, while the remaining 30% can be for experimental or less frequently used plants. Or, in our case, as tribute to the local wildlife :)

Why does this matter? It keeps your garden productive and relevant to your needs. For example, if you love fresh tomatoes and kale, allocate more space to those. If you want to try growing something new, use a smaller area.

This rule helps you stay focused and avoid wasting space on crops that might not get used. Plus, it encourages variety without overwhelming your garden.

Tips for Extending the Growing Season in Colorado

Colorado’s high altitude means frost can arrive early in the fall and linger late into spring. But don’t let that stop you! Here are some ways to stretch your growing season:

Start seeds indoors 6-8 weeks before the last frost date.
Use row covers or cold frames to protect young plants from frost.
Choose fast-maturing varieties that produce before the first frost.
Plant in succession to keep your garden producing throughout the season.
Consider container gardening to move some plants indoors if needed.

These strategies will help you enjoy fresh produce longer and make the most of your garden space.

Watering and Maintenance for Thriving Crops

Watering in Colorado requires balance. Our dry climate means plants can dry out quickly, but overwatering can cause root problems. Here’s how to keep your crops happy:

Water deeply but less frequently to encourage strong roots.
Use mulch to retain soil moisture and reduce weeds.
Check soil moisture regularly by feeling the soil 1-2 inches below the surface.
Water early in the day to reduce evaporation and fungal diseases.
Keep an eye out for pests and diseases common in Colorado gardens, like aphids and powdery mildew.

Regular maintenance, including weeding and pruning, will keep your garden healthy and productive.
