What Can You Grow in Denver? 

There are tons of veggie varieties to grow at altitude!

When it comes to gardening in Denver, you always have to consider what makes our city so unique: the altitude. 

Certain veggies grow better in the cool season (spring – early summer) while others are more adept to the warm season (mid-summer – early fall). Don’t worry too much about this yet — we’ll go way more in-depth as to the best times to plant in the next section. 

Nevertheless, you should start making your list for each season based on the options listed below, because you’ll probably want to do two cycles. 

Here’s what veggies tend to be most successful for gardening in Denver: 

Cool Season: 

  • Beets, Broccoli, Brussel Sprouts 
  • Cabbage, Carrots, Cauliflower, Chard 
  • Kale, Leeks, Lettuce, Onions 
  • Parsely, Parsnips, Peas, Potatoes 
  • Radishes, Spinach, Turnips 

Warm Season

  • Beans, Corn, Cucumbers 
  • Eggplant, Melons, Peppers 
  • Squash, Tomatoes 

Nothing beets fresh veggies!

Best Practices for Gardening in Denver 

Gardening in Denver is highly rewarding.

Now that we know what grows best at altitude in each season, let’s take you through some best practices for your at-home garden. 

Best Time to Plant 

When it comes to planting early-season veggies, you have to be aware of your final frost date (seedlings don’t like the cold!) 

In Denver this can be a little bit hard to predict, but May 9 is generally accepted to be the safe-zone. 

The risk of frost returns on October 1, so for your late season veggies, you’ll want to make sure you get them in the ground by mid-July at the latest. 

Preparing Your Garden 

Gardening in Denver requires some pretty significant attention, and it all starts with preparing your garden. 

Start by removing all vegetation and weeds that could intrude in your growing area. You’ll then need to till the soil until it is soft and loose, creating an optimal environment for your plants to thrive. 

Colorado soils are high in alkaline and commonly resemble clay. If your soil is especially tough, you might want to introduce more organic matter to achieve an ideal pH level of about 7. To do this, try composting your food scraps then adding the rich soil to your garden! 

Protecting Your Garden 

If you’ve lived in Denver for a while, you’re probably aware that summer storms can wreak some pretty significant havoc. 

To protect your Denver garden from adverse weather and intense summer sunlight, consider investing in row covers, tunnels, windbreaks, and shade cloths. 

Watering Methods 

In most cases, your seed packets will have watering instructions that should be pretty accurate. 

But if your seeds aren’t locally sourced, they might not be factoring in the altitude. Keep in mind that at elevation water evaporates faster; meaning that your plants need more water. 

Keep a close eye on your veggies. If they’re looking dry, give them an extra little drink! 

Opportunities for Community Gardening in Denver

Looking to alleviate some of the pressure and garden in a more community-oriented space?
