When to Plant Veggies in Denver

Denver, Colorado is known for a thriving garden season due to relatively mild temperatures and abundant sunshine. The region is also favorable for growing a wide range of vegetables for harvesting all summer and into the fall. Denver is said to have one of the longest growing seasons, but when is the best time to plant vegetables in the Mile High City?

Earlier Spring Planting

When the snow melts and early spring arrives, Denverites can start planning and planting their gardens. April marks the best time for planting hearty and cold tolerant veggies such as:

  • Peas
  • Broccoli
  • Spinach
  • Asparagus
  • Potatoes
  • Swiss chard
  • Carrots

Late spring/ Early Summer Planting

As the spring weather warms and the snow melts away, slightly warmer veggies such as beans, beets, and onions can be planted in late spring and early summer. Denver’s warmer late spring and early summers allow for tomatoes, peppers, squash, cucumbers, and melons to be planted.

Late Summer Planting

The late summer and early fall season brings warm days, cool nights, and plenty of sunshine to Denver. This provides an ideal environment for cool weather veggies such as lettuce, Brussels sprouts, cabbage, and kohlrabi that can tolerate cooler temperatures.

Extending the Seasons

No matter when you are planting your veggies, Denverites have the advantage of extending their growing season with a little extra insulation or protection from the elements. By the time all the days in Denver begin to get cooler and shorter, a hoophouse, cold frames or row cover over cooler weather veggies can keep your garden growing until the first frost.

Whether you are a novice gardener or have many years of expertise, Denver offers an extended growing season that almost any veggie lover can enjoy. With proper planning and preparations, anyone can enjoy a thriving vegetable garden in the Mile High City.
