When to Plant in Santa Fe, NM

Santa Fe, New Mexico, enjoys a growing season that typically runs from the last spring frost on May 15 to the first fall frost on October 1, offering around 139 frost-free days. During this period, gardeners can cultivate a range of crops that thrive in the unique conditions of this region, allowing for both traditional and innovative gardening practices.

The microclimate of Santa Fe, high desert / continental arid, creates conditions that are ideal for specific crops. Plants such as tomatoes, peppers, and squash flourish due to the long, warm days and low humidity, which facilitates growth and ripening. Conversely, crops like lettuce and spinach may struggle during the hot summer months due to heat stress and lower moisture levels, making them less viable during peak growing times.

What to plant now in Santa Fe

In early spring (April), plant hardy greens like kale and radishes outdoors a few weeks before the last frost on May 15. Use row covers if necessary to protect tender seedlings.
As soon as the danger of frost has passed (after May 15), transplant tomatoes and peppers into the garden. These heat-loving plants thrive in the warm soil and bright sun of Santa Fe's high desert climate.
In late summer (late July to early August), after harvesting your tomatoes and peppers, you can plant a second round of fast-growing crops such as bush beans. These will mature just before the first frost on October 1.
As autumn approaches (late September), it's time to harvest remaining crops and prepare the garden for winter. Certain perennials can be planted now, but ensure protection against possible early frosts.

In Santa Fe (139 frost-free days, a moderate season), 38 of 56 planner crops fit outright, 17 get two plantings, 1 crop is perennial.
