7-day forecast and frost risk

Pre-emergent

Soil is 49°F at 4 inches (estimated soil temperature, not a station reading). Fall pre-emergent window is mostly past. Next: spring, when soil reaches 50°F (typically mid-April to mid-May).

Fertilizer window

Lawn region: Mountain West and High Plains. Timing only; always follow the product label.

  • Kentucky bluegrass (cool-season): Early fall: Around Labor Day (late August–September); Late fall: Late October–November, before the ground freezes; Late spring: Optional around Memorial Day. Avoid: Early-spring and midsummer feeding (pushes top growth, favors crabgrass).

Plant now

No vegetable planting windows are open this week.

Prune now

No frost-timed pruning windows are open this week.

Your average first frost is Oct 21: skip heavy pruning in the 6–8 weeks before it, because new growth may not harden off in time.

Spring-flowering shrubs are pruned right after their flowers fade, not by date. See the pruning guide.

90% (early: most years still freeze after this)Apr 13
50% (the "average" last frost)Apr 26
10% (cautious: only 1 year in 10 freezes later)May 8

Most gardeners plant frost-tender crops (tomatoes, peppers, basil) after the 50% date, and closer to the 10% date for less risk.

n/a means NOAA did not publish a date at that threshold for this station (usually because it rarely gets that cold).

Vegetable planting calendar for 87083

Dates count from your average last spring frost (Apr 26) and first fall frost (Oct 21). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
