Frequently asked questions

When is the last frost in Laketown, UT?

The average last spring frost in Laketown is around May 28, based on 1991–2020 climate normals. That's a median — about half of years see a later frost, so tender crops are safest going out a week or two after this date.

When is the first frost in Laketown, UT?

The average first fall frost in Laketown arrives around Sep 24. Crops still in the garden need to mature before then, and frost-tender plants need harvesting or protection as the date approaches.

How long is the growing season in Laketown?

About 119 frost-free days on average, from May 28 to Sep 24. That favors short-season varieties and transplants for warm-season crops, with cool-season vegetables doing the heavy lifting in spring and fall.

What USDA zone is Laketown in?

USDA zone 6a on the 2023 Plant Hardiness Zone Map. Note that zones describe winter cold, not frost timing — these frost dates are the numbers to plan plantings around.
