Alaska Garden Helper

How might growing conditions change in your part of Alaska in the coming decades?

Choose an Alaska community and see how its growing season has changed since 1980, and how it might change, out to 2099.

Spoiler alert: it may be getting longer!

You can also see graphs of daily minimum temperatures, growing degree days (and how this cumulative heat affects specific crops), and maps of projected hardiness (based on USDA Plant Hardiness Zones).

Graph and map downloads available.
