Illinois’ hardiness zones run 5a to 7b, and Chicago’s frost dates set the planting and bloom calendar most growers get wrong.
Idaho gardens live and die by two things: heat and how little rain shows up when it matters most.
Boise’s mean first fall frost lands somewhere between October 7 and October 21, weeks before Halloween arrives.
Idaho’s planting dates depend on elevation as much as frost, so this calendar shows how to calculate sowing windows from Boise’s NOAA frost data.
Boise sits at 43.57 degrees north, and on the longest day of the year the sun keeps that valley lit for 15 hours and 15 minutes.
A look at which apple varieties suit Idaho’s zones and winter chill, how to pair them for pollination, and when Boise’s frost dates put the bloom at risk.
Hawaii doesn’t have a frost season to plan around, so the calendar that works in Ohio or Vermont doesn’t apply here.
