What can I plant for deer in Idaho?

Idaho sits in the northern planting region (USDA zones 3–7). For fall and winter, plant cool-season crops like cereal rye, winter wheat, oats; for spring and summer, warm-season crops like soybeans (forage type), corn (field corn), sunflowers. Idaho's cold winters and dry summers favor hardy cereal rye and brassicas; irrigate summer plots and plant cool-season crops early.

When should I plant a fall food plot in Idaho?

In Idaho, plant fall food plots late August through mid-September — roughly 45–60 days before your average first hard frost. This gives cool-season grains, brassicas, and clover time to establish before cold weather and the hunting season.

When can I plant a spring or summer food plot in Idaho?

Plant warm-season Idaho plots May into June, once the last frost has passed and the soil warms. Soybeans, cowpeas, and other summer crops need warm soil to germinate well.

What's the best food plot for Idaho?

The most reliable Idaho plot is a cool-season blend — a cereal grain (cereal rye) plus a brassica and a clover. Soybeans (forage type) and other warm-season crops make strong summer plots on larger ground.

What USDA hardiness zone is Idaho?

Most of Idaho falls within USDA hardiness zones 3–7. Zones vary with elevation, so check your local zone for the most precise planting dates.

Soil & lime in Idaho

Whatever you plant, a soil test comes first. Most untouched Idahoground is too acidic for food plots, which locks up fertilizer and stunts growth. Lime to about pH 6.5, then fertilize to the crop's needs. Estimate your lime and read the soil test guide.
