Bulbs can be planted once soil temps are below 60

The bulb auger sounds great! I find it very time-consuming to plant bulbs so deep in the ground by hand.

"Bulbs can be planted when the soil temperatures are below 60 degrees, which generally occurs in September and early October," according David Robson, horticulture educator for the University of Illinois Extension.

Bulb augers fitted to electric drills make planting individual bulbs easy, or a large area can be dug out for mass planting, according to the Extension. When putting the bulbs in the ground, add a handful bonemeal and 1 rounded teaspoon of 10-10-10 fertilizer per square foot to encourage strong plants and good rooting.
