I got mine in a Spring swap a few years back & Use it also for planting small trees , & It Can also be used to drill holes in the Ground for Plants ,

I also love this tool great for bulbs , digging small holes in tight places like between roots or rocks. I also use it to get fertilizer deep in the ground to feed large shrubs and trees.

I love my bulb auger (different but works the same). I not only use it for bulbs, but since I have solid clay I have to amend the soil for all of my plants. When I get bare root daylilies, etc., I use my auger to prepare and amend the hole. Breaks down the dirt and works like a charm and I can amend it right in the hole! Love it!
