I have a range of 2" to 5" snails for various sizes of bulbs and seedlings that I plant in the beds around the house. Grafts grown in 4 inch coke pots fit perfectly in the hole made by this snail. Planting a large number of seedlings is much easier than digging them up. If you plant several hundred seedlings several times a year, using a drill with a good 20V cordless drill is the only way.
