This is the neatest planting tip, to save your back from breaking, every time you dig a hole for planting your tomato plants, that I have ever seen. It is a four foot threaded rod, with a tin, tomato size can, attached to it, by a bolt. The bottom of the can was removed to allow dirt to enter to create the hole. One third of the top was removed to knock the dirt out when you need to empty it. My neighbor invented this to plant his forty patio, bush tomato plants in no time at all. This device doesn't work right now because our ground is like cement because we have had very little rain where we are in Ontario. To make it work well... you would need to wet the area you were going to plant so as not to bust your new planting device, when you stepped on it with your foot to sink it into the ground. Thanks for reading and DIY, build a tomato planter :)
