Here is a tool that Phyllis Wilburn suggested as a solution for my knee problems. I was complaining about the difficulty of crawling around the garden after Birdseye Pearlwort. She says this tool is her primary weapon combating Common Bittergrass.
The handle is 3 feet long. This tool is designed particularly for work in raised beds or in tight situations where a long handle would be cumbersome. The hoe blade is narrower than a regular hoe. This allows the user to apply more force to the soil. The cultivator side is a bonus. If you are interested, you can purchase the Corona Extended Reach Hoe and Cultivator on Amazon for 17 dollars.
