This method gets water to the root area of the plants. The hydraulic effect of the water makes pushing the wand into the ground effortless. The device is made by cutting off the end of a typical water garden wand as sold in most hardware stores.
Thank you for the suggestion. I like this idea. I also happen to have an old watering wand that may just work.
