By sawing a piece of PVC pipe that can stick up from the ground about 5 inches and have about 7 inches below the ground you can have a great watering/fertilizing gardening helper.

Some gardeners have good luck using buried PVC pipe with holes drilled in it to water their tomatoes. This is a page about watering tomatoes underground with PVC pipe.
I have an idea for watering gardens outdoors but with health problems haven't been able to actually do it yet. If anyone does it, I'd sure appreciate a feedback to let me know how it works!
