Plastic Bottles to Keep a Plant Watered

To help keep our garden plants watered, this year we tried burying soda bottles, with holes in them, beside the tomato, squash and cucumber plants leaving the opening exposed. To easily fill the bottles, we used a flex funnel and the garden hose. The bottles worked very well to help keep the plants watered and we will be doing it again next year. The garden has just about given out and we have removed all the bottles that are no longer used, rinsed them and put them in the recycling bin.
