Now that our gardening season is starting to wind down with the ADFF quickly approaching, I am looking for a few winter gardening projects to test out. This year was quite dry throughout the summer creating problems with the container plants that easily dried out just a couple of hours after watering. I didn't use the watering globes outdoors but I did use the SoilMoistTM granules on some of the inedible planters. Nothing seemed to help this year so I'm going to start experimenting with self watering containers.
I am going to try a couple of styles of homemade self watering containers. The following video shows the first type I am going to try. This is a very practical set-up that should cost about $5 using recycled materials. It will cost more in potting soil than materials. Potting soil will have a better wicking action than garden soil but I will likely experiment with a homemade soil mixture to use. What I like about this design is the container is large enough for several vegetable varieties. With a bit of modification the container can sit inside a wooden container so it will look nice as well. I will likely use a piece of PVC pipe that we have left over from plumbing repairs rather than try to find plastic water bottles.
