“Homemade self watering plant containers”
When we first moved to our property, we planted a bunch of trees around the area. We watered them well, but then made drip waterers for them. We took empty containers (juice bottles, milk jugs) and filled them with water. Then we took stips of fabric which were long enough to go near to the bottom of the container and hang over the outside edge of each container. We held the fabric in place with a clothes pin. The water would wick up the fabric and drip onto the plant. We could go around periodically and fill up the containers. We didn’t have to worry about the plants drying up and dying until they could get established.
Your idea is an excellent idea for watering plants, useful for when you can’t be there to do it.
Some also make a small hole or several holes in the bottom and fill the jug with water, that slowly leaks out and waters the soil, works in pots too.
LOL, never did work right for me.
