Watering Your Strawberry Jars

I cut a piece of scrap plastic, ABS, PVC, or CPVC pipe equal to the depth of the soil in the container. The diameter of the pipe can be varied based on the size of the container and the water requirements of the plants used. Using a drill, I make holes at regular intervals down the length of the pipe. If you don't have a drill, you could cut small notches with a saw.
You then hold the pipe in the center and fill the jars with your potting medium. Potting medium that is slightly moist is best so that it is compressible and easier to wet after planting. If you have a problem with the soil falling into the watering pipe, you can use a dowel or smaller piece of pipe inserted into the watering pipe till you've firmed the soil and planted the jar. Watering is now a snap. Fill the tube, even if you need to hit it more than once, there is no erosion. Drizzling a bit over the outside and surface will help, but most of the water comes from within. We've used this method with success for many years even on our homemade planters.
