Self Watering Containers & Heavy Rainstorms

Heavy rain can mean trouble for bad self watering container conversions. When I speak to audiences, I get lots of questions about this issue. Specifically, people tell me that they have had “floating plants” in the self watering devices they have purchased commercially. Of course, I can’t comment on that since I haven’t actually seen that happen with any of the devices I have used and I haven’t inspected any of the planters that members of my audiences have discussed.

If, however, that has been your experience, let me assure you that does NOT happen when you use my conversion technique. You see, I completely explain how to create a critically necessary effective overflow hole to prevent just such an occurrence. Think of it as the same device used in your bathroom sink or your bathtub: each has a hole toward the top to prevent the water from spilling over if someone forgets to turn it off when the drain is closed. Essentially the same thing can happen with an outdoor planter when we get a heavy rain of several inches if you don’t have a weep hole or a way for excess water to escape.  My conversion technique accounts for that so that plants do not become waterlogged and oxygen can always flow freely to root systems, a very necessary ingredient for plant health.
