Container plants in the rain

A rainy day at Irishgardens today.  Lots of much needed rain.  But what are you supposed to do with the container plants.  Not all containers have drain holes.  I mean sure in a perfect garden all the plants would have the right amount of space, and those in containers would have adequate drainage.

In that perfect garden this would never happen.  Enough rain to fully soak the soil to the point that it collects and makes a pool of sorts.

The lawn would never ever have puddles that form.

 And well established tree's wouldn't nearly drown because the rain is coming down so fast that it can't soak in.

In that same perfect garden the rain barrels would always be full but never over flowing.

So since I don't have that perfect garden I have... a water line that connects to the over flow connection to the greenhouse irrigation system.

And ...

....an umbrella to cover the containers that don't have drainage.  It may not look all that cool and smart but hey it works.  Those 3 containers are no longer swimming in the rain.

So is your garden perfect or like mine and far from it?  What do you do to keep the rain from drowning your plants?  How about your rain barrel if you have one?  Does it over flow on heavy rainy days?
