Turn one of the planters upside down and apply silicone to the bottom.
Line the base of the top planter up with the base of the bottom planter and press down. Let the silicone dry for at least 24 hours. (I discovered, with last year’s table, that using hot glue isn’t a good idea; it melts in the heat. Oops!)
In the earlier incarnation of this side table, I used a patterned tray but, over the course of the summer, the colours faded, so I recommend using a white tray like this one. Push it down into the top of the planter until it feels stable. This tray fits very nicely just below the edge of the planter. You don’t need to use glue here.
Please note that, because of the tray’s handles, the planter will fill up with water when it rains, if it isn’t under shelter. Otherwise, you could use the space underneath to store small outdoor items.
Because plastic pots are so lightweight and because, I will be using my new side table on the lawn mostly, I put four holes around the bottom rim on each of the four “sides” using a small pointy screwdriver and a hammer. If you have an awl, that’s even better. A couple of good whacks for each hole did the trick.
These four holes will allow you to anchor your new side table to the ground using the lawn staples. Barring gale-force winds, the lawn staples should keep the table from toppling in the summer breezes.
If you’d rather use your new side table on a deck or patio, prevent it from tipping in the wind by placing something heavy on it, like this homemade garden light.
Use a small glass bowl, clear glass stones and the top off of a small floral garden stake burrowed into the stones. All of these materials were found at Dollar Tree. This light looks even better at night after it’s been filled up with rain!
