Recently, I was given a 1 gallon pot with some yellow water lilies in it. The lilies could be planted near the edge of my pond, but my pond is seasonal and the edge is always changing. There is no point in planting a flower on the edge of a pond when, in a few weeks, the edge will be 10 feet from where the flowers were planted.
Gears churned and a plan was hatched. I'll make a floating planter!
Step 1: Gather some supplies
There are quite a few empty 15 gallon pots at my place from all of the trees that I've been getting at Kurt's Garden. Add in some 45° 2" PVC couplers and some scrap PVC pipe, and I was ready to get crafty.
Cut some pipe
A few quick measurements, and a couple minutes with a hack saw and I had 8 short lengths of PVC to work with.
Make a ring
The couplers and pipe lengths where joined together with PVC glue and I soon had a nice ring that a 15 gallon pot will easily fit within.
Prepare the pot
After cutting the bottom off of the 15 gallon pot, 6 cuts were make down the side of the inverted pot to create some flaps. The flaps were folded over each other, drilled, and then bolted together.
At this point, I put the pot into the PVC ring, added soil to the pot and then tested the contraption in the pond. It sank like a brick.... back to the drawing board!
Make the pot wayyyyy shorter
Obviously the pot filled with dirt was too heavy, so the bolt as undone, the pot was shortened, and then folded and bolted again.
Oh hey look, the new short pot is also sinking.
A few seconds after this picture was taken, I was knee deep in water, pulling the "floating planter" off the bottom of the pond. :/
Fuck it. A 1 gallon pot in the middle of a circular platform shouldn't have any problem floating.... should it?
With some string and a thumb tack, a few circles were drawn on a piece of plywood and then cut. After the cutting, the wood was painted with exterior grade paint an then hung up to dry.
Make a couple mounting brackets
twist twist, twist twist, snip. A mounting bracket is made! Repeat the process, and there are 2 mounting brackets. Being lazy, only 2 mounting brackets were made to affix the PVC float to the platform.
Once the platform and float were attached, the 1 gallon pot was put in the platform's center hole and filled with soil and some lilies (which were a bit eaten by some sheepies), and the planter was placed in the water.
Did I mention that the floating planter actually floats? Well it does, and I am quite pleased with the result.
Now quit reading, and go make something float.
