Whisky barrel planters are a perfect way to add charm and growing space to your porch or deck but they tend to be heavy and difficult to move around. Plus, without proper drainage – they’ll rot out quickly and likely only last one growing season. This project will create an improved barrel planter that is lighter in weight and has a built-in drainage system to ensure longevity.
Time: 2.5 hours
Skill Level: Easy
Estimated Project Cost: $60.00 (as shown)
(1) 3/4″x10 foot PVC pipe, cut to (4) 12 inch lengths
Hack Saw or Saws-all
Plastic Sheet (in case of spills or leaks)
(1) Large Whiskey Barrel Planter (26 inch diameter)
(1) bag of Sika Post Fix
(1) 10.1 fl.oz. cartridge of Sikaflex Construction Sealant
(1) 32 qt bag of Potting Mix
Insert the sections of the PVC piping in the pre-drilled holes in the bottom of the bucket. Using the Sikaflex Construction Sealant, seal around the bottom of the barrel and the PVC pipes.
Follow the instructions for the Sika Post Fix and add the package of expanding foam as shown in the video below:
Allow the Sika Post Fix foam to expand and rise.
After two hours, the foam will be fully hardened. Cut the PVC pipes flush with the foam.
- Add soil, flowers and water.
- Planter is now half the weight of a soil filled planter.
- Foam is completely safe for plants after cure and will not absorb water.
