Drilling Holes in Resin Planters

Drilling holes in resin planters allows plants to grow and stay healthy. Proper drainage is necessary for your plants to thrive.  A container garden that is kept outside receives rainwater in addition to routine watering by the gardener.  This can cause extra water than is actually needed. Inadequate drainage in a planter can make plant roots die because they are not receiving the oxygen they need.  To prevent this from happening, drill holes in the bottom of your planter if there aren’t any already.

Here’s What You’ll Need to Get Started

Resin planter

Hand drill

Artist tape

Drainage Rocks (optional)


Can you Drill Through Resin?

Drilling holes in resin planters is possible without creating cracks. Begin by placing your planter face down on a hard surface. Place artist tape where you would like the holes to be.  This will prevent your resin planter from cracking when you are drilling the holes.  Use a drill bit commonly used for drilling wood.


How Many Holes to Drill in a Planter

A hand drill will work best for this project.  For small to medium planters (4” – 12” in diameter) it’s good to drill a couple of holes that are no larger than ½ of an inch.  For larger planters, 16” and up, drill a couple of holes that are at least an inch in diameter.


Drilling and Drainage

Hold the planter steady as you drill.  Once you have drilled the holes, you can also place drainage rocks at the bottom of the planter to weigh it down and provide extra drainage.
