How to Drill Drainage Holes in Fiberglass Planters

Depending on whether you want to use a fiberglass planter for indoor or outdoor use, it may be necessary to make sure you have enough drainage holes in your planter.
Materials Needed:
Eye protection
Safety mask
Drill
1 inch spade drill bit
Wet/Dry Vacuum
Basic Steps
1. Place planter upright on a flat surface, and ensure the surface where you are drilling is protected. Do not flip the planter upside-down to drill holes, especially if it is painted as it might damage the finish.
2. Mark where you’d like drainage holes in the planter interior. We typically recommend a minimum of two drainage holes. However, the total number of needed drainage holes will vary based on the size of the planter.
3. After marking your interior drainage hole locations, make sure that any holes drilled will not go through the “feet” of the planter.
4. Place the drill bit on the mark, and gently let the drill carve into the fiberglass until you’ve reached through the other side.
5. Use a wet/dry vacuum to clear away any debris.

Why not use a hole saw instead? Wouldn’t it make a lot less dust?
