Why not add a couple more drainage holes?

I had hole cutters on a drill bit & I can't remember if I got it back after a nbr used it. The plastic might shatter. I have some that are past it...but one planter has an apple tree in it on the patio + apples. The white /cream colour is a dark scratchy grey....
I have a wicker hanging basket that will disintegrate if I touch it. It had carnations in but is a saxifrage zone

Try this: Hold a screwdriver over an open flame until it turns red hot. Have pot next to you upturned. Pierce the red hot screwdriver through the plastic bottom of the pot - goes through like butter.

Go get your power drill back.

I daren't do that to OH's screwdrivers but I do the same with an old fashioned metal meat skewer. Takes a bit longer but works just as well.

Sounds like Bringing Back The Spanish Inquisition.

That's just what it would be if I did that with His screwdriver....

I use my own -

We used to have red hot pokers. Kids would use them as spears & the plant just thrived....

I bet you couldn't make holes in pots with them though!
