Thread: Worth treating a small hollow crotch for use as an indoor planter?

In the latest round of firewood I found a smallish, hollowed crotch that's too large to fit the fireplace and too... 'full of character' to try to split down.

It's unusual enough that I though to myself "I have to make something out of this but what?" The most obvious thing to use it for is as a planter. Probably for some of our indoor succulents.

(Actually, my first thought was a didgerisax, but practicality quickly overturned that idea. )

Now, as alluded to above, we use a fireplace for heating. This tends to dry out the air very quickly and most of our indoor plants need frequent watering. If I simply stood it in a dish and filled the hollows with potting mix, I imagine it'd dry out even more quickly than usual.

I thought about resizing both hollows so I could simply sit the potted plants directly inside, but that turns it from a planter into a glorified pot-plant holder. For some reason that gripes me. I'm not sure why, but...



Perhaps I could seal the inside with something - epoxy maybe? - but I'm not sure whether that's the way to go either. The question is, what to use that is both cheap and will serve the purpose? It'd take quite a bit of epoxy to seal. Maybe enamel paint?

Or am I just overthinking this? It's just a firewood scrap after all and perhaps just filling it with mix and use it as is would be the best solution?

Suggestions?
