Does anyone know how long a cut gourd will last outdoors, in contact with the ground? I had a brain storm (or perhaps a brain f@%*) and want to build a toad condo out of a few of them. I had to disturb a bunch of toads and frogs when I moved some wood by the fence, and when I apologized I promised them I would provide a home for them when I was done.
What I'm thinking is cutting the bottoms off so they'll sit flat (and let the amphibians have a dirt floor), and cutting "doors" near the bottom, and just setting them together on the ground, buried a little for stability, right along the fence. (And yes, I'll probably make one great big one and call it Toad Hall.) But I don't want to do it if they will rot within a few months, you know?
I have a recipe for waterproof, foodsafe gourd dishes (beeswax and stuff) and could use that, though I'm sure it would wear off soon. I would not like to use varathane, but I know it would protect. I'm just a little bit anxious about putting a cut part in contact with the ground. I guess I could avoid that -- dig a little depression to fit the gourd, put sand inside the gourd to bring the "floor" up to ground level, and just have the door very close to the ground. That might be safer.
