I've had a frog in my garden for 3 years or so and I wonder if anyone
might have some insights?

It seems to be a bachelor, I've never seen 2 frogs. How does it cope
with the boredom?

Can they survive drought? I've been watering regularly round its
favourite spot but I'm going to have to leave the garden for a couple
of weeks and the forecast doesn't look wet. I was thinking of sinking
a plastic container with water into the soil underneath a heather
thereby reducing loss through evaporation. Or will he (she) just dig
herself down till it gets damp enough.
