I'd like to hang a hammock in a small garden. There is one wall that can carry it, but on the other side it would have to be a stand-alone pillar.
What's the most efficient technique to erect a pillar that would not be toppled by the lateral pull just so in the ground?
I thought about a metal rod with a large-enough flat foot that would be buried under the ground, but the garden is small, so I think it might not fit or disrupt the whole place. The other thought I had was a metal rod standing in a hole filled with concrete, but I fear the hole and concrete would have to be huge.
Is there an elegant, light-weight way how to have a strong enough stand-alone pillar in the ground?
