The only fertilizer that might work in this garden is cement. Often weirdly shaped volcanic rocks are strewn about this seemingly martian landscape. Multihued rocks and earth, with a palette from amber to rust to sienna, are stunning.
It's utterly silent up here and you can see up to four other islands across the white-capped waters. The colors change with the light – pastel in the early morning, rich hues in the late afternoon. Look for rocks oddly perched atop others.
