Chemical garden is kind of soft plant-like structures grown from seed crystal of soluble salts in solutions containing silicates. In this research, we developed a non-scanning X-ray fluorescence spectromicroscopy for time-resolved visualization of its element diffusion process. In the final, the spread rate or sedimentation sequence of different elements can be directly compared and clarified. This may potentially proceed the understanding of chemical garden formation mechanism.
