Is marble prone to staining in outdoor tree boxes exposed to pollen?

Marble is a luxurious and elegant natural stone often used in outdoor settings, including tree boxes. However, its porous nature makes it susceptible to staining, especially when exposed to organic materials like pollen. Pollen, along with moisture, can seep into the stone's surface, leaving yellowish or brownish stains over time.

To minimize staining, regular cleaning with a pH-neutral stone cleaner is recommended. Sealing the marble with a high-quality penetrating sealer can also provide a protective barrier against pollen and other contaminants. Avoid acidic or abrasive cleaners, as they can etch the surface and worsen the problem.

For long-term maintenance, consider covering tree boxes during high-pollen seasons or opting for darker marble varieties, which may hide stains better. With proper care, marble can remain a stunning choice for outdoor tree boxes despite exposure to pollen.
