How do stone outdoor chairs impact the pH of surrounding soil?
Stone outdoor chairs, especially those made from limestone or other calcareous materials, can gradually alter the pH of surrounding soil. Over time, rainwater and weathering cause minerals in the stone to leach into the ground, raising the soil's alkalinity. This effect is more pronounced in acidic soils, where the neutralizing action of calcium carbonate can be beneficial. However, in already alkaline soils, it may hinder plant growth. To mitigate this, consider using sealed stone furniture or placing chairs on gravel bases to minimize direct soil contact. Regularly testing soil pH helps maintain a balanced garden environment.
