Benefits of Crushed Glass in Potting Soil

A recent study reveals that using a mixture of 50% crushed glass and potting soil leads to faster growth rates compared to using 100% potting soil. The incorporation of crushed glass improves soil aeration, allowing more oxygen to reach plant roots, which is essential for healthy growth. Additionally, the glass prevents fungal growth that can often occur in organic-rich potting soil. This suggests that incorporating recycled materials, such as glass, into horticulture practices can enhance the effectiveness of potting mixtures.
