Supreme Perlite Super Coarse Horticultural Perlite for Potting Soil Mixes, 4 Cu Ft Bag, 2 Pack

Create healthier, better-draining growing environments with Natural Volcanic Perlite, a versatile soil amendment designed to support strong root development and vigorous plant growth. Lightweight and easy to blend, horticultural perlite is ideal for making DIY or lightweight potting soil, improving existing garden beds, and enhancing specialty plant mixes. Use it in orchid blends, succulent and cactus mixes, hydroponic systems, soilless potting media, and aerated indoor plant mixes for tropical plants and aroids. Perlite naturally holds both air and moisture, creating the balanced environment roots need to thrive. Improving oxygen flow while retaining just enough moisture helps reduce conditions that can lead to root rot and soil compaction. This makes it one of the best mediums for propagating plant cuttings and starting seeds indoors, giving young plants the ideal foundation for healthy growth. For a high-quality, well-draining potting mix, use the trusted “1:1:1” ratio—combine equal parts perlite, peat moss, and organic compost. This blend works perfectly for containers, propagation trays, and transplanting mixes. You can also mix perlite directly into heavy garden soil or dense clay to lighten, aerate, and restore raised beds for improved performance. Natural Volcanic Perlite is made from naturally occurring volcanic glass (obsidian) that is expanded with heat, containing no synthetic ingredients. Proudly made in the U.S.A. from 100% domestic ore sources and supported by a domestic labor force, it’s a high-quality growing medium that supports American jobs and manufacturing while helping your plants thrive.
