This soilless substrate provides a growing environment perfect for peace lilies as it offers excellent drainage, nutrient retention, pH balance, and organic matter. Your peace lilies will thrive in our hand-blended potting medium! TIP: Peace lilies are a good choice for low-light spaces because they can thrive in shade or partial shade. They also tolerate fluorescent lights, so if you need a plant friend to liven up your desk at the office, peace lily is a good option. INGREDIENTS: Pine bark, peat moss, perlite, sand, and lime.
