Amending soil with partially decomposed sphagnum moss offers several advantages, primarily improving drainage and aeration in heavy clay soils while enhancing moisture retention in sandy soils. The ideal quantity depends on the soil type, the plant’s requirements, and the specific gardening goals. For example, incorporating a modest amount into potting mixes for seedlings can foster healthy root development, whereas significantly amending a garden bed with heavy clay might require a larger volume.
This practice has historical roots in horticulture, as peat’s unique properties were recognized for creating favorable growing conditions. Its ability to retain water while remaining aerated makes it valuable for a wide range of plants, from moisture-loving shrubs to vegetables requiring well-drained soil. Improving soil structure contributes to stronger root systems, better nutrient uptake, and overall plant health. Furthermore, the slightly acidic nature of peat can be beneficial for acid-loving plants like blueberries and rhododendrons. However, responsible sourcing is critical due to environmental concerns associated with peat harvesting.
