Pumice is an excellent soil conditioner, as it is highly porous, giving it excellent water and air holding properties. It provides aeration and drainage, as when growing cacti, bromeliads, succulents, or when rooting cuttings. Advantages of using pumice in potting media and garden soils include:
 
1) Provides aeration and drainage to potting mix.
2) Heavier than perlite.
3) 1/3 lighter than sand.
4) It holds vital nutrients in the microscopic surface pores, which helps regulate fertilizer feedings.
5) Loosens the density of heavy clay garden soils, letting in the air and water plants need.
6) increases water retention in light and sandy soils.
7) Holds moisture in the soil, reducing watering requirements, yet pumice will not compact or become soggy.
8) Is inorganic, will not decompose or compact over time, and can be recycled and reused.
9) pH neutral.
10) Does not attract or host fungi, nematodes, or insects.
 
浮石是一种出色的土壤改良剂，因为它具有高孔隙度，因此具有出色的保水和保气性能。在盆栽介质和花园土壤中使用浮石的优势包括：
-浮石的多孔性质使它能够将重要的养分保持在微观的表面孔隙中，从而有助于调节肥料的添加量。在添加到生长介质中之前，甚至可以添加营养。
－对于需要增加通气和排水功能的土壤，例如生长仙人掌，凤梨科植物，多肉植物或生根时的优良改良剂。
-减少了重粘土花园土壤的密度，使空气和水生植物需要。
-增加了在轻质和沙质土壤中的保水性。
—使耕作更容易。
减少结皮，开裂，浸水和收缩溶胀。
-将水分保持在土壤中，减少了浇水的需求，但浮石不会结实或变湿。
-浮石是无机的，因此不会随时间分解或变紧，这意味着它可以连续发挥作用，并且可以回收再利用。
-浮石的pH值为中性。
浮石不会吸引或容纳真菌，线虫或昆虫。
