Vermiculite Supplier in Manila

Vermiculite and perlite are both mineral amendments used to improve soil, but they work in opposite ways. Vermiculite is a hydrous phyllosilicate mineral that expands into accordion-like layers when heated. It absorbs and holds moisture, making it ideal for plants that need consistent dampness. Perlite is a volcanic glass that expands into porous white granules. It promotes drainage and aeration by creating air pockets in the soil. Use vermiculite when you want to retain more moisture in your soil mix, such as for seed starting, tropical plants, and vegetables that prefer even watering. Use perlite when you need faster drainage, such as for succulents, cacti, and orchids. Many gardeners combine both in their potting mixes to achieve balanced moisture retention and drainage. A common blend uses 10 percent vermiculite and 10 percent perlite in a standard potting mix.

Vermiculite is one of the best materials for starting seeds because it retains moisture while remaining lightweight and sterile. To start seeds with vermiculite, fill your seed trays or small pots with a mix of equal parts vermiculite and coco peat. Moisten the mix thoroughly before sowing seeds. Press small seeds gently into the surface and cover with a thin layer of fine vermiculite. For larger seeds, create a small hole at the recommended planting depth and cover with vermiculite. The moisture-retaining properties of vermiculite keep seeds consistently damp without waterlogging. Its light, fluffy texture makes it easy for delicate seedling roots to push through. Vermiculite is naturally sterile, which reduces the risk of damping-off disease that kills young seedlings. Keep your seed trays in a warm spot with indirect light and mist gently when the surface begins to dry.
