German Gardeners Discover Horticultural Sand's Power
Gardeners in Germany are turning to horticultural sand to boost their plants' health. This versatile material improves soil drainage, aeration, and is a key ingredient in potting mixes and seed starting mediums.
Horticultural sand, also known as sharp sand or coarse sand, is made from crushed granite, quartz, or sandstone. Unlike sandbox or beach sand, it has larger, rougher particles that allow water and air to penetrate, promoting healthy root growth.
To improve poorly drained lawns, horticultural sand can be raked into holes punched by an aerator. For heavy clay soil, mixing it in makes the soil more porous, enhancing drainage and root penetration. In container growing, a mix of compost or peat and horticultural sand, typically in a 1:2 or 1:1 ratio, creates an ideal potting mix for cactus and succulents.
If horticultural sand is unavailable, it can be substituted with horticultural grit or builder's sand for similar results.
Horticultural sand, with its ability to improve drainage and aeration, is a valuable tool for German gardeners. Whether used to enhance lawn health, transform heavy clay soil, or create ideal potting mixes, it's a versatile addition to any gardener's toolkit.
