The sand particles you see on the beaches are often soft, powdery, and velvety. It’s unsurprising given that they are constantly blasted by wave currents. But not every sand is just as smooth. Not every sand is pampered as much as the beach sand. In a stunning contrast to these soft sands, there are sands that are gritty and coarse, often resembling crushed glass. As long as they prick the skin, they are unlikable. But the moment someone pours them into their garden bed, the brittle sands cast magic upon the plants, by preventing waterlogging and boosting growth, as experts revealed in a conversation with Real Simple.

While the pampered beach sand lacks the skill of holding the soil together, this gritty sand helps the soil remain compact and, therefore, improves drainage. Thanks to this grittiness that the soil doesn’t become too heavy or waterlogged. As a result, water and oxygen are able to seep deeper into the soil; otherwise, the plant would have rotted or perhaps died due to a lack or excess of nutrients.

A Reddit user, who goes by the moniker u/SIMPLIFYGARDENING, shared that “sharp sand” proved to be a “game-changer” in propagating his carrots. “I recently experimented with a unique method of growing carrots - using sharp sand with a compost core - and the results were too good not to share,” they shared in a post, adding, “This method has been a game changer in my carrot-growing endeavors. Not only has it made the process more efficient, but the quality of the carrots has been remarkable.”

The Reddit user mixed the sand in a compost core and planted the carrot seeds inside this blend, but Sons suggests that the sand works best when blended with clay-heavy beds or potting mixes, as well as root-cutting compost or seed-starting trays. This, she said, compacts the soil, without compromising on its fertility.
