Which type of soil requires the most frequent watering for lawns?

Sandy soil, often simply referred to as sand, has large particle sizes, resulting in significant air spaces between particles. This characteristic leads to rapid drainage, meaning that water passes through sandy soil much quicker than other types like clay or loam. Consequently, grass and other plants grown in sandy soil lose moisture more rapidly and thus require more frequent watering to maintain healthy growth.

In contrast, clay soil retains water due to its smaller particle size and compact structure, which can lead to waterlogged conditions. Clay loam provides a balance between drainage and moisture retention, while sandy loam typically retains more moisture than pure sand. Therefore, sandy soil is the option that necessitates the most frequent watering to keep lawns looking their best.
