Why’s There Moss On Concrete?
Moss is non-vascular which means they’re without roots. Instead, it uses the tiny threads known as rhizoids to attach itself to concrete and pavers surrounding your home. These rhizoids attach the plant’s body to concrete, allowing it to absorb water and grow on top.
What encourages moss to grow
Moss needs a moist, protected environment to prevent it drying out. The rhizoids will absorb water from this moist environment. Concrete and pavers are made from porous materials, which allow the rhizoids to anchor in places that other plants can’t.
