Okay kiddo, have you ever seen those little pieces of wood or leaves that people put around their plants outside? That's called mulch! It's kind of like a blanket for the plants.
Mulch helps keep the soil nice and moist, which is good for the plants because they need water to grow big and strong. It also helps keep the soil cool in the summer and warm in the winter.
But wait, there's more! Mulch also helps keep weeds from growing too close to the plants. That's because the mulch forms a barrier that the weeds can't get through.
And here's one more cool thing about mulch: as it breaks down, it adds nutrients to the soil that the plants can use to grow. So it's kind of like giving the plants a little snack.
So that's mulch, kiddo. It's like a cozy blanket that keeps plants happy and healthy.
