The Four Plant Ingredients
Plants need four things to grow big and strong: soil, water, sunlight, and air. Think of these as a recipe — if you leave out one ingredient, the plant will not grow well!
Soil is like a plant's home. It holds the plant's roots in place and is full of nutrients — vitamins for plants! Good soil is dark, crumbly, and full of tiny creatures like worms that keep it healthy.
Water is a plant's drink. Plants sip water through their roots, and it travels up the stem to every leaf and flower. Without water, plants wilt and droop, just like you feel tired when you are thirsty.
