Did you know that plants need the same things as you to grow and survive? In How Plants Grow for Kids, you'll learn about four of the main things plants need to grow. These “four central elements” are soil, sunlight, air and water. What does each of these things do for plants? Let's find out!

Plants will find most of the nutrients they need in the soil. These nutrients include nitrogen, phosphorus and potassium. Nitrogen is what makes plant leaves green. Phosphorus contributes to the overall health and strength of the plant and its root system. Potassium helps the plant fight disease. The soil also supports the plant and helps prevent it from falling over.

The next element is sunlight. The sun produces energy through light that plants can use to make food. The leaves are the part of the plant that carries out this process, photosynthesis. Without this process, plants would not be able to survive. However, too much or too little sun can be harmful. Another important element is air. From the air, plants receive carbon dioxide, a component that, like sunlight, contributes to the process of photosynthesis. Carbon dioxide also allows plants to use energy from the sun to feed and grow.

Finally, plants need water. Water is necessary for the plant to grow healthy and strong. The water a plant receives helps guide nutrients to the plant through its roots, stem and leaves. Plants may be receiving too much water. Too much sun harms plants, and overwatering can produce the same results. A few other things plants need are temperature and space. Proper temperatures ensure that plants do not die from extreme heat or cold. And plants need enough space to grow to their full size. Overcrowding can cause disease or prevent plants from getting enough air.
