It All Starts with a Seed

Trees germinate, or grow, from seeds. However, you just can’t put a tree seed on your kitchen table and watch it grow. Trees, like all living things, need essential elements and nutrients to survive. These include, water, light, warmth, and air. When all of a tree’s needs are met, something inside the seed will trigger, and it will begin to grow. It sends one root down and a stem up. The root will take in valuable nutrients, including water, from the soil, and the stem, which will produce leaves, will take in the sun’s light. Trees use the sun’s light in a process called photosynthesis, which is the fancy term for trees making their own food.

The Growth Process

Once photosynthesis has begun (with the help of chlorophyll, the substance that makes the leaves green), the tree is well on its way to health. With energy from the sun, water, soil nutrients, and carbon dioxide from the air, the tree will make sugar and oxygen. The oxygen is a by-product of this food-making process and is thus released into the air. The tree uses the sugar it makes to grow, which we see in leaves, bark, wood, roots, flowers, and fruits.

The Growth of Branches

Trees grow taller when they add new cells to the ends of their branches. Barks get thicker in the same way. Scientists call these new cells xylem and phloem that run throughout the entire tree, similar to our blood vessels. Xylem and phloem carry water and food throughout the tree, delivering these nutrients that your tree needs to survive. Halo Tree Services in Macomb notes that in between the xylem and phloem is a layer called the cambium, which is only one layer thick. It’s job is to make new xylem and phloem. The thick outer layer of the tree is called the bark, and its job is to protect the tree from injury.

The Growth of Roots

At the same time that the tree is growing upwards, it is also growing downwards. The job of a tree’s roots is to anchor the tree into the soil, as well as to absorb nutrients that the tree needs to continue to make food. A tree’s roots grow at the tips, just like a tree’s branches do. Even with huge trees, the majority of a tree’s roots are found near the top of the ground. This is so the tree can catch the most water when it falls. A large tree can take in hundreds of gallons of water in a day, which it uses in photosynthesis. However, the majority of this water is transpired, or released back into the air.

What are Growth Rings?

Most people know that you can tell the age of a tree by counting its growth rings. But what exactly are these growth rings? Most trees do not grow all year, at least those in Michigan do not. They grow really fast in the spring and summer when the rain is at its greatest. When a tree grows, it lays down a layer of light-colored wood. Halo Tree Services in Macomb notes that the growth rate of trees then slows down considerably throughout late summer and early fall. Here, the tree lays down a darker, denser type of wood. The contrast in the color shows up as rings around the circumference of a tree. Hence, if you count the one dark and one light ring as one, you get one year of growth of a tree. By counting the rings, you can then tell how many years old that tree is when it was cut down.

Scientists use a tool called a borer that removes a small core from the tree to tell its age without having to cut it down. Scientists can learn a lot from a tree by how big its growth ring is, such as when droughts took place, if there was a fire, or when there was abundant growth. The growth ring of a tree is bigger when there’s a healthy growing environment with lots of water and sun.


Without trees, our world would be a dull place, not to mention it would be hard to breathe without trees producing oxygen for our world. Halo Tree Service in Macomb is passionate about keeping trees healthy. By investing in tree trimming services, you are removing dead branches that your tree does not need, allowing it to focus on the healthy branches. By investing in tree pruning services, you are freeing up space for your tree to grow by making its branches and leaves less dense. By investing in tree stump removal, you are helping to clear the ground for another tree to take the place of the one that died.
