The Importance of Roots

Healthy roots are necessary for your growing success. Learn about the importance of roots to plants and trees, and how to keep them in good shape.

In this article, we discuss the role roots play in a plant’s life, how to keep them healthy, and what to do to prevent and protect against potential problems. Many of our berry plants, flowers, and other garden plants are grown in pots in our greenhouses. We maintain these plants at a certain height to avoid damage in shipping, but the dense root systems are the masterstroke – this is true of any plant or tree you want to have success growing.

About Stark® EZ Start® Pots

This program, that yields our potted trees, utilizes a unique design: bottomless pots. As the roots grow out the bottom, the root system is naturally air pruned. The tap root is severed, and more new feeder roots are forced to grow within the container. This creates a dense mass of roots, allowing the trees to be transplanted and established more quickly and easily than they would as bare-root trees. Both potted and bare-root plants and trees rely on healthy root systems to grow well and become established in your yard.

About Roots

Roots play an important role in a plant’s nutrient intake, similar to its leaves with photosynthesis — a system of converting light energy into food for your plant to feed on. While it is the leaves that enable this process, the roots help to bring soil nutrients through the vascular system of the plant and store nutrients during dormant periods. When transplanting a new plant, many people forget about the roots and worry that a lack of top growth (the part that stays above the ground) means that the plant is too small or weak to survive. In fact, it’s just the opposite!

Long elaborate leafy tops are not ideal for transplanting, since they require sustenance for continued growth. This puts additional stress on a new plant, because it really should focus its energy on getting established at planting time. Even if top growth isn’t excessive, having a mass of strong, healthy roots will encourage a plant to put on more top growth once it becomes established in its new environment. That’s also the reasoning behind why we pre-prune our bare-root fruit trees before shipping them out to you. To create that necessary balance.

Common Root-Related Issues

Just as it is essential to understand the importance of healthy roots, it is also necessary to recognize symptoms of unhealthy roots. Roots transfer nutrients and water to the rest of the plant and, if there is an issue with the soil, you will usually notice a change in the top growth of your plant.

One sign of a potential problem is the yellowing of leaves — a decrease in the normal green color of leaves of plants can be caused by many root-related problems like a lack of soil nutrients, incorrect pH (blocks intake of necessary soil nutrients), over-watering, and more.

Even though roots are located under ground, they still require air to remain healthy and free of fungi and water molds. If a plant’s location does not drain properly, it will retain water and the roots will suffocate or be at risk of disease. There are ways to test the planting site (ideally prior to planting) like Digital Soil Meters so that any issues may be addressed. Amendments, like coco-fiber medium, will help to properly distribute water and help avoid future root issues. Learn more about preventative measures when planting in a location that retains water in our article, Plan Ahead for Rainy Weather.

Animal damage, like that which is caused by voles, can severely affect healthy root systems and prove fatal for any plants and trees – even established ones. These animals feed on the root systems of plants, which causes what may appear to be water-stress, chlorosis, and other issues. They also tunnel around the root systems, causing additional damage or even leaving a plant loose in the ground and at risk of falling over. There are certain non-toxic repellents that act as irritants to help ward off damage-causing animals, like voles, rabbits, and deer and protect your plants as well as their roots.


Whether you’re planting something new or caring for an old favorite, don’t forget to keep the roots in mind. If they are healthy and properly cared for, you’ll have much more success when it comes time to bloom or fruit.
