Did you know that what you see above ground in your plants is really determined by what's hidden underground? What happens underground, where the plant roots live, drives plant growth. The bigger and healthier the root system, the bigger and healthier the plant.
What do healthy roots do?
Many things. First, they provide the anchor needed to keep a plant in place. More importantly, roots are the lifeline of a plant, taking up air, water, and nutrients from the soil and moving them up into the leaves, where they can interact with sunlight to produce sugars, flavors, and energy for the plant. That is the magic of how things grow.
Additionally, biologists have recently discovered that roots actually secrete compounds that affect the microorganisms in the soil, doing things like helping protect the plant from disease and encouraging it to absorb nutrients from the soil. There is a whole world of activity underground! You can read more about it in our article "The Soil is Alive. Really!"
So how do you get a system of good, healthy roots? Remember seven words: "Healthy, deep soil. Adequate moisture and nutrients." If everything you do in your garden works toward that, your plants should thrive. (Granted, there are ugly wilts and other diseases that can ruin even the best-laid plans, but you can learn more about those later if you need to.)
To create a good environment for roots, fill containers and raised beds with the right soil for growing. Use premium quality potting mix, such as Miracle-Gro® Potting Mix, in pots; in raised beds, use a raised bed soil like Miracle-Gro® Raised Bed Soil, which is less fluffy than potting mix but not as dense as garden soil. Garden soil, both the bagged kind and the kind taken from an actual in-ground garden, is too heavy and will over-compact when used in a raised bed or container. Roots need air and space, and won't grow as well in compacted soil.
In-Ground Gardens
If you have an in-ground garden, add lots and lots of organic matter — think bagged or homemade compost— to the ground. Some municipalities will even deliver a truckload of composted leaf litter for a fee. Or, you can buy it from a garden center. Don't bother adding topsoil; just get compost and work it into the soil that you already have. (Be sure to add more every year because it decomposes.)
Water and Feed Plants Regularly
Healthy roots need a regular source of moisture, so make it a habit to water regularly. A good rule of thumb is to make sure plants get an inch of water per week through rain and/or watering. (Plants in containers may need more.) You'll also want to apply a continuous-release fertilizer, such as Miracle-Gro® Shake ‘n Feed® Tomato, Fruit & Vegetable Plant Food throughout the season. (As with all fertilizers, follow the directions on the label.)
When you garden, always think about the roots. Ask yourself, what am I doing to make sure that these little roots will grow big and happy? Loose soil, adequate water, and plenty of nutrients are the keys to healthy roots and productive plants.
First, they provide the anchor needed to keep a plant in place. More importantly, roots are the lifeline of a plant, taking up air, water, and nutrients from the soil and moving them up into the leaves, where they can interact with sunlight to produce sugars, flavors, and energy for the plant.
Roots play an important role in nutrient intake, similar to the way leaves photosynthesize — a process of converting light energy into food. The roots help to bring soil nutrients up through the vascular system of the plant or tree and even work to store nutrients during dormant periods.
Roots are one of the three organs of a plant. The primary function (most important job) of the roots is to take in water and nutrients. Just like people, plants need water and nutrients to grow! Roots also anchor the plant, and help the plant survive periods with too much or too little water and nutrients.
If the roots are white or tan colored, succulent when you pull on them and have fleshy white tips, then your root system is healthy. Remember, some plants have fine roots and you may need to examine them with care, even use a magnifier. Without robust root development plants can't thrive.
Roots absorb water and minerals and transport them to stems.They also anchor and support a plant, and store food. A root system consists of primary and secondary roots. Each root is made of dermal, ground, and vascular tissues.
Roots perform a number of important functions for plants as they help anchor the plant, absorb and store water, food, and nutrients. For these reasons, a healthy plant must have a healthy root system.
Roots are the important underground part of all vascular plants. This part of the plant is mainly responsible for anchoring it down into the ground and absorbing the essential mineral elements, nutrients, and water from the soil. It is also used to store food.
In summary, roots are important because they are essential in solving equations and understanding the behavior of functions. In more advanced mathematics, the distribution of zeros can provide information about the rate of growth of a function.
Roots hold a plant in the soil. Roots also take in water and dissolved minerals from the soil, and in some plants, food is stored in the roots. The main job of stems is to support the leaves. Stems also are important organs for carrying materials between the roots and leaves.
While phosphorus helps in the establishment of a healthy root system at the beginning of plant growth, it also promotes flowering and fruit setting. Potassium, on the other hand, promote root growth. A well-watered soil is more likely to support the growth of plant roots than a poorly watered one.
Make sure not to add too much water as that can cause root rot and clog the space for oxygen, leading to a weak root system. It is best to provide deep watering occasionally to promote a strong and healthy root system.
Tree roots grow best when they have sufficient growing space and well-drained soil with enough oxygen and water (but not too much water). The depth that oxygen can reach depends on the type of soil and amount of compaction, and the most oxygen will be found near the surface of the soil.
Mineral nutrients are broken up into macronutrients and micronutrients. The most important primary macronutrients for plants are nitrogen (N), phosphorus (P), and potassium (K).
Roots are dynamic and their growth is strongly affected by the environmental conditions found in the root zone. To survive and grow, they need Air (gas exchange), Water, Non-limiting Temperature, Carbohydrates, Minerals, Space, Low Soil Density, Microbial Associations and Non-toxic soil chemistry.
There is no question that living roots build soil! Roots provide structure for the soil to hang on to when destructive forces of wind and water occur. Accomplishing this process occurs through the “great exchange” of nutrients and water from the soil in exchange for carbon (carbohydrates) from the plant.
Human being use plant roots as food, clothing, and medicine, and dyes. Some roots like carrots, yam, potato and radish serve the purpose of a storage organ which is used as food by humans. They store carbohydrates and water. Roots are the source of crucial drugs that have the potential to save life.
