Apple Tree Root System – Are Apple Tree Roots Invasive?

Sharing is caring!

The apple tree is one of the most popular landscaping plants in the world. Known for their beautiful fruit and blossoms, they come in a variety of shapes and sizes. However, you may not know that apple trees have a root system as well. 

Could apple tree roots cause invasive species of plants? Would they damage other plants, damage the soil, and create problems? Let’s examine that.

Apple tree Root System Explained

Apple trees have roots that are thin, long, and grow below the ground. The roots grow vertically and directly into the soil. The roots support and nourish the apple tree branches and foliage. The roots also help distribute water and nutrients around a plant, which is crucial to its health.

Roots of apple trees can be invasive if they grow too deep, spread too wide, or connect to other plants. In general, apple tree root systems are not invasive. 

It is usually not necessary for apple trees to spread beyond their original planting area, and they generally cause little harm to surrounding plants or soil.

Custard apple tree:

Custard apple trees have deeply rooted vines. Trees of this type are less invasive than standard apples. Their roots may connect with other plants. 

Rooster apple trees may require more pruning than other types of apple trees to stay within bounds, but once established, they are generally not too troublesome.

Dwarf apple tree:

Dwarf apple trees are apple trees with very thin roots. Standard apple trees are usually more expensive. They may be less desirable to some homeowners because their thin roots may be more vulnerable to predation or damage from wind and hail.

Fraser island apple tree:

Fraser Island apples are a variety of apples well known for their deep roots. Trees of this type do not invade other areas. Nevertheless, it should be pruned more frequently to stay in check.

Sugar apple tree:

The sugar apple tree is a type of apple tree that bears sweet fruit. The deep roots of these trees can spread and connect to other plants around them, making them more potentially invasive than other varieties. 

Honeycrisp apple tree:

Honeycrisp apple trees are known for their colorful fruit. Their deep roots can spread and connect to other plants around them. However, these roots do not invade other plants.

Kei apple tree:

The roots of Kei apple trees are not invasive. It is an attractive little tree that is useful for landscaping and fruit trees. Once established, it requires little maintenance and grows well in moist but well-drained soil.

Pink lady apple tree:

Pink Lady apple trees are a concern due to their ability to spread quickly and become difficult to control once established. However, in general, they are not invasive to other trees and soil.

Crabapple tree:

The crab apple tree is not invasive, but it can spread rapidly if given the chance. It requires little maintenance once it has been established and grows best in moist, well-drained soil.

Fuji apple tree:

Fuji lady apple trees are not invasive and don’t threaten native plant communities. The tree is commonly grown as an ornamental in North America due to its large, beautiful fruit.

Gala apple tree:

Gala apples are not invasive, but they can spread rapidly if they are given the chance. Once they are established, they do not require much maintenance once they are growing in moist, well-draining soil.

Does Apple tree have deep roots?

The roots of the apple tree entwine themselves deeply into the ground. Because of this, it can grow rapidly and form connections with other plants nearby. This doesn’t necessarily mean that they are planted in soils that have a lot of healthy nutrients, but that’s what they often say.

The majority of apple trees grow in soils that are relatively low in nutrients and supplements. However, apple trees can make up for any deficiencies in these essential resources due to the roots that access these resources. 

In most soils, apple trees do well, unless your soil is specifically unsuitable for the growth of apple trees.

How Deep Are Apple Tree Roots?

Within 3 to 5 years, apple tree roots can grow as deep as 15 to 20 feet underground with the right soil conditions and nutrients. It is because apple trees can draw water from a resource called groundwater during the growing season.

Additionally, this system enables apples planted close together to share resources more evenly and, consequently, to produce better quality fruit. 

The design is particularly beneficial for soil stability and prevents the trees from becoming uprooted and dangerous during heavy rain or snowstorms.

Are Apple Tree Roots Invasive?

The roots of apple trees are not invasive. They do indeed spread rapidly, however, this is often because the tree is given the opportunity and thrives well in moist, well-drained soils. 

The root system of an apple tree is quite beneficial as it acts to stabilize soil and promote the growth of the tree.

Additionally, the leaves of an apple tree provide a green cover on the ground beneath them, which benefits both plants and wildlife in the area as well. 

It is known that apple trees proliferate prolifically through underground stems that grow at a rapid pace, creating a dense canopy of foliage. There is no guarantee that you will grow a multitude of apple trees throughout your yard in a short period.

What kind of root system does an apple tree have?

In moist soils, apple trees have a deep root system. In addition, apple trees create their underground systems to access groundwater resources. These are the root systems of an apple tree.

Fibrous Roots:

Apple tree roots are known as Fibrous Roots because they grow quickly due to their many small strands. The roots of apple trees are vital for promoting growth and stabilizing the soil, thus ensuring overall tree health.

Deep trap roots:

Apple trees have deep roots that can spread out in moist soils and help to stabilize the soil as long as they are planted in moist soils. 

In addition to that, apple trees also create their underground systems to access groundwater resources whenever required, which is why they do well in moist, well-drained soil.

Feeder Roots

Trees that produce apple plants may also produce feeder roots that help to support the tree when it is located in a windy or shrubby area. These feeder roots can grow up to 12 feet in length. 

Furthermore, apple tree branches may also produce small twigs that help spread the fruit and provide shade to the ground.

How big are Apple tree roots?

Roots of apple trees can reach a length of 15 to 25 feet and a diameter of 20 feet. However, the size of apple tree roots varies from tree to tree. 

In the first year, the roots reached a maximum depth of 8.8 feet and a lateral spread of 10 feet, followed by 13 feet and 20 feet the following year.

The maximum lateral spread and depth were 25 feet and 18 feet respectively during the third year. The roots, however, only reached a maximum depth of 14 feet and a lateral spread of 12.5 feet the following year. As the tree’s root system matured, its growth rate slowed.

Can Apple tree roots damage foundation or pipes?

Apple tree roots can damage foundations or pipes if they are not properly secured. Apple tree roots grow quickly. So, it is important to ensure that they are well-anchored and do not damage any of the nearby infrastructures. 

Before installing a new foundation or piping, you may want to dig a trench around the apple tree’s roots to prevent this.

Look for any gaps in your driveway, walkway, garage flooring, or drainage systems where the roots of Apple trees have grown through the surface layer of soil. Consequently, you should contact a professional to remove and fix the damaged area.

Do Apple trees spread or multiply?

Root systems and underground stems allow apple trees to spread and multiply. They reproduce by division of the stem. From each graft union (where two different types of trees are joined together), apple trees can produce up to three new individuals.

However, the root systems of Apple trees can penetrate several feet beneath the surface. Hence, they can spread rapidly even in areas where there are no new trees.

Final Thoughts

The apple tree root system is generally not invasive, but it does spread widely. Additionally, the roots of some varieties can penetrate as deep as 25 feet into the ground. Other varieties may reach depths of several feet. The apple tree is known for its feeder, fibrous and deep roots.
