Does Olive Tree Have Invasive Roots - Olive Tree Root Systems

Olive trees have shallow, widely-spreading roots and a robust tap-root. Even though they occasionally appear above ground, shallow roots are found on the top soil.

While the tap root is the source of the tree's stability, the shallow roots add to it. Furthermore, most of the moisture is absorbed by the shallow roots and used by the plant. In climate conditions resembling a drought, the tree's tap root allows it to absorb moisture.

Olive tree roots spread out slowly, measuring about three feet wide and five feet deep. The classification of invasive roots does not apply to them.

Olive Tree Root System Explained


Olive tree roots are not invasive and don't spread quickly. They grow slowly and carefully, causing no harm to the soil or water resources around them. Additionally, the roots of olive trees aid in the soil's nutrient absorption, which enhances plants' general growth.

On the other hand, if you have a large olive tree, its roots may start to spread a little. There are a number of causes for this, one of which is the olive trees' extremely robust, protracted, and deep roots.

Before you plant an olive tree in your garden, you should speak with the local planning authority if you live in a place that frequently floods or has other water-sucking problems.

If you don't take this action, you might encounter some issues down the road.

Tea Olive Tree

The tea olive tree's roots do not spread. To protect the soil and water sources of the tree, the roots of the tea olive tree expand gradually and carefully. Additionally, they aid in the soil's nutrient absorption, which helps plants grow more effectively.

Additionally, the roots of these plants can spread a little bit if the trees are grown in a region that frequently floods or experiences water-sucking problems.

Fruitless Olive Tree

Olive trees that never bear fruit do not have invasive roots. The fruitless olive tree is a common ornamental plant that does not spread aggressively into the garden and does not interfere with other plants in the garden because it does not spread aggressively.

The plant's roots can grow a little further if it is raised in a flood-prone area.

Sweet Olive Tree

Throughout Europe and the United States, the sweet olive tree root is an invasive pest. A tree with aggressive roots has the potential to harm other trees, soil, pipelines, and other structures due to the aggressive way in which they spread.

Wild Olive Tree

In most places, invasive wild olive tree roots exist. Because of the tree's rapid growth, its roots frequently try to access nutrients from below the ground to support this growth.

Additionally, due to their sturdy branches and leaves, wild olive trees can easily cause damage to property.

Dwarf Olive Tree

It is not invasive to dig up dwarf olive tree roots. Although it might have a root system that spreads widely, this is typically caused by its small size and scarce resources rather than by an aggressive nature.

Furthermore, the dwarf olive tree does not appear to have a tendency to grow aggressively, and because its branches are much weaker than those of a typical olive tree, it is unlikely that it will grow aggressively.

Russian Olive Tree

Russian olive trees are invasive. Despite the fact that its roots are not hostile, if left unchecked, the plant's vigorous growth and deep roots could severely harm other plants.

Additionally, the Russian olive tree spreads aggressively through underground roots, so if you want to keep it under control, it's crucial to maintain the plants and surroundings around it.

Arbequina Olive Tree

There is no proof that the arbequina olive tree is invasive. The plant has no negative effects on the other plants in the garden, despite the fact that its roots can spread quickly.

The fact that it is a well-liked ornamental tree raises the possibility that it could be invasive in some areas.

Kalamata Olive Tree

In most places, kalamata olive tree roots are invasive. Because of the tree's deep roots and vigorous growth, it is vulnerable to significant damage if it is not kept under control.

Does Olive Tree Have Deep Roots?

The olive tree has extensive roots that delve far beneath the surface. An organism's root system is made to draw the most nutrients possible from the soil beneath it and to get to that soil in order to support its growth.

Because they can grow very quickly, olive trees may be forced to become aggressive and start causing property damage if they aren't given enough water or other resources.

Due to its extensive roots, olive trees frequently have uneven weight distribution. Beams and supports might be bent and broken as a result of a windstorm or earthquake.

Furthermore, once established, olive trees can be challenging to remove because they have been known to disperse invasive plant species.

How Deep Are Olive Tree Roots?

Olive trees have deep, five-foot-deep roots that can be found. Because olive tree roots have the potential to spread aggressively, it's critical to monitor them and take appropriate action if they start to pose a threat in the future.

The strength and general health of the tree will increase as the depth of its roots increases. In addition, if a tree's root system is found to have any damage or disease, it will quickly spread throughout the tree as a whole.

The roots of an olive tree have an average diameter of 2.5 inches. A tree's root can extend three feet from the tree's trunk.

Olive tree roots, on the other hand, can grow up to about five inches in diameter, depending on the species of tree.

Can Olive Tree Roots Damage Foundation Or Pipes?

Although the roots of olive trees have the potential to harm your foundation or pipes, this is usually only a minor issue that can be resolved without the need for any major home renovations.

Olive trees can flourish in areas with low soil moisture levels, and since they frequently bury themselves deeply in the ground, their roots also do the same.

This tree has a plethora of roots, and if any of them come into contact with sewage or water systems, they could damage the structure.

Thankfully, the majority of the harm that olive tree roots can do is typically restricted to tiny fragments of pipe or foundation wall that are situated close to the tree's trunk.

Depending on how serious the issue is, it might be necessary to remove the entire olive tree to fix it.

However, this is infrequently required and should typically only be done as a last resort after trying every other option and coming up empty-handed.

If an olive tree is close to your house, be cautious of its roots. The majority of the time, however, olive tree roots are merely a minor issue that can be fixed without the need for any significant tree maintenance.

Do Olive Trees Spread Or Multiply?

Olive trees don't grow or spread out. Planting olive trees in pairs is the most effective way to make them grow. If two olive trees are planted close together, they will grow more successfully and their root systems will never cross.

The spread of roots can be a problem in locations where there are other woody plants nearby, like pine trees.

If their root systems cross, they will eventually become entangled and come into conflict. Soil instability may lead to a weak or unwell tree. Olive trees typically develop in groups, and each group gives birth to a few fruit trees.

If you plant an olive tree from a seed or a cutting from an existing tree, the likelihood of it spreading or multiplying is significantly higher.

However, if you intend to plant an olive tree in a new location, you should be aware of this problem and think about planting in pairs or clusters. Limiting root spread with this technique will keep your tree healthy.


Preventive Measures to Keep Olive Tree Roots from Becoming Invasive

It's unnecessary to worry that olive trees' roots will become destructive if you grow them in pots. To prevent the roots from spreading too far, it is wise to take preventative measures if you choose to plant trees in your yard.

Choose a Suitable Space for the Tree's Size

Olive trees should be planted in areas that will allow for the roots to grow as the tree matures because their roots are as wide as their canopy.

To keep fences, homes, and sewer lines safe, plant the trees far from these objects. The best practice is to keep an olive tree 20 feet away from your home because, when mature, some olive trees' roots can extend that far.

Mature olive trees come in a wide range of sizes. Some trees grow to be enormous, while others stay comparatively small.

Therefore, thoroughly research the type of olive tree you want to plant to make sure it will grow in your yard. You have a wide range of options, which is good.

The best trees for small gardens are those that don't grow too big. These olive trees include the 15–20 foot-tall Arbequina and Nocellara Del Belice varieties. A different option is to plant 8 to 10 foot tall dwarf olive tree species.

Use Root Barriers

Root barriers redirect root growth, causing tree roots to grow downward rather than sideways. As a result, they permit you to plant olive trees close to buildings because their roots won't spread out and harm the structures.

High-density polyethylene (HDPE), fiberglass, or metal are impermeable materials for root barriers. To increase the likelihood that these barriers will be successful, you can spray them with a growth inhibitor.

Some root barriers are constructed from mesh. These barriers are permeable, so they do not function as effectively as those that are impermeable.

Final Thoughts

In conclusion, the majority of olive tree roots are not invasive. However, invasive species include sweet olive trees, wild olive trees, and Russian olive trees. Even though olive tree roots are not invasive, they can still erode foundations and pipes. A root can extend five feet below the surface.
