It is often stated that the roots of the fig tree They are dangerous, but is this really true? Are we looking at a tree with roots so strong that they can cause damage?
Let's resolve these doubts by learning a little more about the root system of this tree with sweet and delicious fruits.
The root system of the fig tree: a complex underground network
What we see of trees is their impressive external structure, but beneath the ground the roots form a complex network that anchors them to the earth and is essential for their growth and development.
The root system of the fig tree is characterized by being superficial, since the roots are found in the first 50 centimeters of the soil and extend horizontally. However, they can occupy a ra goodbye that is several times the diameter of its cup.
The roots are numerous, thin and branched. These characteristics allow them to form a dense network that facilitates the absorption of both water and nutrients.
Although the root system is superficial, it is extremely robust and resistant. Therefore, it can penetrate compact and rocky soils.
Another notable aspect is that it has a great capacity for exploring the ground. It can be extended greatly and make the most of the available resources.
Growth pattern of fig tree roots
The pattern we can observe in each specific case depends on factors such as the type of soil, the availability of water, whether the tree has to compete with other plants or the temperature. But, in general terms, the most common ones include:
- Taproots. Although they are not as marked as in other species, it is common for fig trees to develop a main root that penetrates vertically into the ground and is responsible for providing stability.
- Lateral roots. These branch from the main root and spread horizontally, creating a dense network that absorbs water and nutrients.
- Adventitious roots. They emerge from the trunk or branches. Their function is to allow the tree to adapt to adverse conditions and to propagate vegetatively.
A survival system
It is not by chance that the roots of the fig tree have these characteristics. This root system is an evolution that allows these trees to survive in different environments.
Because the superficial and extensive roots allow make the most of soil moisture, making the tree resistant to drought.
On the other hand, since they are strong roots, they can explore large volumes of soil, moving away from the taproot zone.
This ability to extend also gives the fig tree advantage when competing with other plants for water and nutrients.
Are fig tree roots dangerous?
If we review a List of trees with aggressive roots We will probably not encounter the fig tree. However, in practice they can become a problem in some cases, due to the capacity for extension we have been referring to.
These roots are said to be dangerous for the following reasons:
- Extension capacity. They are constantly searching for water and nutrients, which results in horizontal expansion over a great distance from the tree.
- Force. They are strong roots that can penetrate hard soils. They are not strong enough to cause cracks and fissures themselves (normally), but they can take advantage of the presence of these roots to spread and aggravate the damage.
- Search for humidity. To access water and nutrients they can grow upwards through cracks, which can damage walls and pavements.
Therefore, It is not advisable to plant a fig tree near a house. or any other type of construction. During the first few years nothing will happen, but in the long term the growth of the roots can cause structural damage.
It is also not advisable to plant this tree in very compact soil. In this case, the roots will look for other ways to expand and this could lead to them colliding with pipes or foundations and damaging them.
How to prevent damage caused by fig tree roots?
The roots of this tree are somewhat dangerous, but that doesn't mean you should give up on it. If you follow the guidelines we are going to show you, you can have a fig tree in your garden and not suffer any problems.
Variety Selection
Start by choosing a fig variety that has a root system that is not too invasive. It is best in these cases to choose a hybrid specifically developed to have more controllable roots.
Strategic planting
Leave a Considerable distance between the fig tree and any structure (a house, a pool, a wall, etc.) If possible, plant the tree in a large, green area that is away from paved areas or pipes.
You can also consider the option of Growing Fig Trees in Large ContainersOf course, this will require some special care so that the tree can develop.
Supports Preventive Maintenance:
Fertilize the tree properly so that it has the nutrients it needs at its disposal and does not have to resort to spreading its roots too much to find food.
Water properly to encourage uniform root development and prevent them from searching for water in undesirable areas.
At the time of planting, install Physical barriers such as root plates or underground containers so that the root system cannot grow in certain directions.
If necessary, contact an arborist to perform safe and effective root pruning.
As far as possible, Prune the tree regularly to keep it at a manageable size. This will also affect root development.
In any case, carry out periodic inspections to detect any damage that the roots may be causing and take corrective measures as soon as possible if you notice that something is wrong.
Fig tree roots can be problematic, but with preventative measures you don't have to worry.
