Various trees and shrubs are only shallowly rooted in the ground. Others are deep-rooted. They are called taproots. These have a long taproot that extends deep into the ground. Below are a few examples.

In a nutshell

  • a taproot is a long main root
  • it grows vertically deep into the ground
  • Taproots are well anchored in the ground
  • easily adapt to unfavorable conditions
  • Lilac, pine and silver fir are deep-rooted

Typical for taproots

Taprooters belong to the group of deep-rooters. A long and strong main root is characteristic of this root system. This has developed from the radicle (radicula) and grows vertically deep into the ground. Diverse side roots arise from the taproot diagonally or sometimes horizontally. It is a heterogeneous root system. Plants with such a root system can easily adapt to extremely unfavorable locations. The most common natural distribution areas of such taproots are therefore mostly in summer-dry regions. They make no special demands on the soil. They grow on sandy, loose or gravelly substrates. It is precisely here that they need firm anchoring so that they do not tip over in stormy times.

Notice: Many heart roots also develop a taproot at a young age. With increasing age, many strong side shoots are formed as with the real walnut (Juglans regia).

frequently asked Questions

What advantages do taproots have over shallow roots?

Since they are deep-rooted, they have a higher stability. The roots do not spread too much and cannot damage buildings or terraces. Since they draw water from deeper regions of the earth, they can easily be planted under. They also contribute to soil improvement.

Is it possible to simply transplant taproots?

Problems can arise with older trees, because the roots must not be damaged. Since it goes deep into the ground, excavation is very difficult. Therefore, trees and shrubs that are deep-rooted should only be transplanted when they are young. They should not be older than three years. Otherwise it can happen that older trees do not grow back.

What should be considered when planting taproots?

Since these plants are deep-rooted, the choice of location must be made carefully. Subsequent transplanting is not recommended. It is important that such plants are not planted directly over underground pipes or cables. Over time they would destroy them. Of course, depending on the size, a certain distance to the neighboring property etc. must be maintained.
