Tree grate (horticulture)

This area is characterized by roots that are particularly high in the ground. Other plants often do not thrive here because the tree roots deprive them of moisture and nutrients and the treetop shadows this area heavily. The grass around fruit tree trunks in an orchard meadow grows only sparsely and low. The roots of some trees, for example the walnut tree , secrete growth-inhibiting substances, so that hardly any other plants thrive in their environment.

The care of the tree grate is one of the horticultural measures. It is not chopped or dug up to leave the roots undisturbed. Mulch can ensure adequate soil moisture and fertilize the tree. In some cottage gardens , daffodils are planted on the tree disc. Because of their numbing ingredients, narcissus bulbs are not eaten by voles . It is therefore hoped that the fruit tree roots will also be spared from the rodents .

In the inner city, the tree grate often needs mechanical protection. To prevent parked vehicles from compacting the soil around the tree grate or damaging the trunk with the bumper, pegs, metal brackets or cover plates are attached. In the pedestrian zone , cover plates let water and air through and make street cleaning easier. The unpaved tree slice in the roadside should not be less than 5 m² in size for ventilation and watering. Since roots grow in all directions starting from the tree trunk, the outline should approximate a circle. Reinforced concrete root bridges enable the area close to the tree to be used for traffic purposes without the root space being compressed or damaged. Additional irrigation systems or openings in the root bridge enable the tree to be watered.

Tree disc (colloquial)

In a broad sense, the term tree / wood disc denotes the narrow section / cross-section of a tree trunk or branch that is created when they are sawn into disks. Such tree grates can be used to determine the age and growth of a tree with the help of the annual rings .

  • Tree disc with annual rings in the Bamsterwald nature reserve

  • Tree disc in the Dreibächel clearing near Morgenröthe-Rautenkranz

  • Tree / wood disc of a sequoia tree with a diameter of 5.4 to 6.3 m, the 80 cm thick cut weighs 7.5 t .

  • Tree slice in the BC Forest Museum

  • Tree slice of the historical "Wentzelbuche" ( Wellingsbüttel manor )

  • Petrified tree disc ( Church of John XXIII. )
