Root curtain
What can be done when tree roots need to leave their normal environment for an extended period, during digging and excavation in the tree’s direct vicinity, for example?
In this case, a so-called root curtain is applied – a procedure in order to prevent the roots that are to be retained from drying out, becoming damaged or dying with the aid of special substrate in the root area and to promote the re-formation of roots by means of fertilizers and soil improvement preparations.
Soil ventilation and deep fertilizing
The soil climate of many urban trees undergoes permanent disruption as a result of gritting salts, and the roots receive insufficient oxygen as a thick layer of concrete is placed around the trunk.
This situation calls for long-term measures in order to create a fully functional ventilation system for the roots beneath the surface. Thus, by means of feeding in a deep fertilizer, for example, the tree is supplied with both an immediately effective reservoir of nutrients and a long-term fertilizer.
Via these measures, vital functions such as gas exchange, water supply, water retentivity and functioning soil ventilation are assured for a longer period.
Root ice treatment
It may occasionally occur that tree roots grow too far downwards or spread far too superficially and thus constrict pipes – if this is the case, a patent from Baumchirurgie Saller for the ice treatment of roots comes into application; tree root growth is halted.
