Sir, This is with reference to your recent WhatsApp Us titled ‘Will this oxygen supplier at Railway Station survive?’ It is a wrong concept to say that space is necessary around the stem of trees to allow the water to reach the roots. Generally, these trees belong to the adventitious root system where the roots grow laterally to quite a distance of several metres. It is not very uncommon even to see the roots making their way into sewage lines in search of water. The other type of roots is the ‘Tap root system’ where the root grows deep down vertically for a considerable distance. As such water seeping from around the stem may not be of much significance.
