It is not advisable to have big trees on loose soil. When heavy wind and rain comes it may uproot these trees. So we should be careful about this.
Using these trees as post guards should not be allowed. They should make their own arrangement for these wires. Either under ground or above ground they should have their own arrangement.
If we want to plant big trees along the road side, proper care should be taken and see that they will withstand heavy winds and rains.

Even this challenging situation would ease
Unfortunately the problem lies in selection of trees for road sides as well as their plantation mechanism. The road side trees should be more straight and ornamental rather than the huge banyan and peepal trees extending their branches over the roads and proving hazards for passing trucks. Another important thing is how they are planted. Normally in our country once the road is complete and footpath are concreted then we make small holes in concrete and dump the trees in that and there is no soil beneath and even if the tree grows it will fall down on the first few rain spells.
We are simply planting trees and counting how many we have planted and making a hue and cry out of that. Strictly speaking a big hole of 1-2 feet diameter and deep in the earth at least to 6 feet and filled with soil so that it connects to the soil beneath is required to plant a tree then only its roots will be firmly fastened to the soil. Once it is deeply planted it will rise with a thick stem and will stand the rains easily. The concrete which killed it earlier will now anchor it from all sides and protect it.
Anyway these are the things known to the contractors but as no one insists them to do so they are happy with their shabby work. There are many advanced countries in Europe where a lot of trees and vegetation is there but they do not have such problem of falling trees with simple rains.
