A few days back due to strong winds a peepal tree(i.e. Ficus religiosa or sacred fig) was partially uprooted near my house. It is approximately at a 45° angle. It is 7-8 meters tall. Almost half the roots are out of the surface. How can i fix it?
When we travel in hurricane-prone regions such as the low lying islands of the Bahamas it is a fairly common sight to see fruit-laden trees supported by sturdy forked sticks at a precarious angle and surviving quite well. The problem is that when the roots are pulled from the ground they are subjected to the drying winds and desiccate rapidly making it difficult for them to re-establish themselves if reintroduced to the ground. And even if they do form new roots, the tree is weakened on that side making it vulnerable to the next prevailing wind from that direction.
Massive root loss often triggers a distress crop of fruit; the weight of the fruit only contributes to the difficulty, pulling the tree even further over on the leaning side. So for fruiting crops there is a vested interest in keeping that tree going just to get the crop while you work on a replacement tree. But a replacement may take a while to obtain either by home grown or purchase, and may take some time to achieve the size of the existing, which is why a supply of heavy forked sticks and big dimension lumber comes in handy.
The fruit of the F. religiosa is not significant as food, so we can set that aside for a moment. However in some countries this Ficus is regarded as a religious symbol - there may be local sensitivities with respect to keeping specimens in good order. No doubt it will be easy for you to gauge from discussions with neighbours whether this is an issue.
