I live in Pune, India. The weather these days is like Temp: 15 to 30 deg C, Humidity: 30 to 60%. The sapling bought from a local nursery a month ago, the plant is kept in the shade. We water regularly, and There was no overuse of fertilizer or manure. The transplant was done by the gardener, so I think its safe to say that roots weren't damaged either.
What could be the issue? What do I do?
